From memory, B1 requires an appropriate means of escape in case of a fire. Escape via a window is the general guidance on compliance (2 storey building), but Building Control will take other measures into account.

So as to avoid overlooking, the windows are at approx 2m. The house it set back 40m+ from the road and with no space for a fire engine to turn round, we went with a fire suppression system (Quantum Fog or similar).

Beds 3&4 have velux windows (north facing) in addition to the glass running the length of the split in the roof which faces south.

Evening all, Have spent a year researching the project, often ending up on this site, and own the obligatory Housebuilder's Bible: No. 12. Plans approved for a 4-bed home in our garden, pics attached: 15m x 8m with main 15m side facing south, half the footprint is double height. Looking at SIPs for wall/roof with render onto carrier boards. Glass panels where the roof splits provide light into the upstairs rooms. Small matter of approx. 300sqm permeable drive/parking areas, double garages for existing and new house etc. etc. Prospective builders have suggested that we sort out the build method and window supplier, then they'll come onboard to organise groundworks and all the trades. Keen to understand in practical terms (who doesn't love a spreadsheet!) the merits of living with 142mm vs 172mm SIPs, dbl vs triple glazing and how not to end up with a greenhouse.
