Project Clarifications

Questions & Answers

Frequently asked questions regarding this specific London project execution.

help_outline Was planning permission required for this Kensington villa transformation? expand_more

Yes. Because the property is located within a Royal Borough Conservation Area, full planning permission was obtained alongside formal Royal Borough of Kensington and Chelsea (RBKC) design sign-off.

help_outline How did you manage structural stability and neighbor noise during excavation? expand_more

We installed real-time telemetry vibration sensors on shared party walls and executed underpinning in strict 1-meter bay sequences under chartered structural engineer oversight.
