The Piggery St.Albans – Hertfordshire

Executive Summary

The Piggery is located in St.Albans Hertfordshire and is a barn conversion & replacement project built using Thermohouse ICF.

The ground floor has an area of about 250 sqm.

First floor slab is about 120 square metres and appears like an island, as this floor is supported only by interior walls, which don’t touch any of the exterior walls. This was done to allow light from the big glazing openings on ground floor to cover the first floor area.

The properties first floor internal windows allow you to have an impressive overlook on the internal spaces, which includes the sitting area/play area/kitchen area on ground floor on the lower -800mm level.

There is a dual pitched roof, built using Thermoroof, which features many velux windows for optimum internal lighting.

How Thermohouse Helped

Because of planning restraints with maximum ridge height, the building’s  ground floor slab is approx 800mm under soil level. Slab is stepped with around 70% at this -800mm level and the rest at  terrain level.
