“Alicia helped me redesign my leaving room and it was amazing! She truly understood the emotions I wanted to achieve with the new interior and made my leaving room my perfect space! Working with Alicia was fantastic, she was creative and quickly put my random ideas into a cohesive plan. She simply understood me and my house :-)”

“We are pleased with the fantastic outcome of our refurbishment! Atudori Construction Services proved to be committed and reliable, with a professional touch they finished in time all the work(electricity, tiling, and decorating). Great communication skills-we only had to talk with 1 person which makes everything easier. We highly recommend Atudori CS !”

Average rating: 5 out of 5 stars2 October 2023
“Firstly, I would like to thank Flavio Da Costa, Murilo (project manager) & his team for their work on our 3 bed property – they were amazing! Throughout the 4 month process, the work was progressing faster than schedule, as well as keeping to a very high standard. We had undertaken a whole house refurbishment - which includes but not limited to; wall demolishment’s, full house electrical rewiring, flooring, door replacements, decorating, bathroom, heaters, skirtings, stair bannister, kitchen – basically everything possible! Flavio & his team not only performed the work we requested, but it is evident they care about their work, and their work is not ‘just a job’. We were kept well informed throughout the process; communication was clear, fair and prompt. Flavio & his team were recommended to us from a friend, and I can see why becuase we are very happy with the entire process and final output – we would 100% recommend this company for any jobs you may have (big or small!).”

“We are delighted to share our wonderful experience with The Finns Group. They transformed our master bedroom into a bedside nursery, and the results exceeded our expectations. The attention to detail, creativity, and craftsmanship they brought to the project was truly remarkable. Their dedication to understanding our vision and translating it into a beautiful, functional space for our newborn was truly extraordinary and we couldn’t be happier. We highly recommend The Finns Group. Their talent and passion for their craft shone through from start to finish.”

Average rating: 5 out of 5 stars26 January 2021
“James and his team were incredibly professional throughout the project. The design ideas and the building work involved to “make them happen” were exemplary. The management and communication of expectations and price as we uncovered challenging issues with the cottage were also very clear and easy to understand from a layman perspective. With reference to COVID, the team were always very respectful of the necessary working practices and despite materials being somewhat scarce there were no delays to the completion of the project.”

Compass Design & Build Ltd
House Extension Professionals in Letchworth Garden City, Hertfordshire
Average rating: 5 out of 5 stars2 May 2018
“'We engaged Compass Design and Build to carry out a double-storey side extension and full refurbishment of our house. From as early as the initial quote, they produced detailed plans, costs and timings with clear thought about the whole process. The work involved liaising with many different third parties - security companies, bi-fold door companies, landscapers, interior designers etc and these relationships were managed very efficiently; with timings constantly adhered to. The team were consistent and easy to work with.'”
Defined Builds Limited

Average rating: 5 out of 5 stars5 November 2018
“James did a great job for us in our flat, replacing all the internal doors and installing associated door furniture etc - laying a v. complex parquet floor amazingly well and also levelling the joists underneath as well as installing extra insulation beneath the floor. He also built us two sets of floor to ceiling wardrobes which turned out brilliantly and he also built us alcove units and cupboards in our sitting room. James is great to deal with and his workmanship is top quality. We can't recommend him highly enough and will definitely use him again in the future.”

“Keith Barke did a great job for us, converting a garage into a living room and a small bedroom into a study. The major job was the conversion and though we knew roughly what we wanted, Keith came up with excellent ideas on such things as the heating and lighting that really improved the final design and functionality of the room. He also liaised with the council on the required building regulations. The smaller room is an awkward shape but, again, Keith came up with a smart solution involving a bespoke desk that has made the best use of the space - it wasn't something we could have visualised without his expertise. Very friendly and attentive service - not just Keith but all of his team - and the whole job was completed on time and on budget. Suffice to say, we're very pleased, and we're just about to use the firm again on another room. Highly recommended.”

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 Letchworth Garden City.

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.
