How Long Does It Take to Build a New House? A Realistic Timeline

One of the first things clients ask when planning a new home is how long it will take. The build itself is only part of the story – design and approvals often take as long as the construction. Here is a realistic outline of each stage.

1. Design and drawings

Working with an architect or designer to develop a layout and appearance you are happy with typically takes a few months, depending on how quickly decisions are made.

2. Planning permission

Once an application is submitted, councils in Northern Ireland aim to decide most local applications within a set target period, but complex or rural sites can take longer, particularly if further information is requested. It is wise to allow several months.

3. Building Control and technical design

Detailed construction drawings, structural calculations and Building Control approval can often run alongside the planning process.

4. Groundworks and foundations

Site clearance, drainage, services and foundations usually take a few weeks, depending on ground conditions and weather.

5. Building the shell

Walls, floors and roof bring the house to a wind- and watertight stage. For a typical detached home this is often a matter of a few months.

6. First fix, plastering and second fix

Plumbing, electrics, joinery, plastering, kitchens, bathrooms, flooring and decoration complete the interior. This is often the longest stage of the build.

7. External works and handover

Driveways, paths and landscaping are finished, final inspections are carried out and the completion certificate is issued.

What affects the timeline?

  • Size and complexity of the design
  • Ground conditions and site access
  • Weather during the groundworks and shell stages
  • Lead times on windows, kitchens and specialist items
  • Changes to the design once work has started
