Hertfordshire Loft Conversion

More space in your Hertfordshire home, without months of your house as a building site. We design and build your new floor in our North Yorkshire factory, then crane it into place in a single day. Fixed price, 10-year guarantee, no moving out.

Why Hertfordshire homes suit our method well

Whether you’re in Harpenden, St Albans, Rickmansworth, or one of the smaller towns between, a traditional loft conversion in Hertfordshire can mean months of scaffolding through streets where planning rules are already tight. We compress the visible build into a single crane day, the rest happens as internal fit-out, out of sight, while you carry on living downstairs.

Planning across Hertfordshire, handled properly

St Albans District, covering Harpenden and St Albans itself, holds 19 conservation areas, and much of the surrounding area sits within the Metropolitan Green Belt, protection designed to preserve open land and keep neighbouring towns from merging into one another. Because your new floor is built complete to drawings before it ever reaches your home, roof finish, cladding, and detailing all agreed upfront, planning officers can review the real, finished form before any work starts on site. We handle planning and building control for you throughout.

Crane access across Hertfordshire

Whatever the site, your new floor is engineered and finished in our North Yorkshire factory, then craned into place in a single day, watertight before we leave your street. Our survey confirms access, crane swing radius, and any road closures needed as part of your fixed quote.

“Would never do a traditional loft conversion again.”

“They were really great to work with from design through to completion.”
We had an excellent experience with Moduloft. They were really great to work with from design through to completion. There are many advantages using their services. First and foremost is the speed. Without dependency on the weather means there are few interruptions to your build, which in Scotland is a massive bonus. Second is the ability to stay at your house for the duration of the build meaning you save on rental costs, and you don’t have to move out and back in, which could otherwise be a painful experience with children in tow. Another major benefit of that you are largely working with one single contractor with Moduloft. They provide all the services under one roof, and so can schedule all of the activities to occur in quick succession. All in all I can’t recommend the company enough. We are delighted with the quality of the worksmanship and our building inspector even remarked on the speed and quality.

“Loft conversion completed with only 2-3 weeks of disruption – ModuLoft make miracles happen.”
ModuLoft provided a smooth and professional service from start to finish. Andrew’s design met the brief and the installation team were efficient, effective and on schedule. Tim the MD was communicative throughout and any small issues were dealt with a no-quibble attitude. I cannot recommend this company enough.

David Nicholson · Google – 2022

“Hard to tell from the ground floor that work was being carried out upstairs.”
ModuLoft have done an amazing job with our loft conversion. We now have a master bedroom and en-suite with a balcony view from a Velux MK19. Jim & Charlie were superb – we can’t praise them enough for all their hard work. They even hoovered up at the end of each day.

Steven Payne · Google – 2016

“Expectations were smashed – install teams have to be seen to be believed.”
Team would be on site at 8AM Monday morning, having driven 5 hours from North Yorkshire to us, and worked through to 8-9 at night. Professional and flexible throughout – last minute changes accommodated. After-sales and snagging support was exemplary. Great to see a British company really excelling at what they do.
