Thinking about a loft conversion in West Blatchington? Apex designs and builds them right across the BN3 area, and it’s some of our most regular work. Many local homes are suburban semis, terraces and bungalows with hipped roofs. One practical advantage of converting here is that most of the area carries relatively few heritage constraints, so a straightforward dormer or hip-to-gable can often go ahead under permitted development rather than a full planning application. Either way, we handle the whole project: design, structural drawings, any planning application, and the build itself.
What’s achievable varies from one property to the next. A three-bed semi, a bungalow and an older terrace each call for a different approach, so we never quote off a template. Ridge height, roof shape and the position of any chimney stacks all feed into it. Bungalows in particular are worth a proper look, because converting a single-storey roof can add a whole upstairs where the height allows. We start with a free, no-obligation site visit and tell you straight what your roof can deliver.
As local loft conversion builders, we take a joined-up approach from the first drawing to the finished room. Our in-house architectural support keeps design, planning and build under one roof, rather than leaving you to coordinate them, and we build to current Building Regulations throughout.

The right loft conversion for your West Blatchington home depends on the roof type, the amount of additional space you want, and whether you’re open to altering the external roofline. Five main conversion types are used across West Blatchington and the wider Hove area, and because the area’s housing is largely suburban semis and bungalows, several of them come up regularly here. We’ll recommend the right one for your property after the first visit.
A frequent choice on the semis and terraces that make up much of West Blatchington. A dormer projects outward from the existing roof slope to create standing headroom and usable floor area where the original roof sloped in. On most local homes a standard rear dormer may fall under permitted development, which is one reason it’s such a common route here. The usual limits on volume and position still apply, and a listed property would be assessed differently. The amount of space gained and the number of rooms added will vary from home to home.
Well suited to the many hipped-roof semis and bungalows across West Blatchington. Where the side of the roof currently slopes inwards rather than rising to a vertical wall, a hip-to-gable conversion rebuilds that sloping side up to a full gable, opening up the internal volume that a hipped roof otherwise loses. It’s often paired with a rear dormer to square off the new space, and on a bungalow in particular it can be the route that unlocks a genuine extra floor. Exact layouts depend on the property.
The least invasive option, and the right answer on West Blatchington properties where ridge height is already generous or where external changes to the roofline aren’t wanted. The existing roof profile stays unchanged: we strengthen the structure, insulate, board the floor and fit rooflights for daylight. Planning permission is rarely required, though listed building consent can still come into play in the rare case that the property itself is listed.
The most transformative of the five conversion types. A mansard rebuilds the rear (or sometimes front) roof slope to near-vertical to create maximum floor area and headroom. Full planning permission is almost always required. It’s less common on a standard West Blatchington semi than a hip-to-gable or dormer, but worth considering where maximum space is the priority. It’s always best to confirm the position with Brighton & Hove City Council and a planning consultant before committing.
Suited to homes with a two-storey rear projection (the “side return”), which appear among West Blatchington’s older terraces and larger semis. An L-shape conversion adds a dormer to both the main roof and the rear projection, creating an L-shaped upstairs layout. It’s a less common route here than the hip-to-gable, but it’s the sensible middle ground for properties that have the rear projection to work with and want more than a standard dormer.
Every West Blatchington home is different, and the best loft conversion is the one that works with the existing structure to deliver the most usable space. We design around your roof rather than from a standard template, checking ridge height, head heights at the walls, chimney breast positions and staircase landings before proposing a layout. That detail matters most on the area’s hipped-roof semis and bungalows, where the right design makes the difference between a tight conversion and a genuine extra floor. You’ll leave the first visit with a clearer view of what the space could deliver.
Worthing is our base, and we work regularly across Brighton & Hove, with West Blatchington an easy run along the coast and up into the north-western suburbs of Hove. We’re familiar with the general planning environment across the BN3 postcode, and dormer and hip-to-gable schemes on suburban semis and bungalows are exactly the kind of work we do most. Site visits and deliveries are straightforward to arrange, you get a local team on site, consistent standards throughout the build, and a crew that respects the home they’re working in.
