Planning a Renovation in York Region: Design Build, and Who We Recommend
Why the firm that draws your renovation should be the firm that builds it, what a design build process actually looks like, how to judge one, and the GTA firm we send our own clients to.
A Recommendation From Kirby Chan & Co. Real Estate Team
This page is a referral, so read it as one. Kirby Chan & Co. Real Estate Team is a real estate team, not a builder, and the question we get asked most often after a purchase is who should do the work. Rather than hand people a list, we tell them what to look for in a renovation firm and then name the one we send our own clients to. The disclosure about our relationship with that firm is in section nine, and we would rather you read it before the recommendation than after.

We will tell you what the property can take before you design anything
Quick takeaway: Most renovations that go wrong go wrong in the gap between the drawing and the build. A designer produces a plan, a separate contractor prices and builds it, and when the two disagree about what was intended the homeowner is the one standing between them with no way to settle it. A design build firm removes that gap by holding both roles, which means one party is accountable for whether the finished room matches the plan. The firm we recommend for this work in Toronto and the GTA is Purpose Built Designs, a small team run by Ryan and Kathy Mach that handles design and construction together across whole-home renovations, kitchens, bathrooms, basements and custom homes. We are connected with that business, which is disclosed in section nine, and you should get other quotes regardless.
What This Page Covers
1. The Gap Where Renovations Go Wrong
Start Here Between the Drawing and the Build
The usual way a renovation is organised is that one party designs it and a different party builds it. A designer or architect produces drawings, the homeowner takes those drawings out to contractors for pricing, and the winning contractor builds what they understand the drawings to mean.
That arrangement has a structural weakness and it shows up at the same point every time. Drawings are never complete. There are always details that were not specified, conditions behind a wall nobody could see, and decisions that have to be made on site. When the designer and the builder are different companies, each of those moments becomes a question of whose responsibility it was, and the homeowner is the one standing in the middle with no way to settle it.
The predictable consequences are change orders that were not budgeted, a timeline that slips while two parties wait for each other, and a finished result that does not match what the homeowner thought they were buying. A great many renovation disputes are not about bad work. They are about an unresolved disagreement between the drawing and the build.
Design build removes the gap by putting both roles in one firm. The people who drew it are the people who build it, the pricing reflects what the drawing actually requires because the same firm has to deliver it, and when something unexpected appears behind a wall there is one party accountable for resolving it rather than two parties negotiating.
It is not automatically cheaper, and anyone telling you it is should be asked to show you why. What it is, reliably, is clearer about who is responsible, and on a project with your house torn open that is worth more than most people expect.
2. Who Purpose Built Designs Are
The Firm We Recommend A Small Team, Design and Build Together
Purpose Built Designs is a design build firm working across Toronto and the Greater Toronto Area. They describe their own approach as globally sourced finishes, locally crafted, and their work covers high-end renovations and new homes.
It is run by Ryan and Kathy Mach and it is a small team. We are naming that deliberately, because it is the most useful thing you can know about them before you call. On a small team the person who takes your first conversation is involved in your project, and the design and the build are not handed between departments. The trade-off is capacity: a small firm takes on fewer projects at once, so timing matters and you should ask about availability early rather than assuming a start date.
The services they list are whole-house renovations, kitchens, bathrooms, basements, custom homes from first drawings through to move-in, and interior design covering layouts, cabinetry, lighting and finishes, planned in three dimensions so you can see the result before committing to it.
They offer a consultation with Ryan Mach before you commit to anything, which is the right way to use them. A conversation about whether what you want is possible in the space you have, and roughly what it involves, costs you nothing and will tell you more than any amount of reading.
The sections that follow describe what each kind of project involves and what to establish before you start. Everything in them applies whichever firm you hire.

3. Whole-Home Renovations
The Project Where Design Build Matters Most
A whole-home renovation is the project with the most decisions, the most trades, the longest timeline and the most opportunities for a plan and a build to drift apart. It is also the one people most often attempt by assembling their own team, and the one where that approach causes the most difficulty.
What makes these projects work is sequence. Structural decisions before layout, layout before finishes, mechanical and electrical routing before anything is closed up, and permits in place before the work they govern begins. Get that order wrong and you are opening walls twice, which is where budgets actually disappear.
What to establish before you start. What is structural and what is not, since that determines what is possible and what it costs. Whether you will be living in the house during the work, and if not, where you will be and for how long. What happens to the timeline and the price if something unexpected is found, because on an older home something usually is. And what the firm's process is for decisions you have to make mid-build, since on a project this size there will be many.
