Choosing a single or double storey extension

26th October 2021

One of the ways to improve a home’s layout and add on its value is to add a storey extension. It is the best way to make the living room spacious. For instance, it makes it possible for one to create enough space in the kitchen and transform it to a kitchen dinning space. You can also get an extra bedroom or bathroom upstairs. Lastly, one can utilise the extra space for utility room, cloak room and boot room. Furthermore, the costs are minimal because most of the structural work is in place.


The differences between single, double and side return extensions

Single storey

It is added to the rear and occupies the downstairs of the property. Sometimes one can extend the entire breadth of the house. This is common with people who have a garden space hence may opt to add a few meters of the garden space to the house. In such scenario, one is obliged to add a second floor extension above an already established ground floor. One can use a flat roof or a pitched roof with simple skylight windows. There can also be lantern windows to full glass roof. The party wall agreement is needed to protect the neighbour’s property.


L-shape, side return or wraparound extension

This are the kind of extensions that make use of the underutilised areas. Some houses have unused areas around them. These areas can easily be converted to a single storey extension. Examples of these underutilised areas are the garden to the side and rear of the property. These areas can be exploited by integrating it into the building. This kind of extensions have utility and aesthetic advantages since they enable the owner to turn what was initially squeezed room into a spacious house. This process entails knocking walls down to create an open plan space on which the designer creates a new design. To effectively carry out the extensions, one should consider the ceiling height and light levels.


Double storey or multi storey extension

Double storey or multi storey extensions are more expensive than a single storey extension. However, multi storey extensions gives the owner more space for their money than the single spaced extensions. Double storey extensions gives the owner an option to either create a larger version of the existing rooms or create completely new ones.

Since the extensions are likely to alter the look of the property, there is need for gaining planning approval that may prove to be involving. Furthermore, it is likely to affect neighbouring properties in terms of light and view.

In conclusion, single storey extensions are less expensive and requires minimal logistics in approval but they add one less space compared to double storey extensions. On the other hand, the double storey extensions require planning approval that may involve a lot of logistics because of a lot of work involved that can affect the neighbouring properties in terms of light and view. However, double storey extensions give the owner more space.
