Do I need an architect for my project?
NO. Our qualified architectural technicians can handle all loft conversion projects at a fraction of traditional architect costs while maintaining professional standards and regulatory compliance for any type of conversion.
Do I need planning permission for a loft conversion?
Many planning applications aren’t needed as most loft conversion projects fall under Permitted Development rights. We assess your specific situation and advise on requirements during our initial survey, whether you’re planning a loft conversion or considering extension or conversion options.
What if my project needs building regulations approval?
Every loft conversion requires regulation drawings. We prepare these and coordinate with your building control officer until sign-off.
What will my loft conversion cost?
Your loft conversion cost depends on the property size, type of conversion, and whether it needs council approval.
Can I combine my loft conversion with an extension?
Is my project covered by permitted development rights?
Is my project covered by permitted development rights?
Your neighbour can’t usually stop a compliant loft conversion. If work affects a shared wall, you must serve a Party Wall Notice under the Party Wall etc. Act 1996. If they dissent, surveyors agree a Party Wall Award this doesn’t block your project but ensures it’s carried out legally and safely.