Where a real estate conversation helps first. Before you commit to a whole-home renovation, it is worth knowing what level of finish your street and housing type actually support, because there is a ceiling and spending past it is spending you do not recover. That is a comparables question and it takes us an hour. Our guide to Richmond Hill neighbourhoods explains why that ceiling differs so much street to street.
If you are renovating to live in rather than to sell, that ceiling matters less and your own preferences matter more, which is the better reason to do this work at all.
4. Kitchens
Layout First, Finishes Second
A kitchen is the room where design and construction are least separable, which is why it is the clearest argument for a design build firm. The cabinetry has to fit the space that exists, the appliances have to fit the cabinetry, the services have to reach where the appliances are going, and the stone has to be templated against what was actually built rather than what was drawn.
Purpose Built Designs handle kitchens as layout, cabinetry, stone and lighting together. That grouping is the right one, and it is worth understanding why. Lighting in particular is the element most often added at the end as an afterthought, and it is the element that most determines whether a finished kitchen looks like the drawing. Task lighting, under-cabinet lighting and the ceiling plan all have to be decided while the ceiling is open.
The question to settle before anything is ordered is whether you are changing the layout or keeping it. Keeping the layout and replacing everything in place is a materially different project from moving the sink, the range or a wall, because the second brings plumbing, ventilation and sometimes structure into play. People often discover which project they are doing after they have already budgeted for the other one.
Being able to see it in three dimensions before committing matters more in a kitchen than anywhere else, because a plan view does not tell you how a run of cabinets feels or whether an island leaves enough room to open a dishwasher with someone standing behind it. Ask to see the design modelled rather than drawn flat.
One honest note if you are selling rather than staying: a full kitchen rebuild is usually the weakest pre-sale investment available, and our guide to renovating before selling explains why. Build the kitchen you want if you are the one going to use it.
5. Bathrooms
Small Rooms, Unforgiving Work
Bathrooms are small, which makes people underestimate them. They contain more trades per square foot than any other room, and the consequences of poor execution are worse than anywhere else, because the failure mode is water inside a wall.
Purpose Built Designs cover ensuites, family bathrooms and powder rooms, and the distinction between those three is not cosmetic. An ensuite is a private room where your own preferences govern. A family bathroom has to survive heavy shared use and should be specified for that. A powder room is the one guests see, which makes it the room where a confident design choice does the most work for the least money.
The part to ask about specifically is waterproofing, and the answer tells you a great deal about any firm. Ask what system they use behind the tile, how the shower is built, and what they do at the junctions where most failures start. A firm that answers that question in detail and without irritation is a firm that has thought about it. A firm that moves you back to tile selection has told you something.
Ventilation is the other quiet one. An underpowered or poorly ducted fan produces the moisture problems that get blamed on the build years later. Ask where it vents to, not just what it is.
Changes to plumbing or electrical in a bathroom commonly require a permit and should be carried out by appropriately licensed trades. Section eight covers permits.
6. Lower Levels and Multigenerational Households
The Question We Are Asked Most A Self-Contained Lower Level Is a Regulatory Project First
The single most common renovation question we get in York Region comes from multigenerational households, and it is some version of this: can our basement become a self-contained space with its own kitchen and entrance, so that parents or adult children have independence without anyone moving out.
The answer is almost always that it depends on the regulations before it depends on the design, and that order is the thing people get backwards. A self-contained suite is not a finished basement with a kitchenette added. Where it constitutes a second dwelling unit it engages municipal zoning, the building code and fire separation requirements, and the things that determine feasibility are unglamorous: ceiling height, window sizes and egress, a separate entrance, fire separation between units, and parking.
Those requirements differ between Richmond Hill, Markham and other municipalities, and they change. Nothing on this page should be used to decide whether your basement qualifies. The feasibility answer comes from your municipality and from a firm that has done the work there, before any money goes into drawings.
Purpose Built Designs list basements among their services, and a design build firm is the right structure for this kind of project specifically because feasibility, design and construction are so tightly connected: a ceiling height or an egress window determines the layout, and the layout determines everything else. Ask them directly about their experience with self-contained suites and with your municipality, because that specific experience matters more here than general renovation skill.
Why this is worth doing properly rather than informally. An unpermitted second unit creates problems with insurance, with a future sale and potentially with the municipality, and those problems surface at the worst possible moment. Our guide to renovation permits in Richmond Hill and Markham covers the process.
If the alternative you are weighing is buying a different house that already works for the whole family, that is a comparison we can run against the renovation, and our guide to multigenerational living in Richmond Hill and Markham sets out both paths.
