Building upwards is a great way to create more housing while also reducing urban sprawl. At the same time these projects can preserve green spaces. However, it is important to consider all the factors, including the property owner’s development rights. As a top architect London clients can rely on for great advice, we can help here.
Earlier this year the rules about airspace development changed. As a result people now have more freedom to add more storeys to existing buildings. With certain buildings there is now no need to get planning permission for this kind of project.
In terms of blocks of flats, the building must be detached and can be three storeys tall or more. Here it is possible to add up to two more storeys to create new homes.
However, one important thing to note here is that the building must have been built between 1st July 1948 and 28th October 2018. Older or newer buildings do not have the same permitted development rights.
The most important thing to think about if you are planning to add new floors to a block of flats is the structural stability of the building. The foundations may be sufficient for the current building but may not be able to handle the additional load. That may mean your project cannot proceed.
If there are concerns about the load on the foundations, it may be necessary to choose lighter materials. A good option would be lightweight modular homes. They can be much lighter than dealing with brick. There are also advantages such as a shorter build time and less labour on site thanks to prefabrication.
