How much does a terraced house rear extension cost in Prescot?
For Prescot we work from the North West England rate: £1,930–£3,100 per square metre of new floor, including VAT, standard specification. North West prices sit below our West Midlands baseline; access on terraced streets is the main variable.

| 3 m wide × 6 m deep (18 m²) | £34,500–£56,000 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a terraced house rear extension in Prescot?
Here is how the rules in England apply to a terraced house rear extension in Prescot.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Prescot like to extend?
Stone and brick terraces are common around Prescot. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
