Commercial Design-Build & Tenant Improvement Services in Toronto & the GTA

At TH Design Build Inc., we manage every step of your commercial and multi-residential construction projects — from concept and planning to permits, build-out, and final walkthrough. We work with landlords, property managers, and business owners to prepare and upgrade office spaces, common areas, and suites for new tenants or residents. Whether it’s an office renovation, corridor refresh, or move-in readiness project, we deliver seamless, start-to-finish solutions tailored to your property needs.

Office & Tenant Build-Outs

Create customized workspaces for your business.
We transform empty or outdated suites into functional, branded environments — handling demising walls, space expansion, mechanical and electrical work, lighting, flooring, millwork, and finishes. From shell space to move-in ready, we deliver efficient, high-quality build-outs designed around your operations.

Landlord Suite Turnovers

Get suites lease-ready faster.
We help landlords and property managers prepare suites for new tenants — whether it’s a commercial office or multi-residential unit. Our services include suite splits, cosmetic remodeling, flooring, lighting, paint, and small repairs. We make vacant spaces functional, modern, and marketable, helping reduce downtime between tenants.

Elevate shared spaces for better appeal.
We renovate corridors, lobbies, party rooms, and washrooms in both office and apartment buildings to enhance overall property value and tenant satisfaction. This includes electrical, mechanical, lighting, flooring, and finish upgrades, giving every area a professional, refreshed look.
