House Extension Professionals in Swanley, Kent
Average rating: 5 out of 5 stars4 October 2023
“I recently had a house extension/renovation project completed by Grand Alliance Ltd, and I must say, I am absolutely delighted with the result. From start to finish, the team at Grand Alliance Ltd were professional, knowledgeable, and efficient in all aspects of the project. The project involved a significant extension to my home, and I was initially apprehensive about the process. However, the team at Grand Alliance Ltd made sure I was informed and involved throughout the entire process, providing regular updates and answering any questions I had. The quality of work was exceptional, and the team paid close attention to detail to ensure the finished product was of the highest standard. They worked tirelessly to complete the project on time and within budget, which I greatly appreciated. Overall, I would highly recommend Grand Alliance Ltd to anyone looking for a reliable and professional team to handle their house extension/renovation project. They exceeded my expectations, and I am thrilled with the end result. Thank you, Alexey and Grand Alliance Ltd!”

“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”

Asset Project Management
House Extension Professionals in Swanley, Kent
Average rating: 5 out of 5 stars21 November 2023
“Full Refurb, including re-wire, new kitchen, second bathroom, floor levelling. Asset PM did an excellent job of refurbishing & insulating our North London flat. It was badly laid-out and draughty when we bought it for a good price. We decided to invest the saving in a new kitchen, 2nd bathroom, insulation and upgrade to modern electrics. After speaking with various builders we settled on Asset PM because of the combination of Karolina's calm sense of organisation and Robert's extensive previous build experience. The team was easy to deal with and kept us informed as the works progressed (we briefly moved out to family). One of the things that impressed us is that Asset PM honoured their original quote even though costs went up mid-way through the project due to unexpected inflation. They also took care of the certificates and warranties so we are covered for the future. Thanks Robert & Karolina !”

“This building firm is really down to earth. Their projects have been amazing and they not only provide service but they disperse really useful advise such as when we showed them our draft drawings, they suggested improvements which was great as now we have a set of drawings which are amazing especially suggesting interior design features that woud have been harder to implement later on and probably added to the cost, They are also great at purchasing and will get the best deals for you. very easy to talk to and I am looking forward to working with them when our house is being built.

Prestige Build and Management Limited
House Extension Professionals in Swanley, Kent
Average rating: 5 out of 5 stars28 February 2019
“Prestige build and management undertook a complete renovation of our Victorian house in Plumstead last year. We found every member of the team a pleasure to work with. The quality of each of the trades - tiling, electrics, plumbing and building was excellent. The team were interested in achieving the aesthetic we wanted and advised us on some of our slightly naive ideas and material choices to deliver what we wanted. The whole team were clean, efficient trustworthy and personable. The office team were also really efficient and helpful to deal with. They were willing to work with us when we had cash flow issues with the bank which, on a major project, is invaluable for any home owner. We also had significant regulatory issues with a basement conversion and Jay and his team persevered to get the project completed despite the obstacles. I would say that price wise they are on the upper end of the spectrum but you get the quality and service you pay for and for us it was worth every penny.”
My Extension PM Limited

Average rating: 5 out of 5 stars18 October 2022
“MyExtension began my project in May this year and from the outset I found Gosia as project manager and Greg as team leader, approachable, personable and professional, giving advice to a novice like me when needed. The team of builders started work in earnest and worked at pace to get the project to completion in only 4 months. Every time I visited, a new phase was appearing and Gosia was there to explain the next steps and advising me on unexpected issues which ultimately surface when renovating a Victorian property. The team worked hard and were very considerate - my neighbours commented on many occasions about their cleanliness and response to any unforeseen issues which inadvertently affected them. The project has been completed to an extremely high standard bringing my vision for my home to life! I cannot thank the entire team enough for their hard work and due diligence in creating such an exceptional build and finish. If you’re planning on a renovation or build I would highly recommend contacting MyExtension.”

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 Swanley.

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.
