Featured Reviews for House Extension Professionals in Portsmouth, Hampshire

Innovation Construction Design & Build Ltd
House Extension Professionals in Portsmouth, Hampshire
Average rating: 5 out of 5 stars1 December 2022
“Bill and his team were recommended to us by some friends who had work done by the them. We're so pleased that we took their recommendation because from the first time we met Bill, right through the build and onto the completion of the project we have been thoroughly impressed with the professionalism and expertise of himself and his staff. We planned to extend our house at the back and to the side (which we have done) but with advice and suggestions from Bill, who was able to guide us during the whole design process, we have managed to gain so much more from the build than we originally anticipated. Bill reconfigured the layout to allow us to also have space for a downstairs toilet/wet room and also a laundry room. He did all of this without compromising on the other key features we wanted to incorporate into our new kitchen/family room and study area. Bill also suggested installing 5 Bi-Fold doors across the back of the house instead of the planned windows and patio doors and the result is amazing. We now have maximum light and a feeling of space all day long as well as an uninterrupted view of the garden. Everything came in on budget and we're confident that no corners were cut to achieve this. I honestly can't recommend Bill and his team highly enough. They are friendly, trustworthy and reliable - exactly what you want when you have strangers working in your home”

Bespoke Living Construction Ltd
House Extension Professionals in Portsmouth, Hampshire
Average rating: 5 out of 5 stars24 May 2019
“The whole experience with Bespoke Living was excellent from start to finish. They were professional from the first time we met and always kept to the timelines they set, including when I would receive the original quotation. I think I was quite a tricky client but they were always polite and patient with my questions. The standard of their work was flawless with incredible attention to detail pointing out issues which I wouldn't have noticed. I chose awkward tiles and difficult grouting but the finished result is exactly as I imagined and I love my new kitchen and bathroom! I have no hesitation in recommending Bespoke Living and if/when I do another project I wouldn't use any other company!”

“It is with huge pleasure that we provide a high recommendation for Paragon. They added a master bedroom, en-suite, walk in cupboard, loft conversation and rear extension to our existing home. From the beginning we felt very comfortable with Paragon's approach. They really listened to our brief and provided excellent advice. The final design was outstanding. The management of the design, consent, contract and construction process was seamless and stress-free with clear instructions from the team at Paragon and very little effort required from us. Their professionalism shows in management, quality of work and customer service. Our experience has been an extremely very positive one. Working with a team that is accommodating and sensitive to our needs. What a concept!”

“Lee and his team built our extension for us and renovated the ground floor. I wouldn't hesitate to recommend the company to others as we had such a positive experience - highly professional and good at keeping us in the loop as the work progressed. The end result exceeded expectations and was finished to a high quality - just make sure you keep the biscuit tin well stocked! We are thrilled with our new home, thank you Stone Red!”

Average rating: 5 out of 5 stars18 February 2021
“I've used J White Developments for a number of years. The projects have been varied in size and type but have always been done well and at a reasonable cost. The owner, Josh, has an extensive understanding of the building trade and has been able to advise and recommend solutions for every problem I have given him. He has always kept me informed on costs and timings and comes in on budget unless we agree changes. When he has used sub-contractors he has always overseen their work to make sure it is up to standard. Examples of larger projects: Lifting and re-laying the stone terrace around the property. Replacing a drain that regularly overflowed with a larger capacity one and redesigning soak-away Smaller project examples: Renovating wooden floors, replacing and installing lights for pictures, repairing garden lighting, perimeter fence repairs.”

Builder 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 Portsmouth.

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.
