Frequently Asked Questions
Everything homeowners ask before starting their extension
Question 1: How long does a home extension usually take?
Most single-storey extensions take 8–12 weeks, depending on size, design, and weather. We provide a clear schedule before work begins so you always know what’s happening.
Question 2: Do I need planning permission for my extension?
Not always. Many extensions fall under Permitted Development, but we check everything for you. If planning is required, we handle the full application process.
Question 3: How much will my extension cost?
Costs vary depending on size, materials, and interior choices. Once we understand your design, we provide a detailed written quotation with no hidden extras.
Question 4: Will I need to move out during the build?
In most cases, no. We work in stages to keep disruption to a minimum. Only major structural projects may require temporary relocation for safety.
Question 5: How soon can you start my project?
Start dates depend on our current schedule, but we can usually begin within 4–8 weeks after finalising drawings, planning, and materials.
Question :6 Will I get a detailed breakdown of costs?
Yes — every client receives a full itemised quotation, including materials, labour, structural work, electrics, plumbing, and any optional upgrades.
Question 7: Can you help with the design and drawings
Definitely. We offer in-house planning and architectural drawings, including 3D visuals, so you can see exactly what your extension will look like
Question 10: How disruptive is the build process?
We work cleanly, safely, and keep disruption to a minimum. You’ll always know what’s happening thanks to clear daily communication from our team.
Question 11: What happens if unexpected issues come up?
If we uncover anything unforeseen (like old pipework or structural issues), we explain the situation clearly and agree on the solution before any extra work is done.
Question 12: Do you take care of building regulations?
Yes — we handle everything, including liaising with building control, scheduling inspections, and ensuring your extension is fully compliant.
