Why should it be a problem? The walls are all cavity insulated (and assuming there is suitable insulation for the roof) with the radiators it should be lovely and warm.
My extension has three exposed walls and quite a bit of glass. Given that the rest of the house was built in 1902 the extension is the warmest part of the house!

Dingdongler, is yours just the standard cavity wall insulation, how big is it, and how many radiators. Was there any issue with the original central heating boiler (assuming it was gas) having the capacity to feed an extra couple of radiators.

Okay. The reason i ask is my sister had an extension, but she never uses it because its too cold in the winter. A typical room in a semi or terrace has only one, or two exposed walls. Extensions often have three.

I would guess your sisters is an older extension not built to this standard or she is just a typical woman.

likely that they have either cut the wall insulation or the floor insulation its possible to do if they are cutting corners, my extensions not even got all its insulation in it yet and has no rads and its still warm, even with one wall being all glass (21sq metres!)

The room gets warm very quick and they insulated correctly as i over watched it..also the Survayor made near 7 visits to inspect each stage...
this is the gap that was left for the insulation all teh way to the top..
The survayor made us dig a 1.7m foundation (cost me an additonal £800)...because of a tree that was i think near 20m away..today i noticed the tree has been cut out completely..
Pic of the tree that no longer exisits..

Nice big doors! i was thinking of a large door as nice as it looks decided against it..as a hole wall is lost then..
looking good..how much did it set you back?
you have a picture from the inside out to the garden with the doors open?
is that decking outside the door? if so i am thinking something similar..as the plan was to fully open the doors and the garden feels like an extention of the extention - if kept clean.. lol

Paul, it was built about 4 years ago of standard breeze block, cavity and brick construction. Size is about 18ft by 14ft and it is open plan to my kitchen which is 18ft by 16ft.
The extension has a big patio doors (couldn't afford bifolding ones at the time lol) of about 3m wide and 2m drop, two windows (one is 1mx1m and the other is 1mx2m). There are also two velux rooflights. As I said its always the warmest part of the house.
