Conservation Area Extension FAQs

Clear answers to the most common questions homeowners ask.

Can I extend my home in a conservation area?
Yes, extensions in conservation areas are possible but require careful design that respects the area's character. We specialise in creating sympathetic designs that satisfy planning officers while maximising your space.
Do I need planning permission for a conservation area extension?
Most extensions in conservation areas require planning permission as permitted development rights are often restricted. We handle all planning applications and pre-application discussions with the local authority.
How long does conservation area planning take?
Conservation area applications typically take 8-13 weeks for determination, longer than standard applications due to additional heritage consultations. We recommend pre-application advice to streamline the process.
What materials can I use in a conservation area?
Materials must typically match or complement the existing building and surrounding area. We source reclaimed bricks, traditional lime mortars, period-appropriate windows and heritage roofing materials.
Can I have a contemporary extension in a conservation area?
Yes, many conservation officers actually prefer high-quality contemporary designs that contrast respectfully with historic buildings, rather than pastiche replicas. We design both traditional and contemporary solutions.
What is your planning approval success rate?
We achieve over 95% approval rate for conservation area applications due to our thorough pre-application process, heritage expertise and established relationships with local planning authorities.
