Panelling That Looks Architectural Rather Than Applied

Panelling is proportion. Get the setting-out wrong and no finish will rescue it. The points below are written in the order we would actually raise them on site, because the order usually matters as much as the content — a decision made two steps too late is often no longer a decision, just a repair. Panelling is proportion. Get the setting-out wrong and no finish will rescue it. None of what follows depends on style or budget tier; it applies whether the room is being done on a tight number or a generous one. What changes with budget is the material, not the sequence of decisions. Panelling is proportion. Get the setting-out wrong and no finish will rescue it. Treat each point as a check rather than a rule — the right answer depends on your room, and the value here is in knowing which question to ask before a decision becomes expensive to reverse. This is written from projects rather than from a general principle, which is why it names specific dimensions and specific failure modes rather than staying at the level of advice. Where your own room differs from the assumption behind a point, the point still applies — just adjust the number. Nothing here requires taking our word for it; each point is the kind of thing you can verify yourself on a site visit or ask a contractor to confirm in writing. That verification is usually the difference between advice that gets followed and advice that gets nodded at and ignored. A few of these points contradict what gets repeated as conventional wisdom. Where that happens we say so directly and explain why, because the conventional version is usually true in general and wrong for the specific case it gets applied to.

It is easy to treat this as a minor decision because it does not show up in a rendered image. In practice it is one of the decisions that determines whether the finished room actually works the way it was intended to, independent of how it looks. Where any of this does carry a cost, it is usually smaller before installation than after. A change raised at the drawing stage is a line on a plan; the same change raised after the trades that depend on it have moved past it is a demolition and a delay. The right moment to act on any of this is whichever comes first: the design drawing that fixes it, or the trade on site that executes past it. After either, changing course gets progressively more expensive. This matters more than it looks like it should, because the cost of getting it wrong is rarely visible until much later — usually at the point where fixing it means undoing finished work rather than changing a line on a drawing.

Set out from the room, not from a standard

Panel widths should divide the wall evenly, with the end panels never narrower than the field panels. Draw the elevation before anyone cuts a moulding.

Respect the dado and picture rail heights

Dado at roughly a third of the wall height, picture rail at roughly four-fifths. Those proportions come from rooms that work and they still do.

Return the detail at openings

Panelling that stops awkwardly beside a door or window is the giveaway. Plan how it meets every opening and every corner.

Keep the moulding profile consistent

One profile through the whole home, scaled up or down. Mixing profiles between rooms reads as a series of separate decisions.

Paint it in one colour

Panelling picked out in a contrasting colour draws attention to the joints. A single colour in two sheens gives depth without fragmenting the wall.
