Who we are

Our Story

LouMil Garden Buildings is a family-run business built on craftsmanship, honesty and straight-forward service. We started LouMil because we kept seeing the same problem in our industry — buyers being passed between salespeople, hit with hidden costs, and left with garden buildings that looked good in a brochure but failed within a few winters.

We do things differently. Every project is handled directly by our own small, committed team — no salesmen, no commission-driven quotes, no big-company nonsense. The person who designs your build is the person who oversees it being built.

We build each structure to proper standards using timber frames, EPDM rubber roofing and high-quality cladding and joinery throughout, with insulation, electrics and flooring available to your specification. Every garden room is treated as a permanent building — not a glorified shed — which is why we back every structure with a 10-year structural & roof guarantee.

Based in the West Midlands and installing nationwide across the UK, we keep our schedule deliberately tight so each project gets the time and attention it deserves.
