Conservation and Restoration Flashcards
What is a listed building?
It refers to a building which is included on the list of ‘buildings of special architectural or historic interest’. Recognises that a building is special in a national context and brings with it controls over alteration, extension and demolition. Grades 1, 2, 2* listings.
What is the difference between conservation and restoration?
- Conservation - maximum amount of the original material is kept in as unaltered a condition as possible. All repairs/additions must be reversible without affecting original.
- Restoration - returning building to former state. Accurately recreate its form, features & character as it appeared whilst its protecting its heritage.
How would you go about identifying an age of a building?
- Visual inspection of features that can give clue to period ie bay windows 1930’s.
- Original meters still installed with dates
- Solid or cavity walls (brickwork pattern)
How does listing of a building affect the Building Regulations requirements?
Listed buildings exempt from Part L if works would alter character of their significance. Part B - no worse than existing
How do you treat dry rot?
1 remove/remediate moisture source
2 Replacement of defective timber
3 Chemical treatment to adjacent areas
How do you treat wet rot?
1 Identify cause/source
2 remove affected timber
3 treat nearby areas
How do you ensure Part L requirements are being met whilst protecting the historic features of a building?
I would liaise with builder and historic england to determine what areas form part of the significant interest in the building and whether the walls etc can be thermally upgraded.
Mile End - How did you know it was dry rot and not wet rot
Timber was dry and brittle, no obvious point of leaking, rot has spread along lengths of beam
Mile End - What other remedial options were there?
To cut timber out was only remedial, but jointing of timber could have been different ie joists hangers etc
