Benefits of a Garage Conversion

Most garages have some sort of electricity, whether it’s a single plug socket or a light switch, this will save you money as well.

When comparing building a small extension to a garage conversion, the garage would be substantially cheaper. A small four meter by three meter extension would range from £20,000 to £24,000, compared to a garage conversion which could be as little as £8000.

Structural Changes and Building Costs for Garage Conversion

The garage conversion will only require minimum structural changes at it has already an existing framework. However, there will be some structural changes to be made to make this in to an adaptable living space, here are some areas to consider:

Garage Door – Window and Brickwork

One of the first alterations required for a garage conversion will be the removal of the garage door. This area will need to be measured to add a window to increase natural light, if this room will be a sleeping area, then an escape window is required as part of building regulations. The remaining area below the window will require bricking up. The bricks will need to be carefully matched with existing bricks, so it will blend into the natural brickwork. Blockwork on the inside of the garage conversion will be required, this will provide a cavity, where insulation will be provided to keep the room warm.

Door into Garage Conversion

A door from the house into the garage conversion is an essential part of creating a natural extension to a property. The brickwork will require to be removed with a lintel fitted to secure the weight of the wall above the new door way. The door frame will then need to be fitted to match prevailing skirting boards of the home.

Walls – Plastering and Skimmed

Most garage conversions will require at least one stud wall to be built. Whether this is to provide cavity insulation or to obtain an additional partition i.e. bathroom. Stud walls are also used to split a double garage into two areas, one of which being the garage conversion.

Garage Conversion – Utilities

One of the major areas of unexpected costs of a garage conversion is the utilities. Many garages have some sort of electricity appliance however this may not be acceptable to apply an internal loop to install plug sockets and lighting. A radiator will also needed to be budgeted into this garage conversion especially if it will be an all-round living space.  If this conversion will be for a granny annex, then a bathroom, shower, toilet or even a kitchen will need to be taking into an account.


Regardless of the finish type of flooring whether it’s a new carpet or laminate, a structured base will be required. This will be either made from a wood structure or even a new layer of concreate. Regardless of the floor structure, it will still need to be level and brought up to the required height of existing floor of property. Consideration of the new floor will also need to be taking into account.

Garage Conversion Consideration

The cost of the garage conversion will depend of on many additional factors including what the new garage conversion will be used for. For example you may require a simple conversion including a window, brickwork and additional door, which should not be too expensive. However, if you require a new kitchen to be fitted or even a bathroom, then this will be much more expensive.

Administration costs will also be factored in such as applying to building regulations, or even planning permission (depending on what additional work is being done). Other influences would be if you require a loan to pay for such work, then interest changes should be added.

Regardless of any of these dynamics a garage conversion will be far cheaper than an extension or a conservatory. Garage conversions are a cheap way of increasing both the size and value of your home. A conversion is also an exciting way to make your home larger without the need of moving home.
