What Assembly does

Assembly (legal entity Assembly Corp., formerly R-Hauz Solutions Inc.) is a Toronto-based prefabricated mass timber construction company founded in 2019 by Leith Moore and co-founded by Michael Barker. The company designs, manufactures, and assembles modular wood buildings — mid-rise (4-6 storey) structures, laneway and garden suites, and 1-12 storey affordable housing — using Cross Laminated Timber (CLT), Glue Laminated Beams (Glulam), and Laminated Veneer Lumber (LVL) within a proprietary Design for Manufacturing and Assembly (DfMA) kit-of-parts system of five configurable components (decks and beams, load-bearing walls, facades, interior finishings, and technical installations). Building Information Modelling (BIM) in Revit with parametric design reportedly cuts design timelines by 60%, while factory-built panels reduce onsite material waste by 80% and onsite labor by 50% versus traditional construction. Assembly is currently transitioning from a Toronto-based project builder to a vertically integrated manufacturer, having acquired factory equipment and mentorship from Sweden's Lindbäcks Bygg (Group) in February 2025 with a planned operational manufacturing facility in 2026 targeting 960 units annually; until then, components are produced through manufacturing partner Fab Structure in Ripon, Quebec.

The company operates a hybrid go-to-market model. The direct-to-consumer motion targets property owners seeking laneway, garden, or mid-rise buildings, with a website property-assessment funnel ("Start Building") and a quote-based, fixed-price model covering the full entitlement-to-occupancy process. The institutional motion targets non-profit housing providers and municipal governments for rapid affordable-housing delivery, with named customers including St. Matthew's House, St. Clare's Multifaith Housing, WoodGreen Community Services, YMCA of Greater Toronto, Elizabeth Fry Society, Thunder Woman Healing Lodge, Region of Halton, and the Regional Municipality of York. Revenue is generated as one-time fixed-price construction contracts bundled with turnkey professional services (entitlements, utility connections, finishes, warranty). To date, the company has raised $4.5M CAD in seed funding (November 2020), a $130K NRC IRAP grant (2020), and a $3.57M round led by PaceZero Capital Partners (October 2025), and holds COR, HCRA, and CHBA Qualified Net Zero Builder certifications.

Core offering

Assembly designs, manufactures, and constructs prefabricated mass timber modular buildings using a Design for Manufacture and Assembly (DfMA) kit-of-parts system. The company delivers configured-to-order mid-rise residential buildings, laneway and garden suites, and 1-12 storey affordable housing projects for property owners, non-profit housing providers, and municipalities. Services span site assessment, entitlements, utility connections, onsite assembly, finishes, and warranty on a fixed-price turnkey basis.

Product overview

Assembly (formerly R-Hauz) offers a portfolio of prefabricated mass timber modular housing products designed for speed, affordability, and sustainability. The product line consists of three core building types: Mid-Rise Assembly (4-6 storey mass timber buildings for main streets and transit avenues), Laneway and Garden Suite Assembly (low-rise detached units compliant with Toronto bylaws), and Affordable Housing Assembly (1-12 storey rapid modular housing for municipalities and non-profits). These are complemented by specific suite models including the Elevation Model (1 bed, 15x20 ft), Superkül Model (2 bed, 20x26 ft with barrier-free option), and Forma Collection (expandable core design). All products use a DfMA kit-of-parts system with 5 basic components (decks/beams, load-bearing walls, facades, interior finishings, technical installations) that are prefabricated offsite and assembled onsite. The company is transitioning from a Toronto-based builder to a vertically integrated manufacturer with its own factory planned for 2026.

Expansion highlights5 records

Broad incumbents

• Bird Construction: Major Canadian general contractor with multi-billion revenue and broad multi-sector building capabilities. Competes with Assembly on large institutional and government building contracts in Canada, though lacks Assembly's specialized mass timber prefab focus.
• Wernick Group: UK-based modular building manufacturer with decades of experience producing offsite-built permanent and temporary buildings. Comparable industrialized construction capability, though broader portfolio including commercial and modular site offices.
• Plant Prefab: US-based prefabricated home and building manufacturer using sustainable materials and factory-built panels. Comparable product platform and DfMA philosophy; serves a broader set of custom and developer-led residential projects across the US.

Emerging players

• Boxabl: US-based factory-built housing manufacturer focused on rapidly deployable foldable panelized homes. Comparable in panelized prefab approach and focus on speed-to-occupancy, though serving single-family detached use cases.
• Tophat: UK modular housing manufacturer using panelized timber-frame systems for residential buildings. Comparable in panelized offsite construction for mid-rise residential, though primarily operating in the UK market.
• Cover (Cover Technologies): Prefabricated backyard home (ADU) maker with software-driven customization and factory manufacturing. Comparable to Assembly's laneway/garden suite line in product category and DfMA-enabled customization.

Direct peers
