Frequently Asked Questions
Everything you need to know about our design and build process.
A typical single-storey extension usually takes 12-16 weeks to build. However, the complete process—including architectural design, planning permission (approx. 8 weeks), technical drawings, and party wall agreements—generally spans 6-9 months from initial consultation to final completion.
Yes, we are a full-service design and build company. Our in-house architectural team manages the entire planning application process with your local council and ensures full compliance with UK Building Regulations, handling all structural calculations and inspections on your behalf.
We pride ourselves on transparency. Our fixed-price construction quote covers every aspect of the build: site setup, demolition, structural works, roofing, plumbing, electrics, plastering, and internal finishes. We itemize everything upfront so there are no hidden costs or surprise extras.
Absolutely. We hold £10 million Employers' Liability and £5 million Public Liability insurance. We are accredited members of the Federation of Master Builders (FMB) and TrustMark, and all our structural work is backed by a comprehensive 10-year warranty for your complete peace of mind.
For most extensions and loft conversions, yes. We install sealed dust screens and temporary kitchen facilities to minimize disruption to your daily life. However, for full-house renovations or major structural alterations, we generally recommend vacating the property to ensure safety and speed up the project timeline.
We serve clients across Greater London and the Home Counties. Our core areas include Chelsea, Fulham, Islington, Wandsworth, and Richmond, as well as projects in Surrey, Hertfordshire, and Essex. Contact our team to check if we cover your specific postcode.
