Site Specific S106/Affordable Housing Economic Viability Appraisals

Flexton Developments


AspinallVerdi advised Flexton developments on a Economic Viability Assessment as part of a planning application for a site on Church Street, Slough. The proposed development is

  • Demolition of exiting building
  • Development of 41 new homes
  • 2 Retail units on the ground floor

Services Provided

AspinallVerdi provided the following services: 

  • Completed in depth market assessment from online sources and local agents.
  • Established robust assumptions to be applied in the development appraisal including, build costs and land value.
  • Built an evidence base to account for the impact Crossrail has had on both property prices and land values in the area.
  • Used Argus Developer to run a number of appraisals to understand the level of affordable housing the scheme could provide.


Our study provided the developer with evidence to support a reduced amount of affordable housing provision based on viability issues. The final report was to be submitted as part of the developers planning application.
