Most lofts take six to eight weeks, and you get the dates before we start. One job at a time means no weeks where nobody turns up. The site is swept down every day, and clients mention the tidiness in their reviews almost as often as the finish.

My dad Brian, a director, does the brickwork, and the same plasterer, plumber and electrician have been with us for over six years.

I arrange your drawings, structural engineer and building control, so you're not chasing anyone. And if something isn't worth doing, I'll tell you.

Most of our loft work is around Southend, Leigh-on-Sea and Rayleigh. You can see typical costs and the house types we usually work on over on our loft conversions in Southend page.

Great team, friendly, tidy and hard working Chris and the team completed a loft conversion for us recently, and did a fantastic job converting our loft. Chris is a really calm, friendly guy, who made the whole process as easy as possible. The team were really tidy as well, and the work had minimal disruption to our house throughout. I’d highly recommend them, and would use them again any day.

Chris and his team were amazing in completing my Velux loft conversion. I had a number of quotes, and I am glad I chose to give the project to Fox Conversions. From Chris’s initial visit through to completion, he and his team were professional, courteous, respectful, worked in collaboration with other tradesmen and I am very pleased with the finished result. Chris was patient when I wanted to change or add items different to the original plans such as extra windows, a media wall or a floating shelf etc. I would defiantly recommend Fox Conversions if you want a home improvement project done at a reasonable price and with a team that will not let you down. Chris delivered great service over and above what I expected. Thank you to Chris and his team.

First floor rear extension I recently worked with Chris and his team at Fox Conversions Ltd on a first-floor rear extension to create an extra bedroom and expand my kitchen. From start to finish, they were professional, efficient, and highly adaptable. Chris was always responsive, helpful, and clear in communication. Any issues were met with proactive, creative solutions that kept the project on track. The work was completed to a high standard, and I’m absolutely delighted with the result. I’d highly recommend Chris and his team. He even ensured that the neighbours were kept updated & happy throughout the process.

Loft conversion with bathroom and new boiler Chris and his team have completed work for me previously with a garage conversion, this time round I used Chris's services again but for a loft conversion because I know he is trust worthy and dependable. his work is at a good standard and his prices are competitive. He has been flexible and mostly importantly a very honest and nice person who puts his customers first. I would happily recommend his services and would use him again in the future.

We waited one year for Fox Conversions' availability to start on our loft conversion and total refurbishment of our Victorian house, and it was indeed, worth the wait! Overall project took eight months to complete, as there were changes and discovery of structural problems that needed to be addressed first. As anyone can imagine the stress for any homeowners to take on such big job, without a project manager for guidance. It was both sheer delight and relief to work with Chris as he offered clear and precise breakdown steps, costs and explanation with the work. The whole process was done professionally quick to high standards, flexibility in offering practical advice or options, no short of calamity and patience till the end. Chris and his team were punctual, friendly and tidy in their jobs. Felt like we have found 'The Foxes building empire team' for our project as various members of Chris' family were brought in to complete different parts of the project, and they were too, all amazing in their work! There was no hesitation for Chris to return to fix some minor teething issue, as this project was complete a year ago, our house at present, looks just as good and new as the initial hand over of completion! Fox Conversions come with our highest recommendations and we will not hesitate in working with them again for any future projects! As a matter of fact, our architect whom had recommended Chris to us, and he in turn, had commissioned Chris to undertake his loft conversion too! The pictures shown here isn't enough to show the quality of the workmanship and final finish of the house but hopefully it will give anybody the confidence in getting contact with them.

Outstanding Craftsmanship and a Truly Reliable Team Chris Fox and his team were an absolute pleasure to work with from start to finish. We’ve hired Chris on two separate occasions: first for smaller works, including fitting new flooring, and later for a full renovation of our entire downstairs. On both projects, the experience was consistently excellent. The quality of workmanship across the team was outstanding. Chris’s trusted plumber and electricians were equally professional, reliable, and highly skilled, which made a complex renovation feel seamless and well-coordinated.

The project was delivered on time, all our questions were answered promptly, and Chris was incredibly helpful in guiding us on materials and supplies. Even after completion, he made sure everything was finalised properly in the following weeks, which we really appreciated. We are especially impressed with the bespoke side cabinet and window seat Chris built for us. The craftsmanship is exceptional, and these pieces have become real highlights of our home. We wouldn’t hesitate to recommend Chris and his team for any project, whether it’s smaller interior work or a full renovation. It has truly been a joy working with them, and we are delighted with the final result.

Chris and his team were an absolute pleasure to work with, he's knowledgeable and skilled and his quote was very reasonable. We were trepidatious about taking on such a large renovation project, comprising a loft conversion and full refit, with no prior experience, but Chris's arrival on site assuaged our concerns, and the project went smoothly with only minor hiccups. Overall I cannot recommend Fox conversions enough.

Dormer loft conversion Fox Conversions were a pleasure to work with. They built our Dormer loft conversion with en-suite, and the result looks fantastic. The build was quick, passed all inspections, and met every requirement. Pricing was very reasonable, including building control drawings. Chris Fox is approachable, skilled, and improved the design during the build. He promptly fixed any snags, and his team was courteous. Highly recommend Fox Conversions for any extension project!

Questions People Ask Before They Call

Not on the build. Drawings are paid for separately, then you pay in fixed stages as the work goes up.

Usually not for a loft or garage conversion. Most fall under permitted development and need building regulations approval only. Conservation areas are the main exception. I check your address before I quote.

Six to eight weeks for most lofts, two to four for a garage. I run one job at a time, so there are no gaps.

No. I work from the outside in, and the loft is sealed off from the house until the staircase goes in near the end.

Velux from £28,000, dormer from £45,000, hip to gable from £55,000, all including VAT, steels and building control. See the full guide on the loft conversions in Essex page or try the cost calculator.
