Convert Your Garage, Into a Pratical Living Space

At Greenoak Concept & Design, we offer a practical and cost-effective garage conversion service designed to create valuable extra living space within your home.

As a family-run Essex home improvement company, we have extensive experience across a wide range of property improvements and specialise in high-quality garage conversions.

From initial design through to completion, we know what we’re doing when it comes to converting garages, so you can have complete peace of mind that your home is in safe hands.

Our aim is to provide a smooth and stress-free garage conversion. We take care of building regulations, Part P electrical certification and any planning permission where required, alleviating the worries that can often come with conversions.

If you need extra space, a garage conversion is one of the most effective ways to extend your home, creating a larger living area while adding real value to your property.

Whether you’re looking to create an extra bedroom, living space, dining room, bathroom, home office, playroom, granny annexe, teenage room or home cinema, we’ll tackle the project from start to finish with minimal disruption and mess.

If you have a garage and need an extra room, converting it simply makes sense.

When you compare the cost and disruption of moving house with a garage conversion, the difference is clear. Stamp duty, estate agent fees, increased mortgage costs, removals, decorations and furnishings all add up quickly.

Much of this expense is unrecoverable, whereas a garage conversion allows you to invest in improving your existing home.

By creating additional living space, a garage conversion can increase your property’s value and provide a strong return on investment.

All of our work is fully guaranteed, and we carry full public liability insurance for complete peace of mind.

Permitted Development

The type of garage conversion you choose may be influenced by building regulations, and in some cases planning permission may be required.

In many situations, converting a garage is classed as permitted development. This means planning permission is not usually needed, provided the work is internal and does not involve enlarging the building. If your home is listed, listed building consent may also be required.

We manage all building control requirements throughout the entire process, so you don’t have to worry about compliance.

Pre-start

You may not need planning permission, but building regulations mean that if you’re converting a garage (or part of one) into habitable space, you’ll normally need approval from your local authority. So, before work begins, you need to decide whether to submit a building notice or plan building regulation application.

A building notice application doesn’t call for pre-approved plans on smaller projects. Building work can get underway quickly and a building inspector will approve the works as they’re carried out. However, there are situations when a building notice can’t be used: visit Planning Portal to find out.
