Dunstable runs into Luton as one continuous built-up area, but it is a different job in almost every way that matters to a builder. It is a different planning authority, it is a different set of housing eras, it sits on a different part of the chalk, and since 2018 it has had a lorry restriction through the middle of it that changes how materials get to a site.

Start with that last one, because nobody mentions it and it costs people money. The A5 through Dunstable was de-trunked in 2018 after the A5 to M1 link and the new M1 junction 11A opened, the road through the town became the A5183, and a 7.5 tonne weight limit now covers most town centre roads. There are exemptions for access and delivery and for certain building and maintenance purposes, but it is something to plan a skip, a ready-mix wagon or a crane around rather than discover on the morning.

Then the authority. Dunstable is Central Bedfordshire, which became a unitary on 1 April 2009, and it also has a town council, which Luton does not have at all. The plan is the Central Bedfordshire Local Plan 2015 to 2035, adopted 22 July 2021, and the design standard is the Central Bedfordshire Design Guide SPD adopted 1 August 2023. None of those documents applies to a job four miles east in Luton.

Why Dunstable is a different build to Luton

Because the constraints sit in different places. Dunstable's town centre is inside a conservation area, designated in 1976 and covering just over 28 hectares with 53 listed buildings in it, whereas Luton's town centre conservation area is much smaller. But Central Bedfordshire has no Article 4 direction anywhere in Dunstable or Houghton Regis, so householder permitted development rights are intact even inside that conservation area, unlike Toddington and Husborne Crawley where they are not. And the Metropolitan Green Belt and the Chilterns National Landscape both start on the Downs side of town, which is a live constraint here and does not exist inside Luton borough at all.

Questions from Dunstable homeowners

Does the 7.5 tonne weight limit affect my building work in Dunstable?

It can affect deliveries rather than the work itself. Since the A5 through the town was de-trunked in 2018 and became the A5183, a 7.5 tonne limit has applied to most town centre roads, with exemptions for access and delivery and for certain building and maintenance purposes. In practice it means the route and the timing for skips, ready-mix and larger plant get planned in advance instead of assumed. It is one of the reasons a builder who works in Dunstable regularly is worth more here than one who does not.

Do I need planning permission for an extension in Dunstable?

Central Bedfordshire Council is your planning authority, not Luton. Many rear extensions are permitted development, and helpfully there is no Article 4 direction anywhere in Dunstable or Houghton Regis, so householder rights have not been removed even inside the town centre conservation area. That conservation area is still a real constraint on appearance and materials, and if you are up on the Downs side you may also be in the Chilterns National Landscape or the Green Belt, where the Chilterns Buildings Design Guide applies. We establish which of those you are in before anything is drawn.

What is the ground like in Dunstable?

Chalk, but a different part of the sequence to most of Luton. The Downs are Middle or White Chalk sitting on Lower or Grey Chalk, with West Melbury Marly Chalk and Zig Zag Chalk underneath the town. Running through the Lower Chalk is the Totternhoe Stone band, a hardened seam up to about five metres thick that forms the spur the town sits on. Dunstable has no river at all, which is why the town historically took its water from deep wells on Half Moon Hill through 200 to 450 feet of chalk. Foundation depths follow the NHBC minimum of 450mm against frost, with the real questions being dissolution features and local variability rather than shrink and swell.

Can you work with Totternhoe stone?

Totternhoe Stone, or clunch, is the local hard chalk that was quarried at Totternhoe from Roman times, passed to Dunstable Priory in 1131 and worked until around 1925. It is soft when it comes out and hardens as it dries. The thing to know before you use it externally is that it absorbs roughly 15 per cent water and weathers badly, and the west front of Dunstable Priory is the textbook example of what that looks like over time. If you have clunch on your property, tell us at the survey, because the repair approach is not the same as brick.

Which parts of Dunstable do you work in?

All of it, plus Houghton Regis and the villages. The Watling ward on the Downs side is the detached and owner-occupied end of town, at 27.5 per cent detached and 78.9 per cent owner occupied in the 2021 Census. Icknield is heavily semi-detached at 56.4 per cent. Northfields, where the borough council finished its estate in 1935, has the highest terraced share at 29.2 per cent. Different housing, different jobs, same team.

Do you work on the newer estates around Dunstable and Houghton Regis?

Yes. The former AC Delco site in Dunstable is now housing, with the streets named after car makers, and Houghton Regis North is still being built out at Linmere, where outline permission in 2014 allowed up to 5,150 homes across 262 hectares. Newer houses need a different eye to Victorian ones: trussed roofs make loft conversions more expensive, and warranty and estate management conditions can affect what you are allowed to alter.

Is Dunstable the same as Luton for planning?

No, and treating them as one place is the commonest mistake we see. Dunstable is Central Bedfordshire and has a town council. Luton is a unitary authority with no parish tier. They have different local plans, different design guidance, different conservation area boundaries and different Article 4 positions. One more that catches people out: Houghton Regis, not Dunstable, was the London overspill town under the New and Expanded Towns Scheme, growing from under 3,000 people in 1951 to 10,490 by 1971.
