Airspace Surveyor in Harrow
Adding Storeys Above Harrow Buildings
Harrow is one of London's most suburban boroughs, with residential stock heavily dominated by 1930s semis and Edwardian terraces across Pinner, Stanmore, Kenton, North Harrow, South Harrow, Rayners Lane, and Hatch End. 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 Wealdstone and central Harrow, where mid-rise residential blocks suit rooftop schemes. The Harrow on the Hill conservation area carries protected stock where airspace work is severely limited.
We specialise in chartered surveying on dense urban sites where rooftop and upward extension schemes are most common, and the practice is RICS regulated with over 30 years of combined experience. Daylight and sunlight reports typically accompany the planning submission given the impact of new height on neighbouring properties.
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.
How do we handle airspace developments in Harrow?
Project type drives the scope. On homeowner-led upward extensions across Harrow'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 and mansion blocks around Wealdstone and central Harrow, 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 Harrow 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 outcomes do well-run airspace schemes achieve in Harrow?
A well-run airspace project in Harrow finishes on programme with no damage claims from the residents below or the adjoining owners, no late objections from neighbours, and any existing occupants who feel they were kept informed throughout the build. The Schedule of Condition is the single most useful protection because it removes most of the damage argument before it starts.
Planning sits with the London Borough of Harrow, which reviews airspace proposals on design, height, neighbour amenity, parking, and area character. The Harrow on the Hill conservation area and various smaller conservation zones across the borough add heritage considerations to some sites. A free initial assessment covers feasibility and the most likely planning route on a given site.
