Home Extension

At Lancashire Double Glazing, we specialise in creating beautiful and practical single-storey home extensions that stand the test of time. Our extensions are designed to blend seamlessly with your existing home, enhancing its character and functionality.

Kitchen extensions and open-plan living spaces are increasingly popular for those seeking larger entertaining areas. If you envision a spacious, open-plan dining kitchen but prefer not to move, a kitchen extension might be the perfect solution for you.

Not only do these extensions provide the extra room you need, but they also significantly increase your home’s value. By planning carefully, you can make your property more appealing to potential buyers in the future. Our kitchen extensions exemplify the idea that the heart of a home is not just for cooking; it’s a place to gather, share, and create lasting memories.

At Lancashire Double Glazing, we are passionate about helping you design your ideal living space from the ground up. You have the opportunity to customise every detail, ensuring that your extension reflects your unique style and needs. Contact us today to turn your dream extension into a reality!

A professionally designed home extension is one of the most effective ways to transform your property. Whether you need a larger kitchen for busy family life, an open‑plan living area filled with natural light, an additional bedroom, a dedicated home office, or extra entertaining space, a well‑planned extension can completely change how your home works for you.

At Lancashire Double Glazing, we deliver fully managed, family‑friendly home extensions across Lancashire and the Northwest. Our approach combines careful planning, honest pricing, and complete turnkey project management – giving you a smooth, stress‑free experience from start to finish.

Every family is different, which is why every home extension we build is carefully tailored to suit your individual needs and lifestyle.
Whether you’re looking to create an open‑plan kitchen diner for busy mornings and family gatherings, a larger living room to relax together, a garden‑facing dining space filled with natural light, an additional bedroom, a playroom or teenage retreat, a dedicated home office, or a practical utility room, we design spaces that truly work for modern living.
Our focus is always on creating environments that feel natural, bright, and highly functional – enhancing everyday family life while adding long‑term value to your property.

We do far more than build walls and fit windows.

Our turnkey home extension service means we manage every technical, structural, and compliance aspect of your project – so you do not have to coordinate multiple contractors yourself.

Our managed service includes:

• Structural engineer calculations
• SAP and U‑value assessments
• Building Control coordination
• Council submissions (where required)
• Groundworks and drainage
• Structural steelwork
• Electrical planning
• Roof system specification
• Glazing design and installation

By packaging structural design, glazing systems, roofing, and compliance together, we reduce the risk of delays, unexpected costs, or mid‑project changes.

You deal with one experienced team from design through to completion.

A home extension is a significant investment – and transparency matters.

From the outset, we ensure all major structural and practical elements are considered within your quotation, including:

• Groundworks
• Drainage
• Structural steel
• Electrical requirements
• Roofing systems
• Glazing and door installations

We clearly confirm whether your project is fixed price and detail any provisional sums in full. This reduces surprises and ensures you understand exactly what is included before work begins.

As a family‑run company, we believe careful planning leads to better builds.

Many home extensions can be built under Permitted Development (PD) rights, depending on property type and size.

Typical guidelines include:

• Rear extensions up to:
  • 4 metres for detached homes
  • 3 metres for semi‑detached or terraced homes
• Under the Prior Approval scheme:
  • Up to 8 metres for detached homes
  • Up to 6 metres for semi‑detached or terraced homes
• Maximum overall height of 4 metres
• Cannot cover more than 50% of the land around the original house

Permitted Development does not apply to flats, maisonettes, listed buildings, or certain conservation areas.

We advise you on whether planning permission is required and manage submissions where necessary, ensuring your project stays compliant and on track.

The right roof and design choices play a crucial role in enhancing natural light, comfort, energy efficiency, and overall visual appeal.
We offer a wide range of options to suit your home and style, including traditional tiled roofs, lightweight replica tile systems, solid insulated roof panels, elegant roof lantern systems, mixed solid and glazed designs, and large aluminium sliding or bi‑fold doors that create seamless connections to your garden.

Modern home extensions often incorporate warm roof systems, expansive glazed openings, and feature roof lanterns, all of which require precise structural and thermal calculations.
Our experienced team manages these technical elements professionally, ensuring your extension performs beautifully as well as looks impressive.

A well‑designed home extension not only increases your usable living space but also improves energy efficiency, enhances natural light, modernises your layout, and adds long‑term property value. Whether you are creating room for a growing family or planning for future resale, a professionally managed extension represents a smart investment in both your lifestyle and your home’s overall worth.