7. Custom Homes
First Drawings Through to Move-In
Purpose Built Designs build custom homes from the first drawings through to move-in, which is the other project type where holding design and construction in one firm changes the experience rather than just the paperwork.
The part that decides a custom build is the site, and it is decided before you design anything. What the zoning permits in terms of footprint, height and setbacks, what the lot can take, what services are available, and whether there are easements or conservation considerations. A design produced before those answers is a design that gets redrawn.
If you are buying a lot or a teardown in order to build, that is where we come in first, and it is worth a conversation before you make an offer rather than after. What the zoning allows, what comparable new builds in that pocket have achieved, and whether the numbers work at the price you are considering. A lot that looks inexpensive can be expensive once you know what it permits.
What to establish with any builder before committing. How the contract handles changes and allowances, what is included as against what is an allowance you will exceed, what the schedule assumes and what happens if it slips, and what warranty coverage applies to the finished home. New home construction and builder licensing in Ontario sit within a regulatory framework and those are questions for your lawyer and the relevant authority.
For the regulatory side of buying a newly built home from a builder, our guide to buying pre-construction in Ontario covers the framework, though a custom build on your own lot is a different arrangement from buying a unit from a developer.
8. How to Judge Any Renovation Firm, Including This One
Apply These to Purpose Built Designs Too Ten Questions, and Permits Is the One That Matters Most
1. Do you pull the permits. The answer should be yes as a matter of routine. A firm that offers to avoid permits is offering you a saving you will pay for during a future sale, an insurance claim or a municipal inspection. This is the single most important question on the list.
2. Are you insured, and can I see the certificate. Liability coverage and workers' compensation coverage, current, in writing.
3. Who is licensed for the plumbing, electrical and gas work, and are they employees or subtrades you have worked with repeatedly.
4. What is in the quote and what is an allowance. Allowances are where quotes diverge from final costs, and comparing two quotes without knowing which allowances each one contains tells you nothing.
5. How are changes handled, priced and approved once work is underway.
6. What is the payment schedule, and what is the deposit relative to the total. Be wary of a large payment demanded before any work begins.
7. Can I see two recent projects like mine and speak to those homeowners, including one where something went wrong. Every firm has one. The useful question is how it was resolved.
8. Who is on site day to day, and who do I contact when there is a problem.
9. What is your current availability, which matters particularly with a small firm.
10. Get at least three written quotes with comparable scope, and read the scope rather than the headline figure. That applies to Purpose Built Designs as much as to anyone else, and we would say the same thing if you asked us about our own services.
9. Our Disclosure, and Why We Still Recommend Them
Read This Before You Weigh the Recommendation We Are Not a Neutral Source on This
DISCLOSURE PARAGRAPH, CONFIRM WORDING WITH BROKER OF RECORD OR LAWYER BEFORE PUBLISHING: Purpose Built Designs is a business we are connected with. That is why this page names one firm rather than listing every renovation company in the area, and you should weigh the recommendation knowing it. We receive no fee from you for an introduction. If you would prefer a recommendation from someone with no connection to the firm, say so and we will tell you that plainly rather than steer you.
Having disclosed that, here is the honest case for the recommendation. We are a real estate team. Our clients ask us who to use, and the thing we are protecting is our own credibility with those clients, which does not survive sending people to work we would not stand behind. A referral that goes badly costs us more than it earns.
And here is what the recommendation does not cover. We are not qualified to assess structural design, waterproofing detail or code compliance, and we do not supervise anyone's work. Your contract is with them and not with us. Verify the insurance, check the references, read the scope, and apply every one of the ten questions in section eight to them as rigorously as you would to a firm we had never heard of.
If after doing all that you choose a different firm, that is a good outcome and we will still help you with the real estate side of whatever you are planning. We would rather be useful than be followed.
10. How to Start, and the Order That Saves Money
Five Steps, and the Sequence Is the Point
1. Decide what the renovation is for. To live in, or to sell. The answer changes every subsequent decision, because renovating for yourself rewards your own preferences and renovating for a sale rewards the opposite.
2. If selling is anywhere in the plan, have the real estate conversation first. What level of finish the street supports, what the comparables reward, and whether the work is warranted at all. This is an hour and it has stopped a number of our clients from spending badly.
3. Establish feasibility before design, particularly for a lower level suite or anything structural. Municipality first, drawings second. Paying for a design that regulations will not permit is the most avoidable cost in this whole process.
