House Extensions in Egham, Twickenham & Weybridge

Whatever the long-term effects of COVID on our society, if there’s one thing it’s taught us it’s that our homes need to have the flexibility to accommodate the fact that we’re going to be spending more time there. 

With house prices continuing to rocket across the country, house extensions still offer a more cost-effective means of getting a bigger home than moving. And done right, you could also be adding considerable value to your property, so that you’ll likely be making back at least what you spend on it, should you decide to sell in the future.

That’s where Highline Design & Build comes in.

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.
