Types of Extensions for Your Home

1. Rear Single Storey
Possibly the highest value and most useful type of extension.
Terrace House – Typically 3m from the original rear wall
Semi Detached House – Typically 3m from the rear wall
Detached – Typically 4m from the rear wall
General – The height of the extension should be typically 3m at the eaves.

2. Rear Double Storey

These are possible but can be very tricky on terrace and semi detached properties as the width is the key aspect. Typically a second storey extension is possible if it is more than 2m from the boundary. Good results can be achieved on wide fronted houses and detached houses.

3. Side Single Storey
Typically up to half the width of the house can be achieved. Possibly up to the boundary but a 1m gap for garden access maybe more typical.

4. First Floor Side Extension
If the extension is pulled back from the front face by at least 1m and 1m from the side boundary 1m this can be a useful extension.

5. Garage Conversion
Usually not a problem in terms of planning as the building is already there. Garage doors can be replaced by windows to fit in with the house and street scene. The construction will need upgrading to make the garage into habitable space. So Building regulation approval will be required.

6. Loft Conversion
This extension can be very useful for an additional bedroom or office. Things to consider are the height of the ridge, pitch of the roof and overall plan size of the house. Just because you can stand under the ridge does not mean you can achieve a good loft extension. A dormer can be achieved to the rear only (not side or front).
