Thinking about a loft conversion in West Tarring? Apex designs and builds them right across the BN13 area, and it’s a core part of the work we carry out around Worthing. The planning picture here changes street by street: homes in the protected historic core are looked at more closely on external detailing, while the later residential streets that grew up around it can often pursue a dormer or hip-to-gable under permitted development. We handle the whole project either way, from design and structural drawings through any planning application to the build itself.
What’s achievable varies from one property to the next. A period home near the old village, a hipped-roof semi and a bungalow each call for a different approach, so we never quote off a template. Ridge height, roof shape, the position of any chimney stacks, and whether the property sits inside the conservation area or is itself listed all feed into the recommendation. 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 Tarring 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 Tarring and the wider Worthing area. Because the housing ranges from period homes near the old village to later suburban streets, the right answer genuinely varies by property. We’ll recommend the right one after the first visit.
A frequent choice on the semis and terraces across West Tarring’s later residential streets. A dormer projects outward from the existing roof slope to create standing headroom and usable floor area where the original roof sloped in. On many properties a standard rear dormer may fall under permitted development, though closer to the conservation area around the historic core a full planning application is more likely to be needed and its size and position assessed more closely. The amount of space gained and the number of rooms added will vary from home to home.
Well suited to the hipped-roof semis and end-of-terrace homes common across the wider West Tarring area. 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 additional internal volume. It’s often paired with a rear dormer where the original roof profile is restrictive. Exact layouts depend on the property and its setting.
The least invasive option, and often the right answer on West Tarring properties where ridge height is already generous or where external changes to the roofline aren’t wanted. It’s particularly suitable for homes in and around the conservation area, where keeping the roof profile unchanged matters. The existing roof stays as it is: 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 if 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, and on conservation-area frontages around the historic core the design detailing tends to be looked at more closely. Worth confirming the position with Worthing Borough Council and a planning consultant before committing.
Suited to older terraces and semis with a two-storey rear outrigger (the “side return”), which appear among West Tarring’s earlier streets. An L-shape conversion adds a dormer to both the main roof and the rear outrigger, creating an L-shaped upstairs layout. It’s often the sensible middle ground for period homes that want more than a standard dormer without the planning complexity of a full mansard.
Every West Tarring 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 all the more on the older homes around the historic core. You’ll leave the first visit with a clearer view of what the space could deliver.
Worthing is our base, and West Tarring sits right on our doorstep. We’re familiar with the general planning environment across the BN13 postcode, including the closer attention the conservation area around the old village attracts, and site visits and deliveries are straightforward. 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. That’s the level of detail the older homes around the historic core, in particular, tend to demand. 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 typical West Tarring loft conversion runs through six stages. We’re involved from initial design through to the finished build via our trusted architectural partners, while some legal responsibilities (Party Wall notices, listed building consent, Building Control submission) remain the homeowner’s and should be discussed directly with a surveyor, architect or the council.
The first step is a free visit to your West Tarring home. We measure up, look at the roof structure, and check head heights and ridge clearance. We'll also talk through what the space could realistically deliver, including whether the property's position relative to the conservation area affects the options. There's no cost and no obligation to proceed.
If you already have drawings we'll work from those. If not, our trusted architectural partners can handle the design phase, including layout planning and technical drawings, so you get a joined-up approach from the start. Alongside the drawings we produce a detailed quote and a proposed build programme.
Where a planning application or Lawful Development Certificate is needed, our architectural partners can help prepare and submit it to Worthing Borough Council on your behalf. That's more likely for homes in or near the conservation area, and for listed properties. 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 Tarring's busier residential roads and the narrower lanes around the old village core to keep disruption to neighbours and parking to a minimum.
Building Control inspections are booked in by you (through your local authority or an approved inspector you appoint) at the relevant stages of the build. We build to the current Building Regulations throughout and coordinate with whoever you've appointed so the right stages are inspected at the right times.
Once the final inspection has been signed off on your side, we hand the finished loft over. You'll want to keep the completion certificate and related documentation with your property records for any future sale.

The notes below are general context for West Tarring homeowners considering a loft conversion and don’t constitute legal advice. Always confirm the position for your property with Worthing Borough Council, and where relevant with an architect, planning consultant or party wall surveyor, before any work starts.
Planning authority. Worthing Borough Council, through the Adur & Worthing shared planning service, is the planning authority for West Tarring.
Conservation area. West Tarring’s historic core sits within a designated conservation area where permitted development rights are typically restricted and external details such as dormer position and roof materials are assessed more closely.
Listed buildings. The old village has an unusually rich concentration for the Worthing area, including the former archbishop’s palace, the medieval parish church and a rare surviving terrace of late-medieval timber-framed cottages, so where a property is listed, listed building consent is separate from planning permission and both may be needed.
Permitted development. Across the later residential streets away from the historic core, 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 Tarring and the surrounding neighbourhoods, including Broadwater, Durrington, Goring-by-Sea and the central seafront. West Tarring sits right on our doorstep, which keeps site visits easy 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, including how the conservation area affects properties in or near the historic core. 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 Worthing Borough Council before the build starts.

Common questions from West Tarring homeowners considering a loft conversion. If yours isn’t covered, get in touch through the contact form and we’ll be in touch with an answer.
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. That approval tends to take longer for homes in the conservation area around the historic core, or for listed properties. 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.
It depends on where in West Tarring you live and on the details of the property. Homes inside the conservation area around the old village, or that are themselves listed, typically have permitted development rights restricted or removed, with a full planning application to Worthing Borough Council likely to be required. There may also be Article 4 Directions or other local restrictions. Across the later residential streets away from the historic core, many loft conversions can proceed under permitted development, subject to the national rules on volume, position and listed-building status. 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 we’ll flag both in advance so you can plan around them. That matters in West Tarring, where the busier residential roads and the narrower lanes around the old village core mean deliveries and parking need careful planning.
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 Tarring, buyer demand is shaped by the historic village character, the schools and good links into Worthing town centre, so additional bedroom or bathroom space is generally well received. That’s especially true for families who want to stay put rather than trade up into a larger property nearby. For many homeowners, adding a room upstairs also removes the immediate pressure to move within a tight local market.
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 mansard can sometimes create the usable room, while a rooflight conversion generally requires the existing height to already be sufficient. Head height is one of the first things we check during the free site visit, and we’ll be honest with you about what’s achievable 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, the older homes around the historic core often suit a dormer or, where there’s a rear outrigger, an L-shape, with rooflight conversions favoured where keeping the roof profile unchanged matters; the hipped-roof semis across the later residential streets can benefit from a hip-to-gable, sometimes paired with a rear dormer; and mansards can suit period terraces looking for maximum floor area, subject to planning and conservation consent. We’ll recommend the best option for your specific property at the free site visit.
Yes. Every loft conversion in the UK needs to meet the Building Regulations, regardless of whether planning permission is required. The regulations cover structural stability (often requiring steel beams and reinforced floor joists), fire safety (escape routes, fire doors, smoke alarms), staircase design and headroom, thermal insulation, and sound insulation between the new rooms and the rest of the house. Building Control submission and inspections are the homeowner’s responsibility, either through the local authority or through an approved inspector you appoint. We build to the relevant standards throughout and coordinate with whoever you’ve appointed so the right stages are inspected at the right times.
