What is a porch?

A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.

In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
We check this for your address before design work starts, so there are no surprises later.
