1 Session One: The Concept of Conservation Looking after a place so as to retain its meaning. Main Approaches

2 Preservation protect, maintain, stabilize

3 Rehabilitation repair, alterations, additions

4 Restoration revealing, recovering or representing the building at a particular time Abbott House, 1899 1970s today

5 Being restored

6 Advice from around the world

7 Diderot 1713 - 1784 It is better to preserve than to repair, better to repair than to restore, better to restore than reconstruct.

8 William Morris 1834 - 1896 Stave off decay with daily care.

9 Sir Bernard Fielden 1919 - 2009 Regular maintenance please!!

10 The Burra Charter 1979 Do as much work as is necessary, but as little as possible.

11 Canada ’ s Standards and Guidelines 2003 Minimal Intervention

12 How to understand heritage values Statements of significance Archival research Talk to neighbours Explore the neighbourhood

13 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

14 Examples of the Standards & Guidelines being applied or not

15 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.

16 The Lea Residence 3997 West Broadway

17 Moving buildings 1893, Library and Archives Canada/PA-126388

18 Since 1930..

19 Watson House 1985 1987

20 Current location on Pendrell Street

21 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

22 Stanley Theatre 1940s today

23 1500 Block Commercial Drive 3. Conserve heritage value by adopting an approach calling for minimal intervention.

24 Mole Hill

27 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

28 Pacific Heights Co-op 1985 today

29 The New Vancouver Special before after

30 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

31 Schara Tzdeck 1917 – synagogue 1948 – Gibbs Boys Club 1980s – condominiums

32 Schara Tzdeck

33 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

34 Archaeological sites Fraser Arms Hotel, Vancouver

35 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

36 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

37 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

38 Session 2: Reading the building exterior Understanding what needs conserving, and why

39 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

40 Reading a building Part 1: Cataloguing the exterior materials and their condition: foundations walls porches windows and doors roofs, gutters, downspouts, flashings masonry

41 foundations walls porches

42 windows and doors roofs, gutters, downspouts, flashings masonry

43 Reading a building Part 2: Understanding traditional exterior assemblies...

44 ... and contemporary requirements for exterior assemblies

45 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:

46 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

47 Session 3: Case Study Mission to Seafarers Understanding what needs conserving, how, and why

48 Components of a Statement of Significance 1.Description of Historic Place 2.Heritage Value 3.Character Defining Elements

49 Description – Key Points 1 ½ storeys, semi-prefabricated, location

50 Heritage Values aesthetic – Craftsman-influenced semi-prefabricated

51 Heritage Values associative – early lumbering activity (BC Mills), Harbour Commissioners, National Harbours Board, Mission to Seafarers

52 Heritage Values Social – use as a Mission established by the Anglican Church

54 Character Defining Elements design – e.g. pre-fab,verandah, hipped roof, brick chimney

55 Character Defining Elements relating to evolving use Vault at rear Wrought iron railing

56 Character Defining Elements relating to social value - BLUE

57 Use a form to catalogue your material observations

58 Session 4: Developing a Conservation Plan for the Mission to Seafarers Strategies for the exteriors that conserve heritage value

59 Heritage Branch of BC Conservation Plan Flow Chart

60 Use the Standards and Guidelines

61 Session 5: Case Study Buildings along Heatley Avenue Understanding what needs conserving, and why
