design diversity (one of LEED’s requirement for sustainability) and height diversity as well (Figure 7a).
Land use has been improved and a number of facilities were increased by converting some units into
services for the daily important and missing facilities, such as adding supermarket, laundry, pharmacy
to be within 300m ‐ 500m for more than 50% of the community units to fulfill the LEED’s land use
diversity requirement (Figure 7b).

4.2. Scenario Two
The second opportunity is enhancing the community services as well as the accessibility by
opening new access to the neighbor community, Layan community, as both of these communities are
developed by the same developer (DPG). The new access will allow the residents to benefit from some
services that are already existed in Layan community such as supermarket, bookshop, and small cafe.
Furthermore, opening new access to Al Quadra Road will enhance the accessibility and the movement
entirely (Figure 8).

enhancing access [6].
Opening new access to Layan community (Scenario Two) would improve the community livability,
even though some services are still indicating a weak performance such as educational and medical
services. This could be resolved by providing these services (primary school or medical center) in Layan
community as it is larger in area and has a number (7) of mid‐rise buildings, which could be useful for
this type of services (Table 1). Both scenarios 1 and 2 indicated improvement toward a more sustainable
setting as most of the mentioned services are within the LEED ND requirements (i.e. 200m ‐ 300m)