4. Take the consultation. Purpose Built Designs offer a consultation with Ryan Mach before you commit, and that conversation will tell you whether what you have in mind is possible in your space and roughly what it involves. Use it.
5. Then get your three quotes with comparable scope, apply the ten questions, check the insurance, and decide. Not before.

Frequently Asked Questions
What is a design build firm and why does it matter?
A design build firm holds both the design and the construction of a project rather than the homeowner hiring a designer and then a separate contractor to build the drawings. It matters because drawings are never complete: there are always unspecified details, conditions behind walls nobody could see, and decisions made on site. When the designer and builder are different companies, each of those moments becomes a question of whose responsibility it was, with the homeowner in the middle. One firm holding both roles means one party is accountable for whether the finished result matches the plan. It is not automatically cheaper, but it is clearer about responsibility.
Who do you recommend for renovations in Toronto and the GTA?
We recommend Purpose Built Designs, a design build firm working across Toronto and the Greater Toronto Area on whole-house renovations, kitchens, bathrooms, basements and custom homes, with interior design planned in three dimensions. It is run by Ryan and Kathy Mach and it is a small team, which means the person who takes your first conversation is involved in your project, and also that availability matters so you should ask about timing early. They offer a consultation with Ryan Mach before you commit. We are connected with that business, which is disclosed on this page, and you should obtain other quotes and check insurance and references regardless of who recommends a firm to you.
Can I convert my basement into a self-contained unit for family?
It depends on the regulations before it depends on the design, and that order is what people get backwards. A self-contained suite is not a finished basement with a kitchenette added. Where it constitutes a second dwelling unit it engages municipal zoning, the building code and fire separation requirements, and feasibility is determined by unglamorous factors: ceiling height, window sizes and egress, a separate entrance, fire separation and parking. Requirements differ between Richmond Hill, Markham and other municipalities and they change, so confirm feasibility with your municipality and with a firm experienced in that municipality before paying for drawings. An unpermitted second unit creates problems with insurance, with a future sale and potentially with the municipality.
What should I ask a renovation contractor before hiring them?
Ask whether they pull permits as a matter of routine, which is the most important question and where a firm offering to avoid them has told you something important. Then: can I see current liability and workers' compensation certificates; who is licensed for plumbing, electrical and gas; what is in the quote and what is an allowance; how are changes priced and approved once work is underway; what is the payment schedule and the deposit; can I see two recent projects like mine and speak to those homeowners, including one where something went wrong; who is on site day to day; and what is your current availability. Get at least three written quotes with comparable scope and read the scope rather than the headline figure.
Do I need a permit for a renovation in Richmond Hill or Markham?
It depends on the work and the municipality. Structural changes, additions, many basement conversions and changes to plumbing, electrical or HVAC commonly require a permit, while finishes and cosmetic work commonly do not. Requirements differ between municipalities and they change, so confirm with the municipality or a qualified contractor rather than relying on any article. Use a firm that pulls permits as a matter of course, and keep every permit, drawing, invoice and final inspection record, because producing that file during a future sale resolves in minutes what otherwise takes weeks.
Should I renovate my current home or buy a different one?
It is a real comparison that people often fail to run, because moving carries costs that get left out: land transfer tax, legal fees, commission on the sale, the move itself, and the gap between what the current home sells for and what a larger one costs. Set against a renovation budget, the two can be closer than expected and sometimes the comparison points toward staying. Renovating to stay also removes the main weakness of pre-sale renovation, which is choosing finishes for a stranger. Have the real estate conversation and get a renovation consultation before committing to either path.
Why does a real estate team recommend a renovation firm?
Because it is the question clients ask most often after a purchase, and handing someone a list is less useful than naming a firm and explaining how to judge it. Purpose Built Designs is a business Kirby Chan and Co. Real Estate Team is connected with, which is disclosed on this page so readers can weigh the recommendation accordingly. The team receives no fee from a homeowner for an introduction. A real estate team is not qualified to assess structural design, waterproofing or code compliance and does not supervise anyone's work, so the homeowner's contract is with the renovation firm and verification of insurance, references and scope remains the homeowner's responsibility.
How do I get started on a renovation in York Region?
Decide first whether the renovation is to live in or to sell, because that changes every subsequent decision. If selling is anywhere in the plan, have the real estate conversation first so you know what level of finish the street supports and whether the work is warranted at all. Establish regulatory feasibility before paying for design, particularly for a lower level suite or anything structural. Then take a design consultation, get three written quotes with comparable scope, check insurance and references, and decide. Kirby Chan is a Broker with Kirby Chan and Co.
