Basement & Cellar Conversions in the Cotswolds
If you’re looking to create additional living space without extending your home, a basement or cellar conversion is one of the most effective ways to unlock your property’s full potential. At Larian Construction, we specialise in basement and cellar conversions throughout the Cotswolds, transforming underused spaces into bright, comfortable and practical rooms that enhance both your lifestyle and your property’s value.
Whether you’re planning a home office, guest suite, family room, gym or entertainment space, our experienced team delivers fully managed basement conversion projects from the initial assessment through to final completion.
Basement conversions are specialist structural projects that require careful planning, technical expertise and high-quality workmanship. With extensive experience working on properties across the Cotswolds, including traditional stone homes and modern properties, we ensure every conversion is completed safely, professionally and in full compliance with current Building Regulations.
Every project is tailored to the individual property, creating a finished space that feels like a natural extension of your home.
Structural Alterations & Waterproofing
Creating a basement that’s suitable for everyday living requires much more than cosmetic improvements. Structural integrity, effective waterproofing and long-term durability are essential to the success of any conversion.
Our experienced builders manage every stage of the construction process, including:
- Structural alterations
- Excavation where required
- Reinforcement of existing walls
- Structural steel installation
- Waterproofing systems
- Damp protection
- Ventilation improvements
- Floor construction
- Insulation upgrades
- New staircases and access points
Professional waterproofing is one of the most important aspects of a basement conversion. We use proven waterproofing methods to help protect your investment from moisture ingress while creating a dry, warm and comfortable environment suitable for year-round use.
Working closely with structural engineers and Building Control where required, we ensure every aspect of the project is completed to the highest standards.
Designing Functional Living Space
A basement conversion gives you the opportunity to create valuable living space without sacrificing your garden or extending the footprint of your property.
Popular uses for converted basements include:
- Home offices
- Additional bedrooms
- Guest accommodation
- Home cinemas
- Family rooms
- Children’s playrooms
- Home gyms
- Utility rooms
- Hobby spaces
- Wine storage rooms
During the design stage, we carefully consider ceiling height, natural light, ventilation, heating, storage and room layout to maximise both comfort and practicality.
Our aim is to create a space that feels bright, welcoming and fully integrated with the rest of your home rather than simply converting an unused cellar.
Every finish is completed with precision to ensure your new living space offers lasting quality and everyday comfort.
