DISCUSS YOUR LOFTLoft types
Loft Conversion Types
The right type depends on your roof, the house and the local planning position. We advise on what suits your property.
Rear dormer
Full-height space added at the back of the roof, suiting many terraced and semi-detached houses.
L-shaped dormer
Two dormers joined over the rear addition, creating the most space on many period terraces.
Hip-to-gable
A hipped roof extended into a vertical gable wall, suited to semi-detached and end-of-terrace houses.
Mansard
The roof slope rebuilt almost vertically for the most internal space, usually needing planning permission.
Rooflight (Velux)
The roof shape kept and rooflights added, where the existing head height allows.
Loft with en-suite
Any conversion type with a bathroom planned in, including drainage and ventilation.

Would 100% recommend
We had a great experience from start to finish. The team delivered an excellent standard of work on our extension, supported by clear planning and effective communication throughout the project. The work was completed on time, within budget, and with minimal disruption. The final result is outstanding, and we are extremely satisfied. We would confidently recommend their services and would use them again in the future.
Would highly recommend Aldas and Angela for their service for our new heating system and new bathroom. Great communication throughout and a real dedication to making sure the finished product was the very best that it could be. I also hugely appreciate them going out of their way with arranging property access for the builders so that we didn’t have any delays before Christmas. Thank you!
Innovate home solutions helped me renovate my flat, and I couldn’t recommend them more. They were very quick and efficient, helping me through the entire process.
We asked Innovate Home Solutions for a design-and-build service for our home modernization and they did a very good job. Quality of work is excellent, though some smaller finishing details took a little longer than expected. Overall very happy.
Innovate Home Solutions transformed our flat with a full internal renovation. Their process was transparent, the timeline was clearly communicated and we felt involved but not stressed. The finish is premium and we love living in the space now.
Absolutely delighted with the work from Innovate Home Solutions. They built a rear extension for us and the results were even better than we hoped. The team was always on time, tidy, and polite. Would highly recommend.
From start to finish, the process was smooth and professional. We had a complete kitchen renovation done, and the attention to detail was brilliant. The project manager kept us updated throughout. Great team!
I recently hired Innovate Home Solutions to renovate my kitchen and bathroom, and I couldn’t be happier with the results. The entire team was professional, punctual, and paid great attention to detail. They communicated clearly throughout the project and made sure everything stayed on schedule. The quality of their workmanship really stands out — every tile, cabinet, and finish looks perfect. Highly recommend them to anyone looking for a trustworthy and skilled builder!
I recently had some renovation work done in my one-bedroom flat and couldn’t be more impressed with the professionalism and quality of the service. From the very first consultation with the Renovations Consultant through to the project’s completion, everything was handled with care, attention to detail, and excellent communication.
A special thank you to Project Manager Aldas, who kept me informed every step of the way and ensured everything was delivered exactly as promised. The whole team worked efficiently, respected my home, and left me with a beautifully finished space that exceeded my expectations.
I’m truly grateful for the hard work and dedication shown, thank you, Aldas and team, for making this such a smooth and stress-free experience!
I’m really happy with how my ground floor remodel turned out. Aldas and his team did a fantastic job turning it into a bright, open-plan space. Everything was completed on time and exactly within the quote I was given before the work started. Great communication and very professional from start to finish. Would definitely recommend!
Aldas was an absolute lifesaver for our rear kitchen extension and open-plan kitchen project! Seriously, he was incredibly helpful every step of the way, from sorting out the planning application right through to the very end. We couldn’t recommend him more highly to all our friends.
Aldas carried out bathroom adaptations / refurbishment works for me – his service was professional from beginning to end; and the quality of work was excellent.
A job well done. My experience with Refresh Renovations was exceptional from beginning to end. Aldas was a pleasure, not only did he make me feel comfortable with the outlay of the work, he was also able to offer alternatives at a higher, mid range and lower cost for my newly installed extension with my extended kitchen! I’d mentioned I spend a lot of my time in the kitchen and Aldas recommended under heated flooring. With my new porcelain tiles it works a treat. Recommendations are clearly Aldas’s strong point and any future works will be awarded to him and his team. Highly recommended.

Loft Conversion FAQs
Answers to the questions London homeowners ask most before converting a loft.
How long does a loft conversion take?
For an average loft conversion, design and approvals typically take 2–4 months and construction 10–16 weeks. The programme depends on the type of conversion, the roof structure and the approval route, and we confirm yours in writing.
Do I need planning permission for a loft conversion?
Many loft conversions can be built under permitted development, usually confirmed with a lawful development certificate. Others need planning permission, for example in flats, in conservation areas or where the roof changes significantly at the front. We confirm the right route, and our appointed architect prepares and submits any application.
Which type of loft conversion suits my house?
It depends on the roof shape, the house type and the planning position. Rear dormers suit many terraced houses, hip-to-gable conversions suit houses with a hipped roof, and mansards create the most space where planning allows. We review your roof and advise on the options.
Does a loft conversion need Building Regulations approval?
Yes. Every loft conversion needs Building Regulations approval covering structure, fire safety, insulation and the staircase. We coordinate the structural calculations and Building Control, and hand over the sign-off on completion.
Will I need a Party Wall agreement?
If your house shares a wall with a neighbour and the works affect it, for example inserting steels into the party wall, the Party Wall Act usually applies. We work with an established Party Wall surveyor and coordinate the process for you.
How much does a loft conversion cost?
Cost depends on the type of conversion, the roof structure, the number of rooms, any en-suite and the finish. We review the property first and provide a written scope and quotation, so you know what is included before work begins.
What guarantee and insurance do you provide?
Our workmanship is covered by a 24-month defects period from completion, and products we supply carry the relevant manufacturer's warranty. We hold Employers' Liability cover of £10 million, Public Liability cover of £5 million and Contract Works insurance.
