If these analyses determine that a lime mortar was used originally, the building should be repointed using a lime mortar, preferably made with lime putty
Traditional skills are being utilised in the restoration including oak lath and three-coat fibrous lime putty
plaster to ceilings, two-coat fibrous lime putty
plaster to walls, fibrous plaster mouldings and cornices, traditionally made cast-iron windows, purpose made cast iron gutters, lead-lined valley gutters and replacement king posts and dragon ties to the roof structures.

About 180 tonnes of sub-soil from a Shropshire quarry will be used for the walls which will then be made weather-proof with lime putty

Traditional techniques such as lime putty
pointing are being used.
The logic for the soft lime putty
mortar used throughout the building is to do with limiting long term movement.
The best answer to cure dampwalls is to apply a lime putty
render (with stone dust aggregate) to the outside.
The primary component of lime plasters is lime putty
, a hydrated-lime product (calcium hydroxide,) with the consistency of sour cream.
