Multiplex Homes

New density rules allow more units on your lot, but finding reliable partners who understand the process is your biggest concern.

You own valuable property and know new density rules allow more housing options, but you've heard stories about cost overruns and unreliable builders. Most established homeowners ask: "What's the best use of my lot, and how do I avoid costly mistakes?" Theorem provides transparent cost estimates and direct leadership access throughout your project. We eliminate surprises while keeping you informed and in control.

Create multi-unit housing that adapts to your family's long-term goals.

Your single-family lot likely qualifies for additional housing units under current zoning rules. Most established homeowners explore multiplex development for three reasons: creating housing for family members while maintaining independence, increasing property value, or generating rental income.

The key question isn't whether your lot qualifies, most properties in Vancouver, Burnaby, and New Westminster now do. The real considerations are: What configuration serves your family's long-term goals? How do you navigate approvals efficiently? What financing works best?

Theorem handles feasibility analysis, architectural design, municipal approvals, and construction management as a single point of contact. Whether you're planning multi-generational living, building equity for your children's future, or creating retirement income, multiplex development transforms your property into a flexible asset that adapts to your family's changing needs.
