Extensions
Home Extensions
A Bellco Construction extension is more than just extra space. It is an investment in the way you live.
We work with homeowners across Sussex who want to enhance their properties with high quality, carefully built extensions that complement the existing home while adding light, space, and value.
This is where Bellco began, delivering exceptional extensions for discerning clients who value detail, precision, and long term quality.
We believe homes should be designed for real life, not just the brochure. Spaces that feel good to live in and stand the test of time.
Our Expertise
We deliver all types of extensions, including side, loft, two storey, three storey, basement, and kitchen extensions.
We take on extensions from around £100,000 up to £1,500,000, with each one receiving the same attention to detail and premium standard of finish as our new build homes.
We handle every stage of construction in house, using the same experienced management and trades teams that deliver our new developments.
Every project is built to the highest standard, managed closely, and finished to the quality Bellco is known for.
Design and Preparation
Get in touch wherever you are in the process. If you already have drawings or a full construction package, we can quote from them straight away.
If you are at concept stage, our in house design team and trusted architects will help you shape the design around planning, budget, and how you actually want to live.
We will always aim to get to a full construction package before quotations go out, so that you are comparing apples for apples across contractors. We will help you get there.
Building With Precision
Our experienced construction and management teams ensure your extension is delivered with exceptional craftsmanship and efficiency.
Every build is closely supervised, with clear schedules, budgets, and communication from start to finish.
Depending on the type and scale of the extension, clients can sometimes remain in the property during the works.
We understand how disruptive major works can be, and our site teams manage every project carefully to minimise inconvenience.
Finishes and Quality
We bring the same high end specification and finish from our new builds into every extension.
Premium materials, considered detailing, and seamless transitions between old and new create homes that feel unified and complete.
Whether it is a glazed kitchen extension, a double storey addition, or a full basement conversion, every detail is built with care and longevity in mind.
