Multiplex Housing Modules

Each floor of our multiplex unit is designed as a standalone modular “box,” allowing you to mix, match, and stack them like LEGO blocks. Whether you’re creating a two-bedroom starter home or a spacious four-bedroom family unit, you can assemble your dream layout by combining these beautifully crafted modules. This innovative system not only speeds up construction but also gives you the freedom to customize your home to fit your lifestyle, your lot, and your vision.

Laneway Homes

Each floor of our two-storey laneway home is built as a modular “box,” designed for flexible assembly and fast construction. Whether you want extra living space or a private bedroom, the layout adapts to your needs. With smart design and a compact footprint, this home brings full-size living to even the smallest urban lots—efficient, customizable, and beautifully crafted.

How it works

  • 1. Project Planning and Feasibility Analysis

    We start by assessing the site, zoning, and budget. Whether it’s a multiplex infill or a full development site, we help clients evaluate land use, development potential, and required permits.

  • 2. Design & Engineering

    Our design team collaborates with clients to create customized or standardized modular plans. We prepare architectural drawings, structural engineering, and code compliance to meet local regulations.

  • 3. Permitting & Pre-Construction

    We coordinate development and building permit applications with the municipality, while preparing the site (grading, servicing, and foundation work) in parallel with off-site modular production.

  • 4. Off-Site Modular Fabrication

    Completed modules are transported to the site, craned into position, and joined together. We connect utilities, seal the structure, and complete exterior finishes and site landscaping.

  • 5. Delivery & Installation

    Our team performs final inspections, quality checks, and touch-ups before handing over the keys. We assist with occupancy permits and ensure every unit is move-in ready.

  • 6. Final Touches & Occupancy
