The hotel classification is a business hotel. This type of hotel prioritizes business visitors and event organizers who will hold seminars, performances and so on, but the regular hotel guests who want to travel around are welcome too. The main target of the hotel is the businessman, so the support facilities in the bedroom focused on the working area for visitors, while the room still focusing primarily on the comfort of sleep and entertainment for visitors such as television, outside scenery, and good bathroom. Convention hall can be incorporated into one building with the hotel or apart. The main advantage when the convention hall is in different buildings with the hotel is the circulation of visitors who want to stay in the hotel, and the convention hall users can be separate so that the circulation won't be very traffic. The main disadvantage when the convention hall separate from the hotel is the narrowed land [3].
Hotel and convention hall is divided into two resident, namely visitors and managers. Visitors are divided into two: regular visitors (stay in the hotel) or temporary visitors (using the convention hall only or other supporting facilities). The hotel manager is divided into two, frontof-house and back-of-house managers. Front of the house manages direct services to visitors, such as receptionists, security, cleanliness, room service, and concierge. Back of the house manages the services that serve visitors indirectly, such as kitchen, food and beverage managers, utility operations (bathroom, air handling unit, warehouse management, and financial administration management).
Spatial needs are divided into two main areas those are visitor area and management area. The visitor area is divided into four areas: convention hall area, recreation area, reception area and hotel room area. The management area is divided into two main areas: front of the house and back of the house. Front of the house area is divided into eight areas; they are the guest room, public area, lobby area, reception area, guest elevator area, concierge area, convention hall area and parking area. Back of the house is divided into three areas, they are kitchen area, office area manager, service area [1].

The convention hall has a grand ballroom that can separate into two junior convention hall to accommodate little seminar. The shape of the building is completed with site form analysis; there is Selayang River which divides the design site so that the river is set to be the limitation, so the parking area is focused on the small section of the river. For the vegetation, Hotel and Convention Hall Selayang use palm trees to increase the ambiance of tropical climate and for the visual. Some of the land in the site is functioning as a drain for rainwater and for the visual it design to be a tropical garden.

The application of Neo Vernacular in the building is taken from Malay Architecture, with the uniqueness of columns, windows, doors, and roof. Malay architecture is applied with modern technology in the form of steel reinforcement on columns and beams, and on the door and window using aluminum and wood [2]. A typical Malay roof is applied to a wide span of convention hall using a truss system. The utility and services are on the basement floor of the hotel. The access is from behind the site near the hotel exit. The employee that works in the hotel uses that path to reach the building.

Landscape
The shape of the landscape is like a trapezium with an arc in three sides. The shape of the site is based on the master plan design. There is a focal point which is a garden in the center of the master plan (Figure 3). First of all, the site shape is analyzed with the direction and the suppression of the site. There is a major axis that direct to the master plan focal point. There are two lines that cut the site shape into three area; they are Selayang River and sky-bridge.

Figure 3. Site Shape Concept
Vehicle circulation in the site divided into two, convention circulation and hotel circulation ( Figure 4). The circulation is separate to avoid the traffic inside or outside the site. The entrance of the hotel is using the side street. Hotel circulation has to be simple because not many cars will park, they will often use the drop-off or the entrance hall area. The entrance of the convention hall is on the main street of the master plan. The convention circulation has a direct through a pass, so if the vehicle just wants to drop off or pick up, they can easily exit from the site. The parking lot in the convention is larger than the parking lot in the hotel to accommodate the customers in the convention hall.

Building Mass and Form
The building mass and form are according to the site form. The suppression and the axis direct the direction of the building. The main façade is directed to the main street in the master plan.
The structure of this mass is rigid frame because it is not too complicated and build from piles and beams ( Figure 6). Convention hall use space truss structure system, to handle a large amount of space in the grand ballroom.   The façade uses a vernacular architecture approach referred to Malay architecture. The building uses the modern structure, but the image of the building is traditional (Figure 9). The building is for commercial and needs to attractive, so the design is a luxury and still calm. The building of the hotel and the convention hall space is separated because with a large enough land can be utilized for more space for costumers, the open space available is also wide enough for parking and garden as water absorption because the location is crossed by Sungai Selayang, and around the location mostly is the settlement. Parking space provided is wide enough to anticipate congestion outside the area because it will disturb residents around. The land is also integrated with a master plan that containing commercial buildings such as art museums, youth
