Basement Construction in Sussex, Buckinghamshire and the Surrounding South East Area

Horner Foundations, a specialist in bored piling, mini piling and underpinning, can bring a wealth of experience to domestic and commercial construction projects. We pride ourselves on the delivery of a diverse range of services for both sectors, and basement construction is just one way in which we can assist our clients. Our talented team can construct basements for new builds or, for existing builds in the South East area, we can also retrofit.

Based in Hampshire, we cover the surrounding Berkshire, Buckinghamshire, Kent, Surrey and Sussex areas. With full project management capabilities, we can serve your project as a main contractor, or as a subcontractor for other building and construction companies, main contractors and developers.

If you have been considering a basement for your current home, or if you have planned to have one included in the design specification of self-build project, our structural engineers and tradesmen are here to assist you.

We invite you to view some of our previous projects in the local area, and to see the standard of our basement construction work for yourself.


Committed to Quality Construction

Horner Foundations understands that each basement project is unique. No matter how complex your requirements or how many challenges we face with ground conditions, our team of highly skilled professionals collaborates with you to determine the best construction method for new and retrofitted basements. We place a strong focus on soil strength, intended use and the standard of our workmanship, but we are also attentive to your needs when we retrofit into existing properties and always aim to minimise disruption.

Our knowledge of foundations, piling and underpinning allows us to employ advanced engineering and construction methods. We create strong, stable, and functional basements that add size and value to a property.

Retrofitted Basements

A retrofitted basement is a below-ground structure built underneath existing buildings to create extra living or workspace, and to increase the overall resale value of the property. Basement construction is an excellent choice for homes where conversions and extensions might not be possible because of size limitations or potential planning issues. We offer a full structural design, construction service, leaving you with finished basements that you can fit out with the functional features you need for intended use.

The challenges we face with the demand for larger and deeper basements is easily met thanks to our experience with all foundation types, the use of reinforced concrete, retaining wall construction and underpinning.

We understand that basement construction work for an existing property will be at least a little disruptive, and this is unavoidable. Even so, we take our obligations to our clients seriously and never forget that our workspace is your home. While we are working on your property, we will be clean, tidy and well organised, and we use rigs and systems which help to minimise disruption.

New Basement Construction

If you are running a project in Berkshire, Buckinghamshire, Hampshire, Kent, Surrey or Sussex, and if a basement is to be included in the design, the team at Horner Foundations can offer a start-to-finish service to include the building of the structure it prior to handover. Because more new homes are having basements included into the design to provide extra living space for owners and tenants, having our team at your disposal is a major benefit and one that takes incredibly specialised work out of your hands.

In fact, basement construction can make new builds more attractive to any potential buyers because they can be set aside for use as extra bedrooms, home offices, home cinemas, gymnasiums or relaxation space.

Some basements even have swimming pools included in the design.

The exorbitant cost of land and constraints applied by planning departments make it more difficult to build larger homes, so basement construction is just as much an economical solution as well as a functional one. We have our own structural engineers who can design basements on your behalf or, if you already have a specification in place, our team can work to your drawings.
