Loft Conversions in Southend

Owner-led loft conversions across Southend, from Westcliff to Shoeburyness. No deposit on the build, and you deal with Chris from survey to sign-off.

What a loft conversion costs in Southend

Rear dormer on a semi or terracefrom £45,000including drawings, structural calculations and building control
Bungalow, hip to gable with dormerfrom £55,000roof restructured and the floor built up to carry bedrooms

A Velux conversion on a loft that already has the height starts from around £28,000. All figures include VAT, and they are for a finished, signed-off conversion, not a starting price that climbs once the work begins.

I'm Chris. I run Fox Conversions from Benfleet, twenty minutes along the A127 from Southend, and we've been converting lofts round here for over 15 years, trading since 2012 and as Fox Conversions Ltd since 2014. I do the survey myself, I sort the drawings and building control, and I'm on site through the build until it's signed off. The figures on this page come from jobs we've actually done, not a price list. Along the seafront we also cover loft conversions in Leigh-on-Sea.

What decides the figure on a Southend house

Most of what we do in Southend is a rear dormer on a 1930s semi in Westcliff, Prittlewell or Eastwood, or on a Victorian terrace in Southchurch and Shoeburyness. The gap between the two figures isn't about size. It's about structure.

A semi or a terrace

The 1930s semis and the Victorian terraces already have a roof with usable volume under it. We work with the existing rafters, add steel where the calculations need it, and build the new floor into a structure broadly meant to carry weight. On a terrace, a redundant chimney often sits where the stairs want to go, and taking it out from the roofline down is part of the job, as at Trafalgar Road below.

A bungalow

The bungalows in Thorpe Bay and Shoeburyness usually need the hip taken out to a gable as well as a dormer, and the ground floor ceiling joists were never sized to carry a bedroom, so the new floor has to be built up to take the load. That's where the cost sits.

Access is the Southend extra. Tight streets, no front garden, permits for the skip. We plan it before we start, and where there's nowhere to store materials we build a loading bay into the scaffold so the garden stays clear.

What Types of Loft Conversions Work Best in Southend?

Rear dormer loft conversion by Fox Conversions

Rear dormer

The most common choice on the semis in Westcliff and Prittlewell and the terraces in Southchurch. Full head height across the back of the house, with room for a bedroom and an en-suite.

Hip to gable loft conversion by Fox Conversions

Hip-to-gable

For semis and bungalows with a sloping side roof, which is most of Thorpe Bay and Shoeburyness. The sloping side is built up into a vertical gable wall, usually combined with a rear dormer.

Velux loft conversion by Fox Conversions

Velux

Roof windows fitted into the existing slope. The lower-cost option, but only if the loft already has good height.

What affects the price

Roof type

A hipped roof usually needs more structural work than a straight gable end. Hip-to-gable adds cost, but it often adds the most usable space.

Head height

Where head height is tight, we can often lower the ceiling below to gain it. Raising the ridge usually isn't an option, because it takes the roof above its existing height, which permitted development doesn't allow. I measure this at the survey because it's the biggest single factor in how straightforward a job is.

A bathroom or en-suite

Plumbing, tiling and waterproofing add to the figure.

Finish

A plastered shell costs less than a fully fitted room with joinery and flooring.

The honest bit

These figures assume the job is done properly, the structure is right, and it's signed off. If a quote comes in a long way under them, ask what's been left out. The structural work on a bungalow especially isn't something you want done cheaply.

What's included in the price

The figures above are for the whole job, not just the build:

  1. A free survey and a fixed written quote.
  2. Architectural drawings and structural calculations.
  3. Building control, from submission to the final certificate.
  4. The full build by our own team, with Chris on site.
  5. Finishing: stairs, flooring, lighting and joinery.

You pay in stages as the work goes up. No large deposit up front.

Planning in Southend

Most loft conversions fall under permitted development, so you won't need full planning permission. You will need to apply if your house is in a conservation area, if the design goes beyond the permitted limits, or if earlier extensions have used up your permitted development allowance. Southend isn't a blanket permitted development zone: Prittlewell and Warrior Square are conservation areas, and there's an Article 4 Direction at Undercliff Gardens where some permitted development rights have been removed even though it isn't a conservation area. I check your address against the council's designations before I quote.

Southend comes under Southend-on-Sea City Council for planning, and we handle the application if one is needed.

Every conversion goes through building control, whatever the planning position. That's the part that signs off the structure and fire safety, and we manage it from submission to the final certificate.

A recent job

Trafalgar Road, Shoeburyness, SS3

An end of terrace Victorian house on Trafalgar Road. The family needed a bedroom with its own en-suite and did not want to move. Two things made it awkward: no room at the front to store materials, and a redundant chimney sitting exactly where the staircase needed to go.

What we did

  • A loading bay built into the scaffold so materials were lifted and held off the ground, keeping the garden clear for the whole job.
  • The chimney taken out from the roofline down, so the stairs went in the right place instead of being squeezed around it.
  • Rear dormer for full head height, with the steels designed by our engineer.
  • New pine staircase to match the floor, and a finish that follows the age of the house rather than fighting it.
  • Drawings, calculations and building control handled start to finish.

How it went

Before: a Victorian terrace with a loft used for storage and a chimney in the way. During: the loading bay on the scaffold, the chimney out, the steels in and the dormer framed across the back. After: a bright double bedroom and en-suite, the garden untouched, signed off by building control, and a Victorian terrace that still looks like one from the street.

Questions people ask

Velux from £28,000, rear dormer from £45,000, hip to gable from £55,000, all including VAT, drawings, structural calculations and building control. Every quote is itemised so you can see where the money goes, and your fixed price comes after the free survey.

Usually not. Most loft conversions are permitted development. The exceptions are the Prittlewell and Warrior Square conservation areas and the Article 4 Direction at Undercliff Gardens. I check your address at the survey, and we handle any application with Southend-on-Sea City Council.

Rule of thumb: if you can stand at the ridge and reach up without much room to spare, you've usually got the head height. Around 2.3 metres at the ridge is the comfortable mark. I measure it properly at the survey and tell you honestly whether it works, whether a dormer or hip to gable would gain you the space, or whether it isn't viable. I'd rather say no early than take a job that shouldn't happen.

The build itself typically takes six to eight weeks, longer where access is tight. Before that, allow time for drawings, building control and any party wall notices, which matter on a terrace. I run one job at a time, so there are no weeks where nobody turns up.

Yes, across the whole of Southend-on-Sea, including Westcliff, Leigh-on-Sea, Prittlewell, Eastwood, Southchurch, Thorpe Bay and Shoeburyness, and out to Rochford and Rayleigh.

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.

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!
