The unused loft and airspace above a building can be a valuable and often overlooked asset. Kingston Surveyors arranges an RICS Registered Valuer to assess the development value of loft space and rooftop airspace, giving freeholders, leaseholders and developers a Red Book figure to support a sale, lease or negotiation. We provide loft and airspace valuations across London, where permitted development and rooftop schemes are especially active, and nationwide.
A loft or airspace valuation establishes the market value of the right to develop the space above an existing building, whether for a loft conversion, additional flats or rooftop extensions. It weighs the potential uplift in value against build costs, planning prospects and any premium payable to the freeholder, producing a defensible figure for the transaction in hand.
Valuations are commonly required when a freeholder wants to sell airspace rights, when leaseholders or a residents’ company negotiate to acquire the roof space, when developers appraise a rooftop scheme, or where the value forms part of an enfranchisement or lease dispute. An independent RICS opinion helps all parties agree a fair price.
Our panel of RICS Registered Valuers understands development appraisal and the leasehold framework that governs airspace, so your instruction is matched to a valuer with the right expertise. Reports are accurate, Red Book-compliant and delivered to your timetable. Contact Kingston Surveyors for a free, no-obligation quote on a loft or airspace valuation.

Loft space and rooftop airspace derive their value from development potential: what could be built, what consent it would get, and what the completed space would be worth minus the cost of creating it (the residual method). The RICS Registered Valuers we arrange assess freehold airspace for sale or development appraisal, and leasehold loft space where a leaseholder wants to buy the demised roof void from the freeholder.
Freeholders selling airspace to developers under permitted development rights; leaseholders negotiating to purchase loft space before conversion; developers appraising rooftop schemes. Each needs a defensible figure for negotiation or tribunal. Related: loft structural design, Red Book valuations and valuation fees. Call 0204 579 8270.
