You can expand up to 6 metres to the rear of a terraced property without applying for planning permission if you fulfill the allowed development conditions. These include limits on the height of buildings and the amount of land that can be developed. It is a good idea to discuss any plans with your local council before you start construction as they may have different views on what should be allowed at the end of the street. For example, some councils will not allow new roofs to be placed on houses as this can change the appearance of the building significantly and make it look like a block of flats. Others may view this with less concern since people living in apartments above the shop downstairs probably have access to the roof anyway! End-of-terrace properties were common in London when building regulations were less strict. They are still widely used in more affordable areas where space is limited. You often find these houses built around a courtyard that is open to the front and the back. This means there is no need for separate entrances for each house, just one door that leads into the communal area. The houses are usually one floor with small windows and low ceilings. They are usually rented out as let rooms or used by landlords as rental income streams. There are also a lot of pubs and restaurants in these areas so there is always demand for housing.
