What Doesn't Change

Six services. One way of working.

The site visit usually helps us identify the services your project needs. Across all six, we coordinate the design, supervise the work, and agree the fixed price for the defined scope before you sign.

1

One company coordinates your project.

The architect drawing it, the designer specifying it and the crews building it all work for the same firm. Our team coordinates the drawings and site requirements within the agreed scope.

2

Nothing starts until the number is agreed.

We price the defined scope as a fixed figure, itemized line by line. Review the contract terms for price adjustments, allowances, exclusions and changes.

3

The same coordinator stays with the job.

One person runs your project on site from first day to handover, and the portal carries the schedule, the selections and the progress photos so you can follow progress in one place.

4

Every selection is made in one building.

Cabinetry, tile, stone, hardware and fixtures are all at the design centre on Avenue Road. Review available samples with the team and confirm any additional selections or supplier visits needed.

5

We remain responsible for the work.

Review the handover documents and applicable coverage with us. We remain your point of contact for questions about the completed work.

6

We take on a limited number of projects.

A limited number of jobs gives each coordinator time for their site. We confirm whether a project fits our team and capacity before taking it on.

Before You Commit

What happens between your first email and a price.

Discuss the proposed next steps, any fees and the scope of each stage before proceeding.

  1. Step 1A short call

    An initial conversation about the work you have in mind and whether it fits the services we offer.

  2. Step 2The site visit

    We come to the house, measure, look at what we can see of the structure, and check the lot against current zoning before anyone draws anything.

  3. Step 3The scope document

    A written description of exactly what is and is not included, sent before any price. This gives everyone a shared understanding of the scope.

  4. Step 4The written plan

    The plan against that scope, walked through in person at the design centre. It stands on its own, and you are free to take it to another builder.

Not Sure Which One

Start from what you are trying to do.

Most people arrive knowing the outcome they want, not the name of the service. These are the situations we hear most, and where each one leads.

Still not sure, or sure it is two of them? Describe the house and what you want out of it, and we will tell you which of these fits, including when the answer is that you do not need us yet.

Areas We Serve

Where we build

We work throughout Toronto and the GTA. These are the neighbourhoods we know best, each with its own zoning quirks and committee history.

Can't find your neighbourhood?

We build across Toronto and the GTA. These are the ones we work in most, not the only ones we work in.

Frequently asked questions

Questions homeowners ask before they call

If the answer you need is not here, ask us on the call.

Which of these do I actually need?

Tell us the outcome and we will name the service. Roughly: an addition when the house is right but too small, a renovation when the space is there but not working, a laneway or garden suite when the land can carry a second dwelling, and a custom build when reworking what is standing costs more than replacing it. A site visit can help identify the scope. Confirm the visit arrangements and any fees before booking.

Can one project use more than one of these?

That is the normal case rather than the exception. An addition nearly always includes design and permits, and most renovations include some structural work. You get one contract and one price covering all of it, not a separate agreement per service.

Do you take on single rooms, or only whole houses?

Kitchens, bathrooms and basements are regularly done as projects in their own right. Beyond those it depends on what the work touches: anything structural, or anything needing a permit, has a floor below which we cannot run it properly. Ask us with the specifics and you will get a straight answer.

Can I hire you for the design and permit only, and build it elsewhere?

Yes. Design and permits is a service in its own right, and the approved drawing set is yours. It is also fine the other way around: if you already have drawings from an architect, we can drop design from the scope and price the build alone.

Renovate or tear down and rebuild? How do we decide?

Three things decide it: the condition of the existing foundation and framing, what the current zoning lets you build on that lot, and how much of the existing house you would genuinely keep. We look at all three on the site visit and show you both routes before you commit to either.

What happens if something changes once the work has started?

Changes should be documented with their effect on scope, cost and schedule before the affected work proceeds. Review the contract provisions for allowances, exclusions and unforeseen conditions.

Who is actually on site day to day?

Your project coordinator is your contact for the build. Confirm the site supervision and communication arrangements before work starts, including how any team changes will be handled.

What should I have ready before the first meeting?

Nothing at all is required. If you happen to have a survey, existing drawings, a status certificate, or a rough budget range in mind, they make the first conversation faster, but none of them are needed to book a visit.

Start here

Not sure which one you need?

Tell us what you want to change. We can discuss whether a renovation, addition, custom home or secondary dwelling suits your plans and which questions need a feasibility review.
