Why Metro Vancouver homeowners choose Theorem for laneway construction..
Most homeowners ask: "What will this cost, and how quickly can I start?"
The challenge is navigating Metro Vancouver's zoning and permits that delay projects for months.
Theorem solves this for laneway and multiplex homeowners. While larger builders assign junior coordinators, you work directly with our leadership from site evaluation through completion.
We eliminate surprise costs, permit delays, and poor communication. You receive detailed cost breakdowns upfront, regular updates, and direct access to decision-makers, not call centres.
Whether building a laneway for rental income, redeveloping into a multiplex for multi-generational living, or planning retirement revenue, we handle Vancouver, Burnaby, Coquitlam, and New Westminster permits while you focus on outcomes: quality homes generating income and increased property value.
Everything we handle so your laneway project stays on track and on budget.
Site Evaluation & Feasibility
We assess your property's zoning requirements, lot configuration, and utility access to determine build potential and realistic costs BEFORE you commit. This includes reviewing density allowances and municipal-specific requirements that affect your project timeline and budget.
Design & Permitting
Our team coordinates architects, engineers, and city submissions to secure building permits efficiently. We handle Vancouver, Burnaby, Coquitlam, and New Westminster permit processes while providing regular updates on approval status and any municipal feedback requiring design adjustments.
Budget Development & Pricing
After site evaluation provides your initial estimate, we deliver your detailed construction budget once architectural plans are complete. This comprehensive breakdown includes all hard costs, permit fees, and contingencies, giving you transparent pricing before construction begins. No surprises, no hidden fees.
Construction Management
You receive access to our project management software with live budget tracking, daily progress photos, and milestone updates. Monthly formal meetings keep you informed without overwhelming you with construction details, while we coordinate all trades and inspections.
Final Completion & Occupancy
We manage final inspections, occupancy permits, and warranty documentation to deliver a move-in ready laneway home. This includes coordinating utility connections and providing you with all documentation needed for rental or family occupancy.
