“We worked with Chris on our extension and loft project, and throughout the process he was incredibly professional, responsive and supportive. Unfortunately, we encountered significant issues with our construction company, which caused delays and complications that were completely outside of Chris's control. Despite this, Chris consistently went above and beyond to help us navigate the situation, providing advice, answering questions promptly, and doing everything he could to keep the project moving forward. His communication was excellent from start to finish, and his patience and willingness to assist during a particularly stressful period were greatly appreciated. The drawings and planning work were completed to a high standard, and he always took the time to explain options and address any concerns we had. I wouldn't hesitate to recommend Chris to anyone looking for an architect who is knowledgeable, reliable, and genuinely invested in helping their clients achieve the best possible outcome.”

“We are currently working with Atelier on a complete house renovation / extension project and they have been absolutely fantastic. We contacted Atelier shortly after our offer was accepted on the property to discuss how best to get started. We have 2 young children so were quite daunted by the idea of a project that dragged on / took years to complete. Within just 4 weeks Angie / Dom came up with a concept design for the whole house, lined up a great contractor who was able to meet our (very ambitious!) timeframes and helped us source various elements for the project. We are now 5 weeks into our renovation project and are due to be moving into the property in just 3 weeks time with the extension to follow shortly. All this would have been impossible without Atelier and we can’t recommend them highly enough.”

“Sean helped us draw up plans for a loft and house extension. We found him to be professional yet down to earth, and very forthcoming in what he believed to be possible and what would not be possible right from the start. He also brought lots of ideas to the project which we hadn't though of, and a lot of local knowledge with regards to rules and regulations in our part of the County. I would highly recommend Sean to anyone looking for an honest, professional architect to help them with a project.”

Architect or Architectural Designer 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 Brighton.

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.
