1. Strata landed housing is a form of landed housing that comes with strata titles. They are allowed within landed housing estates, including Good Class Bungalow Areas (GCBAs), and offer home buyers a housing option that combines landed housing living with communal facilities and greenery like those available in private condominiums. 
2. To better safeguard the pleasant living environment in landed housing estates, URA has revised the existing guidelines for strata landed housing developments.

Maximum Number of Allowable Dwelling Units

3. Under the revised guidelines, the following formulae will determine the maximum number of dwelling units (DUs) allowed in the various types of strata landed housing developments:
   
   

   Type of strata landed housing developments	Formula to calculate maximum number of DUs allowed1
   Outside GCBAs	40% of site area Y Where Y = Typical footprint for the relevant conventional landed housing form2
   Within GCBAs	35% of site area Y  Where Y = Typical footprint for a Good Class Bungalow2
   Mixed strata landed housing developments comprising more than one housing form (e.g. a mix of terrace, semi-detached and detached housing units) outside GCBAs	(B x Y) + (SD x Y) + (T x Y) ≤ 40% of site area Where B = number of detached housing units SD = number of semi-detached housing units T = number of terrace housing units Y = Typical footprint for the relevant conventional landed housing form2

4. The new formulae will improve the compatibility of strata landed housing developments with the environment of landed housing estates. It also addresses feedback from residents in landed housing estates that strata landed housing developments could inject a disproportionately large number of DUs, causing additional traffic and parking problems along the local estate roads and creating a more congested living environment.

Communal Open Space (COS) Requirement with Minimum On-Ground Greenery Control

5. To safeguard more space for communal facilities and greenery within strata landed housing developments, we will raise the minimum Communal Open Space (COS) requirement from 30% to 45%. Of the 45%, at least 25% must be set aside for on-ground greenery. This will enhance the living environment within strata landed housing developments, as well as the landed housing estate as a whole. This also complements URA’s push for more greenery in our urban environment through the LUSH 2.0 Programme announced on 12 June 2014.
   
    

Implementation

6. The revised guidelines will apply with immediate effect to all new applications submitted on or after 23 August 2014. Only formal development applications (excluding Outline Applications) submitted before the effective date of 23 August 2014 which have already been granted Provisional Permission or which will result in a Provisional Permission, will not be subject to the revised guidelines³.
7. Notwithstanding the revised guidelines, should a strata landed housing development be proposed in an area with localised problems (e.g. severe infrastructure capacity issues), URA may impose tighter requirements including restricting the DUs further in consultation with other agencies.

¹ The number of units will be rounded down to the nearest round figure.
² The typical footprint of the various conventional landed housing forms is 100sqm for terrace and semi-detached housing, 200sqm for detached housing, and 500sqm for Good Class Bungalows.
³ Development applications for strata landed housing submitted before the effective date of 23 August 2014 resulting in an Advice or Refusal of Written Permission (RWP) will be evaluated based on the revised guidelines upon resubmission after the Advice or RWP.
