Extending up on a block of flats?Make Text Bigger
Our block of flats is 3 stories tall and semi-detached to a 2 story house. The ground floor is a communal entry, and a tunnel through the carpark.
We are 50% freehold owners, and both us and the other freeholder agree that we would like to extend up if we can. Ideally we would like to add additional floor/s with standalone flat/s to the building.
Before proceeding I’m aware there are restrictions on how many floors you can add without the need for a lift, so the first question is how many floors we would be allowed.
In addition, I also wanted to explore using the space in the roof for the top floor flat, so wanted to find out when you reach the limit of the floors allowed from the communal stairwell, whether you can then have additional stairs/floor within the top flat (like a loft conversion), making the flat split level. Depending on the regulations, the options as we see it are as follows:
Option 1: Adding 1 new floor / standalone flat
Option 2: Adding 1 new floor / standalone flat, and in addition converting the roof so that the new flat has a second floor.
Option 3: Adding two new floors, each a standalone flat
Option 4: Adding two new floors, each a standalone flat, and in addition converting the roof so that the top flat has a second floor.
Any advice on what the limits are for extending upwards would be greatly appreciated.
