“I used Le Roi and his team for my extension project. Le Roi helped us with the overall design of our extension right down to the details of where sockets, spot lights and light switches would be located and took our project from the initial drawings and designs all the way through to managing the build and making sure that everything was signed off correctly in regards to planning permission, structural calculations and building control. I would recommend Le Roi and his team to anyone who is looking for a smooth and efficient building project. Thanks again Le Roi!!”

Average rating: 5 out of 5 stars28 June 2023
“We have done a number of project over the course of 5 years with Artifex on residential and commercial projects. They have been great to work with in all roles of the company, Ed has been enthusiastic and passionate about all of our projects throughout despite the differing work, the Artifex team are professional on site and work tidy and efficiently and any sub contracts have been easy to work with. The key strength of Artifex is the quality of the work and attention to detail which has been a consistent over the last 5 years. The work is always completed within a sensible timeframe and within budget. As a surveyor / developer they have made it very easy for me to work with them and I would highly recommend to anyone.”
Gresford Architects Ltd
House Extension Professionals in Northamptonshire
Average rating: 5 out of 5 stars2 February 2022
“Tom and his team have been outstanding and so professional from day one. They take the time and care to explain all processes step by step including fee proposals and looking at time lines. They have listened to us patiently and respectfully even when I’ve come put with some crazy ideas but found a solution that was not only pleasing but better than I could have imagined. Will has been brilliant at responding efficiently and immediately no matter how silly the questions they may be, making the team very approachable. He has worked and listened to us and asked all the right questions to find a design that suits our needs but is practical. Both Tom and Will at each point have also kept us advised regarding budget at each step and clear about how the changes we want to make may impact that but more importantly rather than dismissing these ideas, looked for solutions and compromises where necessary which we would be happy with while trying to stay on target budget. We can not recommend them highly enough and have also used the team on much larger projects.”
Claire Halstead Interiors
House Extension Professionals in Northamptonshire
Average rating: 5 out of 5 stars5 March 2024
“It has been an absolute pleasure to have Claire working on our renovation project. She has a natural talent in interior design and has guided us step by step through the process. Claire instinctively reads a space to identify how to benefit from it the most. We were genuinely unsure of how to make our tired 1920's cottage work for us, but with Claire's calm professional approach and well thought out vision we could then see the potential within our home. A true eureka moment! As well as taking a practical approach to her work Claire is very much a creative at heart, this shows in her designs and navigation of any hiccups which may come along the way. We would highly recommend Claire Halstead Interiors for taking any space to the next level, and have some fun whist doing it!”

R LANGE CONSTRUCTION LTD
House Extension Professionals in Northamptonshire
Average rating: 5 out of 5 stars6 April 2021
“"Exceptional build completed on budget in extraordinarily challenging times. Ryan and his team provided full service from input into original architectural drawings to handing over the keys. Despite the difficulties of Covid, the project was completed painlessly and to the highest standard. Ryan offered considerable support and advice to help us through the hundreds of micro decisions that ensured we got the perfect modern finish we required. Our house was a largely untouched 1970s ugly house which has been transformed into a Scandi minimalist living space for three generations. We have no hesitation in recommending Ryan."”

“We had a garage conversion/alterations done by Cubit contracts last year. I would highly recommend them, Lewis in particular was extremely knowledgeable, professional and courteous, he went above and beyond to get jobs done to suite our specific requirements.

Average rating: 5 out of 5 stars4 March 2022
“The professional and construction team at the Site were instrumental in delivering our project at Downton Farm. The design and build team offered a turnkey solution from planning right through to marketing and handover. The quality of the build was incredibly high and all the properties exceeded asking price on disposal. This unique and flexible service offered by The Site Projects made delivering this development far easier than it would have been had we approached this scheme from a more traditional route. We are underway on two more schemes already. Don't delay, get in touch!”

Design and Build Company FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Northamptonshire.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
