Project #1 Residence of Riduwan Ibrahim Jakarta - Indonesia

The Mansion is owned by an Indonesian couple with Arabic and Indian decendants.

The couple’s dream house is to have a ‘shelter’ which reflects both cultures yet at the same time adaptable to its surrounding.

Middle-eastern style of rchitectural and interior detail elements were adopted to the building with integration of cross-ventilation system and introduction of gable roof to be well-functioning in the local climate.

Each corner of both exterior and interior of the house/mansion was designed and carved with attention to aesthetical details with consideration to its functions. Design was mostly conceptualized with lots of handsketches prior to transfering the ideas to CAD drafted construction drawings.

Arches were quite heavily used to accentuate the mansion building as a ‘statement’ that the building is inspired from a mix-culture and architecture style. Repeated arches used in shaping the windows, doors, and at the porte cochere area. However, the detailing and design process was done in a way that keeps the mansion still look as a residential building and not other functions, Architect & Interior Designer Sandy Surya Sanwatri e.g. mosque or museum for example.

#1

The brief was quite clear where the Client required to have one bedroom at ground floor level to be used by occasional guests, and the rest of bedrooms (two connecting bedrooms for their children and one master bedroom) to be located at the upper level. Numbers of stories were regulated in Bintaro area to be maximum 2 storeys and not exceeding 15 meters, with front setback of 5 meters.

A fitness room is also provided at the upper floor with the view towards the swimming pool at the back of the mansion, which its design was inspired by the shape of a pyramid.

Roof is an element of a building in Indonesia which is playing an important role in a country with tropical climate with high intensity of rainfall and high humidity. The original design inspiration was to adopt middle eastern style building; However, as the architect I was able to convince the Client to use a modified ‘triangular/gable roof’ with additional of a distinguished concrete dome structure which were not sacrificing the original intent.

Although the mansion is designee as a climate-controled/air-conditioned, the ‘triangular roof’ helped in reducing heat from the sun during the day and accommodate rain and humidity. The interlocking system of ceramic roof tiles would also allow the roof to ‘breath’ and cool down the building to a certain extent. Adoption of the modified roof was resulting a unique ‘hybrid’ appearance of the mansion, which makes it stands out but at the same time goes along with its surrounding neighborhood.

Hilton Garden Inn

Public Park

Project Portfolio | Sandy Surya Sanwatri

The project is consisted of a Hotel and Public Park in a plot owned

by Omani Government. As per the agreement with Muscat Municipality, part of the parcel has to be given back to community, and in this project it was designed as public park with F&B outlet and a Tennis Court.

#2

The Hotel is G+6 and having 232 guestrooms keys.

Located in a prominent location in Al Khuwair area, accessible from two major roads. It’s location also opens towards either the mountain or sea view.

Massing design of the Hotel building was inspired by the nature and landscape of Oman. The vertical mass and curvy shape of building block layout celebrates the mountains of Oman, with the cracks that let the water flow from top to bottom of the building, as water features, on both horizontal and vertical planes. The project was designed to become an ‘oasis’ to the community, providing a ‘new’ language of architecture style, an upscale quality of a 3star Hotel, with a sizable green lushed family friendly Public Park.

Project #2 Hilton Garden Inn

Typical Floor Plan

Roof Top Plan

The Hotel’s name which contains the word ‘Garden’ was well emphisized by the rare opportunity to connect and integration of the Public Park or Garden which takes more than 60% of the overall site size.

The Hotel guestrooms are all facing either towards the North/Sea or South/ Mountain, and sun path study was done carefully to allow the cooling load effort to be in optimum performance.

On the guestroom’s windows perforated metal frames/mashrabiya was also installed to maximised shading to the wide windows of the hotel guestrooms with minimum blockage of the views.

Project #2 Hilton Garden Inn Muscat - Oman

Traditional mashrabiya screen has the aesthetic and functional design values.

The traditional Arabic Bread Oven has become the inspiration to the Show Kitchen design idea.

Project Portfolio | Sandy Surya Sanwatri

The ancient irrigation system, called “Falaj”, as old as 5000 years, has been adopted in a modern way as water features which serves it function as an aesthetic element to the hotel building, as well as the element that shall help cools down the outdoor seating of All Day Dining restaurant right beside it.

