We would like to introduce wood panelling to our 1800s townhouse.

Chris Dyson replies: Wood panelling has long been used as decorative cladding; at full height it covered uneven walls and helped insulate the house against the cold. In drawing rooms it would create a sense of proportion, control and warmth. On staircases and in halls, wainscoat panels to dado-height protected the lower half of the walls from wear and tear.

Panelling in older houses is often made of oak, but during the 18th century cheap and plentiful pine became more popular. The plain wood was not visible, but would have been painted in the muted colours available at the time. Faux wood graining techniques were also applied to imitate more expensive timbers such as mahogony, teak or burr walnut.

Today, solid-wood panelling is available from specialist companies, but I often opt for cheaper reconstituted wood, such as laminated pine, available from large timber merchants. These panels come in a variety of sizes and thicknesses, from 12mm to 24mm, in plain, recessed or raised and fielded styles.

Once painted, it's hard to spot the difference. Panelling can also be made into secret cupboards to disguise visually intrusive items such as televisions or bookshelves. This creates a cleaner look allowing the eye to rest on more important items such as paintings.
