4 January 2027 + 138 weeks = 27 August 2029. Phases run one after another; the spare weeks sit at the end.

You have 8 weeks for delays after the planned work ends on 2 July 2029. Longer delays would push move-in back.

How this is worked out
  • Phases run one after another, each starting the day the last ends. Some work can overlap, such as design and buying the site. This planner adds all the weeks; ask your team for a separate schedule if phases will overlap.
  • For the planning phase use the planning decision date tracker once you have submitted your application. A request for more information or an appeal can add months. The figures here are your own allowances, not predictions.

Notice timing follows the National Building Control Office’s guidance. Meet planning conditions and building-control requirements before starting work.
