I quite agree Luckygirl. Nearly 50 years ago, on a very tight budget, we bought a new, typical 70s build. Our parents said it was 'jerry built' (!) many of our friends were too nice to say it was characterless (but looking at their choices, I'm sure they thought it!). Some, more tactless, said so.
But it was light, and, for the times it was built, well insulated so our bills weren't high.
Of course, that estate was full of people just like us. When the time came to move, we actually bought another slightly larger house on the same estate. Our son married a girl from just round the corner, and now they live in a very similar house.
When we were finally able to build our own house, we took so many features from that 'characterless' house into our design.
As long as you can afford it, modern glass technology means you can have a large window that is still reasonable insulated, and of course, cover it with thick curtains at night. You can even get 'one way' glass if concerned about folk seeing in. And a favourite of self builders are 'sun tunnels' to make the most of darker corners. This is a link to Velux, who I think have the best website, and good features, but you can get them more cheaply as many DIY places: www.velux.co.uk/products/sun-tunnels
