Airspace Viability

Build cost per unit, disruption and the value you unlock

This book teaches you to appraise a specific building and know, before you are committed, whether adding homes above it actually stacks up. It explains the numbers that decide a scheme: gross development value, total development cost, profit measured two ways and the residual value of the airspace itself. You will learn where to find sold prices, rental evidence, build cost benchmarks and planning history for free, and how to value each new unit honestly, including the value added to what already exists and the free land illusion. The cost chapter covers the airspace construction premium, the professional team, safety, warranties, building control, levies and the cost of building above people who live there. The scheme is stress-tested for a cost overrun, lower sale values and a longer programme. A complete worked example runs the method from end to end, and the final chapter gives you a ten-minute screen and the legal questions it cannot answer. Next in this series: “Rights, Leaseholders and Permitted Development”.
