36‑Unit Townhouse
Cohesive Mechanical delivered high-efficiency plumbing and HVAC systems for nine townhouse buildings, helping Tsawwassen First Nation create durable, energy-smart homes for its members.
Tsawwassen First Nation - 36‑Unit Townhouse
Overview
Cohesive Mechanical partnered with Tsawwassen First Nation on its 36-unit member housing project, creating safe, affordable homes on treaty lands. The development includes nine two-story townhouse buildings and features new underground utilities, storm, sanitary, and potable water systems to support long-term growth in the community.
Key Challenges
Coordinated phasing – The mechanical scope needed to serve nine separate buildings in a phased construction plan.
Coastal resilience – Equipment had to withstand a marine environment and supply-chain delays while meeting environmental requirements.
Integrated infrastructure – New water, sewer, and storm systems required anti-corrosion protection for long-term reliability.
Energy and affordability – BC Housing’s standards demanded high-efficiency systems to minimize operating costs.
Our Solution
Cohesive Mechanical engineered and installed:
High-efficiency heat pumps providing each townhouse with year-round heating and cooling.
Robust plumbing systems integrated with site utilities and stormwater management.
Central control systems that allow TFN staff to monitor and adjust energy use across multiple buildings.
Phased installation strategies that kept work ahead of framing and mitigated delays.
Results
Efficient, reliable systems – The new mechanical infrastructure supports comfortable, safe housing while meeting BC Housing standards for low‑income, non‑market projects.
Reduced energy costs – High‑efficiency heat pumps and HRVs lower operating costs for TFN members compared with electric resistance heating.
Future‑proof design – Centralized control and quality equipment minimize maintenance and allow easy upgrades. Mechanical layouts were designed to accommodate additional future phases.
Conclusion
The TFN 36‑unit townhouse development represents a significant investment in member‑focused housing. By blending civil infrastructure upgrades with sustainable mechanical design, Cohesive Mechanical helped the Tsawwassen First Nation lay the groundwork for comfortable, long‑term homes. The project provides 36 new family townhouses and reinforces TFN’s commitment to bringing members back to their ancestral lands.
