Depending on your location, an extension of a basement could add 30% to the value of your property.

If you’re looking to add a basement extension to your home, it’s important to check with local estate agents and see if this is a viable option to increase the value to your current home.  If it’s a new build you won’t have these concerns provided that the plot ticks various boxes – such as the space is well drained not subject to flooding.

It’s important that for any outlay you get redeemed for it.  This will depend much on the value of your home and the area you stay.

A suitable case for digging

In what instances can a basement not be implemented? In areas where their homes are close to rivers and where local services are running under the property can make it difficult to extend or transform your basement.  Local government mention that there is more risk of flooding, the closer you are to high water so there’s more difficulty to get the job done in this respect.

When there’s a solid floor, the prospect of a basement can also be difficult. It might not be feasible to fit a basement in this instance.

Cavity drain membrane system

Up until the last 15 years, basements were built by being dug out and then finished with cement. No waterproofing was taken into consideration.

Leaks would then inevitably occur after several years, increasing the reputation that basements were a place that was susceptible to dampness and flooding.

In today’s world, basement projects are excavated and the foundation of the build, underpinned with waterproof concrete while the whole inside of the basement is tanked with a waterproof membrane covered in studs.

This cavity membrane system is installed so for any water build up is detected, it helps drain it away and keeps the cellar dry and waterproof.

Do you require planning permission?

If you’re creating a basement and are excavating, you would need planning permission from the relevant authorities however if you’re simply adapting an already existing basement and the work is internal then it’s doubtful you’ll need planning permission.  In any instance check before. With new building work, it needs to meet the usual building regulation requirements.

If you have neighbours, you’ll need to written consent from them before commencing any work if you share a wall where the basement extension is happening.

Will it take a long time?

The time to complete your basement extension will depend on numerous factors.   Such as how much building work is required, and the amount of excavation needed. Although on excavation projects it can be disruptive, the work is completed externally and not internally. The work is effectively sealed off at ground level.
