External & Fire Escape Staircases Chichester
Heritage-sensitive external staircases for Chichester’s historic city centre, Conservation Area homes and harbour-side properties — plus BS 9991:2024 documented fire escapes for HMOs, converted flats, commercial premises and mixed-use buildings. EN 1090-1 EXC2 certified steel, designed for planning sensitivity, Building Control and long-term durability.
Chichester installations — heritage residential, harbour-side access and commercial fire escape
How much does an external or fire escape staircase cost in Chichester?
Residential external staircases start from £3,500 for garden access; heritage-sensitive, harbour-side or Conservation Area configurations typically run £6,500–£12,000+ depending on finish, fixing strategy and planning requirements. Commercial fire escape staircases start from £6,500 for HMO or converted-flat two-storey escape routes, with larger multi-storey installs from £12,500.
Are you compliant for HMOs, flats, commercial buildings and mixed-use properties?
Yes — every Continox commercial fire escape is documented to BS 9991:2024 and Approved Document B, with stair geometry, landings, guarding, structural calculations, UKCA marking and EN 1090-1 EXC2 manufacturing documentation prepared for Building Control, insurers and property managers.
Can you design for heritage, Conservation Area and harbour-side locations?
Yes. Chichester projects often need a balance between practical access, heritage appearance and structural performance. We can prepare discreet rear-elevation designs for city-centre properties, corrosion-resistant specifications for harbour-side villages, and Building Control-ready fire escape designs for commercial or multi-occupancy buildings.
Historic-city design meets modern fire escape compliance
Chichester’s external staircase market is shaped by a very different mix from larger coastal cities. The historic city centre, Conservation Areas, listed buildings and Georgian or Victorian residential streets demand sympathetic external design, while commercial buildings, converted flats and HMOs need properly documented fire escape compliance. Around Bosham, Fishbourne, Dell Quay, Birdham and Itchenor, harbour-side exposure also makes corrosion protection and wind loading part of the brief.
Continox handles both sides of that brief. The engineering standard stays the same, but the visual finish, fixing strategy, planning support and compliance documentation change depending on whether the project is a private home, listed property, HMO, commercial unit or harbour-side installation.

Six system types — engineered for Chichester’s historic and harbour-side stock
Each system is dimensioned, structurally calculated and finished for its specific use case. Chichester’s distinctive mix of historic city-centre properties, Conservation Areas, harbour-side villages and commercial estates means each system gets configured differently from a standard inland installation.
Heritage-Sensitive Black External
RAL 9005 deep-black powder coat over hot-dip galvanised. Discreet rear-elevation design, slim steel profile and sympathetic RAL finish over galvanised substrate. The defining premium specification for Chichester city-centre, Summersdale, Westgate, Eastgate and Conservation Area residential projects.
Galvanised Fire Escape
Hot-dip galvanised throughout — standard for Chichester HMOs, converted flats, rear commercial escape routes and mixed-use buildings. Documented to BS 9991:2024 and Approved Document B. Insurance and Building Control pack ready.
External Spiral
Space-saving spiral, ⌀1400–2200mm diameter. Common Chichester specification for compact rear gardens, courtyard access, roof terrace links and tight historic plots where a straight flight will not fit.
Industrial Mezzanine
BS 5395-3 industrial stair for warehouse mezzanines and light industrial premises — applicable across Chichester’s commercial areas including Terminus Road, Quarry Lane, Portfield and Tangmere.
Garden Platform Access
Galvanised steel platform staircase for raised gardens, split-level homes, rear extensions and stepped plots around Summersdale, Lavant Road, Fishbourne and nearby villages. Built around the actual ground conditions and fixing points found on site.
Basement & Rear Service Access
Below-ground external steel staircase for basement plant rooms and commercial cellars. Relevant for Chichester city-centre commercial premises, plant rooms, lower-ground service access and converted commercial-to-residential stock with retained rear access.
The four standards that govern your installation
External and fire escape staircases sit at the intersection of four British and European standards. For Chichester HMOs, converted flats, commercial premises and mixed-use buildings, documentation is not an afterthought — it is what Building Control, insurers and property managers often need to see. Continox documents the relevant standards as standard.
