I have always tried to design in Bay and even oriel windows in my house designs. Bay windows can often add a quite 'slot' to do the home work, read, write or draw, use a laptop, have breakfast and even admire, relatively undisturbed a sunrise or set-set, or admire your efforts in the garden. In a busy kitchen, where more people gather round these days to await or help with supper, a bay can provide the social spot, but still with work etc...more like the trad farmhouse kitchen many which seem to admire...(perhaps another blog). As Arthur Martin says in his 1909 book on house design 'The Small house', " Bay windows are convenient architectural devices for gaining extra space beyond the main walls of the house, being in themselves interesting features in the rooms. They not infrequently in small houses (Mr Martin describing in Edwardian Times houses more akin in area to executive homes now!) form the only comfortable corner for an easy chair or writing table..."

Chris Alexander et al. in  'A Pattern Language' make a plea for care in built in seat design for hardness and back height. A Pattern Language is indeed a wonderful guide to jolting a memory or spending time considering decision making, especially at design and detail level. Anyone considering designing and building should invest in a copy...wonderful and unique piece of work. Obviously another advantage of a bay window is that it captures sunlight and garden activity from three or more windows...so if your wondering whose car is pulling up or what the kids are up to!

Oriels are harder to make work, structurally and thermally. Plainly as a cantilever the structure will penetrate the building so will require ingenious insulation solutions...Theses are not impossible, but need careful exploration. Of course a solution is to build one on top of a ground floor bay or support from the garden...all to taste I guess (and the budget). A favourite device of mine is to extend outwards an oriel from a standard landing to create a hobby or work place which is very much part of the home's activities.
