This is a big question quite often needing a whole course on conservation, restoration and so on. English Heritage have a wealth of information. SPAB is a good source, the Society for the Protection of Ancient Buildings. I have an old book called Investigating Old Buildings by Lance Smith that shows how to survey old buildings. Good luck.

Good evening

Mr Gover has provided some valuable resources such as English Heritage and SPAB in UK. Other UK based resources that you may find informative are: The Historic Environment Scotland (https://www.historicenvironment.scot/), The Institute of Historic Building Conservation - IHBC (http://www.ihbc.org.uk/), The Council on Training in Architectural Conservation - COTAC (https://www.cotac.global/), The Construction History Society - CHS (http://www.constructionhistory.co.uk/), to name a few.

Alternatively, you may want to look into the The International Centre for the Study of the Preservation and Restoration of Cultural Property - ICCROM (https://www.iccrom.org/) which is based in Italy.

I hope this helps.

@Vladimir Ladinski Thank you so much

Also, adding to Vladimir Ladinski's excellent list:

could be worth trying. I am a member of the CIOB. They have favourable rates for students and possibly could supply some information free. It might be worth asking via

Good luck,
