Find your build

Start with what you want the lot to do

The right project depends on your plans for the property. Here is where each goal usually leads.

Live in one, rent the rest

Duplex with suites

Live in one half and rent its suite, the other half and its suite. Up to four homes on a standard lot.

Duplexes →

Build to sell

Triplex or multiplex

Three to six strata homes, each sold on its own title. Frontage and site area decide the count.

Multiplexes →

Keep your house

Laneway home

A detached home off the lane for rental income or family, while you stay in the house at the front.

Laneway homes →

Add a home, simply

Suite or garden suite

A self-contained home inside the house or in the rear yard, without redeveloping the lot.

Suites & ADUs →
After: a finished three-storey multi-unit home with grey and cedar cladding Before After

Our work

From an empty lot to finished homes

Every project we build, from a garden suite to a six-home multiplex, runs through the same team from start to finish: feasibility, architectural design, the permit file, interior design and construction. There are no handoffs between separate consultants, which is where most delays and surprise costs start.

Drag the divider: all the way right shows the empty lot, all the way left shows the finished build.

How it works

Six steps from lot check to keys

The City’s median permit time for new low-density homes was 20.0 weeks in August 2026. A complete, coordinated application is how you stay at or under it.

  1. 01

    Lot check & feasibility

    Zoning, frontage, site area, trees and servicing, checked against current rules before any design money is spent.

  2. 02

    Architectural design

    In-house design to your zone’s rules, with suites, layout and energy requirements planned from the first sketch.

  3. 03

    Permits

    Sewer and water connection permit first, then the development and building permit, with us as your representative.

  4. 04

    Interior design

    Finishes chosen while the permit is in review, so the two run in parallel rather than one after the other.

  5. 05

    Price & schedule in writing

    A quote that sets out what is included, and a construction schedule with a target move-in date.

  6. 06

    Construction

    Daily photo and video updates in a private client portal, inspections at each stage, then occupancy.

Had a great experience with T City Developments. The team was professional, helpful, and easy to work with throughout the process. They paid attention to the details, communicated well, and made sure everything was done properly. I’m very happy with the quality of their work and would definitely recommend T City Developments to anyone looking for a reliable and professional builder.

Client testimonial

After struggling to find a reliable builder for our duplex project, we found T-City, and they delivered beyond expectations. They helped us maximize our lot, managed all the permits, and finished on time with zero surprise costs. Highly recommend for multi-unit builds.

Raj S.Surrey, BC

Client testimonial

We hired T-City to build a laneway home on our property in Burnaby, and the process was smooth from start to finish. They handled permits, design, and construction with total transparency. The portal updates were a nice touch and gave us peace of mind.

Mike L.Burnaby, BC

Client testimonial

T-City built our dream home from the ground up, and the experience couldn't have been better. Tommy and Andrew were professional, organized, and genuinely cared about getting the details right.

Common questions

Questions, answered

Can I build a duplex on my lot in Vancouver?

Most former single-family lots in Vancouver are zoned R1-1, where a duplex is allowed outright on a site of at least 306 m² (3,294 sq ft) with 7.3 m (24 ft) of frontage. Each half can add a secondary suite. Send us the address and we will confirm what yours allows.

How many homes can I build on a Vancouver lot?

In R1-1, a multiplex can hold 3 or 4 homes on a 10.0 m lot of 306 m², 5 on a 13.4 m lot of 464 m², and 6 strata homes (or up to 8 secured rental) on a 15.1 m lot of 557 m². A duplex with suites reaches 4 homes.

How big can a laneway house be?

In Vancouver, the lesser of 0.25 times the site area or 186 m² (2,000 sq ft). That is about 1,000 sq ft on a 33 × 122 ft lot and about 1,525 sq ft on a 50 × 122 ft lot. A laneway house goes with a single detached house, not a duplex.

Can I add a suite or garden suite without redeveloping?

Usually, yes. A secondary suite goes inside the existing house, and a garden suite or laneway house is built in the rear yard. The main house stays as it is, and you can normally live in it throughout.

How long do permits take?

The City of Vancouver reported a median of 20.0 weeks for new low-density homes, including duplexes, and 15.6 weeks for standalone laneway houses in August 2026. Complete, well-coordinated applications move fastest.
