Frequently Asked Questions
Do I need planning permission for a basement conversion?
Most basement conversions fall under permitted development rights and don't require planning permission. However, you'll always need Building Regulations approval. If excavating below existing foundations or changing external appearance, planning permission may be required. We handle all planning and building control submissions on your behalf.
How long does a basement conversion take?
Most basement conversions take 8-12 weeks to complete. The timeline depends on the scope of work, waterproofing requirements, and finishing specifications. We provide detailed project schedules and keep you informed throughout.
Will my basement be dry and damp-free?
Yes - we use industry-leading waterproofing systems including Cavity Drain Membrane (CDM) tanking to guarantee a dry, habitable space. All waterproofing work comes with comprehensive insurance-backed warranties.
