Professional house extensions in Colchester. We design and build rear, side and double-storey extensions with full project management and clear, itemised pricing.
A well-planned house extension is one of the best ways to improve your home without the stress of moving. At Colchester Builders, we create high-quality extensions that add space, comfort and long-term value. Whether you’re dreaming of an open-plan kitchen, an extra bedroom or a bright family living area, our team will design and build a space tailored to your lifestyle.
We handle everything — foundations, structural work, insulation, glazing, electrics, plumbing and finishing — ensuring a smooth process from start to finish.
Every successful house extension starts with understanding how you want to use the space. We work with homeowners across Colchester to design extensions that improve layout, natural light, and everyday functionality. Whether you’re extending for a larger kitchen, additional living space, or extra bedrooms, we focus on practical designs that integrate seamlessly with the existing property. Our aim is to create extensions that feel like a natural part of your home, not an afterthought.
We build both single and two-storey house extensions to suit a wide range of properties and requirements. Single-storey extensions are ideal for opening up ground-floor living areas, while two-storey extensions offer excellent value when creating space across multiple levels. Each project is planned carefully, with attention to structure, foundations, and finishes, ensuring the extension adds genuine long-term value to your property.
House extensions often involve planning considerations and structural work that must be handled correctly. We ensure all extensions comply with current building regulations and advise on planning permission where required. Structural elements such as steel beams, foundations, and load-bearing walls are carefully managed to ensure safety and compliance. By addressing these technical aspects properly from the outset, we help avoid delays and ensure a smooth build process.
Good project management is key to a successful extension. We manage the entire build process, coordinating trades, materials, and schedules to keep the project running smoothly. Clear communication is maintained throughout, with regular updates so you always know what’s happening. Our organised approach helps minimise disruption and ensures your house extension is completed efficiently, safely, and to a high standard.
We work throughout Colchester, Lexden, Stanway, Highwoods, Wivenhoe, West Bergholt, Tiptree and surrounding areas.
