Can I extend my Poundbury home?

Potentially, but Poundbury properties have restrictive covenants from the Duchy of Cornwall that control external changes. You need Duchy approval in addition to planning permission or PD compliance. Contact us to discuss the feasibility — we have experience working with Duchy requirements.

Do standard PD rules apply in Poundbury?

Many Poundbury properties have had PD rights removed by condition on the original planning permission. Even where PD technically applies, the Duchy covenant may still prevent the work. Always check both the planning position and the covenant before starting design.
