Restoration

Surveys

When purchasing a listed building, it is important to understand it’s structural condition.

Historic building surveys of listed buildings need a higher level of expertise and precision to that of a standard building survey.

Our experience in the conservation of period and listed buildings, and the experience of our structural advisors means we can offer a range of services from architectural and structural building surveys, to advice on alterations needing listed building planning consent.

We are able to offer complete restoration packages for oak infill panels, using the latest methods and materials. We are able to repair and/or replace existing deteriorated oak frames.

 

Planning

Listed buildings require consent before any alterations and extensions, potentially affecting the appearance and character of the building, can occur.

A building is classed as “listed” when it has been recognised by the Secretary of State for Culture, Media and Sport (a government department) as of architectural and/or historical interest. There are three “grades” of listing.

Grade 1 buildings are assigned a status of “exceptional interest”.

Grade 2 buildings are defined as being “particularly important buildings of more than special interest”.

It is a criminal offence to carry out any works on a listed building without authorisation. Our expert team are able to assist you with any queries you have over planning, or alternatively take care of the process for you.

Lime Conservation and Restoration

Richoak not only restore oak frames of period and listed buildings, we also restore and conserve lime plastering and rendering.

Lime has been traditionally used in the protection and decoration of buildings for thousands of years. Lime mortar is a type of mortar consisting of lime, water and an aggregate (sand). Lime mortar is a soft, porous substance ideal for use when working with softer construction materials, such as timber and natural stone.

Lime has many advantages over modern day cement. Lime mortar is considerably more “breathable”, wicking any dampness in the wall to the surface where it evaporates, leaving salt crystals from the water on the lime. This, therefore damages the lime, preserving the timber frame or masonry of the building itself. Whereas, with cement, the salt content from the water crystallises on the brick surfaces, as they are more porous than the cement. This causes the bricks to disintegrate, damaging the structural conformation of the building.

Lime is a much more resilient mortar than cement. Under cracking conditions, often caused by the movement and shrinkage of an oak frame over time, lime creates various micro cracks. These micro cracks re-crystallise, effectively healing the affected area. Under similar circumstances, cement breaks and cracks, resulting in higher reparation and maintenance costs.

We’ll oversee your renovation project from start to finish, from the surveying and planning processes, through to the overall competition of your building.
