I'm having a bit of a problem with the design of our new utility room/conservatory and the building regs. people and was wondering if anyone has any ideas.
We got the builders to extend the house up to the old garage and was planning to convert the garage into a conservatory/utility room. The design I was going to go for has the right and far walls with solid brick for 1/3 at the bottom and 2/3 toughened glass above. I was going to leave the left wall as it is because it's on the boundary of the property and the neighbours garage is about 40cm on the other side. Roofing was going to be just clear square walled plastic sheets.
It turns out that although conservatories don't need to be inspected the building has to have over 50% transparent external walls to count as a conservatory. If it doesn't meet that requirement then it appears that it has to be built with double skin walls, double glazing etc.
I could put windows along the wall facing my neighbours garage but that would look ugly and I suspect I might run foul of planning regs for putting windows which look onto the neighbours property (even if all the window faces is a brick wall). The only other thing I can think of is to bring the glass all the way down to near the floor but I don't particularly want to do that as I don't think it would look as good.
I've no idea what the regulations are trying to achieve, they seem pretty crazy to me as the room is unheated and is outside the main house walls etc. so there will be no heat loss through it. I was wondering if anyone has any experience of this, or any ideas how to meet the regs without dramatically changing the design?