Our team and specialist partners focus on a finish that stands up to close inspection: plumb walls, flush trims, clean plaster lines, and joinery finished to a high standard. On a hip-to-gable, where a new gable wall and dormer have to read as a natural part of the house, that external detailing matters as much as the rooms inside. Work is carried out to current Building Regulations, and we coordinate with your Building Control inspector at the relevant stages of the build. Examples of completed work are shown in the gallery below, and we’re happy to walk through project details and references at the first site visit.
A West Blatchington loft moves through six stages from the first visit to handover. Because most addresses here sit outside any conservation area, the consents stage is usually shorter than it is across the older parts of the city, but it is never skipped and never assumed. Drawings and any application sit with our in-house architectural support; the build is ours. Two duties remain yours in law: serving any Party Wall notice, and appointing Building Control.
The first step is a free visit to your West Blatchington home. We measure up, look at the roof structure, and check head heights and ridge clearance. On a hipped roof or a bungalow especially, we'll talk through what the space could realistically deliver. There's no cost and no obligation to proceed.
If drawings already exist we will price against them. If not, our in-house architectural support prepares the layout and the technical set needed for an application or a Lawful Development Certificate. Where the work is going ahead under permitted development the drawings are still what evidences it, so they are worth having done properly rather than sketched. The quote and an outline programme follow with them.
Many West Blatchington conversions can proceed under permitted development. Where a planning application or Lawful Development Certificate is needed, our architectural partners can help prepare and submit it to Brighton & Hove City Council on your behalf. We'd always recommend checking the planning position for your property directly with the council, and discussing any Party Wall requirements with a surveyor or architect before the build starts. Party Wall notices are the homeowner's legal responsibility and can't be served by the builder.
On-site construction begins once the consents, drawings and structural calculations are in place. Timescales vary considerably depending on the conversion type and the property, and we'll set out an indicative programme at quote stage. The opened roof is kept weatherproof throughout, and we stage deliveries carefully on West Blatchington's suburban streets and quieter closes to keep disruption to neighbours and parking to a minimum.
Building Control is yours to appoint, through the council or an approved inspector, and yours to book. We give you notice ahead of each stage so nothing is closed up before it has been seen. Permitted development changes nothing at this point: the regulations apply in full whether or not a planning application was ever needed, and that catches people out more often than it should.
With the final inspection signed off, the loft is handed back. Keep the completion certificate with your property records, and file alongside it any Lawful Development Certificate obtained for the work. Where a conversion went ahead under permitted development, that certificate is the document a buyer's solicitor will ask to see, so it is worth storing somewhere you will find it again.

The notes below are general context for West Blatchington homeowners considering a loft conversion and don’t constitute legal advice. Always confirm the position for your property with Brighton & Hove City Council, and where relevant with an architect, planning consultant or party wall surveyor, before any work starts.
Planning authority. Brighton & Hove City Council is the planning authority for West Blatchington.
Conservation area. West Blatchington’s residential streets are not covered by a conservation area. For most homes here the heritage constraints are therefore lighter than in the city’s older cores, which is one reason permitted development is so often available.
Listed buildings. The historic windmill is the area’s notable listed landmark. Listed buildings are otherwise scarce among the housing, but where a property is itself listed, listed building consent is separate from planning permission and both may be needed.
Permitted development. Across most of West Blatchington many conversions proceed under permitted development, subject to the usual limits and to any Article 4 Direction, with a Lawful Development Certificate worth obtaining for your records.
Party wall. On terraced and semi-detached homes, serving any Party Wall notice is the homeowner’s legal responsibility and can’t be done by the builder.
Apex is based in Worthing and covers West Blatchington along with the surrounding Brighton & Hove neighbourhoods, including Hangleton, Hove, Portslade and the wider city. West Blatchington is an easy run east along the coast, which keeps site visits straightforward to arrange and the build straightforward to run.
