How much does a Hangar Home cost?

This would largely depend upon the cost of the site, which would vary depending on the location.  So as to reduce borrowing costs and minimise Stamp Duty Land Tax (SDLT), each plot will be sold and paid for before the unit is built, which would be settled by stage payments.  

The charge for each plot would cover a proportion of the site cost, SDLT, Community Infrastructure Levy (CIL), ground works for mains services (water, sewage and electric), access road and parking, concrete slab and aircraft hard-standing. This would mean that each owner would pay little or no SDLT, as none is required for the building because it would be a separate transaction.

As for the charge for each unit, it should be borne in mind that these are more expensive to build than a conventional detached house, not only because of the specific requirement for a steel frame and a 12m wide hangar door, but also because of the eco-friendly facilities.  Whilst the capital costs will be higher than a conventional detached house, the running costs will be much lower.
