House Extensions by George Stone Limited

Extensions are just one of our specialities, offering a cost‑effective way to add space and value to your home. From planning permission to construction, we guide you through every step of the process with expertise and care.

In many cases, single‑storey extensions such as kitchens may not require planning permission, though Building Regulations approval is always necessary. For two‑storey projects, different rules apply — and we’ll be happy to advise you and recommend trusted architects to help design your space.

We also encourage consultation with neighbours and careful planning to ensure your extension blends seamlessly with your existing property.

At George Stone Limited, we believe changes are best made on paper, not halfway through a build. That’s why we work transparently, never ask for money up front, and operate on fortnightly or monthly billing.

Costs vary depending on size, complexity, and site conditions, but permits typically range from £300–£600, and construction averages between £1,000–£5,000 per square metre.

Barn, Church & School Conversions

Farm buildings, churches, and schools offer incredible potential for conversion — but location and regulations can greatly affect the return on investment. Barn conversions, in particular, are highly popular, though strict guidelines apply.

• Roof lines and dormers cannot be altered
• Rooflights must be minimal and discreet
• Existing openings must remain unchanged
• Original materials should be repaired wherever possible, with replacements using reclaimed or handmade alternatives

Barns vary by region — timber, brick, or stone — with stone being the most expensive to convert and brick the most cost‑effective.

Design features such as glazed panels between timbers, statement staircases, and industrial‑style steel, glass, and chunky timber can transform these spaces into stunning contemporary homes.

At George Stone Limited, we have extensive experience in barn and outbuilding conversions, as well as garage and loft conversions to create much‑needed extra space in your property.

Building & Property Maintenance

At George Stone Limited, we are proud to have been entrusted by the National Trust and East Sussex County Council to maintain and repair their properties. Our portfolio includes some of the most prestigious buildings in the South East, as well as extensive work for Housing Associations and Local Authorities.

We are committed to tenant satisfaction, consistently praised by social housing providers and residents for our professional approach. Every project is overseen by a dedicated Contracts Manager, ensuring clear communication and minimal disruption.

Respect and understanding are central to our work. All operatives are DBS checked and carry identification cards, providing reassurance to residents during what can often be an anxious time.

We also specialise in disabled adaptations, helping individuals maintain independence and quality of life. From bathroom and kitchen modifications to improved access solutions, we deliver practical, high‑quality results. Local council grants may be available to assist with costs, and we are happy to guide you through the process.

Structural Maintenance

At George Stone Limited, we specialise in structural remediation and maintenance projects of all sizes. Our experience includes removing load‑bearing walls, demolitions, and underpinning work, all carried out with precision and care.

With a trusted network of architects, structural engineers, quantity surveyors, and trade specialists, we deliver seamless construction services. By law, we are provided with detailed information about a building’s structure, stability, and form — and we use this to plan and execute every project safely and reliably.

Following a thorough structural survey and assessment, we determine the necessary steps to prevent collapse, including the design and installation of temporary supports before repair work begins.

Once the building is secure, our dependable team of decorators takes the project to the next phase, ensuring a professional finish. We are proud to have been recognised by the Sussex Heritage Awards for our excellence in decoration and restoration.
