We specialise in chartered surveying on dense urban sites where rooftop and upward extension schemes are most common. The practice is RICS regulated with over 30 years of combined residential extension and rooftop experience. A free initial assessment covers feasibility and the most likely planning route on a specific site.


On rooftop additions to post-war estates and mansion blocks around Uxbridge town centre, Hayes, Yiewsley, and Cowley, the existing occupants liaison role becomes central. We make initial contact with each leaseholder below the proposed units, prepare Schedules of Condition for the flats directly below, and act as the named point of contact through construction. Daylight and sunlight reports typically accompany the planning submission given the impact of new height on neighbouring properties.
Airspace work in Hillingdon typically sits alongside daylight and sunlight, rights of light, and party wall workstreams on the same scheme. The same surveyor stays on the project from instruction to handover.
Where airspace work is feasible, the planning route depends on building type and proposed height. Many of Hillingdon's detached and semi-detached houses qualify for permitted development with prior approval, which avoids a full planning application. Rooftop additions to blocks of flats almost always need a full application. Specialist party wall services usually run alongside the airspace work itself.
