Extension Costs Estimate v Real Life

andrewf75

1k/m2 would be shell only I'd have thought these days. 1.5k finished but still an estimate, depends on many factors.

But I'd say these things always go over budget

Location will make a big difference to the price.

And the cost doesn't just come down to your tastes. What is already there, how deep will the foundations need to go. What is going in this extension? Empty rooms, a new kitchen, new bathroom? Does a gas pipe need to be moved. Does the soil stack need to be moved. There are endless things that can and will jack up the price.

We built a much smaller extension that that and have renovated 1 house and renovating a second. If there is one thing I have learned is that it all costs more than you think it will. Every time.

Good luck!

1k/m2 or 1.5k is it including materials or just labour? Sorry for asking a stupid question.

The price I quoted was for everything !

The frame package cost 17K that included all the flooring, doors & windows, plasterboard, skirtings, stairs and insulation.

The extra 30 was for the build / erection cost, bricks, foundation slab, roofing.

I did the electrics, plumbing and stove installation myself and got it all signed off by building control first time
