Sunbury’s home improvement and extension specialists

With the perfect combination of easy accessibility to central London and a beautiful semi-rural location, Sunbury-on-Thames is a great place to live. So, if you and your family need more living space than your home currently provides, it makes sense to see if you can create that extra space rather than going to the trouble and expense of moving!

Here at Highline Design & Build, we’re your local home improvement experts, including designing and building house extensions. If you have the space available – even if only for a small house extension – it’s a practical and cost-effective solution that could not only improve your family’s lifestyle but also add extra value to your property.

We can offer many types of home extensions, including:

Loft Conversions Sunbury-on-Thames

If your Sunbury-on-Thames home doesn’t have the external space for an extension, it may be that you could opt for a loft conversion instead. In fact, loft conversions are often a faster and more cost-effective solution, because the basic structure will usually already be there.

From large to small loft conversions, we can help create useful extra living space that could be used for anything from a home office or playroom to an extra bedroom with an ensuite bathroom.

Many properties are suitable for a loft conversion, with our range including:

Garage Conversions

Like lofts, garages are often underused spaces that can be relatively easily converted into something that is more practical, more useful and that can add extra value. Our garage conversion ideas mean your garage could be used for anything from a gym or an office to an extra bedroom, a home cinema or even a new luxury dining room. Quicker and easier than an extension, garage conversions are the perfect answer to improving the layout in properties short on internal living space!

How long will my project take?

Each project is different and the size of the build will determine the time it will take to complete; however, an average rear extension/loft conversion will take approximately six weeks from start to finish.

Will I be able to live in my property while the work goes on?

Yes, you will be able to live in the property. If this is the case, we will attempt to leave the breaking through into the house until as late as possible in the project.

Will someone be on site every day?

Yes, we will have someone on site every day. However, the caveat to this is if we are waiting on drying times or materials. That being said, we will endeavour to have a team member/team members present as much as possible to ensure the project is completed in a timely manner.

Will an extension add value to my property?

Absolutely, it is becoming more and more popular to add space to your existing property instead of the hassle and fees involved with moving. Adding additional square meterage can add up to 10-20% onto the market value.

Can you help with plans/designs?

Of course, we can offer suggestions and ideas, and show you previous projects. We can also arrange for you to visit a previous project if required. We have built relationships with trusted architects and can introduce you to our preferred contacts in order to obtain your drawings.

How long does it take to get planning permission?

It will depend upon whether you are applying for permitted planning or full planning permission. Different councils work to different timescales; however, as a guide from submission of plans it will take approximately 8-12 weeks.
