Orpington: rear extension delivered via PD checks

The brief

Open up the kitchen and dining area with a rear extension.

PD question answered

Do rear extensions need planning permission?
Not always—many qualify under PD if depth, height, and boundary rules are met.

Constraints

• Keep depth within PD thresholds
• Limit eaves and overall height
• Reduce neighbour impact

What we did

• Set depth to stay within PD limits
• Used a simple roof form to control height
• Produced clean drawings for compliance evidence

Outcome

Extra living space delivered quickly, without a full planning route.
