Why Consider Professional Barn Conversion?
A barn conversion combines the distinct style of a barn with modern-day amenities. Every barn offers a new opportunity to repurpose an underutilised space into a home bursting with personal flair and style. Practical in every sense, barn conversions serve both as an expansion of living space and as a long-term investment. At Paramountbuilt, we provide detailed planning and structural precision, finishing high-quality historic buildings into stunning, functional homes.

Testimonials
Paramountbuilt 36 Google reviews Elvin Turner2025-05-23 Great consultation! Lielis Andrews2025-05-23 Quick and efficient service. Would use again. Timely visit to property and survey provided within 5 working days. Excellent communication from start to finish. SALINDER PATEL2025-05-23 Great service, did everything they could to ensure i got this within the timeline. Customer service was 5 stars, kept me updated all through the process. Definitely be using them again. Deborah Dunkley2025-05-21 I chose this company after reading their trust pilot reviews. Initially I spoke to Amber who was very knowledgeable on the telephone and was able to speak to me in technical terms which was reassuring. A survey was arranged and carried out for the approaching weekend. Aslan carried out my Survey and he was thorough. I have now instructed them to go ahead and submit my plans for building regs and I know my project is in good hands. Yasemin A2025-05-09 I recently used paramountbuilt for a structural survey on a property I was purchasing, and I couldn’t be happier with their service. From start to finish, the team was professional and thorough. They provided a detailed report that was easy to understand, highlighting all the key findings and offering clear recommendations. Their expertise and attention to detail gave me complete peace of mind during the buying process. Valentina Ljubchinskaja2025-05-08 I applied for a house extension with Paramaunt Build and submitted a planning permission application through the council. At the start, Sophie and Zoe were very nice and helpful. Later, Sumet came on board and did a great job with the painting. I had a few amendments, including some that came after the application had already been submitted, but the team was always accommodating and made the changes as requested — they were truly kind and supportive throughout. Amber helped speed up the process, and I was told that hopefully by 8th May, the council would approve the project. And today, on 8th May, Amber called with the great news — my application has been approved! Right now, we're halfway through the process with the company, and the next steps will be with the building control department. I hope that part goes just as smoothly and efficiently. Once the whole project is completed, I’ll be happy to leave a detailed review. Thank you, Paramaunt Build team!
FAQ’S
In London, most of the barn conversions will require planning permission, particularly if the structure does not contain zoning for residential use. In some circumstances, prior approval could apply, but it is dependent on the building and its city.
When done properly, barn conversions can be remarkably energy-efficient, especially when proper insulation, modern heating systems, and sustainable materials are used. Energy costs can greatly be reduced by installing double glazing, underfloor heating, and solar panels.
Yes, a barn conversion can be extended if it gets the planning permission and meets the building regulations. These alterations can be helpful in expanding the barn’s space and overall functionality.
You can turn your barn into as many functional rooms as you want. As long as you have the right structural design in place, it is easy to achieve.
For barn conversion the best flooring is polished concrete or engineered wood. Both are durable, stylish and rustic, while also serving as ideal complements to underfloor heating. Most importantly, they preserve the character of the space.
