Garage Conversions in Portsmouth, Hampshire (78)

Compared to extensions, garage conversions are relatively quick to complete. The actual time required to convert your garage will depend on:

• The size of the garage

• The condition of the garage

• The complexity of your plans

• Any extra work needed on the foundations

• Whether you’re adding plumbing and electrics

• The materials you plan to use

  So, roughly how long does a garage conversion take? Bearing the above factors in mind, most garage conversions take between 3 and 6 weeks. Read our handy guide for more information and advice about how long garage conversions take.

While extensions eat into your outside space, garage conversions make better use of a space that already exists. This means they are less expensive than paying for a full extension.

To predict the average cost of your garage conversion, consider the following:

• How large your garage is

• The condition of your garage and whether structural changes are needed

• If you plan to add utilities

• Your location

• If you need to replace a current garage door

• What you’ll use the garage for

• The quality of materials you use

• The type of garage conversion e.g. attached, detached or double garage conversion

Garage conversion cost

For a single garage conversion you can expect to pay around £14,500. If your garage is detached however, this will rise to around £20,000. A partial garage conversion can be much cheaper, at around £7,000.
