From Extensions
To Approvals That Last
Even when a proposal seems “Permitted,” councils still assess impact, design, and scale. Larger extensions, outbuildings, or rebuilds often sit on the edge of PD limits and need careful handling to stay compliant.
FormedLands helps homeowners and small developers navigate complex or borderline PD schemes through evidence-led planning, local policy insight, and clear design logic.

Why Many Large Home Applications Fail
Most refusals happen not because the design is poor but because proposals misread the limits of Class A–E Permitted Development rights.
Councils still test height, depth, and neighbour impact under GPDO 2015 and local design codes. Without a clear justification or measured drawings, applications are easily refused.
At FormedLands, we translate PD legislation and local plan policy into drawings and narratives that demonstrate compliance and design quality.
