A red-hued extension built from brick and precast concrete has been added to Cast Corbel House in the suburbs of Norwich by Grafted.

Composite trim (can be all wood) is resistant to decay and can have either a smooth or textured surface. Stock and custom-made products are both available in most materials.

The living room, now used as an office, has a vaulted ceiling with custom corbels, open bay views, a wet bar and a marble surround fireplace with a wood mantel.
