Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

What is a house extension?
A house extension is a significant home improvement project that involves adding extra space to your existing property. This can be achieved by extending the structure outwards or upwards, creating additional rooms or expanding existing ones. House extensions can range from small single-room additions to large multi-room projects that completely transform the layout and functionality of your home. Common types of extensions include:
- Single-Storey Extensions: Ideal for expanding living areas such as kitchens, dining rooms, or living rooms.
- Double-Storey Extensions: Add multiple rooms and increase overall living space without sacrificing garden area.
- Loft Conversions: Make the most of unused attic space to create extra bedrooms, offices, or playrooms.
- Basement Conversions: Convert existing basements into habitable spaces for entertainment, storage, or additional bedrooms.
- Garage Conversions: Transform your garage into a functional living space, such as a guest room, home office, or gym.
Cost of a house extension
The cost of a house extension varies widely based on several factors, including the size and type of extension, the materials used, and the complexity of the project. Here are some general cost estimates to help you plan your budget:
Factors Influencing Costs
- Size of the Extension: Larger extensions require more materials and labour, increasing the overall cost.
- Type of Extension: Different types of extensions (single-storey, double-storey, loft conversion) have different cost implications.
- Materials Used: The choice of materials for walls, flooring, roofing, and finishes can significantly impact the cost.
- Location: Costs can vary based on your location, with projects in urban areas typically costing more due to higher labour rates and material costs.
- Complexity: The complexity of the design and any structural changes required can increase costs. Unique architectural features, custom fittings, and intricate designs will add to the overall expense.
Average Cost Estimates
- Single-Storey Extension: £1,200 to £1,800 per square metre.
- Double-Storey Extension: £1,500 to £2,500 per square metre.
- Loft Conversion: £1,000 to £2,500 per square metre.
- Basement Conversion: £2,000 to £3,000 per square metre.
- Garage Conversion: £5,000 to £20,000, depending on size and specifications.
These estimates include basic construction costs but may not cover additional expenses such as planning permission, architectural fees, and interior finishes.
What kinds of tradespeople do I need for a home extension?
A successful house extension project requires the expertise of various tradespeople. Here are the key professionals you will likely need:
- Architects and Designers: To create the plans and designs for your extension, ensuring it meets your needs and complies with local regulations.
- Builders: To handle the construction work, including laying foundations, building walls, and roofing.
- Electricians: For all electrical installations, including wiring, lighting, and power outlets.
- Plumbers: To install and connect plumbing systems for kitchens, bathrooms, and any other water-related needs.
- Carpenters: For structural woodwork, custom fittings, and cabinetry.
- Plasterers: To finish walls and ceilings, ensuring a smooth, professional look.
- Painters and Decorators: To add the finishing touches, making your new space aesthetically pleasing.
- Flooring Fitters: To install flooring that complements the rest of your home.
- Roofers: If your extension involves roof alterations or new roofing.
- Surveyors: To assess the site, check the structural integrity, and ensure the project meets all building regulations.
Other house extension FAQs
Do I Need Planning Permission to Extend My House?
In many cases, house extensions require planning permission from your local council. However, some extensions may fall under Permitted Development Rights, which allow for certain types of extensions without the need for formal permission. It’s essential to check with your local planning authority to determine the requirements for your project.
Will an Extension Add a Lot of Value to My Home?
A well-designed and executed extension can significantly increase the value of your home. Extensions that add additional bedrooms, bathrooms, or improve the overall functionality and aesthetics of the property tend to offer the highest return on investment.
How Long Does an Extension Take?
The duration of a house extension project depends on the size and complexity of the work. On average, a single-storey extension might take around 3 to 6 months to complete, while more extensive projects, such as double-storey extensions or loft conversions, can take 6 to 12 months or longer. This timeline includes planning, design, construction, and finishing phases

Dan is a force of nature, as anyone who’s met him will agree. He and his team were always dedicated, hard-working and good natured. I would recommend Dan and his team to anyone, especially for a big renovation project like this, which involves working with other parties, such as structural engineers, kitchen designers and installers, as he works with them and takes away most of the pain. The quality of the work is excellent and he always came back to complete the snag list (even 3x for our thresholds).
We are a very dynamic and innovative company; looking to grow and offer all our clients nothing but the best quality work and advice on their projects. In our company nothing leaves us more satisfied than to see the smiles of our clients on a job well done and to see that we were able to materialise their vision of the job.
Great service, professional and friendly. Quick to respond to messages. I will use again.
Very happy with the work Mosaic did. They did 2 bathroom makeovers, they were let down by a tile supplier which delayed our timetable but in general the team were good to work with, focussed, and listened to what we wanted. Also very helpful on design, selection of materials, and adjusting for problems discovered when ripping out the old bathrooms. I would be happy to recommend and use them again.

Ross did a great job laying the patio and installing a shed base. He immediately identified the differing levels my garden had and was able to suggest ideas to maintain relatively level access to my property. Ross arrived for the quotation as agreed and the work was started and finished promptly. He removed all the waste from the project and I'm really pleased with the outcome of the work.

Hi my name is Tom I’ve been plastering for 20 years. I provide a clean helpful service and i do my up most to meet customers requirements
Tom came to skim my son's ceiling but because it had old artex and very uneven he decided to put a false ceiling in, board that and then skim it. Tom is a really friendly guy, kept showing me where he was up to in the job and was very tidy and did a great overall job at a good price. Wouldn't hesitate to use Tom again or recommend to friends and family.
HEX360 was founded in 2015 by Craig Lewis with the solid foundation that a degree in construction management provides. Before launching HEX360, Craig’s former life saw him working at Princess Yachts, where he founded his skills and acquired his particular attention to detail – but if you’ve reached this page, you probably aren’t interested in hearing Craig’s life story… you’re really interested in finding out what makes HEX360 different to all the other construction companies out there. So read on and discover our difference. Working with most construction companies can feel a bit like finding your way in the dark – you just don’t know where to go to get the information you need. The stereotypical construction company that makes matters so confusing and complicated that everything they say goes over your head is, unfortunately, not just a myth. They’re out there, and they’re confusing clients as we speak. So, it’s no wonder that so many people put off their project or come to a grinding halt partway through – after all, it can all feel just too overwhelming. Luckily, HEX360 is here to change your perceptions and prove that not all construction companies are the same. We’re dedicated to working with you, not for you, and that means taking a collaborative approach right from the get-go. With our 8-step process, we’ll clearly outline every stage of your project so you won’t feel overwhelmed, and thanks to our use of in-house project management software, you’ll have complete transparency for every aspect of your project. We are committed to flexibility, accessibility, and approachability so your project can run smoothly, whether you’re updating your kitchen, renovating or extending your entire home or developing a large commercial property. You’re more than a number on a spreadsheet to us, and we never bite off more than we can chew. Our attention and efforts are solely dedicated towards you and your project during your time with us. Unlike with some construction companies, once we begin work on your project we don’t simply move on to our next. We provide industry leading account management during the full life cycle of the project, meaning you aren’t forgotten about once you sign on the dotted line.
