“Super professional and really high quality work. Transparent pricing and very responsive to any questions or concerns. Worked hard to catch up on any delays (e.g. the inevitable late windows), and kept us informed of progress. A really nice team - without exception everyone who worked on the project was friendly, considerate and incredibly hard-working.”

“After considering 4 other contractors we selected Ryan's Decorators on the basis of previous projects, references and their clear understanding of the project. Do not be fooled by the company name - they do far more than just decorating! In summary Ryan's Decorators offer and deliver a first class service at a very competitive price. I would not hesitate to recommend this company.”

“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”

“A company with a conscience! Kal, Vladi and the team at KMI were committed to getting it right for us from the start to the end. Excellent workmanship and attention to detail and they were professional and reliable during the 6-week project. I am looking forward to calling on the team again for building and decorating works in the future.”

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 Balham.

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.
