RICS Level 2 Survey in BN1

Three-quarters of Brighton and Hove's buildings were constructed before 1919. Within BN1 - covering central Brighton, Preston Park, Withdean, Coldean, and the Hollingbury area - this pre-1919 proportion is reflected in the terraced streets of Victorian brickwork that form the backbone of the housing stock. These properties were built with traditional materials and methods that require informed maintenance to remain sound: lime mortar, timber suspended floors, solid brick walls, and lead roofing details that behave very differently to modern construction.

Victorian terraces in BN1 were constructed with soft lime mortar in the joints between bricks. This mortar is deliberately weaker than the brick itself - it is the sacrificial element that allows the wall to breathe, releasing moisture through the joint face rather than allowing it to saturate the brick. When cement mortar is used for repointing - as it frequently has been during 20th-century maintenance cycles across Brighton - this balance is disrupted. Moisture becomes trapped within the brick, causing spalling, internal damp, and, in severe cases, structural deterioration of the masonry. Our inspectors check every external elevation for evidence of hard cement repointing and flag the affected areas in the survey report.

External timber joinery in Brighton's period terraces is a consistent source of maintenance liability. Sash windows, bay window frames, door surrounds, and exposed eaves boarding all require regular painting to remain watertight. Where paint has broken down and repainting has been deferred, moisture enters the timber and wet rot develops - sometimes invisibly behind intact paint surfaces until the timber has become structurally compromised. Surveyors probe accessible external timbers and check for soft spots, particularly at sill junctions, lower rail sections, and the base of door frames.

Ground floor suspended timber floors in BN1's terraced stock present a specific risk when the sub-floor void is poorly ventilated. Victorian building standards assumed a ventilated void beneath the ground floor boards, maintained by airbricks in the external walls at low level. Where airbricks have been blocked - by raised external render, buried paths, or deliberate sealing - moisture accumulates in the void and dry rot can establish itself in the floor joists. Our survey includes inspection of the sub-floor void where access is possible and checks the condition and openness of all airbricks visible from the exterior.

• Cement repointing condition on all external brick elevations
• Spalling brickwork and eroded mortar joint profiles
• External timber condition at sills, frames, and eaves boarding
• Ground floor airbrick openness and sub-floor ventilation
• Chimney stack and flaunching condition
• Roof covering, flashings, and gutter falls
• Damp meter readings at ground and first floor wall surfaces
• Condition of bay windows and any structural bay supports

The West Hill Conservation Area falls within BN1 and represents one of Brighton's designated zones of architectural and historic significance. Buying within a conservation area means that planning restrictions apply to external alterations - replacement windows, extensions, and changes to roofing materials all require specific consent. Our survey identifies conservation area status for properties in BN1 and notes any external alterations that appear to have been made without the necessary approvals.

Brighton has a high concentration of Grade I and Grade II listed buildings within and around BN1, particularly in the Regency squares and the Victorian terrace streets closer to the city centre. Listed building status carries additional responsibility for owners: alterations to listed properties require Listed Building Consent, and repairs must use materials consistent with the original construction. Inappropriate repairs - such as cement repointing on a listed brick or flint building - can themselves constitute a breach of planning law.

Buyers considering listed properties in BN1 should be aware that a RICS Level 2 survey is generally appropriate for unlisted stock in reasonable condition, but Grade II and above listed properties often warrant a Level 3 building survey that provides the greater investigative depth required for a building subject to heritage controls. Our team advises on the appropriate survey level based on listed status and condition, and has experience with the specific defect profiles of Regency and early Victorian construction in the Brighton area.

Planning history searches conducted by your solicitor will reveal any enforcement notices, listed building consent applications, or conservation area approvals relevant to the property. Where our survey identifies alterations - converted loft spaces, removed chimney breasts, replaced windows - we recommend that your solicitor verifies the planning status of these works before exchange. Unauthorised alterations in conservation areas can require reversal at the new owner's cost.
