approx cost of 1st floor extension

[fxceltic]

Hi, a few years ago we had a large amount of extension work done on our home including a lounge across the back of the house with a flat roof.

Now we want to put a small ensuite out of the back bedroom onto the flat roof, we made sure that the footings of the ground floor and the roof trusses would be sufficient to allow us to do this at a later date.

So, we want to build a timber frame, pitched roof ensuite, 2.4 x 3.4 metres, on the flat roof.

Can anyone give me an approximate idea of cost per sq/ metre for this type of thing, because the quote we have so far seems extremely high at nearly £3000 p/sq/m?

I would have thought £1000p/sq/m was nearer the mark for what is a quite small piece of work.

, because the quote we have so far

There's your problem. Get a couple more quotes. If they're all at the same level, then that will confirm that your first quote is the going rate in your area.

The smaller the area the bigger the sq/m price, particularly if it is kitchens or bathrooms.

However £3k p/m² seems excessive. Does this include finishes and suite etc?
