A1 Fire-Rated Fibre Cement Boards
We are Benjamin and Robin, two individuals who once faced the challenge of breaking into the property market as renters. Like many, we found that traditional homes were simply out of reach due to sky-high prices. After visiting numerous new build sites, we had an epiphany: Why not build our own home and gain the equity instead of buying a new build?
This moment of inspiration led to the birth of Maize Homes.

of Supplier
We’re not a merchant. We’re a developer who found a better product, validated it on our own builds, and made it available to the market.
We Build With It
These boards go into our own Hampshire builds. We know how they perform in the real world-not just on a spec sheet.
Developer Pricing
No big brand overheads passed on to you. Genuine developer pricing without needing to be a national housebuilder.
Real People
Talk directly to us. Straight answers on spec, lead times, and pricing- no call centres, no middle layers.
Flexible Supply
One pallet or a full programme. We work around your project schedule, not our logistics convenience.
