“CADup Ltd are a friendly and professional company that I would not hesitate to recommend to anyone. I have used CAD UP to produce technical detail drawings for my business since 2010 and have always been happy with the service they provide. The drawings are produced with meticulous detail and are presented clearly. Their costs are reasonable and go out of their way to meet deadlines. I would heartily recommend them to any one looking for architectural or detailed drawings.”

“We hired Sam to help us renovate a very lovely but rundown Victorian home just by the Brighton sea front. It was in desperate need of repairs and was also our first home. Sam and his team are very accommodating to our wants and needs for the home which will double as both a family home and workspace as well 2 holiday lets. It's been a very long and large-scale project and we are very satisfied. Would recommend.”

Brian Hoolahan Architect
House Extension Professionals in West Sussex
Average rating: 5 out of 5 stars14 March 2024
“Brian Hoolahan acted as our principal architect as we embarked on our project to replace our harbour fronted home in Chichester. The location of the property was particularly sensitive as it is situated in an Area of Outstanding Natural Beauty. Our brief was for Brian’s practice to design a family home using traditional materials whilst at the same time satisfying some of the highest environmental standards with respect to energy efficiency and material sourcing - including ground source heating and significant reliance of a sustainably sourced oak structure as an alternative to steel. Further, as a resident of Bosham we very much required that our new home was to be sympathetic towards the local environment, being close to Bosham village and its grade 1 listed Anglican church. Brian led all aspects of the design and planning approval process - which included satisfying the requirements of the District and Parish counsils as well as other authorities, including Chichester Harbour Conservancy. Following planning approval, Brian, through his construction company, Harbour Contractors, project managed the build covering all aspects of compliance and certification addressing architectural matters as they arose. We were delighted in choosing Brian’s organisation for our project and were able to benefit from his many years of professional experience as well as his deep architectural knowledge, having developed many projects throughout West Sussex.”

“Each design that Three|Eleven work on is unique and never formulaic, Rob Beer works creatively to exceed both a clients needs and their vision. We have worked with Rob on a challenging new build in Rottingdean where planning permission was tough to gain and came with incredibly tight restrictions. With constraints on size, this project demanded a creative design to maximise both space and light, whilst also meeting the clients dream of a traditional Arts & Crafts style house. We are currently working with Rob to build a stunning extension on a Victorian house which is also progressing well. It's a pleasure to work with Rob, we receive the detailed plans we need and communication is open and supportive - we really couldn't recommend Three|Eleven more highly.”

“We were very pleased when Karenna Wilford Architects were recommended to us for our cottage extension and refurbishment. Karenna has been like a breath of fresh air to us. She is reliable, professional and very pleasant to work with. She worked closely with us to give us not only just what we wanted but also made valuable suggestions which proved to be a large benefit to the final scheme. KWA project managed all the building works as we had very specific requirements and wanted to use specialised contractors. They were very efficient and KWA kept us well informed of the impact some of the design decisions would have on our budget! We love our new home and can thoroughly recommend Karenna and her team.”

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 West Sussex.

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.
