It is a common misconception that it’s very expensive to self build. Large, high-spec self builds will come at a premium, but the following projects all have build costs of £100,000 and under.

Please note: We’ve not included the plot price in these build costs – plot costs vary so wildly depending on location, and the plot circumstance varies between these projects defeating the object of comparison.

What factors affect build cost?

  • Location: land costs and labour costs can vary depending on location
  • Size: bigger houses will cost more to build (although two storeys will reduce the cost per m² of foundations and roofs)
  • Shape and layout: simple and square is the most cost-effective option
  • Chosen specification: high-end products will understandably eat up your budget
  • Involvement: the less involved you are, the more expensive the process will be
