Height is capped twice over: by the regime the plot falls under, and by the width of the road that reaches it. The lower of the two governs.
Where a plot abuts two or more streets of different widths, the plot is deemed to abut the wider street for the purpose of the height rule, and that height may be carried along the narrower street as well.
KMBR 2019, Rule 24(1)(b) — and 1 related rules below.
Where a plot abuts two or more streets of different widths, the plot is deemed to abut the wider street for the purpose of the height rule, and that height may be carried along the narrower street as well.
The maximum height of a building or part of it shall not exceed twice the width of the abutting street plus twice the width of the yard between the building and that street. Three qualifications were added in October 2025. First, the rule does not apply at all to single or dual unit residential buildings of not more than 8.0 m — an ordinary house is now out of the street-width regime entirely. Second, where the building has a podium, the yard value taken is the one corresponding to the top level of the podium. Third, the restriction is compulsory only for a building or part of a building falling within 9 m of the building line, so a tower set well back is not limited by the street it faces.
