As seen on REW
One lot, a multigenerational multiplex.
Louis Nguyen of Costar shows how one lot becomes a multiplex where several generations of a family can live together.
Read Costar Construction: a family building family homes. by Zak Khan (July 30, 2026). It covers details like a main-floor bedroom so grandparents can skip the stairs, and keeping washing machines off the walls two homes share.
Louis Nguyen, Costar's Director of Sales, explains in 5 minutes 40 seconds what a multiplex is: three to six homes on one lot. He walks through the We Killarney six-plex, which puts a one-bedroom home with no stairs on the ground floor for a parent or grandparent. He also describes how a homeowner and Costar can share a project as partners, why Costar picks materials that are easy to maintain, and the 2024 Georgie Award.

How we build
Five stages, from first sketch to the inspections after handover.
Stage 01: Design & Planning
- 01
Design & Planning
In our first meeting you'll get a chance to interview us, and we'll get a chance to find out what your vision is. If you haven't decided on a site for your home, we can help you with an inspection and offer advice on suitability. If you have a designer or architect, we engage with them from the beginning of the drawings to ensure building feasibility of the home design. We can also recommend top design & architectural firms that we have successful relationships with.
- 02
Pre-construction
Costar and client will discuss the budget and agree on a cost plus arrangement for transparency. We will also discuss specification options, set a budget, and sign a written contract. Costar uses CoConstruct (of Buildertrend) software for tracking progress and expenses. Final drawings are submitted for permits and approvals, and any issues are resolved before setting building start dates and schedules.
- 03
Construction
During site preparation, we will excavate and pour footings and foundation walls. We will build floor joists, frame and sheath the exterior, and order windows and doors. The client will review details such as flooring, cabinets, electrical, lighting, plumbing, HVAC, media control, and alarms. Costar supervises the crew and subtrades to ensure quality standards are met, and conducts rough-ins for plumbing and heating, as well as city inspections. The client may visit the site regularly. Ask your Costar consultant to confirm in writing the insurance and WorkSafeBC coverage that apply to your project. Regular updates on progress will be provided to the client, who can voice any concerns.
- 04
Handover
Upon completion of the home, the site will be cleaned and any outstanding issues resolved. A joint pre-occupancy inspection will be conducted, and the client will receive an orientation on the home's features and maintenance guidelines for the home warranty that applies to the project. The client will receive the keys and a project binder containing manuals, warranties, and a list of contacts for tradespeople and appliances installed in the home, and Costar will sign off.
- 05
Warranty
The company will conduct inspections at 3, 6, and 12 months to ensure internal and external systems are functioning correctly. Any necessary fixes will be addressed within a few days. We want to help new owners make full use of the home warranty that applies to their home.

The Costar team was professional, friendly, and knowledgeable. They were good partners in our home renovation project, providing problem solving expertise and offering advice along the way.
I had the pleasure of working with Costar Construction recently, and I can’t express how impressed I am with the entire team, especially Louis. From the start, they made everything so easy and stress-free. Louis was an absolute joy to work with—always professional, attentive to even the smallest details, and super accommodating. He genuinely cared about ensuring that all built, all little details was done properly with care. The construction quality was top-notch. You can tell that Costar takes pride in their craftsmanship, and they don’t cut corners. They delivered my renovation on time, with everything done as promised, and went above and beyond my expectations. Very happy that I chose them for renovating our home. If you're looking for a construction team that combines skill, dedication, and an incredible work ethic, Costar Construction is the one! I highly recommend them and will definitely be working with them again in the future. Already planning to potentially build a laneway home, but that's for sometime in the future. Thank you, Louis and the team!
I recently got Costar to renovate my parents condo, and I couldn't be happier with the results! Our site manager Jackson was professional, on time, and always kept me informed throughout the entire process. Their team paid great attention to detail, and the quality of their work is amazing. Def recommend and will definitely work with them again in the future!
We worked with Costa Construction on an interior photography project and they were amazing! Super professional, detail-oriented, and the quality of their home builds is top-notch. You can tell they put a lot of care into their work. If you're looking for a great team to build or buy a house from, we definitely recommend Costa Construction!
I have enjoyed working and collaborating with Costar Constriction Inc. on the projects we worked on together. Louis and his team are not only great contractors but are amazing communicators as well. They are always looking out for the best interest of the clients and are actively listening to their concerns. Louis and his team are also open to collaborating with the designers to find excellent solutions for the client during the construction process. I would refer Costar Construction Inc. to anyone interested in their personal home renovation and/or tenant improvement for any business. I would be happy to work on more projects together with Costar in the near future.

Questions
Frequently asked questions about Costar Construction
What does Costar Construction build?
Costar Construction is a Vancouver construction management company. Its work covers multiplexes, custom homes, laneway homes and legal suites, kitchen and bathroom renovations, and commercial tenant improvements for wellness and beauty, healthcare, hospitality, office and retail, and childcare spaces. The office is at 104 - 338 W 8th Ave, Vancouver, and the first one-hour project consultation costs nothing.
Where does Costar work?
Costar lists eight serviced areas: Vancouver, Richmond, Burnaby, Coquitlam, New Westminster, North Vancouver, West Vancouver and Port Moody. Its laneway page says laneway homes are available in Vancouver, Burnaby and New Westminster. The office is at 104 - 338 W 8th Ave, Vancouver. Rules differ in each city, and every city page on this site lists the sources it relies on.
What is a multiplex?
Costar's multiplex page explains that a multiplex is a small-scale townhouse project on a single lot. The page says the cost of the land is shared over more homes and the units are smaller, so they cost less than single-detached homes or duplexes. Multiplex is the first of the six services Costar lists on its services page.
Can I check whether my lot suits a multiplex before I call?
Yes. The multiplex check on this site takes a Metro Vancouver address and returns a first set of numbers for that lot: how many homes the zoning allows, a first figure for the build cost, what the homes could sell for based on nearby sales, and what is left. The calculator is made by VanPlex. It is free, and it asks for your name, email and phone before it shows the numbers. Treat the result as a first check, and bring it to the free consultation.
What happens in a consultation, and does it cost anything?
Costar offers a one-hour project consultation at no cost. It takes place at your property or at the Costar office, 104 - 338 W 8th Ave, Vancouver. After you send the booking form, the Costar team sets a date and time with you by email or phone.
What are the stages of a Costar project?
Costar's process page describes five stages: design and planning, pre-construction, construction, handover and warranty. Design and planning starts with a first meeting where you interview the team. Pre-construction covers the budget, the specifications, a written contract and the permit drawings. Construction covers site preparation, the foundation, framing, the trades and city inspections. At handover the site is cleaned, you and the team inspect the home together, and you receive the keys and a project binder. In the warranty stage, the process page says the team inspects at 3, 6 and 12 months.
How is the price set?
According to Costar's process page, you and the team discuss the budget and agree on a cost plus arrangement, and then sign a written contract. A cost plus arrangement generally means you pay the actual cost of materials and trades plus an agreed amount for the builder. Ask your consultant for the exact terms on your project. The process page also says Costar uses CoConstruct software, from Buildertrend, to track progress and expenses.
Has Costar won an award or joined a builders' association?
Costar Construction Inc. won the 2024 Georgie Award for Best Multiplex Home, for the project It Takes Two, according to the 2024 winners list from the Canadian Home Builders' Association of BC. Costar is also listed in the member directory of the Homebuilders Association Vancouver (HAVAN).
