Home Refurbishments

We understand the process for planning applications can be extensive and stressful. The last thing you probably want to do is read and try to interpret the fine print and navigate the regulations. We’re here to help guide and support you through the process. 

If you are worried about whether you’ll require planning permission for your extension, we can help. We provide you with expert advice on extensions for both regular homes and listed. 

All of our work is carried out in accordance with the regulations set out by the local authority in Oxfordshire, so you can be safe in the knowledge that you won’t receive any nasty surprises. 

Bricklaying Extensions

As ever, we understand that people are money conscious and are looking to save wherever possible. If you choose the right project, however, you can add significant value to your property when you come to sell. Are you looking for an extension for £20,000? Or maybe something between £30,000 and £50,000? We’ve got ideas to suit all budgets!

Here is a rough guide, if you are planning a single-storey extension and what you should expect to pay (for building work only):

  • Around £1,750 to £2,000 per square metre for basic quality
  • From £2,000 to £2,500 per square metre for good quality
  • Between £2,500 and £2,750 per square metre for excellent quality

Kitchen Extensions Oxfordshire

The kitchen is the heart of every home, so why not make it bigger? As a space for both entertaining and cooking this would be one of the most logical parts to extend. Why not integrate your kitchen and dining area into one large open plan, free-flowing space? This can be achieved in a number of ways such as adding a large kitchen island with integrated breakfast bar, creating a more communal and social space.

Conservatory Extensions Oxfordshire

Take advantage of our bespoke conservatory design services to create a beautiful space that’s both stylish and flexible. Every one of our conservatory projects are specifically designed to suit the aesthetic of the home, built in varying shapes and sizes. These structures can be installed with double glazing, so you can enjoy the space all year round. Conservatories are also considered a permitted development meaning that they should be exempt from requiring planning permission.

Flat Roof Extensions Oxfordshire

If you’re looking for a more contemporary look for your home, a flat roof extension is a popular route to achieve this. Flat roofs provide that additional space but offer a cheaper alternative to those with a pitched roof, due to requiring fewer materials to construct. Flat roofs are also more environmentally friendly and thermally efficient. We can also offer a repair service if you are looking to maintain your extension.

Loft Conversion Oxfordshire

Loft conversions are a great way to make use of the wasted space and achieve more practical and functional space. A benefit of converting this space is that you don’t lose any garden space either! The most commonly fitted style of loft conversion is a dormer. We can provide you with advice as to which conversion will be most appropriate for your space. A loft conversion also falls into the permitted development category.

Benefits of Home Extensions in Oxfordshire

Increased Property Value

The main aim of enhancing or improving your home is to eventually increase the value of your property when it comes to selling. Whether you’re re-designing a home you intend to sell or looking for extra space for your family, extensions will provide you with that extra added value. Adding an extra bedroom can increase the value of your property by up to £20,000 in Oxfordshire. Attractive extensions such as a conservatory or kitchen extension can be appealing to future prospective buyers.

A Great Selling Point

Stand out from the crowd. Extending your home can provide your house with something different from the other houses in the area. Not only does it provide extra functional space, especially if larger families need a space to relax, but is also a stylish and unique feature that can be a great selling point when it comes to moving home.

Space Efficient Homes

If your house benefits from a larger garden, driveway or space to the side of your house, then extending into it won’t leave you short-changed for outside space, but provides you with more practical space inside your home. Extensions with dual purposes are a great way to make use of the extra space. Conservatories provide you with a showcase for your garden as well as a relaxation or dining area. Similarly, a porch provides extra space for storage whilst also providing security benefits.

Lifestyle Changes

If your lifestyle has changed significantly, then adapting your house to suit would be a beneficial investment. Creating a work-life balance is also important, not only for providing the perfect working environment but also for being able to separate yourself when you need to. Creating an office space for those who work regularly from home is a great place to work and can also be closed away at the end of the day.


Once you’ve gotten in touch with us about your project, we’ll organise a suitable time to visit your property. During our visit, we’ll determine your requirements and take essential measurements of the space.


Within 24 hours, we’ll supply you with a detailed quote of the costs involved including labour and materials. We always aim to administer the best value price we can offer, which won’t change once you have been provided with a valuation.


Once confirmed, we’ll start getting rid of any fixtures and fittings that are no longer needed. These will be disposed of in a professional and environmentally-friendly way. Any changes you require will be accommodated and adhered to by our specialist team.
