What is a Loft Conversion?

A loft conversion essentially transforms your empty attic space into a usable room in your home. The term refers to converting the roof space into a bedroom, office, playroom, or storage area as well as extending the existing floorspace with a dormer extension.

Loft conversions add extra room and floor space without the high costs and disruption of a full home extension. The unfinished attic space is reframed and walled to create a livable floor space. Stairs leading up to the new loft room are typically added.

Depending on your home’s structure, the roof may need to be reinforced and raised to achieve sufficient height. Dormer windows can be installed to allow light into the new loft space. Insulation, flooring, electrics, and finishing will also be required to properly convert the space for habitation.

Adding a loft conversion to a standard two-story home can increase resale value by 10-25%. Extra living space and bedrooms are highly desirable for buyers. Loft conversions provide an effective way to expand your Brighton home and get a significant return on investment.

Cost Factors for Brighton Loft Conversions

Several variables affect the total price you can expect to pay when converting your Brighton loft:

  • Size of the loft space – Larger lofts that span the full footprint of the house cost more than smaller lofts. You pay for materials and construction based on total square footage.
  • Roof work required – Some roofs need extensive reinforcement and alterations to raise height, including adjustments to rafters, braces, and supports. Pitched roofs are simpler than hipped or valleys.
  • Dormers – Adding dormers (extensions) provides light but costs more than simply using Velux windows or skylights. The number and size of dormers impact price.
  • Access – New stairs need to be built if there is no existing access. Stairs can take up valuable floor space. Good access makes conversion easier.
  • Level of finish – High-end fixtures, flooring, and custom elements raise the price tag. Basic conversions remain quite affordable.
  • Construction challenges – Converting more complex roof structures or achieving required ceiling heights can drive up costs due to additional work needed.
  • Additional features – Skylights, built-in storage, en-suite bathrooms, and electrical extensions all add to the overall conversion cost.

Planning Permission for Loft Conversions

Most loft conversions in Brighton don’t require planning permission if they meet certain conditions:

  • Conversion stays within the existing roof space with no major extensions built.
  • Side-facing dormers are not wider than pre-existing windows.
  • Dormers are set back at least 0.3m from the eaves.
  • No more than 50 cubic meters of additional internal roof space was created.
  • Materials match the existing house.
  • The conversion does not overlook any neighboring properties.

Even if the above criteria are met, you still need to confirm with your local Brighton planning office. If your loft conversion does exceed the limits, full planning permission will be required, adding time and costs. An experienced contractor can advise you on meeting regulations.

Factors That Impact Loft Conversion Costs in Brighton

Here is a more in-depth look at the key factors that will determine the total cost of your Brighton loft conversion project:


The amount of usable space you wish to create in your loft determines costs. Typical loft conversions range from 150 to 300 square feet. Materials, construction time, and labor costs directly correlate to the loft’s total footprint.

Structural Work Needed

Some lofts require significant structural reinforcement before being converted, especially if walls need to be removed downstairs. This includes:

  • Sistering new joists next to existing ones
  • Adding load-bearing beams
  • Strengthening rafters and tie beams
  • Reinforcing roof timbers
  • Installing steel stanchions and columns

Roof Alterations

Does your existing roof shape and structure allow the height needed for conversion without significant alterations?

Raising the ridge line for a pitched roof, reconfiguring roof joists, and adding substantial dormers or skylights will boost project costs. Removing chimney breasts and stray walls can also add expense.

However, if your roof only needs basic reinforcement using existing headroom, costs remain reasonable.

New Staircase

If your current stairs don’t extend into the loft space, a new staircase will be required for access. This often requires allocating living area floor space to the new stairs.

Dormers vs. Velux Windows

Adding one or more dormer extensions provides light and expanded floorspace, but costs more due to the roofing, windows, and finishing work.

Velux windows or skylights are a budget-friendly alternative to dormers. However, they allow less light which may limit the loft’s use.

Insulation Costs

Proper insulation in walls, floors, and the roof cavity is essential in converted lofts to prevent heat loss and moisture issues.

Electrical and Plumbing

New wiring, lighting circuits, switches, sockets, alarm systems, and TV points all need to be installed to code by a certified electrician. Plumbing may be required for en-suites.

Plastering and Decorating

New walls and ceiling areas must be plasterboarded, taped, plastered, and painted. Cornice and trim molding finish off the space nicely.

Contingency Buffer

It’s recommended you add a 10-15% contingency fund to your total budget for unexpected issues or changes that arise during the loft conversion process.

By understanding these main elements that comprise a full loft conversion, you can budget for your project appropriately.

How Long Does a Loft Conversion Take in Brighton?

You can expect a typical loft conversion project in Brighton to last 4-6 months from start to finish.

However, the timeline depends on factors like the conversion complexity, your agreed schedule with the builder, availability of materials, and weather delays.

Here is the typical project timeline:

  • Weeks 1-2: Initial surveys, planning, and council approvals. Scaffolding erected.
  • Weeks 3-4: Main structural work. The roof is reinforced and builders start framing.
  • Weeks 5-7: Roof windows/dormers installed. Internal walls, and stairs were erected.
  • Weeks 8-12: Roofing, insulation, and plumbing work done. Plastering completed.
  • Weeks 13-16: Electrics, flooring, decorating, and finishing work. Remove scaffolding.
  • Weeks 17-24: Potential delays from weather, materials shortages, or additional structural work found.
  • Weeks 25-28: Snagging, final quality control checks, and sign-off.

