15 Years of Building
Trust & Quality
TCM Building & Maintenance was founded on a simple principle: deliver the quality of work you'd want done on your own home. Based in Ilford, we serve homeowners and businesses across London and Hertfordshire with a full range of building and maintenance services.
Our team includes qualified architects, structural engineers, and specialist tradespeople — all under one roof. We manage your project from initial design through to final handover, so you never have to coordinate multiple contractors.
Loft Conversions That
Transform Your Home
A loft conversion is one of the most cost-effective ways to add space and value to your home — typically adding 20–25% to your property's value without losing garden space.
Commercial Fit-Outs &
Office Refurbishments
We understand that business downtime costs money. Our commercial team works around your schedule — including out-of-hours and weekend working — to deliver fit-outs and refurbishments that minimise disruption to your operations.
What Our Clients Say
