Basement Conversions in Watford and Hertfordshire
A basement conversion can unlock a huge amount of potential living space, right beneath your feet. It’s an ideal solution for creating extra bedrooms, a home office, a gym, or a media room without altering the footprint of your property. Our expertise ensures a watertight, structurally sound, and stunning result.
Basement Building — Creating Liveable Underground Spaces
We are experts in the entire basement building process, from the initial excavation to the final fit-out. Our team handles every aspect, including structural work, waterproofing, and insulation, to create a comfortable and habitable underground space that meets all building regulations.
Cellar Conversion vs. Basement Conversion — What’s the Difference?
While the terms are often used interchangeably, a cellar is typically a space below ground level with a low ceiling, used for storage. A basement is a more substantial, deeper space, designed to be a full-height, habitable room. We have the expertise to handle both, whether you're converting an existing cellar or excavating to build a new basement from scratch.
Cellar Basement Conversions — From Storage to Living Space
Our cellar-to-basement conversions are a popular choice for homeowners. We can take your damp, underutilised cellar and transform it into a dry, warm, and inviting living area. This process often involves underpinning, waterproofing (tanking), and creating a new structural floor.
Convert a Cellar to a Basement — Step-by-Step Process
We manage the entire conversion process for you. This includes a detailed site survey, design and planning, expert excavation, structural underpinning, professional waterproofing, and the installation of ventilation and drainage systems. We work closely with you at every stage to ensure your vision is realised.
Basement Extensions — Adding Space Without Moving House
A basement extension allows you to add significant square footage to your property without extending above ground. This is a perfect solution in areas where garden space is limited or planning permission for above-ground extensions is difficult to obtain.
Cellar Refurbishment — Upgrading Old Structures
If your cellar is already a useable space but needs a modern update, our refurbishment services are ideal. We can waterproof and insulate the space, install new flooring and lighting, and undertake any structural repairs to make it a more functional and attractive area.
Barn Conversions in Hertfordshire
Hertfordshire is home to many beautiful old barns and agricultural buildings. Converting these heritage structures is a sustainable way to create a unique and character-filled home. At JFL Construct, we specialise in the groundworks required to support these stunning transformations.
Barn Converted to House — Turning Heritage Buildings into Homes
Our team provides the essential groundwork services needed for barn-to-house conversions. We prepare the foundations, install drainage systems, and lay the ground floor slabs, ensuring a stable and secure base for your new home while preserving the building’s historical integrity.
Barn Conversion Extensions
Many barn conversions benefit from modern extensions to provide additional living space or to connect new and old structures. We handle the foundational work for these extensions, integrating them seamlessly with the original building’s structure.
Barn House Conversions
We understand the unique challenges of converting barns into modern homes. Our expertise in groundworks ensures that the new structure is built to the highest standards, addressing issues such as uneven floors and weak foundations to create a solid base for your new barn house.
New Build Barn Conversion
For projects that require a ‘new build’ approach to a barn conversion, we provide all the necessary groundworks, including deep excavations and the construction of new foundations. This is often the case when a barn is beyond structural repair but the aesthetics and location are to be retained.

At JFL Construct, our experienced staff is always happy to provide expert advice and guidance based on their decades of expertise in the industry. These are some of the most common questions we receive, along with the appropriate answer.
How much does a basement conversion cost in Watford?
The cost of a basement conversion can vary significantly based on the size of the space, the depth of excavation, and the complexity of the project. Factors like waterproofing, underpinning, and the final fit-out all play a role. We recommend a free site survey to provide an accurate, no-obligation quote.
Do I need planning permission for a barn conversion in Hertfordshire?
Yes, a barn conversion almost always requires planning permission. The process can be complex, and we recommend working with an architect or planning consultant who specialises in these projects. We can provide technical advice to support your planning application regarding groundworks and structural considerations.
Can I convert a cellar to a basement suitable for living?
Yes, in most cases, a cellar can be converted into a habitable basement. This process involves a full structural survey to assess the feasibility, followed by professional tanking (waterproofing), insulation, and the installation of a proper ventilation and drainage system to meet building regulations.
What are the challenges of barn conversion extensions?
The main challenges include ensuring the new extension is structurally integrated with the old barn and that the design complements the original character of the building. Groundwork can be particularly challenging due to the age and potential instability of the original foundations. Our expertise in groundworks helps to mitigate these risks.
How long does a basement extension usually take?
The duration of a basement extension depends on the size and complexity. A typical project can take anywhere from 12 to 20 weeks from start to finish. This includes excavation, structural work, waterproofing, and the final fit-out. We will provide a detailed timeline as part of our quote.