Proper project planning is crucial to avoid delays and ensure the builders finish on schedule. Discuss timing thoroughly with your builder before starting.

Finding the Right Loft Conversion Builder in Brighton

Choosing the right builder is the most important decision for your loft conversion project. Here’s how to find an experienced, reliable contractor in Brighton:

  • Seek referrals – Ask neighbors, friends, local forums for builder recommendations. Referrals provide confidence.
  • Check qualifications – Confirm builders are Certified Loft Conversion Specialists and FMB approved. Request proof of accreditation.
  • Look for experience – Find a builder with extensive loft conversion expertise. Ask to see past project examples and scope.
  • Interview multiple builders – Meet with 3-5 builders in person. Get quotes and compare approach, pricing, timelines.
  • Check reviews – Look for consistently positive customer reviews on Google, Facebook and sites like TrustATrader. Beware major inconsistencies.
  • Confirm availability – Reputable builders book up. Find one able to start your project on your preferred schedule.
  • Get everything in writing – Have a thorough contract detailing scope, materials, timeline, responsibilities, and payment schedule.

Take time to carefully screen builders to find the right fit for your project goals, budget, and timeline. Rushing the decision can lead to problems down the road.

Designing Your Loft Conversion in Brighton

The design possibilities for your loft conversion are wide open. Here are some of the most popular uses and layout options:

Extra Bedroom

Adding a bedroom or two is the most common loft conversion use, ideal for children or guests. Optimize the layout for sleeping space, wardrobes, and optional en-suite bathroom.

Home Office

Lofts make quiet, private home office spaces. Include desk, shelving, cabinets, power points. Add a divider wall for work/life balance. Skylights aid daytime focus.

Play Room

Let kids enjoy their own space with a playroom filled with toys, games, arts supplies. Add colorful paint, whimsical decor, safety railings. Hide mess out of sight.

Storage Space

A basic unfinished loft can serve as attic storage space. Use for off-season clothes, holiday decorations, memorabilia. Add flooring, lighting and access stairs.

Multi-Purpose Room

Maximize flexibility with an open plan loft for reading, yoga, creative projects, fitness, or whatever needs arise. Arrange portable dividers or curtains to delineate zones.

Luxury Suite

Treat yourself to a private luxury bathroom, sitting area, TV space for relaxing. Include high-end finishes like freestanding tubs, luxury vinyl plank floors, custom built-ins.

Consider how you want to enjoy the additional space in your home. An experienced architect can help design a loft tailored to your family’s needs and lifestyle.

Alternatives to Loft Conversions in Brighton

If converting your existing loft isn’t feasible or cost-effective, consider these alternative options for adding much-needed space to your Brighton home:

Rear or Side Extension

A ground floor extension pushes out the external walls to expand your home’s footprint. Provides instant additional room without impacting current layout. Requires planning permission.

Dormer Bungalow Conversion

Converts your bungalow attic into living space by adding head height within a dormer. Less hassle than a full loft conversion and extends usable space.

Garage Conversion

Turn your garage into an office, gym, studio or extra bedroom. Instant useable square footage if garage is attached and already has electrics.

Basement Conversion

Digging down into a basement can add significant floorspace for a game room, home cinema, or apartment. Costly but minimally disruptive.

Container Home Office

Use an insulated shipping container as a detached home office or gym in the garden. Fast and relatively affordable extra space.

Depending on your property constraints, one of these options may better provide the extra room you need. Discuss best routes for your home with an architect or builder.

Design Tips for Loft Conversions

Here are some key design tips for maximizing usable space, light, and ergonomics in your Brighton loft conversion:

  • Take advantage of the full roof space, including knee walls and eaves. Built-in storage solves clutter issues.
  • Angle the bed or desk under sloped eaves for extra space efficiency.
  • Incorporate sun pipes, tubular skylights or large velux windows for natural light. Optimize southern exposure.
  • Use glass balustrades on open stairs and galleries overlooking the loft to maintain light.
  • Add discreet access doors leading to eaves storage areas. Use the awkward small spaces.
  • Include plenty of power outlets, USB charging points, ethernet, cable, and phone connections for true livability.
  • Use space-saving walk-in showers and compact toilets to allow room for freestanding baths.
  • Choose furnishings that don’t obstruct light like platform beds vs. bulky headboards.
  • Paint the ceiling, floors and trims bright white to give the illusion of extra height and space.

With careful planning, even the most awkward angled loft can become the most stylish and usable space in your Brighton home.

Building Regulations for Loft Conversions

All loft conversion work must comply with UK building regulations designed to ensure safety and structural integrity. Here are some key regulations to be aware of:

  • Fire safety measures like fire-resistant doors, walls and flooring may be mandatory, especially adjoining the stairs.
  • Stairs should be a minimum of 850mm wide and follow strict dimensional riser/tread requirements.
  • Staircases, balustrades and guard rails must meet minimum headroom and ballister spacing standards.
  • Any electrical work must meet local codes. Provide the required smoke and carbon monoxide detectors.
  • Structural calculations prove the load bearing capacity of the existing and new framework.
  • Insulation R-values for walls, roof and dormers meet thermal efficiency requirements.
  • Ensure adequate drainage, ventilation and soundproofing. Avoid leaks.
  • Required head height clearances account for flooring depth and sloped ceilings.
  • Building inspector approves each stage before continuing. You may need architectural plans.

Reputable builders handle ensuring regulatory compliance as part of the service. Get all paperwork and council approvals handled properly.
