Planning a loft conversion in Hollingdean? Apex builds them across the BN1 area, and Hollingdean is exactly the kind of neighbourhood where a well-designed loft earns its keep. The area sits in its own valley on Brighton’s inner north-east side, between Preston Park and Moulsecoomb, with brick terraces on the lower slopes rising to later estate homes and low-rise flats further up. Footprints here are mostly modest and gardens are precious, so when a household needs another bedroom or a workspace, the roof is usually the most practical place to find it.
The build itself has to respect how these streets work. On a terraced home you share structure with neighbours on both sides, which makes the Party Wall step a genuine part of the project rather than a formality, and the valley’s sloping streets and on-street parking mean scaffolding and deliveries need proper planning. The upside is a simpler consent picture than much of Brighton: Hollingdean’s residential streets sit outside the city’s conservation areas, so many conversions here can proceed under permitted development. Roof shapes vary from plain pitched terraces to hipped estate semis, and each points to a different conversion, so we always start from the individual property.
As local loft conversion builders, we run design, planning and build as one joined-up job. Our in-house architectural support covers layout planning and technical drawings, we build to current Building Regulations throughout, and it all starts with a free, no-obligation site visit where we tell you plainly what your roof can and cannot do.

Hollingdean’s mix of terraces, estate semis and flats means no single conversion type dominates, and the right choice depends on your roof shape, how much space you need and whether the roofline can change. These are the five types we build across the neighbourhood and the rest of north-east Brighton, and after the first visit we will tell you which one your home actually suits.
The workhorse conversion for Hollingdean’s terraced streets. Building a dormer out from the rear roof slope turns a cramped, sloping attic into a room with standing headroom and straight walls, usually taking a bedroom and often a shower room with it. On many terraces a rear dormer falls within permitted development, and because these homes share party walls on both sides, we design the steelwork and load paths with the neighbouring structures in mind from the outset.
The answer for the hipped roofs found on Hollingdean’s estate semis and end-of-terrace homes. The sloping side of the roof is rebuilt as a full-height gable wall, recovering the internal volume the hip takes away, and a rear dormer is usually added to square the space off. It is a bigger intervention than a dormer alone, but on the right roof it is the difference between a compromise and a proper double bedroom.
The lightest-touch option: the roofline stays exactly as it is while the floor is strengthened, the space insulated and boarded, and rooflights fitted. On Hollingdean’s plainer pitched roofs it works where the ridge is already tall enough, which we measure carefully at the first visit, and it suits homes where keeping cost and disruption down matters more than maximising floor area. Rooflights alone rarely need planning permission.
The largest of the five conversion types, rebuilding a roof slope to near-vertical to gain the maximum possible headroom and floor area. A mansard nearly always needs full planning permission, and in Hollingdean it is worth weighing against a dormer or hip-to-gable, which often deliver the space a household actually needs with less cost and complexity. Where a mansard is the right call, we would confirm the planning position with Brighton & Hove City Council before design work begins.
An option for the area’s older terraced homes with a two-storey rear outrigger. Dormers over the main roof and the rear wing connect into an L-shaped layout, which can gain two rooms in a single project, often a bedroom plus a bathroom or study. It involves more structural work than a single dormer, and we will tell you honestly at the site visit whether your roof layout makes it worthwhile.
On Hollingdean’s compact homes, every centimetre of the new room has to count. We start by measuring what the roof actually offers: ridge height, the usable width between party walls, chimney positions and where a staircase can land without eating into the floor below. Then we design the conversion around those facts, choosing the dormer size, layout and storage that squeeze the most usable space from the volume available. The aim is a room that feels like it was always part of the house, not an afterthought under the roof.
Apex is a Worthing firm, and Brighton is part of our weekly round: Hollingdean sits well inside the area we cover day to day. We know how the BN1 planning picture applies on this side of the city, we plan builds around sloping streets and on-street parking as a matter of course, and we keep neighbours in mind on terraces where the work happens close to the party wall. One team handles your job from survey to handover, and we turn up when we say we will.
A loft conversion is judged by how it feels to live in, and that comes down to the finish: clean plaster, square corners, doors that close properly and stairs that feel solid underfoot. Our team and specialist partners deliver that standard on every Hollingdean job, large or small, building to current Building Regulations throughout and coordinating with your Building Control inspector at each required stage. Recent completed projects are in the gallery below, and we are glad to share references at the first visit.
A Hollingdean loft conversion follows six stages from first visit to handover, with Apex and our trusted architectural partners alongside you throughout. A few legal responsibilities (Party Wall notices, Building Control submission, any listed building consent) stay with the homeowner and should be discussed with a surveyor, architect or the council directly.
We visit your Hollingdean home free of charge, measure the loft, check ridge height and head clearance, and look at the roof structure and party walls. You get a straight answer on what the space can realistically become and which conversion types fit your roof, plus early warning of anything that needs planning ahead, from parking for the skip to the Party Wall conversation with your neighbours.
Working drawings come either from your own architect or from our trusted architectural partners, who can take the design from first layout sketches through to technical drawings ready for structural calculations. With the design settled you receive an itemised quote and an indicative programme, so you know what is included before anything is committed.
Many Hollingdean conversions proceed under permitted development, and where a planning application or Lawful Development Certificate is needed our architectural partners can prepare and submit it to Brighton & Hove City Council on your behalf. Confirm the position for your own property with the council, and on a terraced or semi-detached home talk to a party wall surveyor early: serving Party Wall notices is the homeowner's legal responsibility and cannot be done by the builder.
The build starts once drawings, calculations and any consents are in place. We keep the opened roof weatherproof at every stage, sequence deliveries around the valley's sloping streets and on-street parking, and keep the site tidy on terraces where neighbours live a wall away. Duration depends on the conversion type and the property; the programme from quote stage keeps expectations realistic.
Building Control sign-off runs through the inspector you appoint, via the local authority or an approved private inspector. We build to current Building Regulations at every stage and coordinate directly with your inspector so structural work, fire safety measures and insulation are checked at the right points in the programme.
When the final inspection has been passed on your side, the loft is yours. File the completion certificate and paperwork somewhere safe with your property documents; you will need them when the house is next sold or remortgaged.

