Home Addition Contractors in Coquitlam, BC
Room additions, second-storey additions, and garage conversions — real square footage added with engineering, permits, and construction handled end-to-end, in Coquitlam and across Greater Vancouver.
When the family outgrows the house but the lot, the street, and the schools are exactly right, an addition is how you stay. It's also the most regulation-heavy residential project there is: setbacks, lot coverage, and height limits decide what's even possible before design begins, and the structure has to be engineered to carry the new load. This is where additions go wrong with the wrong contractor — a design the city won't approve, or a build the existing foundation can't carry. Bouri Contracting starts every Coquitlam addition with the zoning reality check, so the plan you fall in love with is one that gets permitted and built.
We build additions of every kind across the Tri-Cities and Metro Vancouver — main-floor family room and kitchen extensions, primary suites over garages, full second storeys on post-war bungalows, and garage conversions into living space. And because an addition always touches the rest of the house — roof tie-ins, siding matches, flooring transitions — it pairs naturally with our home renovation services and full house renovations when the project grows.
Home Addition Services in Coquitlam
Room Additions
Main-floor extensions — family rooms, larger kitchens, dining space — with foundations, roof tie-ins, and seamless siding matches.
Second-Storey Additions
A full new floor on an existing footprint — the biggest square-footage gain available without touching the yard.
Primary Suite Additions
Bedroom, ensuite, and walk-in closet additions — over the garage or extending the main floor.
Garage Conversions
Existing garages converted into living space, offices, or suites — insulation, heating, flooring, and code compliance included.
Zoning & Engineering
Setback and lot-coverage review, structural engineering, and drawings — confirmed before design money is spent.
Seamless Integration
Rooflines, siding, windows, flooring, and trim matched so the addition reads as original to the house.
What Determines Home Addition Cost in Coquitlam
Addition budgets are driven by: type (a garage conversion reuses existing structure; a ground-floor extension needs foundations; a second storey needs the existing structure assessed and often reinforced), size and complexity of the new space, what goes inside it (a bedroom costs far less per square foot than an ensuite-equipped primary suite), engineering and permits (every addition needs structural drawings and municipal approval), and integration work (roof tie-ins and siding matches done properly). These factors hold across Coquitlam and all our Metro Vancouver projects.
Every Bouri addition quote is free, on-site, and itemized — and the zoning feasibility check comes first, so you never pay for a design the city won't approve.

Yes — every addition requires a building permit, structural drawings, and compliance with zoning rules like setbacks, lot coverage, and height limits, which differ between Coquitlam and other Metro Vancouver municipalities. Bouri Contracting runs the zoning feasibility check first and handles all engineering, drawings, permits, and inspections for you.
The decisive factors are the addition type (garage conversion, ground-floor extension, or second storey), its size, what goes inside it, engineering and permit requirements, and the roof and siding integration work. Bouri Contracting provides a free feasibility check and an itemized quote so you know the real cost of what your lot allows before committing.
Many can — but it depends on the existing foundation and framing, which a structural engineer must assess. Reinforcement is often possible where the structure falls short. Bouri Contracting arranges the structural assessment as part of the feasibility stage, before any design spending, so you get a clear yes, no, or "yes with reinforcement" up front.
When the location is right and the house is just too small, an addition usually wins: you avoid the heavy transaction costs of selling and rebuying in Metro Vancouver, keep your neighbourhood and school catchment, and add square footage that appraises. Bouri's itemized quote gives you the real number to weigh against the cost of moving.
Yes. Coquitlam is home base, but Bouri builds additions across Greater Vancouver, including Port Coquitlam, Port Moody, Burnaby, Vancouver, Richmond, North Vancouver, and West Vancouver. Call (604) 615-1756 or message us on WhatsApp for a free feasibility consultation.
