Smart Home Extensions
Designed Around Your Home
A smart home extension is the modern way to add space to your home. Built faster than a traditional extension, with a fixed timeline and a clear cost, and finished to look like a natural part of the property.
From brick-matched single-storey builds through to timber-clad statement extensions, every project is designed around how you live and what your home needs.


Planning & Building Regulations
We handle all the planning and building regulations for your extension project. From paperwork and permits to liaison with local authorities, we take care of the legal side so you can focus on the build itself.
Our Range
A range of contemporary extension styles designed to create bright, functional living spaces with a seamless connection to your home and garden.

Single-Storey Extensions
Brick-matched extensions designed to look like a natural part of your home. Ideal for kitchens, dining areas and additional living space.

Glazed Extensions
Modern extensions built around large glazing and lantern roofs. Bright, open spaces that connect your home to the garden.

Orangeries
A classic style of extension with solid walls, large windows and a glazed roof. Elegant, light-filled and suited to year-round use.
Built Using Quality Materials
Every extension is built using contemporary materials chosen for both performance and appearance — timber cladding, modern glazing systems, and anthracite aluminium frames. The result is a space that complements your home, performs year-round, and lasts.

FAQs
Do I need planning permission for a home extension?
In many cases, no. Most single-storey extensions fall under permitted development and don’t require planning permission, although larger projects, glazed designs, or homes in conservation areas may need approval. We handle all the planning checks for you, so you’ll know exactly where you stand before any work begins.
How long does a home extension take from start to finish?
Most smart home extensions are completed in 8-14 weeks, depending on size, complexity and finish. Single-storey brick-matched extensions are usually the quickest, while glazed extensions and orangeries take a little longer. We’ll confirm a clear timeline before work begins and stick to it.
What's the difference between the extension types?
A single-storey extension is a brick-matched build designed to look like a natural part of your home — usually the most accessible option. A glazed extension uses large windows and a glazed roof to create a bright, open space. An orangery sits between the two, with solid walls and a glazed lantern roof for a more classic feel. The right choice depends on your home, your budget, and how you want to use the space.
How much does an extension cost?
Smart home extensions typically range from around £30,000 for a smaller single-storey build through to £150,000+ for larger, glazing-led projects. Cost depends on size, materials, glazing specification and finish. We’ll provide a clear quote with no hidden costs after your initial consultation.
Will an extension add value to my home?
Yes — a well-designed extension generally adds value to your property, often more than the cost of the build itself. The biggest gains usually come from extensions that add usable living space, improve natural light, and connect the home to the garden. Local market conditions also play a part, and we can advise on what’s likely to deliver the best return for your area.
