Highly efficient new build using our unique NIPPs system.


Naturally Insulated Passive Panels

As a result of our involvement in delivering green, sustainable building solutions to our clients over many years we have developed a highly efficient and sympathetic natural material based prefabrication system for those clients wanting to minimise their environmental impact and reduce their construction costs.


Our NIPPs can be used as structural components or as additional insulation. They are highly thermally efficient and can be used as part of a passive house project


The materials used in our NIPP's are carefully selected not only for their technical performance but to reduce their environmental impact.


Our NIPPs are prefabricated, either offsite or onsite. They considerably reduced the onsite building phase.
