The vast majority of our built environment that is worth protecting was built before the Town and Country Planning Act 1947, when there was much less control on what could be done. Also, when people are spending their own money on assets, they are likely to do so in such a way that protects the value of those assets. Aesthetics vary: every beautiful Georgian terrace we see—except those that were built on green fields—was built on land that previously held a beautiful row of black and white cottages from the 14th or 15th century that was knocked down to make way.
Imagine a world in which people could go along to a site and the sales agent with the pink Fiat said, “Here are some choices for you. You might want a big plot or a small one. Your tastes might tend in the direction of very traditional architecture or of something very funky. If the former, you might want to think about these architects and builders. If you want something more contemporary, you might want to consider these architects and builders who have a lot of experience in that sector. We have some examples of work they have done earlier and we can attest to their quality.” That could be the normal approach, but at the moment it is anything but.
Interestingly, the UK is an outlier in this area. In Canada, Germany, France, Sweden and Ireland, self or custom build often accounts for more than 50% of the market. In Italy, it accounts for more than 60% and in tiny Austria it is 86%. In this country, self-build is still seen as an elite club that is open only to a small number of people. As Kevin McCloud has said, we build some of the poorest-performing, most expensive and smallest homes in Europe. If someone wants a home with triple-glazed windows so that it costs nothing to heat, we have no suppliers who can supply that. I do not know anyone who would not like a house that cost nothing to heat, but triple-glazed windows are not available here, although they are in Germany. They should be available here, too.