The first step is a free site visit. We measure up, assess the roof structure and head height, and talk you through realistic options. On the area’s many hipped roofs and bungalows, that includes whether a hip-to-gable is the right route. From there our trusted architectural partners can handle drawings and any planning application, and you’ll want to confirm the planning position for your property directly with Brighton & Hove City Council before the build starts.

Timescales vary considerably with the conversion type, the size and condition of the property, and the consents involved. Simpler rooflight conversions are generally the quickest, while dormer, hip-to-gable, L-shape and mansard builds take progressively longer. You’ll also need to allow time for architectural drawings, structural calculations and, where required, planning approval. In West Blatchington many conversions proceed under permitted development, which can shorten that run-up. We’ll give you a realistic programme for our part of the work at quote stage, and your architect or planning consultant will be best placed to estimate the design and consent phase.
For most West Blatchington homes, a standard dormer or hip-to-gable can often be carried out under permitted development, subject to the national rules on volume, position and listed-building status. Because the area’s residential streets aren’t covered by a conservation area, that’s the common case here. The main exception is the rare listed property, where permitted development rights are typically restricted or removed and a full planning application, made to Brighton & Hove City Council, is likely to be required. There may also be Article 4 Directions or other local restrictions on specific streets. Where a planning application or Lawful Development Certificate is needed, our trusted architectural partners can prepare and submit it on your behalf, and we’d always recommend confirming the position for your specific property directly with the council. Building Regulations apply to every loft conversion and are separate from planning.
In most cases, yes. Once the roof is opened up it’s kept weatherproof, and most of the build takes place above the existing first-floor ceiling. You should expect some noise and dust at various points, but it’s usually practical to stay in the house throughout. Steel installation and the staircase cut-through are typically the most disruptive stages, and on a hip-to-gable the gable rebuild adds a noisier spell early on. We’ll flag all of it in advance so you can plan around it, and we stage deliveries carefully on the area’s suburban streets and quieter closes.
Industry research has long suggested that a well-built loft conversion can add meaningful value to a home, though the actual uplift varies with the property, the local market and the quality of the finish. In West Blatchington, buyer demand is shaped by the schools, the open countryside on the doorstep and good links into Hove and Brighton, so an extra bedroom or bathroom is generally well received. That’s especially true for families in the area’s many three-bed semis who want to stay put rather than trade up. On a bungalow, converting the roof space can add a whole upstairs, which tends to make a noticeable difference to how the property is valued.
As a general guide, you’ll typically need a floor-to-ridge height of around 2.2 to 2.3 metres for a loft conversion to be viable, measured from the top of the existing ceiling joists to the underside of the roof ridge. Where head height is tight, a dormer or hip-to-gable can sometimes create the usable room, while a rooflight conversion generally needs the existing height to already be sufficient. Head height is one of the first things we check on the free site visit, and on the area’s bungalows in particular it’s the single biggest factor in what’s achievable. We’ll be honest with you about what’s possible before any design work begins.
The right loft conversion depends on your roof shape, the amount of space you want to gain, and whether you’re open to altering the external roofline. As a broad steer for West Blatchington, the hipped-roof semis and bungalows that dominate the area often suit a hip-to-gable, usually paired with a rear dormer to square off the space; a dormer alone suits the homes that already have a gable end; rooflight conversions work well where headroom is already generous and external changes aren’t wanted; and the older terraces with a rear projection may suit an L-shape. We’ll recommend the best option for your specific property at the free site visit.
Yes. Every conversion needs it, regardless of whether planning permission was involved. The regulations cover structural stability, normally steels and strengthened joists; fire safety, meaning escape routes, fire doors and alarms; the staircase and the headroom above it; insulation; and sound separation from the rest of the house. It is worth being clear that this sits entirely apart from the planning question, since a conversion proceeding under permitted development still has to satisfy the regulations in full. You appoint Building Control and book the inspections, through the council or an approved inspector.
