“We knew roughly what we wanted but there were a few question marks and decisions that we felt were not sitting right. Ali came and gave a clearer picture and what he felt was best design and flow for our project. Clear, easy, to-the-point and allows us to progress knowing money invested is well-spent and not a design error - would 100% use again”

“A very thorough service indeed. Just what I would expect for the money paid. I cannot comment on the architectural ability as we had a very specific plan already set. Very easy to deal with, punctual and courteous.”

Frequently Asked
Questions

Single storey extensions must meet certain criteria in order to be exempt from a full planning application. For example, the extension must not exceed the rear wall of the original house by more than three metres. Your architect will be able to advise on whether a planning application is necessary.

Single storey extensions are the most common type we at The Architects of London work on. They represent one of the best ways to add space and value to your home. Many people find that a single storey extension provides a cheaper alternative to moving house, and that it brings the extra living space they require.

This really depends on the scale of the extension and your requirements for the space. Build costs are estimated to be between £1,500 and £2,500 per square metre as of 2023, but you will also need to consider what the space is being used for. If it’s simply a living area, this will be less expensive than if you are replacing a kitchen or adding a bathroom.

Again, this depends on the nature of your extension, but typically we expect the build phase of a single storey extension to take between 12 and 16 weeks to complete. To that you’ll need to add the design process and the time it takes to get the necessary permissions and regulations approved.

There’s no reason why you can’t continue to live at your home while it’s being extended. The level of disruption depends on the type of extension you’re having, but many people are able to remain at their property during the build.

While it’s not legally necessary for you to employ an architect for a single storey extension, there are clear benefits to using one. For example, an architect can make suggestions you may not have considered, and help you determine where to allocate your budget for the best results. At The Architects of London, we provide a full service, where your architect will be with you from planning right through to completion, taking care of all the essentials on your behalf.

At The Architects of London, our architects take an active role in your extension. Not only do we provide drawings and plans, we also liaise with contractors on your behalf, manage risks and carry out administrative tasks. This often translates into shorter construction schedules and even reduced costs.

Typically you can expect a single storey extension to add 5-8% to the value of your property. Of course, exact values will depend on the size and style of the extension.
