Wall Panelling in London Renovations: Period Authenticity and Contemporary Approaches

Wall panelling is having a sustained moment in high-end London residential interiors. It appears in two very different contexts: as careful period restoration in Victorian and Georgian properties, and as a confident contemporary design statement in conversions and new builds. Both are legitimate; both require different approaches.

Here is how to think about panelling specification for each.

Period panelling: what it was and why it was there

Timber wall panelling in period London properties served practical and aesthetic functions simultaneously. At dado height (approximately 900mm from the floor), it protected plaster walls from impact and furniture. In formal rooms, full-height panelling — from skirting to cornice — was a signal of quality and expense, concealing irregular masonry behind a smooth, joinery-grade surface.

The panelling installed in Georgian and early Victorian townhouses used a small number of well-established profiles: fielded panels (with a raised central field surrounded by a moulded frame), bolection mouldings at the junction between panel and frame, and specific proportions that related to the room's overall composition — typically three or four panels across a bay width, with heights that related to dado and cornice positions.

Why the proportions matter: Period panelling looks right because it follows a set of proportional relationships that are derived from classical architectural principles. The width of the frame rail relative to the panel field, the height of the dado relative to the ceiling height, the relationship between the panel proportions and the room's doors and windows — these are not arbitrary. Panelling that has been designed without reference to these relationships reads as generic. Panelling that follows them reads as belonging to the building.

Restoring or reinstating period panelling

Where original panelling survives, it should be retained and restored. Common issues with original panelling:

• —Multiple layers of paint: Victorian panelling was painted regularly over many decades; the accumulated paint can obscure the profile of mouldings. Removal of paint layers (chemically or by hot-air gun) reveals the original profile and allows accurate refinishing.
• —Missing sections: Where panels or rails are missing, they must be replaced in matching profiles. Matching period moulding profiles requires access to a wide range of traditional profile cutters or a specialist joinery workshop that can machine a matching profile from an original sample.
• —Structural instability: Original panelling was often fixed directly to masonry with cut nails. Over time, fixings fail and panels separate from the wall. Structural re-fixing should be carried out before redecoration.

Where no original panelling survives but the property's character calls for it, new panelling in historically accurate profiles and proportions can be commissioned. The joiner should work from reference photographs of comparable period properties, not from standard modern profiles.

Contemporary panelling: design principles

Contemporary panelling in a renovation is a different proposition — it is not attempting period authenticity but using panelling as a formal design element. The contemporary vocabulary is different:

Flat panels with shadow gaps: Rather than moulded frames and raised fields, contemporary panelling uses flat MDF or timber panels with a recess (shadow gap) at the junction between panels. The shadow gap — typically 6–10mm — creates a visual joint without a physical moulding. The result is clean and geometric.

Full-height panelling: Contemporary interiors often run panelling from floor to ceiling rather than stopping at dado height. This creates a more complete, resolved enclosure. The detail at the ceiling junction (whether the panel meets the ceiling directly or has a capping profile) is a significant design decision.

Material variation: Contemporary panelling uses a much wider range of materials than period joinery: - Fluted or reeded timber panels: A timber panel with vertical or horizontal channels routed at regular intervals. Adds texture and rhythm. - Acoustic panels: Perforated or slatted panels with acoustic absorber behind, serving both decorative and acoustic functions. Increasingly common in home cinemas, studies, and living rooms. - Stone or tile panels: Large-format stone or tile used as a panelling element — in a bathroom, a bedroom headboard wall, or a formal fireplace wall. - Upholstered panels: Fabric-upholstered panels (typically linen, velvet, or leather over a foam padding layer) in bedrooms and studies. Warm, quiet, and highly decorative.

Colour: Contemporary panelling is frequently painted in a single rich colour — the same colour on the walls and the panelling — so that the panelling texture is visible but the surface reads as continuous. Alternatively, the panelling is in a contrasting colour or material to the surrounding walls.

Joinery specification for panelling

Regardless of period or contemporary application, the construction of panelling follows similar principles:

Carcass construction: Panelling is typically built on a structural timber or MDF framework (battens) fixed to the wall, with panel infills. The battens provide a fixing ground and a cavity behind the panels (which can be used for acoustic insulation or services).

Panel material: For a painted finish, MDF is standard — it takes paint extremely flat and is dimensionally stable. For a stained or lacquered finish, solid hardwood or hardwood-veneered MDF is required. MDF should not be used in wet areas without full sealing on all faces and edges.

Joints between panels: Shadow gaps between panels should be consistent in width — this requires precise manufacturing and setting out. A variation of more than 1–2mm across a run of panels is visible and undermines the quality of the installation.

Skirting and architrave integration: The skirting board at the base of the panelling and the architraves around doors should be coordinated with the panel design — ideally designed as part of the same scheme rather than specified independently.

What good panelling installation requires

Plumb and level walls: Wall panelling is installed plumb and level regardless of the wall behind. In a period property where walls are rarely truly plumb, this means the shadow gap or fixing depth varies. Good joiners manage this invisibly; poor joiners let the variation show.

Setting out before fixing: The panel layout should be set out fully on paper before any fixing begins. The position of every joint, shadow gap, and panel centre must be coordinated with doors, windows, electrical outlets, and any wall-hung items. Panelling installed without this planning produces joints that clash with door frames and shadow gaps at odd positions.

Finishing quality: In a painted installation, the quality of the final paint finish determines the perceived quality of the panelling. Moulded profiles must be cut-in cleanly; shadow gaps must be painted consistently; the paint surface must be flat and free of brush marks. This requires multiple coats and flatting between them.

ASAAN's approach

ASAAN designs and installs bespoke wall panelling as part of renovation projects across London. We work with skilled joiners who can produce period-accurate moulding profiles or contemporary flat panel systems to a luxury standard.
