9.3.1.1 Contemporary Alteration Approach

keep introduction

Guidelines:

Principles

• Alterations and additions using this approach should respect, and be consistent with, the original design of the building.
• Many contemporary buildings are old enough to have already undergone renovations, which may not be in character with either the original design or historic precedents in the area. In such cases, the design of further alterations should restore the architectural consistency of the whole.

Additions

• The general guidelines in Section 9.2.5 for additions to heritage buildings applies to additions to non-heritage buildings in terms of location, scale and building form.

Windows

• The use of wood windows in a renovation of an existing building or new wood windows in an addition is encouraged.
• The use of windows in a renovation of an existing building or new windows for an addition in other materials such as vinyl or aluminium is also acceptable.
• Notwithstanding the material of the window, the shape, configuration and profile of the new window should complement or reflect the architectural design of the building. For example, a single hung sash window with 2/2 pane division on a Class B building should be replaced with a similar style of window as opposed to a single pane casement window.

Roof Materials

• The use of asphalt shingles in a colour that complements the architecture of the building is acceptable. Traditional shingle colours such as greys, blacks and browns are encouraged as these are commonly used in the District.
• The use of wood shingle roofs is acceptable.
• Not all new roofing material is necessarily appropriate for use in a Heritage District. The use of the following roofing material is not supported: sheet metal roofs, clay tile roofs, and plastics and other synthetics.

Wall Materials

• The retention or use of traditional materials and products such as clay brick and wood sidings are encouraged.
• The use of non-traditional or modern materials such as cement fibre board, vinyl and aluminium in configurations and profiles that complement the original design of the building is also acceptable. For example, the 5” horizontal wooden siding on a Class B building could be replaced with a 5” horizontal vinyl siding.
• Not all exterior wall materials are necessarily appropriate for use in a Heritage District because they are not typical of the local vernacular architecture. The use of the following material is not supported: stone or artificial stone, concrete block and concrete brick, precast or poured concrete, terra cotta, and glazed tile.

Decorative Features

• The introduction of new architectural or decorative features should be in keeping with the architectural style and period of the building.

Soffits and Fascia

• Materials that can be used include wood, cement fibre board, aluminium and vinyl.

Colours

• The use of paint colours complementary to the character of the contemporary style of architecture or from a heritage palette (available from most paint companies) is considered appropriate.

Approval

• Generally, all exterior alterations to buildings in a designated Heritage District require a permit issued by the municipality. See Section 8.3 for details.
• Alterations to existing non-heritage buildings that are compliant with the policies and guidelines can be reviewed and approved by Heritage Section staff without having to be reviewed by Heritage Markham or Council.

9.3.1.2 Historical Conversion Approach

keep introduction

Principles

• Exact replication of the design of existing heritage buildings within the District is not supported.
• Avoid the introduction of a singular piece of historical decoration on a non-heritage building (i.e. a section of “gingerbread” trim)

Additions

• The general guidelines in Section 9.2.5 for additions to heritage buildings applies to additions to non-heritage buildings in terms of location, scale and building form.
• Although most additions should be modest in comparison to the original building, the Historical Conversion approach may result in substantial additions in front of and/or on top of the existing building.

Windows

• The use of wood windows in a renovation of an existing building or new wood windows in an addition is encouraged.
• The use of windows in a renovation of an existing building or new windows for an addition in other materials such as vinyl or aluminium is also acceptable.
• Notwithstanding the material of the window, the shape, configuration and profile of the new window should complement or reflect the proposed historical architectural style of the building.

Roof Materials

• The use of wood shingle roofs is encouraged.
• The use of asphalt shingles in a colour that complements the proposed architecture of the building is acceptable. Traditional shingle colours such as greys, blacks and browns are encouraged as these are commonly used in the District.
• Not all new roofing material is necessarily appropriate for use in a Heritage District especially in the Historical Conversion Approach, because they are not typical of the local vernacular architecture. The use of the following roofing material is not supported: sheet metal roofs, clay tile roofs, and plastics and other synthetics.

Wall Materials

• The use of traditional materials and products such as brick and wood sidings are encouraged.
• The use of non-traditional or modern materials such as cement fibre board, vinyl and aluminium in configurations and profiles that complement the proposed design of the building is also acceptable.
• Not all exterior wall materials are necessarily appropriate for use in a Heritage District. The use of the following is not supported: insul brick, stone or artificial stone, concrete block and concrete brick, precast or poured concrete, terra cotta, and glazed tile.

Decorative Features

• The introduction of new architectural or decorative features should be appropriate to the desired architectural style and period of the building.
• Avoid the use of decorative features not typical of the local vernacular.

Soffits and Fascia

• Materials that can be used include wood, cement fibre board, aluminium and vinyl.

Colours

• The use of paint colours complementary to the proposed style of architecture or from a heritage palette (available from most paint companies) is considered appropriate.

Approval

• Generally, all exterior alterations to buildings in a designated Heritage District require a permit issued by the municipality. See Section 8.3 for details.
• Alterations to existing non-heritage buildings that are compliant with the policies and guidelines can be reviewed and approved by Heritage Section staff without having to be reviewed by Heritage Markham or Council.
