Double Storey House Extensions in Egham, Twickenham & Weybridge

You can add significant value to your home, as well as dramatically extend its living space, with a double storey house extension by Highline Design & Build.

Double storey extensions can represent far better long-term value than other extensions, as you’ll be creating a great deal more extra space for your money. Many of the costs, such as for the roof and for excavating the foundations, will be the same as for a single storey build, so you’ll be getting possibly twice the living space for considerably less than twice the cost!

Here at Highline Design & Build, we’re experienced in all kinds of house extensions, and can offer customers in and around Egham, Twickenham and Weybridge high-quality double storey extensions at a surprisingly affordable price.

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.
