The Basics of Garage Conversions

Although half of all properties in the UK have a connected garage, less than a quarter of homeowners actually use it to store their vehicle. Instead, it usually doubles up as a utility or storage room.

What some people don’t bear in mind is the garage’s potential as an additional living room. At MPK Lofts, our garage conversions not only provide extra space within the home but also enhance the property value.

If this is a venture you’re considering, we’ve put together a basic guide to how a garage conversion works. For any additional information, please feel free to get in touch with us today.

Typical Costs

A typical garage conversion will work with the existing structure so won’t be as expensive as perhaps first thought. Of course, that said, everything depends on the size, shape and design of the room. Estimates are therefore wide-ranging, starting from around £7,000 to over £20,000.

In some cases, it may be more effective to knock down the existing design and rebuild from scratch, especially if the original structure is unsound. Of course, a conversion specialist will let you know early on if this is required.  

Also, remember that, despite the initial outlay, a garage conversion can add significant value onto your property. Research suggests a new bedroom will increase its worth by £40,000, with a study or playroom adding around £20,000.

Planning Permission

Many residential garage conversions will be classed as a permitted development – this means that planning permission won’t be required. However, this will change if we have to alter the face of the property. Obtaining permission is also required if you’re in a conservation area, business premises or listed building.

As our work will turn your garage into a habitable space, we’d have to apply for a ‘change of use’ approval on your behalf. We’d have to assure the room is made damp proof, energy efficient and has safe electrical appliances.

Our solid and long-lasting connections with local authorities helps with this process, although it can cost around £300 to be completed. In addition, a certificate of lawful development comes at a price of £86, with full planning permission at £172.

Design Considerations

The basic outline and design of the garage will shape how the conversion is carried out. Of course, the task of creating a viable living space and not just a ‘spruced-up’ garage is the challenging part.

For example, the old garage door must be replaced with brickwork and windows that match the existing property aesthetic. The position of the door can also be moved for better access, whilst fitting extra windows is often required.

Thought must also be made to ventilation, insulation, heating, electrical appliances, plumbing and the condition of the roof. Garage floor levels are usually lower than the main house so may have to be raised.

With these complex considerations in mind, our team of conversion specialists will explain how the process works during the planning stage. We’ll gladly answer any queries along the way and be upfront about ongoing costs too.
