from pulling out our house sale to an extension

The extension is getting bigger as we speak!

I have no idea where £80-100k comes from either but I'll tell you right now that the builder is out of his tiny head if he thinks what you describe costs £30k. £1000 a metre does not exist anymore, has not for a long time, never included VAT and was based on square, basic, two storey new builds, not single storey extnsions with an exceptionally high proportion of new wall to gained space plus a large amount of knock through steelwork and renovation to the existing ground floor. You need something over 20 linear metres of footing to gain 30 metres of space. That isn't just lacking in economy of scale, it's backwards on the scale.

Imagine, could build a square shaped, 200sqm house with 40 linear metres of footings! They are never, never going to cost the same per square metre and your house incurs VAT on the work too.

Do not get sucked into ideas of cheap builders as you will end up half way into a project having spent what you thought was the full budget. Steer well clear.

Your post really belongs in the "In My Home" board as it doesn't relate to home buying, it relates to building.

The extension isn't increasing.... Maybe i didn't explain clear enough.

As the house currently stands, we are going to extend 3 metres out the back of the house, 8 metres across.

Alond the side of the property (ie. wraparound) we are extending 1.8m width, and 4 metres in length.

It started at 2.6, then 2.8, then 3 metres. It doesn't matter as you gain better value the larger it gets but you've ignored the main point. It is not going to cost £30k. Do not get sucked in, do not entertain that builder. You will be back on these boards with an incomplete building project and no money left.

"We currently have a 3 bed semi, with a driveway along the front and side of the house. What we are proposing is extending out 2.6metres all the way across the back, and 1.8m out, alongside the house (to allow enough soace to get a side gate to access the garden)"

Now using metric often confuses me.
If you build 1.8 meters out at the side you end up with 5.90551 FOOT
so less than 6 foot extension.
You would need to consider carefully what you would do with this extra 6 foot along the side of the property.
Now 9/10 feet would make a good downstairs shower room.
You only have a small rear garden so 6 meter rear extension would fill the rear garden.
I had built a side and rear extension a few years ago which went out about 9 feet out at the side and 20 feet at the rear and it cost about £80,000 in 2012.
Big job with the corner of the house removed and lots of steel work.
