Building-site access: plan the deliveries before closing off the route

How to discuss construction access with your builder, trace a delivery through the site and identify when the developing house could block the route still needed.

A driveway on the finished site plan tells me where a car will go once the house is complete. I would also want to know how the materials for that house will arrive while it is being built. My starting question is simple: what needs to get through, and what will already be in the way when it arrives?

Key points

  • Discuss access with the builder and relevant delivery specialists while design choices are still open.
  • Trace materials from arrival to installation, including where they will wait.
  • Check the route again at the stages when walls, scaffolding or landscaping change the available space.
  • Record unresolved access decisions before ordering items that depend on them.

Follow one awkward item all the way in

I would choose a proposed item that looks awkward to deliver, such as a large window, and ask the builder to talk through its journey. Where does the delivery stop? How does the item reach its installation position? Can it go straight in, or does it need somewhere suitable to wait?

Getting through the gate answers only part of that question. For a hypothetical rear addition, the delivery might reach the front driveway easily while the final route depends on an opening through the existing house. I would ask the team to test that route before the window order and construction sequence are settled.

  • What delivery and handling information does the supplier need?
  • Which dimensions or site conditions still need checking?
  • Who will confirm the proposed route and installation method?

Draw the site at different stages

Take three copies of the site plan to a discussion with your builder: one for early ground works, one for the main structure and one for the finishing stages. Ask them to mark the expected working arrangement on each. Include temporary facilities and storage, rather than showing an empty plot around the house.

Then look for the moment a useful route disappears. Perhaps scaffolding occupies the side passage, a new wall closes an opening, or the completed entrance landscaping takes over the only unloading space. Ask what still has to arrive after that moment.

The answer might involve a different sequence, a different delivery arrangement or a design adjustment. I would want those options compared before assuming the team can sort it out when the lorry turns up.

  • Which installation needs to happen before a route closes?
  • What needs to be moved or removed between stages?
  • How will the final delivery and removal of temporary equipment happen?

Have the team assess the working arrangement

WorkSafe's guidance on work site traffic recommends separating pedestrian and vehicle routes. I would ask the builder how that will work here, including anyone using a shared entrance and people visiting the site. A homeowner's sketch is a way to raise questions; the businesses carrying out the work need to assess and manage the actual operations.

If a proposed delivery relies on the road, footpath or neighbouring land, mark that dependency clearly and ask who will check the necessary arrangements and permissions. I would not treat nearby empty space as part of the construction site simply because it looks convenient.

Keep access decisions beside the order list

I would keep a short list of items whose delivery arrangements remain unresolved. Beside each, record the question, who is checking it and which decision depends on the answer. That gives the next meeting something specific to resolve.

Ask the builder to explain any allowance for temporary access, handling, storage and making good afterwards. When comparing alternatives, ask what changes in the work and programme as well as the price. A cheaper product is not a useful comparison if its delivery assumptions are still unknown.

If you are preparing a home project, bring your site plan and the parts of access you are unsure about to an initial conversation. We can discuss which design questions to resolve with your builder before the route becomes fixed.
