Before you buy a plot

  1. Make sure the plot is a plot with planning permission. Cheap land is often rural land where you cannot build a home.
  2. Look up the plot’s planning history on the council’s planning portal, and ask for pre-application advice if there is no permission yet.
  3. Check the utilities at the plot boundary: water, electricity and sewer. Ask each supplier for a connection quote before you sign.
  4. Check access. Modular homes arrive by truck in large modules and are set in place by crane: road width, bends, slope and space for the crane all matter.
  5. Get a soil study before final pricing. The foundations, and their cost, depend on the ground.
  6. Ask about setbacks, rights of way and flood risk. They limit where the house can go on the plot.

Permits for prefab and modular homes in the UK

  • A new home needs planning permission from the local planning authority, and separately Building Regulations approval. Modular and prefab homes follow the same rules. Source
  • A full planning permission normally lapses if work has not started within 3 years. Check the date and conditions on any plot sold “with planning”. Source
  • In England, join your council’s self-build register (Right to Build). Councils must grant permission for enough serviced plots to meet the demand on it. Source
  • Self-builders can be exempt from the Community Infrastructure Levy (CIL), but must apply and get the exemption before work starts. Source
