RAW architecture’s latest project is the ‘rivoli hotel‘ located in a crowded area next to the kramat raya street in east jakarta. the building stands within a 1500 sqm plot, with only 16 m width facing south and 97 m length facing west. during the early construction phase, this area already had existing main columns on a one-floor-high construction. the plan has been a business hotel with a program yet to be discussed in detail.
indonesian based firm RAW architecture‘s hotel has been planned to inject a new design by splitting building masses from the north-south side. the splitting achieved by few lightwell corridors — placed in linear manner — allows light to penetrate from a transparent roof to the first floor. each 1 m x 4.5 m lightwell is installed on the highest point of the building’s 4th floor, creating a luminous bridge before entering the rooms on the west side.
RAW has designed the west and east side of the hotel to be more introvert. this is achieved by a plane that weaves from an imaginary line of view, forming a rationalized balcony with a 2.5 m concrete cantilever width and 6 m diagonally. this cantilever functions as the room’s eaves and gives shade to the west side from 3 pm at noon until night time. this concrete cantilever also focuses the vista and landscape from the south side area, which is the kramat raya street to tugu tani street and the capital city’s landmark monas. this cantilever’s projection also forms a passive design inside the planned interior of the hotel.
this hotel is designed with a 21 m2 module per room. each one is composed by a bathroom (20%) and two bedrooms (80%). the design totaled of 109 rooms on a 4-7-4 m grid section long and 7.7 m width, includes a briefing area placed on the first floor of the building. the basement area is designed to receive natural light and air by a cross ventilation system. the hotel corridors are also designed to gain the same effect from the north and south side areas.
the material design has been chosen focusing on an easy maintenance and accessibility towards minimal cost due to the financial situation available within the construction period. this followed by a 15-month-period time challenge, which RAW architecture’s solution is to design the building’s structure with a prefabricated floor plate technology to accelerate construction time.
