The cost range
The width of the published conversion range is a reminder that floor plate, core position, servicing and façade constraints dominate the appraisal.
Key count first
Two buildings on the same street can differ materially in efficiency. Fixing the key count from measured information matters more than refining an optimistic rate assumption.
Our read
Test the scheme against the alternative use before design work begins. If the office basis cannot absorb both conversion cost and programme risk, reaching that conclusion early is the valuable answer.
