Basement Conversion Companies – Why You Should Choose G8 Builders


Basement conversions are a great way to add extra living space, cinema rooms, bedrooms, playrooms and more. They’re also often more cost effective than extending the property.

A structural engineer will design your ‘shell and core’ as a detailed package of works. This will include all survey information and calculations.

Many London homes are too small to maximise living space, so converting the basement is often more cost effective than extending the house above. This can create a stunning space that can be used as a family room, cinema room, games room or even a guest suite.

One of the key considerations when undertaking a basement conversion is whether or not the existing foundations can be supported safely by contractors working below ground level. This requires a geo-technical survey to be undertaken prior to commencement of works and can lead to the need for underpinning work.

It is also a good idea to liaise with your neighbours at the concept design stage so they are aware of the duration and impact of works on their property. Also, a party wall agreement will need to be drawn up and signed by all parties. This is essential to prevent any issues arising during the course of your basement construction project.

Were experts in basement excavation

When building a new home, adding a basement can be one of the best ways to add valuable space. However, building a basement requires extensive excavation work that is often complex and dangerous. This task is best left to a qualified and experienced excavation contractor.

A typical excavation process involves constructing load-bearing foundation walls, and then excavating a basement beneath them. This method has the added benefit of allowing a structure to be built above while the basement is being excavated below.

If a basement is being built on a site with a high groundwater table, it can be more challenging to excavate. Keller companies like HJ Foundation and Hayward Baker have developed a system that allows for economical construction of deeper basements in areas with a high groundwater table. The system works by incorporating soil mixing with CFA/augercast piles. This technique allows for the basement to be excavated while retaining water pressure and avoiding the need to pump water from the excavation site.

Were experts in basement design

With space at a premium in London, many homeowners turn to basement design to create additional living space for their families. However, it’s important to choose a specialist construction contractor that knows how to build below ground structures and comply with all the relevant regulations.

A basement designer can assess whether a conversion or excavation is feasible – both structurally and financially. They can also advise on any necessary underpinning, drainage requirements, basement waterproofing and tanking, safe heating options and electrical installation.

Existing Basements or Cellars in Period properties can be converted to provide extra space for a cinema room, games room, tv den, guest rooms, utility areas, swimming pools or additional storage space. A basement lift garage can even be built as part of a basement conversion. It can be a more cost effective solution than building an above ground extension.
