Home extensions

Built on Ultraframe systems

Every extension is structurally designed for your specific postcode and pre-approved against building regulations before work starts. Roofs range from full glass through to a 100% solid tiled finish with up to 10% roof glazing for light — your call, not a standard package.

Conservatory roof replacements

Two ways to fix a cold conservatory

If your conservatory is too hot in summer and too cold to sit in come October, the roof is almost always why. We replace it with one of two Ultraframe systems rather than patching the original.

Ultraroof — solid tiled roof

Marketed as the lightest and strongest tiled conservatory roof on the market — a fully insulated structural beam and panels mean it never needs a tie bar, and the inside gets a proper plastered, vaulted ceiling instead of a plastic liner.

Livinroof — hybrid solid & glass

A mix of solid insulated panels and glazed roof windows, so you keep a bright room without losing the heat retention of a solid roof. Prefabricated off-site, so most replacements are done within a matter of days.

A different build method

hup! modular extensions

hup! is Ultraframe's factory-made extension system — base, roof and wall panels are built off-site to the millimetre, then assembled on your foundations rather than built up brick by brick. There's no architect or independent structural calculations to arrange; it's project-managed for you by a trained hup! builder.

speedAround 5x faster to build, watertight in 2–3 days
u-values0.12–0.17 W/m²K — roughly 5x more efficient than the average UK home
walls~68% stronger than brick, ~60% less carbon to manufacture
roofsFlat, pitched, lantern or vaulted — four options
