There’s always lots to think about when considering a building or extending a garden basement in the UK. Adding a basement with access to your garden can add space to your home that can be enjoyed in a variety of ways. It can also add significant value to your home if you ever decide to sell it. However, this type of project does need an expert approach to ensure its success.
Being clear on what you want and need
Before you leap into building the basement of your dreams, it’s probably a good idea to pause and think about what you want the basement for. A garden basement in the UK can be used for many purposes, and it’s generally useful to have a detailed plan before you start. Are you thinking of a home cinema, a gym or guest accommodation? If you require extra bathrooms or even a kitchen, this could affect the development. Effective plumbing is essential to the success of a garden basement in the UK and needs to be factored in from the beginning.
Another important consideration is ventilation, which ensures the quality of the air in the basement while also reducing the risk of condensation and damp problems. You will probably need to have the site surveyed to understand the topography and where all the drainage is located, so the developers can work with this and update it when necessary. Ineffective drainage can be a source of leaks which will cause significant issues.
If you have large trees in your garden, you may need to consider how the development will affect them and what impact the trees and their root systems could have on foundations or damp issues.
Light sources also need to be considered. There are clever ways of bringing more natural light into a basement, and these should be investigated at the outset. Skylights and light wells can increase the light quality in the basement significantly, and any direct garden access and doors will help much more.
Expert damp proofing for your garden basement in the UK
You may need to get appropriate planning permission and also work with your neighbours. If you communicate with them pleasantly and clearly, they are more likely to accept the noise and disruption that will accompany the building work.
As your basement will be surrounded by soil that retains water, damp proofing is another significant area to consider when it comes to planning. There are various techniques to keep your new basement dry, from sump pumps to water-resistant coatings and additional drainage. Because each site and basement are unique, working with a competent basement developer with a proven track record is essential.
A leaking basement can be difficult and expensive to fix, and it’s generally more time, energy and cost-efficient to have the site thoroughly assessed, and professional waterproofing built into the design from the very beginning. The type of waterproofing can also affect the kind of insurance you can obtain for the basement, so it’s vital to have this correctly implemented.
