Why choose beam and block for an extension?
On an extension the new floor has to line up with the existing house, often over ground that has been disturbed by drains, old foundations or garden planting. A suspended beam and block floor deals with all of that neatly:
- No large volume of hardcore to import, compact and blind.
- It can span over drainage runs without loading the pipes.
- Where trees or clay soils are involved, a suspended floor is often required anyway.
- The level of the beams is set by the walls, so matching the existing floor is straightforward.
Keeping the existing house ventilated
If your house already has a suspended floor, the extension can block the air bricks that keep it dry. The usual answer is to carry the ventilation through the new floor void with ducts or vents, so both floors stay ventilated. Flag this up when you send your plans and we’ll allow for it in the layout.
Small floors, done properly
Even a small kitchen extension needs the beams set out correctly: the right spacing, bearing on the walls, and doubled beams under any partitions or heavy loads. You get a proper layout drawing and calculations for Building Control, however small the floor.
What we need
Your extension plans or a sketch with internal dimensions, the site postcode, and a note of any access issues for the delivery lorry. Photos of the side access are useful on tight sites.
