Small Projects

Garages, Extensions, Outbuildings etc.

Using ICF for a small construction project allows you to build a quality structure very quickly.


PolyBlok ICF is ideal for building small structures that need to be enclosed and covered like music srudios for practice or recording, garden offices, sheds or garages.

Can be self-built as they don’t require specialist labour.
Can be built in gardens with limited access.
Quick and easy to put together.
Can be faced with timber to blend into the garden landscape.

Extensions and Outbuildings.


Extensions can transform a small house that is too small for a growing family into one that is just right, without the cost and hassle of moving, and at the same time add value to the property. The Permitted Development Rights also often allow large extensions or outbuildings to be built without the need for planning consent,

ICF Polybloks are ideal for this type of project because they:

Can easily be connected to existing walls by bolting wall ties to the house walls.
Can be built 2 stories with very little risk of cracking caused by differential settlement.
Are ideal for self builders who need to waterproof quickly.
Can be built in gardens with limited access.
