“How long does an extension take?”

The short answer: it depends on the size and complexity of the build — but a straightforward rear extension can take as little as 10 days with our team and planning in place.

At Four Oaks Builders, we can complete projects up to 50% faster than many traditional building setups.

That speed doesn’t come from rushing the job.

It comes from having a hand-picked team of highly skilled tradespeople, each experienced in their own specialist trade, rather than relying on generalists to do a bit of everything.

A great bricklayer, plasterer, electrician, plumber or carpenter is faster and better because they’ve mastered their trade.

It also means we’re not constantly losing days waiting for independent trades to become available.

Justin manages the whole project closely, coordinating each stage so one trade follows another and the job keeps moving.

That gives you:

  • Better workmanship
  • Faster progress
  • Fewer delays
  • Better coordination
  • A consistently high standard

So yes — a straightforward rear extension can sometimes be completed in as little as 10 days, while larger or more complex projects will naturally take longer.

Faster doesn’t mean rushed. It means skilled, organised and properly managed.

P.S. We offer FIXED-PRICE quotes — so there are no nasty surprises later.
