I think today that if someone was designing a house one would incorporate all the modern additions which have suddenly become fashionable such as double porches, doubleglazing and er patio windows, I think that these things are perhaps a development from, in the same way as this house is a development from the rooms and the flats we lived in in London so that the modern conceptions of the things I've mentioned could be incorporated as normal in the house certainly would be cheaper to incorporate them when building the house than adding them on.
