Advisory Notes
The guidelines set out in this handbook for the various development control parameters will generally be applied by URA in the consideration of a development application. However, if the circumstances of a case or the planning considerations relevant to a case so warrant, URA may in its discretion decide to depart from these general guidelines. Persons intending to carry out a development are advised to take this into consideration in the conduct of their affairs and check with URA through enquiries or development applications to confirm if their proposals can be allowed.
The guidelines, principles and illustrations found in the handbook series are not exhaustive in covering all possible site conditions and building designs. In evaluating the development applications, URA reserves the right to evaluate and impose conditions not covered in the handbook in respond to the specific design of the development proposal depending on merits.
Introduction
Illustration of a Semi-Detached House
A semi-detached house is one half of a pair of two houses, each with its own land title, separated by a common party wall along one side of the premises. The pair of semi-detached houses is attached either side-to-side or back-to-back as illustrated above.
If an adjoining semi-detached house is demolished or redeveloped into a different housing form (e.g. to a bungalow), the left-behind (or existing) semi-detached house shall remain a semi-detached house as originally approved.
Semi-detached houses may be built in either areas designated for semi-detached housing or mixed landed housing, if the development site area can meet the requisite minimum plot size and plot width.
A semi-detached house shall adhere to the applicable storey height, envelope control guidelines and building setback requirements under the envelope control guidelines. The permissible Gross Floor Area (GFA) for landed housing is resultant of the allowable building height and envelope.
