Airspace Surveyor in Southwark

An airspace development creates new homes by building above an existing roof. In Southwark, the work concentrates on the borough’s extensive post-war estates, mansion blocks, and mixed-use buildings across the regeneration zones. 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.

Adding Storeys Above Southwark Buildings

Southwark's residential stock runs across some of London's most varied building types relevant to airspace work. The post-war estates across Walworth, Peckham, Camberwell, and Rotherhithe carry significant mid-rise residential blocks where rooftop schemes are most viable. The regeneration zones at Elephant and Castle and the Bankside area add mansion blocks and mixed-use buildings, while the older streets through Bermondsey, Borough, and parts of Camberwell carry conservation constraints that limit airspace work on many sites. The combination produces a mix of rooftop schemes on residential blocks, mansion block additions, and a smaller volume of upward extensions on individual homes.

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 experience. Schemes typically need rights of light assessments given the tight plot density and impact of new height on neighbouring residential windows.

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 our airspace service in Southwark cover?

On rooftop additions to Southwark's post-war 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, deliveries, parking restrictions, access, get handled as they arise.

On smaller homeowner-led upward extensions in the borough's less dense streets, the focus shifts to the Party Wall etc. Act 1996, neighbour relations, and protection of the existing structure during construction. Daylight and sunlight reports almost always form part of the planning submission given the borough's tight plot density.

Airspace work in Southwark 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 airspace developments affect existing residents in Southwark?

Residents below an airspace development carry the most direct impact: noise during working hours, disruption to access and parking, scaffolding obscuring windows, and concern about damage to their flats. In Southwark's dense streets and estate layouts these effects are particularly visible because neighbouring residential buildings sit so close to the site.

Strong liaison and a thorough Schedule of Condition deal with most of this before it starts. Residents get one named contact, the developer gets a structured process for concerns raised during the build, and the Schedule provides documented evidence if a damage claim arises later. Planning sits with the London Borough of Southwark, and a free initial assessment covers feasibility and the supporting workstreams on a specific site.
