Frequently Asked Questions
Will my extension match the existing house?
Yes, that's the goal. We aim for a smooth visual connection between old and new, including brick or render, roofline, windows, and internal finishes. The extension should read as part of the property, not bolted on, so the design and material choices are agreed with you before we start on site.
How long does a home extension take?
A single storey extension typically takes 3-4 months on site once work begins, with a two storey or more complex build closer to 4-6 months. The design, planning permission, and building regulations process adds time on top of that, which we'll walk you through before any spades go in the ground.
Are you based in Desborough?
