Q&As Refurbishment of Listed Buildings

What makes a building listed?

A building is listed when it is of special architectural or historic interest in a national context. Listed buildings have extra legal protection within the planning system.

Listed buildings come in many styles and sizes and range from terraced houses to simple country cottages and stately homes.

There are three categories of listed buildings, based on their significance:

Grade I buildings are of exceptional interest and only, 2.5% of listed buildings are Grade I

Grade II* buildings are particularly important buildings of more than special interest and just 5.5%of listed buildings are Grade II*

Grade II buildings are of special interest and the vast majority, 92%, of all listed buildings, fall into this category. There are around 500,000 listed buildings in England, but it is difficult to be precise, because one listing, for example, can cover a clock tower and another a row of shops

How are buildings chosen for listing?

Not surprisingly, the older a building is, the more likely it is to be listed. All buildings built before 1700 which survive in anything like their original condition are listed, as are most of those built between 1700 and 1840

The more modern a building is, the more remarkable it will need to be if it is to be listed. Buildings that date from 1945 onwards need to be particularly carefully selected and usually, a building must be over 30 years old to be eligible for listing

To help people to understand the selection process English Heritage publish selection guides for many different types of buildings that clearly set out how Historic England recommends a building for listing or not

How to find out about your listed building

A listed building is included on a statutory list – The National Heritage List for England which you can access through a portal to find out why the building has been listed, what aspects are to be preserved and what the status of the listed Grade

Listing started after World War II, earlier listings were for identification purposes only. The more recent the listing the more information should be available

Are there any benefits of trading from a listed building?

Listing is a mark of special interest in a national context and most owners/occupiers are rightly proud of their special building. Inclusion on the National Heritage List for England means that the building makes a contribution to the specialness of England’s diverse historic environment. It can also increase the value of the property.

What parts of the building does a listing apply to?

A Listing covers the whole of the structure including the interior unless sections are explicitly excluded in the listing entry and will cover any part or structure fixed the fabric of the building and any object or structure within the building envelope which, though not fixed to the building forms part of the land

All listed buildings are different and what is actually covered can vary, it is prudent to check with your local planning authority or your Listed Building consultant or Contractor

How to go about obtaining Listed Building Consent?

You should contact your local planning authority to apply for listed building consent or alternatively use a Listed Building Planning Consultant or a Contractor conversant with working on listed buildings to help. Local authorities have a statutory period to decide within 8 weeks though due to stretched resources in most local authorities this can be longer. Select Interiors have extensive experience working on Listed Buildings see link for a small selection of projects. We offer a full design and fit out service which we submit drawings and work in conjunction with trusted and cost effective Listed Building Consultants as a full package saving the headache of dealing with multiple agencies

What would happen if I refurbish a listed building without applying for listed building Consent?

Undertaking unauthorised works to a listed building is a criminal offence and you can be prosecuted. The planning authority can issue an enforcement notice and insist that all works carried out are reversed. You should always consult the authority, your consultant or contractor before any works are carried out. Usually your tenant’s fit out guide / Landlord’s surveyors will require a copy of your application approval for alterations as part of your lease agreement

What differences in the construction of older buildings compared to modern methods?

Most listed buildings dating pre- World War I were built with either solid masonry or with a timber frame and infill panelling. These types of construction differ from modern buildings in that permeable materials were used which allow moisture – rain, groundwater and internal moisture to evaporate. The introduction of modern heating upsets the equilibrium and creates moisture through condensation. Also, no damp courses, cavities, insulation and vapour barriers mean that older buildings can hold more moisture

How can we treat walls and floors for damp?

Simply introducing, for example, insulation & vapour barriers introduced for example within a replacement floor slab can result in moisture being driven into adjacent walls/construction. Similarly injecting modern chemical damp course products into solid walls to solve the damp will be detrimental rather than solving penetrating or rising damp. Surface treatments to seal masonry will also be ineffective and will tend to trap moisture in rather than sealing moisture out

Grade II listed buildings case studies

To illustrate our approach to the above question here are 3 case studies which show how Select Interiors approached Grade II listing

Timber and masonry treatments

1. Old Parsonage in Didsbury

How we worked with Manchester City Council, The National Lottery Fund and Didsbury Heritage Trust to sympathetically refurbish and treat damp within the Grade II Listed Old Parsonage in Didsbury

The above process included hacking off damp plaster to 1000mm high throughout ground floor which includes:

  • Isolation and removal of period radiators
  • Removing and replacing dry & wet rot infected timbers & joists
  • Thorough cleaning of exposed masonry, treating with salt retarder and installing a tanking membrane through to void joists
  • Additional air bricks were installed to further ventilate the floor void to help any penetrating / rising damp evaporate naturally
  • The render was replaced with traditional Lime based mortar and skim finish

Removal of the original plaster which was retaining moisture due to ingress and activated hygroscopic salts in conjunction with the membrane which incorporated air pillows within the structure solved the damp problems. We also excavated a French type drain to the front & rear elevations filled with limestone crush to help wick away the rising damp. The combined treatments were modern interventions that solved the damp issues without compromising the period features. See images of the completed project below.
