Airspace Surveyor in Sutton
Rooftop Schemes and Upward Extensions for Sutton
Sutton is one of London's most suburban boroughs, with residential stock dominated by 1930s semis and Edwardian terraces across Cheam, Carshalton, Wallington, Worcester Park, Belmont, and North Cheam. Upward extensions on individual homes are the most common airspace work, and many semi-detached and detached properties qualify for prior approval extensions under permitted development. Post-war and 1960s estates concentrate around Sutton town centre, Hackbridge, Beddington, and Rosehill, where mid-rise residential blocks suit rooftop schemes.
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. Airspace development advice covers feasibility and the planning route before any application is prepared.
Airspace Developments
As well as providing daylight, sunlight and rights of light advice, our role would be to make contact with the occupants of the existing building to establish any concerns regarding the development. We will work closely with the professional team to identify the initial questions and look at how these can be addressed.
It is our experience that maintaining the same point of contact for the duration of the project offers the existing occupants’ reassurance and continuity.
Services Provided
- Make initial contact with existing occupants.
- Attend meetings to discuss any concerns of the existing occupants.
- Recording Schedules of Condition of the flats below the proposed units.
- Act as a liaison between the developer and occupants throughout the project.
- Assist in resolving any issues that may arise such as car parking, site setup etc.
What does an airspace surveyor do in Sutton?
Project type drives the scope. On homeowner-led upward extensions across Sutton's 1930s semis and Edwardian terraces, the focus is on the Party Wall etc. Act 1996, neighbour relations, and protection of the existing structure during construction. Many semi-detached and detached properties qualify for prior approval extensions under permitted development, which changes the planning route but not the party wall obligations.
On rooftop additions to post-war estates around Sutton town centre, Hackbridge, and Rosehill, 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. Rights of light assessments are common where new height affects neighbouring residential windows.
Airspace work in Sutton 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.
Over the past four years, CHP have worked very successfully with us in their capacity as party wall surveyors. Through his calm, sensible approach and excellent communication skills James Crowley, in particular, gained the trust and confidence of the entire team and stakeholders. Looking forward to working with CHP again.”

How do you reduce risk on a Sutton airspace scheme?
Risk on a Sutton airspace scheme sits in two places: disputes with adjoining owners on homeowner-led upward extensions, and damage or occupant disputes on rooftop additions to residential blocks. A structured party wall process removes most of the first by serving notices correctly, agreeing Schedules of Condition with each adjoining owner, and producing an Award before work starts.
Occupant liaison and a named point of contact removes most of the second. Planning sits with the London Borough of Sutton, which reviews airspace proposals on design, height, neighbour amenity, parking, and area character. A free initial assessment covers feasibility and the most likely planning route on a given site, including whether permitted development with prior approval applies.
