A home in Williamsburg with a bathroom that saw its original tin-panelled ceiling restored and intricate 19th-century plasterwork set within a modern apartment feature in this lookbook, which showcases decorative and ornate ceilings.

Mouldings are decorative architectural elements that are used as focal elements in interior spaces, contouring the corners of ceilings and light fixtures in the form of ceiling roses, cornices, architraves and coving.

These elements typically have a highly decorative and ornate finish incorporating seamless patterns, created through reliefs and recesses across their surfaces.

Mouldings and ornate plasterworks are typically associated with the Georgian, Victorian and Edwardian eras and were drawn from classicism and ancient Greek and Egyptian architecture.

The architectural elements were often constructed from plaster and timber, however the 20th century saw people look to alternative materials to obtain more durable and cost-effective finishes.

This is the latest in our lookbook series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring deliberately unfinished interiors, maximalist interiors and homes with walk-in wardrobes.
