Airspace & Upward Extension Development

The most valuable land in London may be the air above your building. Adding storeys — under Class AA permitted development or full planning — creates new floorspace on land you already own. We assess it, consent and build it.
Structural and planning feasibility checked first
Designed and built above occupied space by one team
Class AA and full-planning routes both covered

ACCREDITED & CERTIFIED

Trusted by Leading Businesses

Not every roof can carry a storey.
What your feasibility study covers
01 — Which buildings qualify
Class AA rights depend on the building's age, height and type, and the structure has to take the load. We check both — planning and engineering — before anyone spends on design.
New floorspace, no land bought.
02 — The value case
Airspace development creates units or space where the land cost is already sunk — which is why rooftop schemes rank among the best value-per-consent moves in London. The appraisal shows what your roof is worth with consent, against real comparables.
Built above a building in use.
03 — Delivery
Craning, access, weathering-in and residents below — rooftop construction is a logistics discipline of its own. One team runs consent and construction, so the scheme that gets approved is the scheme that gets built.
