Airspace Surveyor in Kingston upon Thames

An airspace development creates new homes by building above an existing roof. Kingston upon Thames sees rooftop schemes on mansion blocks and post-war estates around the town centre alongside upward extensions on the Edwardian and Victorian housing. Our role covers the existing residents below the development, the schedules of condition that record each flat before construction starts, and the day-to-day liaison through the build.

Airspace Surveying Work in Kingston upon Thames

Kingston upon Thames carries a varied residential mix unusual for its size. The town centre and the area around Norbiton and Berrylands carry mansion blocks and post-war and 1960s estates suited to rooftop schemes. Surbiton, New Malden, and Tolworth run heavily to Edwardian and Victorian terraces alongside 1930s semis, where upward extensions on individual homes are most common. The outer parts of the borough through Coombe, Hook, and Chessington carry more detached suburban housing. Conservation areas across Kingston town centre, Surbiton, and parts of New Malden limit airspace work on protected sites.

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 on the more complex schemes.

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

  • 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 Kingston upon Thames?

On rooftop additions to Kingston's mansion blocks and post-war estates around the town centre and Norbiton, the existing occupants liaison role is central. We make initial contact with each leaseholder below the proposed units, attend meetings to discuss concerns, prepare Schedules of Condition for the flats directly below the new units, and act as the named point of contact through construction. Day-to-day issues, scaffolding placement, deliveries, parking restrictions, access, get handled as they arise.

On homeowner-led upward extensions across the borough's Edwardian terraced areas and the outer suburbs, the focus shifts to the Party Wall etc. Act 1996, neighbour relations, and protection of the existing structure during construction. Party wall services are nearly always involved given the prevalence of shared structures across the terraced streets.

Airspace work in Kingston upon Thames 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.”

What protections do existing occupants have in a Kingston airspace scheme?

Leaseholders below an airspace development retain quiet enjoyment of their flats and protection from damage to their property. Those protections only translate into useful outcomes when supported by structured processes during the build. The Schedule of Condition records the property's state before any work begins, which gives both the developer and the occupant documented evidence to refer back to.

The named occupant liaison surveyor sits alongside that. Each leaseholder gets one named person who answers queries during construction, attends meetings on site or remotely, and escalates issues directly with the contractor. Planning sits with the Royal Borough of Kingston upon Thames, and rights of light assessments often run in parallel where new height affects surrounding properties.
