Chartered Building Company Specialising in Home Extensions

Avoid the disruption and cost of moving

As a Chartered Building Company, we are committed to delivering high-quality home extensions that transform living spaces while maintaining the structural integrity and style of a property. Our expertise, regulated by the Chartered Institute of Building (CIOB), ensures professionalism, reliability, and exceptional craftsmanship in every project we undertake.

Specialists in Single-Storey Extensions

Single-storey extensions are a versatile and cost-effective way to expand your home. An ideal solution to get that open-plan kitchen, spacious family room, or a private study, our team designs and builds extensions tailored to your needs. We work closely with you to enhance the functionality and aesthetic appeal of your property and integrate the new space with the existing structure.

Tailored Solutions for Every Home

We understand that every home is unique. Our design and construction process is customised to your specific requirements, taking into account your property’s architecture, local planning regulations, and your personal style. From contemporary glass-fronted extensions to more traditional brick builds, we bring your vision to life with precision and care.

Our Approach

Is built on trust, collaboration, and attention to detail:

Consultation and Design

We begin with a thorough consultation to understand your goals, budget, and preferences. Our experienced designers develop plans that maximise space, light, and functionality.

Planning and Compliance

Navigating planning permission and building regulations can be complex. Our team handles all necessary approvals to ensure a smooth process.

Construction and Project Management:

Using top-quality materials and skilled craftsmanship, we construct your extension to the highest standards. Our project managers ensure timelines and budgets are met, keeping you informed every step of the way.

Finishing Touches

We offer a complete service, including interior finishes and fittings, to deliver a ready-to-use space that exceeds expectations.
