Townhouses are generally 2 to 4 storey structures that share a sidewall with a neighbouring unit and have at least three housing bays. They typically have a front and a back view.
These guidelines relate to existing townhouse layouts and seek to facilitate consistency in the processing of applications for the structural alterations and addition to existing townhouses. The guidelines would assist in maintaining and enhancing the general quality of townhouse design and layout within communities and neighbourhoods, and ensure the following for all residents:
- Enjoyment of property.
- Safeguarding of public safety and enhancing of public health.
- Access to adequate natural light and ventilation.
- Enjoyment of significant views.
- Adequate privacy.
- Adequate land space to facilitate proper circulation of vehicles, car parking spaces, and landscaping on the site.
- Preservation of quality streetscapes.
“All plans and drawings must get stamped approval of the Housing Development Corporation (HDC) in the case of state developments.”

Size and Density
- Proposals for addition and/or alterations must not exceed the permitted building setbacks applicable to the existing development.

- Proposed additions and alterations must ensure adequate privacy to all occupants of the townhouse units.
- There should be mutual agreement between residents for the preferred design, aesthetics, and features for additions to relevant blocks of townhouse units.
