Bungalow rear extension in Hertford

How much does a bungalow rear extension cost in Hertford?

Guide prices for a bungalow rear extension in Hertford start from our East of England rate of £1,960–£3,180 per square metre, including VAT. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.

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 bungalow rear extension in Hertford?

Here is how the rules in England apply to a bungalow rear extension in Hertford.

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.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

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 Hertford like to extend?

Hertford mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

1. Look round and measure

   A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.
