Conservation Plans GOAL - to conserve heritage values and extend the physical life COMPONENTS - identify values and Character Defining Elements INTERVENTION – what level? (preservation, rehabilitation, restoration) APPLY – Standards & Guidelines
Examples of the Standards & Guidelines being applied or not
1. Conserve the heritage value of a historic place. Do not remove, replace, or substantially alter its intact or repairable character- defining elements. Do not move a part of a historic place if its current location is a character-defining element.
The Lea Residence 3997 West Broadway
Moving buildings 1893, Library and Archives Canada/PA
Since
Watson House
Current location on Pendrell Street
2. Conserve changes to a historic place which, over time, have become character-defining elements in their own right. Hawks Avenue in Strathcona (1905 & 1924) Circa 1945
Stanley Theatre 1940s today
1500 Block Commercial Drive 3. Conserve heritage value by adopting an approach calling for minimal intervention.
Mole Hill
4 Recognize each historic place as physical record of its time, place and use. Do not create a false sense of historical development by adding elements from other historic places or other properties or by combining features of the same property that never coexisted. Point Grey, Vancouver
Pacific Heights Co-op 1985 today
The New Vancouver Special before after
5. Find a use for a historic place that requires minimal or no change to its character-defining elements. Brock House 1913 Glen Brae / Canuck Place 1910
Schara Tzdeck 1917 – synagogue 1948 – Gibbs Boys Club 1980s – condominiums
Schara Tzdeck
6. Protect and, if necessary, stabilize a historic place until any subsequent intervention is undertaken. Protect and preserve archaeological resources in place. Where there is potential for disturbance of archaeological resources, take mitigation measures to limit damage and loss of information. Ceperley Bldg & BC Yukon Chamber of MinesTerminus Hotel
Archaeological sites Fraser Arms Hotel, Vancouver
7. Evaluate the existing condition of character-defining elements to determine the appropriate intervention needed. Use the gentlest means possible for any intervention. Respect heritage value when undertaking an intervention. BeforeAfter cleaning
8. Maintain character-defining elements on an on-going basis. Repair character-defining elements by reinforcing their materials using recognized conservation methods. Replace in kind any extensively deteriorated or missing parts of character-defining elements, where there are surviving prototypes. Princess Avenue, Strathcona
9. Make any intervention needed to preserve character-defining elements physically and visually compatible with the historic place, and identifiable upon close inspection. Document any intervention for future reference. Barclay Manor, West End
Session 2: Reading the building exterior Understanding what needs conserving, and why
Using a common building vocabulary Window sash (frame not easily seen) trim Downspout (or rainwater leader) Decorative pediment woodwork: sunburst pattern Bargeboard tail Bargeboard w/moulding Decorative shingling Trim board w/moulding bargeboard Fascia under gutter Drop siding Tongue & groove paneling Moulding & trim boards Lap siding Water table or trim board Bevel siding: 4” exposure soffit Corner trim board
Reading a building Part 1: Cataloguing the exterior materials and their condition: foundations walls porches windows and doors roofs, gutters, downspouts, flashings masonry
foundations walls porches
windows and doors roofs, gutters, downspouts, flashings masonry
Reading a building Part 2: Understanding traditional exterior assemblies...
... and contemporary requirements for exterior assemblies
what looks original/what looks like its built later? develop a story of the importance of the place compile a list of elements critical to showing the important parts of its evolution Reading a building Part 3: Piecing together the evolution of the building, and its values:
Putting it together Is the foundation for conservation plan Knowing the building parts and their condition Having a fair idea of the assemblies Having a likely scenario of the evolution of the building and values
Session 3: Case Study Mission to Seafarers Understanding what needs conserving, how, and why
