“Build Team have just completed the design phase of my kitchen side return extension project and we have planning permission. I'm very happy with my final plans and the whole process.

“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 hired CELLI Property Care for our loft conversion, and I can honestly say that they were just more then we expected. It was our first time doing something this big to our house so we needed someone with experience that knew exactly what would go into a project like this. They did a fantastic job at walking us through every part of the project and they guaranteed that they will keep us in the loop throughout the whole process. The guys were really hardworking, tidy and polite. They would clean at the end of each working day, and they did everything possible not to disturb us. The price wasn't the cheapest of all the quotes we've received, but Celino was by far the most knowledgeable and patient estimator that came to visit us. Overall we are very happy with the job and we would recommend CELLI Property Care to anyone looking to hire a responsible, fair and hardworking contractor. Emma Hughes”

“Sam had a vision right from the start. He came up with an ideal solution for my bedroom, which was something I'd never even considered. His designed sealed the deal and I went ahead with the new bedroom order and am very happy with the result. I would happily recommend Sam to anybody needing a bespoke design.”

Plus Rooms
House Extension Professionals in Haringey, Greater London
Average rating: 4 out of 5 stars12 May 2015
“Living through a kitchen extension on a terraced London house isn't fun. We both work full-time and have two children at school so returning at the end of each day to the property once works had commenced could be a little stressful; but PlusRooms protected our downstairs areas, created a temporary kitchen for us and were really considerate of the fact we were living through the works. They project managed the whole thing right from design, costing, adjustments, planning, build scheduling, (prompting us what to buy and when), right through the build - and we couldn't be more delighted with our new space. Living through building works is unpleasant but was made less so with Robbie and James' support and professionalism. We had the odd snagging that needed resolving at the end of the job, which you would always expect, so we are more than happy to recommend PlusRooms and may be using them again next year!”

“To set the scene : we are mid-way through construction, to renovate & extend of our Victorian terrace in East London. We've had Seán and Stephen Ltd as our architects for 18 months so far. My wife and I are complete novices to design & construction, and Seán and Stephen have expertly and supportively guided us through each stage, enabling us to really enjoy every part of creating our new home. I would happily recommend this professional practice to family and friends. They were great at helping to bring some of our own design preferences to life using plans, 3D models, and interactive virtual room design tools. But they also have challenged our thinking too, leading us to add in a number of amazing and creative features that we would never otherwise have considered. Seán and Stephen created an extremely thorough and professional Design & Access Statement to help explain our project to the local planners. As a direct result of the quality of S&S’s planning pack our application (which proposed various potentially contentious items such as a basement, lightwell, and dormer) was approved without a single significant amendment. Since the contractor began the works Seán and Stephen have project managed every aspect of the construction programme, providing us with detailed weekly updates and explaining everything to us in layman’s terms. They consistently fight our corner with the contractor on a number of technical and cost-related issues which gives us real confidence that the project is in safe hands. So far we have enjoyed a stress-free project thanks to their project management skills”

“It is with huge pleasure that we provide a high recommendation for Paragon. They added a master bedroom, en-suite, walk in cupboard, loft conversation and rear extension to our existing home. From the beginning we felt very comfortable with Paragon's approach. They really listened to our brief and provided excellent advice. The final design was outstanding. The management of the design, consent, contract and construction process was seamless and stress-free with clear instructions from the team at Paragon and very little effort required from us. Their professionalism shows in management, quality of work and customer service. Our experience has been an extremely very positive one. Working with a team that is accommodating and sensitive to our needs. What a concept!”

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 Haringey.

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.