Residential fire safety design — the 2024 update
BS 9991:2024 is the updated code of practice for fire safety design of residential buildings, replacing the 2015 edition. The 2024 revision tightens external escape route requirements, clarifies single-stair building provisions, and aligns with the Building Safety Act 2022 regime.
For Chichester HMOs, flats and converted buildings, the key implications are documented external escape routes where internal escape is restricted, clear stair geometry, suitable landing provision, guarded edges and traceable compliance documentation. Every Continox fire escape includes a design statement referencing the applicable requirements.
Statutory fire safety — what Chichester Building Control checks
Approved Document B is the statutory guidance for compliance with Part B of the Building Regulations. Building Control checks fire escape designs against Approved Document B Volume 1 or Volume 2 depending on building use, with HMOs, flats, mixed-use buildings and commercial premises requiring particular attention to escape route geometry and travel distance.
| Building Type | Max travel distance |
|---|---|
| HMO bedroom to stair | 9m one-direction |
| Converted flats common area | 7.5m one-way |
| Commercial / office sprinklered | 18m one-way |
| Office (unsprinklered) | 12m one-way |
Industrial stairs — mezzanines & commercial premises
BS 5395-3 covers industrial stair design, permanent ladders and walkways. It applies to mezzanine staircases, plant access, and most commercial back-of-house installations — including workshops, storage units and light-industrial premises around Terminus Road, Quarry Lane, Portfield and Tangmere.
Key requirements documented in every Continox industrial install: maximum pitch (38°), minimum tread depth (175mm), going (250mm minimum), and handrail/balustrade configuration for industrial use. Each install ships with 5395-3 compliance documentation.
Structural steel certification — the insurer-trust standard
BS EN 1090-1 is the harmonised standard for execution of structural steelwork. EXC2 is the execution class required for the majority of staircase and fire escape installations.
Continox's production facility near Kraków holds EN 1090-1 EXC2 certification in-house — meaning we issue a Declaration of Performance and UKCA marking with every supply. This is documentation many smaller fabricators sub-contract or cannot provide directly. For Chichester commercial property operators, it's a clean audit trail for Building Control, commercial insurers, landlords and property managers.

Why Chichester needs a heritage-and-compliance staircase brief
Chichester combines a historic cathedral city, dense Conservation Area settings, listed buildings, harbour-side villages and practical commercial estates. A correct external staircase here needs to do more than meet dimensions: it must respect the building, survive the local environment and provide the right documentation for Building Control, insurers or property managers where required.
Historic core — discreet design & planning sensitivity
Chichester city centre, the streets around the Cathedral, the City Walls and the wider Conservation Area require external staircases that look deliberate rather than temporary. Rear elevations, fixing positions, balustrade detail and colour all matter. Continox designs these staircases around discreet fixing, sympathetic finish and planning-supporting information where needed.
HMO, flats & commercial compliance
Chichester’s converted homes, flats above shops, HMOs and mixed-use buildings can all require clearly documented means of escape. Where an external fire escape is required, the staircase must be more than a fabricated structure — it needs stair geometry, guarding, landings, structural calculations and Building Control-ready documentation.
Harbour villages — corrosion protection & visual restraint
Bosham, Fishbourne, Dell Quay, Birdham and Itchenor introduce a different brief: coastal air, exposed gardens and sensitive landscape settings. Hot-dip galvanising, marine-grade coating and visually restrained detailing are often more important than a standard painted finish. We specify the finish to the actual exposure.
Conservation Areas, listed buildings & consent routes
Many Chichester projects sit near listed buildings, Conservation Areas or sensitive historic streets. External alterations may need planning advice, listed building consideration or a carefully justified design. Continox can provide drawings, finish information and design notes to support the consent conversation before manufacture.
Commercial estates & rear access constraints
Terminus Road, Quarry Lane, Portfield and Tangmere generate a practical staircase brief: mezzanine access, plant access, external rear escape and service stairs. These projects are usually less about visual heritage and more about load rating, safe access, compliance documentation and low-maintenance galvanised construction.
Raised gardens, rear extensions & compact plots
Chichester and nearby villages include many compact rear plots, raised gardens and older extensions where a standard straight flight does not fit easily. We design around the actual access route, party walls, drainage, door thresholds and platform requirements so the finished staircase works with the property rather than against it.
