Dormer loft conversion cost
Starts from £35,000
Naturally, the end cost of a dormer loft conversion is based on size, shape and finish, plus the current roof structure/pitch. If you choose an L-shaped version, the cost is around £15K more.
There are many aspects that make up the final cost to take into consideration. The structural work includes:
Construction of the “box”
Built-in eaves cupboards
The decorative, cosmetic finish plus fixtures and fittings include:
Freestanding accessories: storage/furniture
Dormer loft conversion options
Want to expand to the side, rear, or both?
How will you use the space?
Many homeowners extend on the back of their property. To maximise space you can go further to create an L-shaped style too.
It takes on average six to eight weeks to complete building, then add on the finishing touches.
Dormer roof conversion planning permission
Significant home improvement work is much easier when it falls under Permitted Development. This project can do so, as long as it complies with certain requirements, such as:
Height not exceeding original roof
Square footage below a certain amount (semis/detacheds’ total is larger than terraces)
Neighbours unaffected (no overshadowing/overlooking)
No balconies (except Juliet style)
Materials match character of property
Even when all of these guidelines are met, you still need a Lawful Development Certificate.
Planning permission is necessary for those living in a designated conservation area and/or a listed building.
You also need to be sure the work adheres to Building Regulations. These include:
Fire safety measures
Design of stars
Your building company will advise you on all of the legal requirements.
How Fittra can help
Our team has 10 years experience helping London homeowners achieve the dormer loft conversion of their dreams. We provide:
“Fittra completed a rear extension, loft conversion and full refurbishment of our house in Ealing late last year. This included new bathrooms, heating system (including underfloor heating), electrics and plumbing. When obtaining quotes, Fittra’s prices were in the middle of the three companies who came back to us with costs, but the fact that it was fully itemised (unlike the other costs we received) gave us piece of mind that we knew exactly what we were getting for our money. “Read More
“Can’t speak highly enough of Fittra and the job they did. They completed a rear extension, side return and loft extension and pretty much a full refurbishment of our house and garden in SW London. They not only did an incredible job, but they were also great to work with too. Vadym and Ivan’s team were incredibly efficient and hardworking and really amenable and collaborative. I have recommended them to a few friends subsequently, and will continue to do so.”
Team at Fittra possesses all the attributes necessary to be an excellent contractor: they know their market extremely well; they are diligent, responsive, and yet very understanding with their clients. They are very professional and offer cost saving alternatives when possible. The thing that has impressed me the most is the professionalism, knowledge and helpfulness of all the workers.
“We did our house fully renovation last year July 2019 – December 2019 with Fittra. We are very pleased with the results – our new kitchen (rear extension with lantern roof light), loft conversion, hardwood flooring, underfloor heating, tiling and etc.. Ivan and his team are truly professional. They finished the job with timely manner and customer satisfaction. Their breakdown quotes are easy to understand and easy to work with. We are highly recommended for Ivan, Igor and the team. Great job!!!”
