Do you need planning permission for a terraced house rear extension in Boston?

Here is how the rules in England apply to a terraced house rear extension in Boston.

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 Boston like to extend?

Red-brick terraces and semis are typical of Boston. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

How a terraced house rear extension in Boston comes together

  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.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Terraced house rear extension questions in Boston

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Is the site visit in Boston free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

Do both neighbours need party wall notices?

Usually yes in England and Wales, because the extension often sits on or near both boundaries.

Do you handle building control in Boston?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Do I need planning permission for a rear extension in Boston?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
