Featured Reviews for House Extension Professionals in Southfields, Greater London

ASJ Design
House Extension Professionals in Southfields, Greater London
Average rating: 5 out of 5 stars1 December 2023
“Genuinely worth their weight in gold. We’ve used ASJ from an interior architectural view on two projects now and on both they’ve nailed it. Their vision to move walls, doors, windows to make the best of the space is spot on and they have a really really good understanding of how space is used which is so important in getting the design right. Can’t recommend enough as you’ll probably have to live with the layout for years.”

“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. My designer was very professional, courteous and helpful. He kept me informed throughout the process, gave good advice and listened to my ideas and concerns.”

“We had our bathroom redone last year by J'Leo Svue. We are extremely pleased with everything, from the initial design phase to the work, to the follow up after. It has now been a year and the bathroom still looks as good as new.”

Average rating: 5 out of 5 stars18 February 2019
“The most efficient and friendly staff, highly professional team that can execute your kitchen dreams and desires to an exact specification! The expertise that the team had from the inception with the detailed drawings with great design ideas and 3D visuals created by Sonya, and the level of detail from the installation manager Avtar who was on site during the process and the complete knowledge of every aspect of a kitchen from appliances, accessories, colour schemes and materials and the utilization of space from the directors Ajit and Sukh gave us clear confidence in their work and passion for the job and service provided. They were extremely personable, warm, friendly and charming and a complete joy to have been serviced by. The finished product has been complimented by every guest and is now clearly the highlight of our home. Would highly recommend to anyone looking for a great quality kitchen with fantastic service to go with it! Our family thank you Design Abode for realising our dream kitchen. One happy customer!”
RB12
House Extension Professionals in Southfields, Greater London
Average rating: 5 out of 5 stars12 February 2020
“We engaged RB12 to deliver a small development project from start to finish. They did the architectural design, planning and permissions followed by project management and then ultimately the interior design. They added a basement level and loft to extend a 3 floor house to 5 floors and then converted it into 3 flats. We now have 3 beautifully designed and well thought out flats. They also supplied all the wood flooring, bathrooms and kitchens. The 3 flats all have their own identity and are by no means a typical boring development you see so often across London. The team super impressed with their knowledge, ideas and friendly yet professional approach. We love the end result.”

“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”

“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”

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 Southfields.

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.
