Taking out a load bearing wall means replacing what the wall was doing with a beam and its bearings. The sequence is survey, engineer's calculations, building control application, propping, wall out, steel in, making good, sign off. We appoint and coordinate the structural engineer and build to the calculations issued. We do not produce structural calculations ourselves. This page sets out what that looks like on a Dunstable property.
Central Bedfordshire needs plans, specifications and structural calculations before the wall comes out
A full plans building regulations application to Central Bedfordshire Council must include detailed plans, specifications and structural calculations. That is why the engineer is appointed before anything is opened up rather than after. We commission the calculations, submit the application, and keep the drawings and the built work matching each other.
The council does not publish a fixed list of inspection stages either. The stages you must notify are set out instead in the inspection service plan issued for your job. We read that plan at the start and build the programme around it. The propping, the bearings and the beam are each notified when the plan says, not once the wall is already closed up.
West and south west Dunstable sit on a different chalk from the town centre
British Geological Survey 1:50,000 mapping gives the New Pit Chalk Formation around Whipsnade Road, Spoondell and Royce Close, rather than the Holywell Nodular Chalk of the town centre. The BGS describes New Pit as principally blocky, white, firm to moderately hard chalk with numerous marls or paired marl seams. Marl seams are the softer bands, and they matter directly under a bearing.
There is a second reason not to assume good ground on that side of town. The Bedfordshire Geology Group records Spoondell Quarry, once worked for whiting, as now a housing estate in Dunstable. Where a bearing point lands on ground with that history, the engineer designs from what a trial hole actually shows rather than from the map.
Walls in central Dunstable can be clunch as well as brick
Council tax records count about 560 homes built before 1900 and about 620 built between 1900 and 1918 in the Dunstable Central area, the highest pre 1919 counts of the town's five areas. Totternhoe stone pit, west of Dunstable, is the only producer of Totternhoe Stone, a chalk hard enough to be worked in any direction and known to masons as a freestone. That stone is soft compared with brick.
A steel puts a point load where a solid wall spread a line load. So the padstone size, and what the padstone bears into, are the engineer's decision, taken once the wall is opened and the fabric is visible. We open up carefully, record what is there and stop for the engineer rather than guessing.
Council tax records count about 1,380 homes built between 1955 and 1964 in Dunstable East alone
That is out of about 2,780 homes in that area, on Valuation Office Agency figures. Houses of that period have a recognisable plan: a front room, a back room, and a spine wall between them carrying the floor above. The spine wall is the one people want out, and it is load bearing.
The work is the same in principle whatever the period, but the detail changes. A house of that age has thinner inner leaves and shallower foundations than a Victorian terrace, so the bearing at each end is the question rather than the beam itself. The engineer sizes both. We build to what is issued and book the inspections around it.
- Building control notification and inspection sign-off
- Assessment of whether a wall is load-bearing
- Joist ends supported where the wall carried the floor above
- Dust screens and floor protection through occupied rooms
- Temporary propping, needling and staged demolition
Trusted Load-Bearing Wall Removal in Dunstable
The order matters more than anything else on a wall removal. We survey, appoint the structural engineer, submit the full plans application to Central Bedfordshire Council with the calculations, then prop, then open up. Nothing comes down before the steel is on site and the props are in. You get one point of contact for the engineer, the steel, the brickwork and the sign off, and the calculations are always the engineer's, because we are a contractor rather than an engineering practice.
