“They're a small yet highly experienced architects practice. You really get the sense that your project is being treated as a top priority. It was a complicated project and the council was proving difficult but they never lost focus and in the end we got everything we'd been aiming for. The interiors they designed look fantastic and they managed to deliver them in budget which I'm led to believe is pretty much unheard of. Great results and a very friendly team to work with. Wouldn't hesitate to recommend.”

“We really are delighted with the outcome, the house couldn't look or feel more different! Whilst sitting having breakfast this morning, we remarked how amazing it was to have such a panoramic view of the beach.”

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 Southampton.

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.
