Managing a Self-Build: Working with Your Bricklayer from Foundation to Ridge

7 March 2026 by Michael Swan 2 min read

Self-builders who communicate clearly with their bricklayer, stock materials ahead, and lock in decisions early avoid the delays that derail programmes.

Self-building gives you control over every detail of your home. It also gives you every headache that a main contractor would normally absorb. On brickwork, the relationship between the self-builder and the bricklaying team determines whether the build runs smoothly or stalls at the most expensive phase.

Before a Single Brick Is Delivered

Get the full set of architectural and structural drawings to your bricklayer at least two weeks before the planned start date. This includes the brick schedule, the structural engineer is beam and foundation calculations, and the window and door schedule. If the window manufacturer is lead time is eight weeks, order them before brickwork starts, not when the openings are formed.

Brick supply is the other common bottleneck. Order bricks early. Popular facings from Ibstock and Wienerberger can have 4 to 6-week lead times. Order the full quantity in one batch from the same production run to ensure colour consistency, plus 5% overage for cuts and breakage.

During the Build

Keep materials flowing. A bricklaying pair can lay between 400 and 600 bricks per day on straightforward work. At that rate, a single-storey extension consuming 3,000 to 4,000 facing bricks will use a full pack (roughly 400 to 500 units) per day. Running out at 2pm on a Friday is expensive; the team cannot work, but you are still paying for scaffold hire and site overheads.

Communicate changes immediately. If the architect revises an opening width or the structural engineer changes a lintel specification, tell the bricklayer before the wall reaches that point. Dismantling and rebuilding is never free.

Quality Checks You Can Do Yourself

Use a spirit level to check plumb at every pier and opening reveal. Count the wall ties; there should be one every 900mm horizontally and 450mm vertically. Check that the cavity is clean by looking down between the leaves before the wall plate goes on. Read our quality inspection guide for more detail.

Frequently Asked Questions

The structural engineer calculates this based on the span, the load above (roof, floor, wall), and the bearing conditions. A typical rear extension opening uses a 152 x 89 or 203 x 133 UB section.
A dense concrete or engineering brick block placed at each end of a steel beam to distribute the concentrated load into the brickwork or blockwork below. Without adequate padstones, the beam can crush the masonry.
The walls are built to the beam bearing height with padstones in place. The beam is lifted in (manually or by crane), checked for level, then the brickwork continues above and around it.
Internally, beams are typically boxed in with plasterboard. Externally, the beam end may be concealed behind the facing brickwork with a brick slip lintel facing applied to the visible face.
A typical extension beam costs 200 to 600 for the steel itself, plus 200 to 500 for delivery, crane hire, and installation. The brickwork to support and conceal it is part of the overall brickwork cost.
