Croydon's relatively low conservation area coverage means most Edwardian terraces can proceed via permitted development for loft conversions. The PD volume allowance for a terrace is 40m³ — the L-shape configuration here added 38.4m³, within the limit.
The rear dormer was set at 200mm from each party wall — the minimum setback under PD rules. The side dormer extended to the hip, creating an L-shape that maximised the usable floor area without requiring a full hip-to-gable conversion (which would take the volume above 40m³).
Croydon's LDC team processed the certificate in 5 weeks. The certificate was required because the client's solicitor needed evidence of lawfulness for a simultaneous remortgage — the certificate provided the legal certainty the lender's surveyor required.
We also prepared the building regulations package concurrently, using fast-track BCO submission through Croydon's approved inspector scheme. Both the LDC and building regs approvals were in hand within 7 weeks of instruction.
