Small Extension (3mx2m) Quotes

How much on average for a 3m x 2m extension on back of a terrace house, with a toilet.

I was quoted £55k approx in the SE, but for a 3mx2m with a toilet at the back of a terrace house seems quite high, especially when I have to provide the tiles for the flooring and toilet and basin.

Thoughts?

"Have you asked the builder for a breakdown of the costs involved? I know material costs have risen quite high, but that does seem a little high.

"Yes that is very, very high. A rough estimate for a job of that size would be £20,000. That would include all labour and materials required to finish the job."

"Typical costs you can expect to pay:
For a small (15m²) rear house extension, the cost is around £30,000 – £42,000. For a medium (30m²) rear house extension, the cost is around £40,000 – £56,000. For a large (50m²) rear house extension, the cost is around £100,000 – £140,000.

So yes, £55k seems very high, especially if everything isn't included"

"I do think the price for this is really expensive especially not supplying tiles toilet and basin, usually prices are charged at £4,500 to £6,500 per square meter depending on what your are getting, but for a 3m by 2m the price is high, would recommend getting more quotes to see the difference. If you have anymore information please send me a message"
