Airspace Surveyor in Hammersmith and Fulham
Rooftop Schemes and Upward Extensions for Hammersmith and Fulham
Hammersmith and Fulham carries a residential stock that splits across very different building types. The post-war and 1960s estates across White City, the southern parts of Fulham, and the Sands End area carry significant mid-rise residential blocks suited to rooftop schemes. The mansion blocks through Hammersmith, Brook Green, and parts of Fulham add another concentration of buildings where airspace work comes forward. The Victorian terraced streets across Fulham and parts of Hammersmith run more heavily to upward extensions and side-and-up additions on individual homes. Our work covers Hammersmith and Fulham from our London office.
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. Party wall services are nearly always involved given the borough's dense building pattern.

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 deliver airspace projects in Hammersmith and Fulham?
On rooftop additions to the borough's post-war estates and mansion blocks, 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 on narrow streets, deliveries, parking restrictions, access, and noise, get handled as they arise.
On homeowner-led upward extensions across Fulham and Hammersmith's terraced streets, the focus shifts to the Party Wall etc. Act 1996, neighbour relations, and protection of the existing structure during construction. Rights of light assessments are common given the tight plot density and impact of new height on neighbouring residential windows.
Airspace work in Hammersmith and Fulham 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 planning considerations apply to airspace schemes in Hammersmith and Fulham?
The London Borough of Hammersmith and Fulham reviews airspace proposals against design, height, neighbour amenity, parking, daylight and sunlight impact, and area character. The borough has substantial conservation areas across Fulham, Hammersmith, and Brook Green, plus listed buildings throughout. Many central sites are constrained by heritage considerations before any other planning issue comes into play.
Where airspace work is feasible, the planning route depends on building type and proposed height. Some upward extensions on detached and semi-detached houses can proceed under permitted development with prior approval. Rooftop additions to blocks of flats almost always need a full planning application. A free initial assessment covers feasibility and the most likely route on a specific site.
