Thinking about a loft conversion in Findon? Apex designs and builds them across the village and the wider BN14 area, just up the A24 from our Worthing base. Findon sits in a fold of the South Downs, and that setting shapes the whole project: the village lies within the South Downs National Park, so applications here go to the National Park Authority rather than the district council, and the design of anything visible from the street or the surrounding downland tends to be looked at closely. We handle the work from design and structural drawings through any planning application to the finished build, so you are not left coordinating separate trades yourself.
What is achievable varies a great deal from one Findon property to the next. A flint-and-brick cottage in the historic core, a later village home and a larger detached house on the edge of the countryside 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 a conservation area or is itself listed all feed into the recommendation.
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, and we build to current Building Regulations throughout. We start with a free, no-obligation site visit and tell you straight what your roof can deliver. Contact us for a free quote on your Findon loft conversion.
The right loft conversion for your Findon home depends on the roof type, the amount of additional space you want, and whether you are open to altering the external roofline. Five main conversion types are used across Findon and the wider Worthing area. Because the village setting inside the National Park means external changes are scrutinised more closely, the right answer here genuinely varies by property, and we will recommend one after the first visit.
A common way to add real headroom on Findon’s later village homes and semis. A dormer projects outward from the existing roof slope to create standing headroom and usable floor area where the original roof sloped in. Inside a National Park, and particularly close to a conservation area, a dormer is more likely to need a full planning application than to fall under permitted development, and its size, position and materials will be assessed against the local setting. The space gained varies from home to home.
Well suited to the hipped-roof semis and detached homes found among Findon’s later streets. 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 and opens up internal volume. It is often paired with a rear dormer where the original roof profile is restrictive. In this setting the external change is likely to be reviewed by the National Park Authority, so the detailing matters. Exact layouts depend on the property.
Often the most sympathetic option in a downland village, and frequently the right answer on Findon homes in or near a conservation area where keeping the roof profile unchanged matters most. 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 for a rooflight conversion, though listed building consent can still apply where 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 inside the National Park the design tends to be looked at more closely still. It is worth confirming the position with the South Downs National Park Authority and a planning consultant before committing.
Suited to older homes with a two-storey rear outrigger, the “side return”, which appear among Findon’s period cottages and earlier houses. An L-shape conversion adds a dormer to both the main roof and the rear outrigger, creating an L-shaped upstairs layout. It is often the sensible middle ground for a period property that wants more than a standard dormer without the planning complexity of a full mansard.
Every Findon 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 village properties, where the National Park setting means the external design has to earn its consent. You will leave the first visit with a clearer view of what the space could deliver.
Worthing is our base, and Findon is a short run up the A24, well inside our regular working area. We are familiar with the general planning environment across the BN14 postcode, including the closer attention that applications inside the National Park and near the village conservation areas attract, 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 are 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 is the level of detail the older homes in a protected village setting, 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 are happy to walk through project details and references at the first site visit.
A typical Findon loft conversion runs through six stages. We are 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 relevant authority.
The first step is a free visit to your Findon home. We measure up, look at the roof structure, and check head heights and ridge clearance. We will also talk through what the space could realistically deliver, including how the National Park setting and any nearby conservation area affect the options. There is no cost and no obligation to proceed.
If you already have drawings we will 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.
Because Findon lies inside the South Downs National Park, a planning application or Lawful Development Certificate here is submitted to the South Downs National Park Authority rather than the district council, and our architectural partners can help prepare and submit it on your behalf. That is more likely to be needed for homes in or near the conservation areas, and for listed properties. We would always recommend checking the planning position for your property directly with the National Park Authority, 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 cannot 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 will set out an indicative programme at quote stage. The opened roof is kept weatherproof throughout, and we stage deliveries carefully on Findon's narrower village lanes 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 have 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 will want to keep the completion certificate and related documentation with your property records for any future sale.

The notes below are general context for Findon homeowners considering a loft conversion and don’t constitute legal advice. Always confirm the position for your property with the South Downs National Park Authority, and where relevant with an architect, planning consultant or party wall surveyor, before any work starts.
Planning authority. Findon village lies wholly within the South Downs National Park, so planning applications go to the South Downs National Park Authority, with Arun District Council providing other district services.
National Park. Being inside the Park means external changes to a roof are generally assessed more closely for their effect on the landscape and the village, so early design advice is worthwhile.
Conservation areas. Findon has designated conservation areas covering the historic village core and the Nepcote area, where permitted development rights are typically restricted and external detailing is scrutinised.
Listed buildings. The village has a number of listed buildings, so where a property is listed, listed building consent is separate from planning permission and both may be needed.
Permitted development. Some conversions still proceed under permitted development, but National Park status and any Article 4 Direction can restrict it, so a Lawful Development Certificate is worth obtaining.
Party wall. On terraced and semi-detached homes, serving any Party Wall notice is the homeowner’s legal responsibility and cannot be done by the builder.
Apex is based in Worthing and covers Findon and the surrounding villages and neighbourhoods, including Findon Valley, High Salvington, Durrington and Storrington. Findon is a short run up the A24 from our base, 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 National Park setting and the village conservation areas affect what is achievable. From there our trusted architectural partners can handle drawings and any planning application, and you will want to confirm the planning position for your property directly with the South Downs National Park Authority before the build starts.

Common questions from Findon 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 will also need to allow time for architectural drawings, structural calculations and, where required, planning approval. In Findon that approval goes to the South Downs National Park Authority, and it tends to take longer for homes in or near the conservation areas, or for listed properties. We will 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.
Quite possibly, and more often than in a town outside the National Park. Because Findon village lies wholly within the South Downs National Park, applications go to the South Downs National Park Authority rather than to Arun District Council, and permitted development rights are more likely to be restricted, especially inside the village conservation areas or where a property is listed. Some conversions still proceed under permitted development, subject to the national rules on volume, position and listed-building status, but it is always worth confirming. Where a planning application or Lawful Development Certificate is needed, our trusted architectural partners can prepare and submit it on your behalf, and we would always recommend confirming the position for your specific property directly with the National Park Authority. Building Regulations apply to every loft conversion and are separate from planning.
In most cases, yes. Once the roof is opened up it is 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 is usually practical to stay in the house throughout. Steel installation and the staircase cut-through are typically the most disruptive stages, and we will flag both in advance so you can plan around them. That matters in Findon, where the narrower village lanes 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 Findon, buyer demand is shaped by the village character, the setting inside the National Park and the easy links down the A24 into Worthing, so additional bedroom or bathroom space is generally well received. That is especially true for families who want to stay in the village rather than trade up into a larger property elsewhere. For many homeowners, adding a room upstairs also removes the immediate pressure to move within a tight local market.
As a general guide, you will 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 will be honest with you about what is 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 are open to altering the external roofline. As a broad steer, in a protected village setting like Findon a rooflight conversion is often the most sympathetic where keeping the roof profile unchanged matters; the older cottages with a rear outrigger can suit an L-shape; the hipped-roof semis and detached homes among the later streets may benefit from a hip-to-gable, sometimes paired with a rear dormer; and a mansard can suit a property looking for maximum floor area, subject to National Park and conservation consent. We will 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 have appointed so the right stages are inspected at the right times.
