House Extensions in Manchester and Cheshire

Thoughtfully Designed, Professionally Delivered.

A well-planned house extension does more than add square footage. It improves flow, enhances light, and reshapes how your home supports daily life. With over 40 years of experience across Cheshire and Greater Manchester, we design and build carefully managed extensions that feel seamless, considered and built to last.

Every project begins with understanding how you live now and how you want your home to work in the future.

Creating More Room for Life

Extending your home is a significant decision. It requires structural expertise, detailed planning and precise execution. Our team combines architectural design, technical knowledge and construction experience to ensure your extension not only looks exceptional but integrates properly with your existing home.

Steelwork, foundations, drainage, rooflines and structural alterations are handled with care and accuracy. Just as importantly, the finishes are delivered to the same exacting standards.

The result is space that feels as though it has always belonged.

Considering an Extension?

You may already have a clear idea of what you need; a larger kitchen, additional bedrooms, a new layout that improves flow. Or you may simply know your current space no longer works for your lifestyle.

Our friendly and knowledgeable architectural design team will guide you through feasibility, proportions, planning constraints and structural requirements, offering honest advice at every stage. If something can be improved, we’ll say so. If something won’t work, we’ll explain why and work with you to find an alternative.

We know from over 40 years of experience that clear guidance at the outset prevents costly mistakes later.

Managing the Complexity

Extensions are usually completed while families continue living in their homes; most people won’t have the option to relocate elsewhere temporarily. Much of the anxiety around taking on an extension focuses on the disruption that it will cause to day to day life in the short term.

Large scale projects like these require careful planning and disciplined project management. To minimise stress for our customers we establish clear timelines, protect existing areas, maintain tidy and organised sites, and keep communication consistent throughout. One accountable team oversees the entire process, coordinating every trade and ensuring work progresses smoothly and safely.

You’ll never be left left chasing updates or managing contractors yourself.

Built Around Long-Term Value

A well-designed extension should enhance daily life now while strengthening the long-term value of your property. We approach every project with that responsibility in mind. Structural work is carefully calculated and precisely executed, materials are selected for durability as well as appearance, and new spaces are integrated seamlessly with the existing building so they feel cohesive and permanent.

Quality is not assumed, it is managed. Each stage of the build is professionally overseen, with careful attention paid to foundations, steelwork, brick matching, rooflines and finishes. Nothing is rushed and no detail is overlooked, because what sits behind the walls is just as important as what you see on the surface.

Our clients trust us with substantial, carefully considered projects across Cheshire and Greater Manchester. Many return to us for second and third phases of work, a reflection of the standards we maintain and the relationships we build along the way.

Fixed, Transparent Pricing

Significant building work demands financial clarity. Before construction begins, your project is fully specified and agreed in writing with a fixed price. You know what is included, how the project will progress and what to expect.

No ambiguity. No hidden costs. Just careful planning and clear accountability.

Planning a Significant Extension?

We’re best suited to homeowners undertaking considered, high-investment projects who value quality, structure and long-term results.

House Extension FAQs

How do I begin the process of designing a house extension?

The first step is a detailed consultation where we assess your existing property, discuss how you want the space to function, and explore what is structurally and practically achievable. We provide clear guidance on feasibility, proportions and budget before moving into carefully developed design plans.

What types of house extensions are available in Manchester and Cheshire?

Extensions vary depending on your property and goals. Options typically include single-storey, double-storey, rear and side extensions, as well as more extensive structural reconfigurations. The right approach depends on space, planning constraints and how you want your home to work long term, we’ll advise you honestly on what will deliver the best outcome.

How long does a house extension take?

Timescales depend on size, complexity and structural requirements. A well-planned extension commonly takes several months, while larger or more complex projects may take longer. At the outset, we provide a realistic schedule so you understand how the build will progress.

Will I need planning permission?

Some extensions fall within permitted development, while others require full planning approval. We manage all necessary applications, drawings and liaison with local authorities on your behalf, ensuring compliance and clarity throughout.

How should I budget for a house extension?

A considered extension involves design development, structural calculations, construction costs and finishes. Before work begins, we provide a detailed fixed price based on an agreed scope of works, so you know exactly what is included and what to expect financially.

How will a house extension impact my daily life?

Living through building work requires planning and organisation. We establish clear timelines, protect existing areas of your home and maintain tidy, well-managed sites. Communication remains consistent throughout, and where necessary, we help you plan temporary arrangements such as temporary kitchens to minimise disruption.

Do house extensions add value

A carefully designed and professionally built extension can significantly enhance both usability and long-term property value. Beyond resale, the greatest return is often in improved layout, light and functionality making your home work better for you for years to come.
