The Traditional Building Character (TBC) Overlay is integrated into the zoning regulations of Brisbane's City Plan. Specific areas and neighbourhoods that are characterised by pre-war housing are designated as having this overlay, and any development or renovation within these areas is subject to the regulations and may require a development application.

The Purpose of the Traditional Building Character Overlay.

• The primary purpose is to conserve and protect Brisbane's historical heritage by safeguarding the distinctive features of pre-1947 homes.

• The TBC Overlay aims to maintain the cohesive and harmonious character of neighbourhoods containing traditional houses, contributing to the overall identity of these areas.

• Focuses on preserving the architectural significance of pre-war houses, including key design elements, building materials, and streetscape aesthetics.

It's essential for property owners and developers to familiarise themselves with the specific guidelines outlined in the Traditional Building Character Overlay for your site and consult with town planners and architects during the planning stages to ensure compliance with these regulations. Keep in mind that regulations and overlays may be subject to updates, so it's advisable to check with the official Brisbane City Council online planning scheme for the latest information.

What are Brisbane town planners looking for?

When renovating a house within the Traditional Building Character (TBC) Overlay in Brisbane, homeowners need to adhere to specific guidelines and considerations set by the Brisbane City Council. Specifically you the Council town planners will assess your project against the Traditional Building Character Design Overlay Code.

Here are key aspects that the Council typically looks for when evaluating renovation proposals within the TBC Overlay:

1. Respect for Traditional Features:

• Retaining Original Features: Preservation of original architectural features, such as decorative elements, windows, doors, verandahs, and roof forms, is highly encouraged. The aim is to maintain the unique character of pre-1947 houses.

• Revealing or Reinstating Features: In some cases, revealing or reinstating original details that may have been altered or covered over the years is seen favourably.

2. Sympathetic Extensions:

• Design Harmony: Any extensions or alterations should be sympathetic to the existing traditional house. This involves ensuring that the new elements seamlessly integrate with the original design and contribute positively to the overall streetscape.

• Transition Zones: Incorporating transition zones between new and old sections helps create a harmonious blend and minimises the visual impact of the extension.

3. Roof Design:

• Harmonious Roof Lines: Ensure that the roof design of the extension harmonises with the existing rooflines of the pre-war home. Aim for a seamless transition rather than stark contrasts in roof styles.

• Consideration for Pitch and Materials: Match the pitch of the new roof to that of the original dwelling. Consistency in roofing materials, whether it's tiles, shingles, or other traditional materials, contributes to visual unity.

4. Scale and Proportion:

• Size and Scale Considerations: The size and scale of any new construction should be in proportion to the original dwelling and neighbouring properties. Avoiding oversized or dominant extensions is crucial to preserving the visual balance.

• Setback Compliance: Adhering to setback regulations, both in terms of front and side setbacks, is essential. This ensures that the streetscape and neighbouring properties are not adversely affected.

5. Material and Design Consistency:

• Material Choices: Using materials that are consistent with the era of the original house is encouraged. This helps maintain the traditional aesthetic and contributes to the overall heritage character.

Design issues to be considerate of.

When designing a new house or renovating an existing one in the Traditional Building Character (TBC) Overlay in Brisbane, homeowners should be mindful of certain considerations to ensure compliance with the overlay guidelines and respect for the local character. Here are some things to avoid:

1. Overlooking Heritage Features:

• Avoid Removing Original Features at the front of the house: Resist the temptation to remove or replace original heritage features, such as decorative elements, windows, or verandah details. Preservation of these features contributes to the historical character of the property.

• Don't Neglect Restoration Opportunities: Avoid neglecting opportunities to restore or reveal original details that may have been concealed or altered over the years.

2. Incompatibility in Design:

• Avoid Clashing Architectural Styles: When designing new elements or extensions, avoid architectural styles that clash with the traditional character of the house or the surrounding neighbourhood.

• Discourage Incongruent Additions: Refrain from incorporating additions that are visually incongruent or overly dominant compared to the original structure. This can disrupt the cohesive streetscape.

3. Ignoring Setback Regulations:

• Avoid Inadequate Setbacks: Neglecting setback regulations can impact the overall streetscape and may result in a lack of visual harmony. Ensure compliance with front and side setback requirements.

• Minimise Overshadowing: Avoid designs that lead to excessive overshadowing of neighboring properties, especially when constructing multi-story extensions.

4. Mismatched Materials and Colors:

• Inconsistent Material Choices: Avoid using materials that are inconsistent with the era of the original house. Mismatched materials can detract from the overall heritage aesthetic.
