What type of ground floor should you install in your extension?

Chris Brookman

Will it be:-

  • Suspended timber?
  • Suspended concrete (beam and block)?
  • Solid floor?

If you are well above ground level or if there are issues with water around you we would suggest a timber suspended floor or a beam and block suspended floor. Timber suspended floors would be the most sustainable option but do not carry the kind of loads that a solid floor can carry so if you have large open spaces, this may not be the best option. 

Solid floors are simple to install if the ground levels are correct but we would suggest you consider using more sustainable options such as foamglas for the insulation which can also mean you don’t need a concrete slab to build the floor off of.