The notes below are general context for Hollingdean 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 Hollingdean, as for the rest of the city.
Conservation areas. Hollingdean’s residential streets sit outside the city’s designated conservation areas, so external roof alterations face fewer heritage restrictions here than in much of central Brighton.
Permitted development. That means many Hollingdean conversions can proceed under permitted development, subject to the national limits on volume and position, with a Lawful Development Certificate worth obtaining for your records.
Shared houses. Changing a family home into a small shared house (HMO) needs planning permission across Brighton & Hove under an Article 4 Direction, and Hollingdean was among the first parts of the city covered, so landlords adding loft rooms should check the position early.
Flats. Parts of the neighbourhood are low-rise flats, where roof-space ownership and freeholder consent must be confirmed before any loft work is considered.
Party wall. Hollingdean’s terraces share structure on both sides, and serving the Party Wall notices this requires is the homeowner’s legal responsibility, not the builder’s.
Apex is based in Worthing and works right across Brighton and Hove, so Hollingdean jobs slot into a patch we are in every week, alongside Preston Park, Withdean, Patcham and the rest of the city. That regular presence keeps surveys, deliveries and the day-to-day running of your build straightforward from start to finish.
Everything begins with a free site visit. We measure the roof, check the structure and head heights, and give you an honest picture of the options, including how party walls, parking and access on your street shape the build. Our trusted architectural partners can then handle drawings and any application that is needed, and you should confirm the planning position for your property directly with Brighton & Hove City Council before work starts.

The questions we hear most from Hollingdean homeowners weighing up a loft conversion. Anything else on your mind, drop it through the contact form and we will get back to you.
The build time depends mainly on the conversion type and the condition of the roof. A rooflight conversion is the quickest, a rear dormer on a terrace sits in the middle, and hip-to-gable and L-shape builds take longer again. On top of the on-site work, budget time for drawings, structural calculations and, where one is needed, a planning decision. We set out a realistic programme for the construction phase with your quote, and your architect or planning consultant can advise on the design and consent timeline.
Frequently not. Hollingdean’s streets sit outside Brighton’s conservation areas, so a loft conversion on a house here can often proceed under permitted development, within the national limits on volume, height and position. The main local exception is change of use: turning a family home into a small shared house (HMO) requires planning permission across the city under an Article 4 Direction, which matters if the loft room is part of a rental plan. A Lawful Development Certificate is worth obtaining even where no application is needed. Our trusted architectural partners can prepare and submit whatever paperwork applies, and we always advise confirming the position for your property directly with Brighton & Hove City Council. Building Regulations apply to every conversion either way.
Yes, in nearly every case. Most of the work happens above your existing ceiling, the roof is kept weatherproof once opened, and the messiest stages, typically the steel lift and the staircase cut-through, are flagged well in advance so you can plan around them. On Hollingdean’s terraced streets we also coordinate deliveries and skip placement around on-street parking, which keeps the disruption manageable for you and for the neighbours either side.
It depends on the property and the market, but industry research has long indicated that a good loft conversion adds worthwhile value. Hollingdean is one of north Brighton’s more accessible family neighbourhoods, and an extra double bedroom moves a house into a different bracket for the families and sharers who look here. For plenty of owners the bigger win is avoiding a move altogether: gaining a room in the roof costs less upheaval than trading up in a city where every extra bedroom is fought over.
The usual benchmark is around 2.2 to 2.3 metres measured from the top of the ceiling joists to the underside of the ridge. Some of Hollingdean’s plainer pitched roofs are on the tighter side, which is exactly the situation a rear dormer is designed to solve, creating full standing headroom across the new room. Checking the true measurements is the first job at our free site visit, and if the numbers do not work we will say so before you spend anything on design.
For most of Hollingdean’s terraces, a rear dormer is the natural starting point, with an L-shape worth considering where there is a rear outrigger to build over. The hipped roofs on estate semis and end-of-terrace homes usually call for a hip-to-gable, often combined with a dormer, while a rooflight conversion suits roofs that already have generous height. Mansards are the rarity here. The honest answer comes from measuring your specific roof, which is what the free site visit is for.
Always. Building Regulations apply to every loft conversion whether or not planning permission is needed, covering the new structure (steels, joists), fire safety (a protected escape route, fire doors, linked smoke alarms), staircase design, headroom, insulation and sound separation from the rooms below. Arranging Building Control, through the council or an approved inspector, is the homeowner’s responsibility. We build to the required standards throughout and work with your inspector so every stage is checked and signed off properly.
