Garage & Cellar Conversions

The best way to add living space and value to your home if you don’t have the room to extend elsewhere

The popularity of cellar and garage conversions in London has grown exponentially in recent years. With the costs and hassle associated with moving to a new house, more and more people are choosing to maximise the usable space within their home instead.

Depending on the year and location of the original construction, many houses across London have existing cellar spaces and garages, which often provide the homeowners with the option of converting mere storage or wasted areas into inspirational new rooms. Not only does this give you a way of increasing your living space but can also have the benefit of adding real value to your property and making it a more desirable prospect for future buyers. It also prevents you from losing valuable outdoor areas and incurring high structural building costs.

Here at Home Republic we specialise in transforming unused garages and cellars into beautiful rooms across London, Surrey and Kent.

The key to success in any basement and garage conversion project is to ensure the area is completely waterproof.

We supply and fit complete and comprehensive range of waterproofing and drainage systems, using the latest up to date products, including submersible pump systems, cavity drainage membranes and basement drainage systems to create the room of your dreams with the peace of mind you deserve.
