What this preset is for
Class O PDR or full planning conversion. BCIS conversion rate is roughly 70 to 80 percent of new build.
BCIS conversion rate
- BCIS conversion £/sqm typically runs 70 to 80 percent of new build, but heavily condition-dependent.
- £1,750 to £2,000/sqm is a working London band; £1,500 to £1,750/sqm elsewhere.
Prior-approval costs
- Class MA prior approval: noise, contamination, flood risk, transport, daylight.
- Daylight (BRE 209) often kills schemes pre-residual. Always run a Mott or comparable study before bidding.
