If you dream of living in your own home that you have designed and built, but also want to live in London, then you might think you are not able to buy a plot of land in a city that is so notoriously crammed full of buildings already.
However, although you are not likely to find any greenfield land in London, you are likely to find brownfield land, this could be a building that is in a bad way, that can be knocked down and rebuilt on, or land that was previously used for industrial reasons for example.
Once you have found some land that you think would be suitable to build your house on, you then need to make sure that it is suited to what you want, is within budget, and also that you can get the right planning permission to be able to do what you want, so you should consider all of these things first, and speak to a professional architect like this residential architects Kensington based company https://www.rbddesign.com/architects-design/residential-architecture-london/architects-kensington-and-chelsea/ who will be able to design the house with and also help you navigate planning.
Another thing that you need to consider when you are buying brownfield land is the fact that it may be contaminated. This means that you have to clean it up before you can build on it, but this is not something that you can do yourself, you need to get a professional to do it for you.
