The Pines Calyx St Margaret's Bay, Kent

Type of Development

An earth sheltered conference and functions venue. A highly innovative and unique building, consisting of two interconnecting roundels, partly two storey.

Constructed with rammed chalk (utilising the chalk excavated from the site) load-bearing/retaining walls and a shallow timbral vault roof construction.  Timbral vaulted roof construction originates in the Catalan region of Spain and this building was the first of its kind to be built in this country.

The building was recovered in soil and replanted to blend as harmoniously as possible into the landscape
