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.
How much does a porch cost in Grimsby?
In Grimsby, a porch typically costs £6,250–£15,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the East Midlands run about 5% below the UK average, and the figures for Grimsby are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a porch in Grimsby?
The approval route for Grimsby is set by planning law in England. In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is over 3 metres high and it is at least 2 metres from a boundary next to a road.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
We check this for your address before design work starts, so there are no surprises later.

Questions about porches in Grimsby
Who approves a porch in Grimsby?
Planning matters in Grimsby go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Can you move the gas or electric meter?
Meters belong to the supplier or network operator. We coordinate their move as part of the job, which can add time.
Does a porch need building regulations?
In England and Wales a ground-level porch under 30 square metres is usually exempt if the front door stays in place and the glazing meets safety standards. In Scotland the exemption is much smaller (around 8 square metres, with no new opening into the house). If the front door is removed, approval is needed. We check this for your design.
