Construction methods

Timber frame, SIPs, ICF, masonry, a plain-English guide to the main build systems.

How to choose a construction method

Your choice of construction method will shape almost every other decision in your project, from the design of your home, to the contractors you appoint, to the mortgage products available to you.

There is no single “best” method. The right choice depends on your:

  • Budget. Some methods cost more upfront but save on labour; others are cheaper per square metre but slower to build.
  • Design ambitions. Some systems are better suited to open-plan layouts or unusual shapes; others are most efficient with simple, rectangular plans.
  • Site. Precision-engineered systems demand near-perfect foundations. Wet systems like brick and block are more forgiving.
  • Build programme. Offsite-manufactured systems can be erected on site in days; traditional wet construction takes much longer.
  • Your level of involvement. Some systems lend themselves to self-build labour input; others require specialist contractors throughout.

Talk to your architect early about which methods are appropriate for your design and site, and check that your chosen mortgage lender is comfortable with your chosen system, particularly if you are using a less mainstream method.

The exterior appearance of your home gives little clue about the construction method underneath. Timber frame, SIPs, and ICF homes can all be clad in brick, render, tile, or stone, the structural system is independent of the aesthetic.
