Services
Loft conversions
Our bespoke loft conversions transform unused attic spaces into functional living areas. With expert design and construction, we create additional bedrooms, bathrooms, or home offices that seamlessly integrate with your existing property. Every conversion includes structural calculations, building regulation compliance, and a 10-year warranty for complete peace of mind.
Design services
Our architectural team creates tailored designs optimising your loft's potential. We consider head height, structural requirements, and your specific needs to develop practical layouts. The service includes 3D visualisations, planning permission applications, and detailed construction drawings to ensure perfect project execution.
Construction management
We oversee every aspect of the conversion process with dedicated site supervisors. Our in-house tradespeople handle carpentry, plumbing, electrics, and plastering to maintain quality standards. The service includes material sourcing, scheduling, and daily progress monitoring to ensure timely completion within agreed specifications.
Completion works
Our comprehensive service includes all finishing elements required for habitable spaces. We install insulation, flooring, lighting, and staircase solutions while ensuring proper ventilation. The final stage involves building control inspections, thorough cleaning, and handover of warranty documentation and maintenance guidelines.
Free surveys
We offer complimentary property assessments to determine conversion feasibility. Our designers evaluate structural capacity, headroom, and access points during home visits. The survey includes preliminary design suggestions, planning considerations, and a no-obligation quotation for the proposed works.

Happy customers, would recommend to a friend
We were very happy with Loft Plan and would recommended them to a friend. From start to finish the whole process was very smooth, the works went over the Christmas Period so there was a little pause in the works but this was understandable and Loft Plan made sure that they finished at the end of a stage so everything was left tidy while Christmas occurred.

There was a little delay getting back to it after Christmas as the stairs weren't quite ready, but once they were ready all the next stages happened quickly and efficiently.

Bob was great, made sure everything was done efficiently and kept all the different teams on target. We are extremely happy with our loft conversion and cant to start using it.

We have just had our loft conversion completed through Loftplan and we are very happy with the outcome. As a family, we desperately needed more space and were left with the dilemma - move or improve. We chose to improve and we don't regret that decision one bit. From start to finish, in what was a large project to us as a family, the process was made easy. From the initial consultation with Nic, we were guided through the project and kept well informed by Nicola. Wed like to thank all the team for all your hard work, the outcome with an additional two bedrooms and en-suite has made a huge difference to all of us.

More space, bedrooms, storage, everything we needed. Big thanks to Warren for managing the project, Josh & Riley for all their hard work in the build (amazing job), Shaun who was brilliant, Richie (stairs), Ron & Graham (electricians), the plumbers, Craig and Gary (roofers), the scaffolders.. a great team! We wouldn't hesitate in recommending Loftplan to others. A great company to deal with.

Great experience - a seamless system from start to finish. They knew exactly what should go where and listened to our ideas as well. Martin the carpenter and Jake the electrician deserve special mention. We now have 2 extra bedrooms and a bathroom which has enhanced the house hugely. The finishes were all of a high standard- which was brilliant.
