Benefits of Converting a Basement

Basement conversions are becoming increasingly popular in the UK, especially in places like cities where space is at a premium. Already a popular trend in London, homeowners across the UK are catching on to how utilising the unused space under a property can bring all sorts of benefits not only to your lifestyle but also to the value of the property. 

A perfect addition to any house within a city, basement conversions allows city dwellers the best of both worlds, they can extend their existing living area without having to give up on outdoor space. 

Most people would be surprised at how much space can be created with a basement conversion as they open up the dimensions of the property on a large scale, giving the homeowners a wide choice of options to benefit the vision for their home. The possibilities are truly endless with popular choices being an at-home gym, cinema room, game and crafts room, or even something simpler like an extra living room, or home workspace. 

These types of rooms lend themselves to basement conversions perfectly when compared to other extensions like a loft conversion. Functionality is key in any home and having an extra living room or games room situated upstairs away from the main living areas can often be impractical. 

Another benefit of a basement conversion that cannot be overlooked is the added value it can attach to your property. In cities and highly sort after areas, a basement conversion is estimated to increase the value of a property up to 30%. You can even make money from the basement conversion whilst living in your property by turning it into a self-contained unit for lodgers and Airbnb guests, creating this type of unit under a house ensures far less disruption and more privacy for you as a homeowner while still being able to profit. Additionally, extra entrances for a rented basement conversion only increases the potential rental income.

Our team of specialists will ensure that waterproofing is done right and can be confident that your basement conversion won't suffer from damp or leakage.
