Sequencing materials with the build programme
The right materials need to be on site at the right time for the build to keep moving. Lead times vary; some items are weeks, some are days.
Your build moves through phases. The materials each phase needs have to be on site by the time the work that uses them starts. Get the sequencing right and the build flows; get it wrong and the build stalls around a missing delivery.
How sequencing works
Your builder plans the build in phases — typically break ground, first fix, second fix, and finishing. Each phase needs different materials at different points. Your builder will tell you which items need to be on site by when, and the materials tracker shows the expected delivery dates against the programme.
A few common rhythms:
- Structural and rough-in materials (timber, plasterboard, copper pipe, electrical cable) need to be on site at first fix. Your builder usually orders these.
- Tile, sanitaryware, and bath/shower fittings need to be on site by the time second fix starts in the bathroom. You usually order these.
- Kitchen cabinetry and worktops need to be on site for the kitchen fit. Custom joinery has the longest lead times — sometimes many weeks.
- Light fittings, taps, switches, and handles can be later, but the build will get held up if they're not on site when the trades come in to install them.
Lead times that surprise people
A few items routinely take longer than people expect:
- Bespoke joinery — kitchen carcassing, custom wardrobes, vanity units. Multiple weeks of lead time, sometimes longer.
- Specialist sanitaryware and bath fittings — premium ranges, specialty finishes, commissioned glass.
- Tiles in unusual sizes or finishes — particularly handmade or imported tile.
- Bespoke worktops — stone, concrete, anything templated to your kitchen layout.
If any of these are in your project, get them ordered early. Your designer will usually flag them during the materials list stage.
What happens if a delivery slips
Sometimes a delivery slips. The article What to do if a delivery is missing or wrong covers the immediate path. The structural answer is that your builder usually has a few options to keep the build moving while a single delivery catches up — though if the slipping item is on the critical path, it can hold the project back.
What this means for you
Use the materials tracker. Order long-lead items early. Ask your designer or build advisor about anything that looks like it might be tight. The build flows when the materials are sequenced; one small surprise on a date can compound into a much bigger one if it isn't spotted in time.