The sound that the water makes would be adding the “4th dimension” to the space.

The earthy colors of GRC facade which mimicking the local stone is a celebration of the great mountains of Oman.

Project #2 Design of Hilton Garden Inn Muscat has strongly influenced by authenticity of historical cultural elements of Oman.

Adopted as shading structure as well as aesthetical elements.

Project #3 CMA Office Tower Riyadh - Saudi Arabia

Overall KAFD Site

CMA Tower at the time was designed to be the tallest building in Riyadh, KSA (385 meters) and becomes a new landmark to the area. The super tall tower was designed by HOK together with Omrania & Associates. The tower was lately named after PIF (Public Investment Fund) Tower.

Original design perimeter (as per KAFD Urban Design Guidelines): Parcel Area: 5,962M² Parcel Utilisation: Max 85% equivalent to max 5,089M² GFA: 166,531 m² - 185,034 m² Tower Height: Min. 315 m, Max 385 m above PGL Height Restriction Plane: 21m for retail and 25m for other uses above PGL on the corner The Tower is situated on one of the main five parcels in the heart of KAFD (King Abdullah Financial District) development. Appointment of designers of each of the five tower was done through a limited tender process (participated by top international architects/ design consultants).

Project Portfolio | Sandy Surya Sanwatri

CMA Tower (as well as KAFD) is located in a main road junction in the city of Riyadh. The tower’s strategic location and its extraordinary heitht will make the CMA Tower as a new landmark along with the existing skyscrapers such as the Kingdom Tower and Al FaisaliyahTower along the city main access King Fahd road.

#3

The super tall structure was carefully designed and went through detailed calculations. Value Management/Value Engineering was done throughout the design stages, and main improvements and cost savings achieved were to include the main structural design, fins and catwalks/second-skin design and materials, facade glazing specifications, and several other items.

CMA Tower was designed and registered for LEED Gold Certification.

Building massing was designed to fulfill the design requirements by the Urban/Master Plan Guidelines which require all buildings within this zone to be faceted on all sides (some other zones were requiring facade facetation to the building facade which faces the main internal access roads.

Project #3 CMA Office Tower Riyadh - Saudi Arabia

Structure of the tower was designed to accommodate the architectural design and massing.

Vertical transportation shafts as well as the tower concrete core is placed strategically in the middle of tower section with diagonal steel tubes ‘diagrid’ structure along the building perimeter.

Tower foundation was using combination of friction pile with raft foundation was used as base, and flat slab with post-tension system was adopted for the typical tower floor slabs. There are four technical floors introduced in between the typical floors where enhancement of tower ‘structure-belt’ located and big mechanical equipments stored. Those technical floors are also the place where pipes and other network of services transfered as per design requirements.

All main buildings in KAFD are all connected at the higher podium level through sky-bridges. This would allow and encourage people movement (on foot) in a secure and comfortable walking environment (air-conditioned). Those sky-bridges was designed in such a way that people could have a view outside through some vision panels on the side of the bridge, with a fully covered top and bottom parts.

Each family member of the residents was considered for their normal daily activities which reflected in the Experience Maps as shown above.

KACARE was designed as a new settlement that may sustain itself. In order to achieve that vision, all things that required for a community to last was designed and laid out within the given site, including the residential houses, schools, hospital, work places, shopping centers, leisure facilities, etc. A power plant with nuclear reactor and photo-voltaic harvesting yards were also provided. The site was devided into two major zones, Low Land (services , power plants, and farms zone) and Up Land (residential, commercial, healthcare, education, etc.).

Project Portfolio | Sandy Surya Sanwatri

Historically, man has searched for ways and means to create desirable environmental conditions around him, for his aims and everyday activities.

The housing designs thus created have shown different solutions, developed and advanced in each historical period, to the ever-present need of building a small controlled space within the vast context of the natural environment, an environment open to the adverse conditions of sun, rain and wind.

The shape of the plot is rather long rectangular with less percentage of water-frontage. Master plan design was then devided into zones where a main ‘spine’ introduced right in the middle of the plot to ensure continuous movement of visitors starting from the entry point. The spine is called RDE (Retail Dining & Entertainment) spine. It was created as an enjoyable one-stop leisure hub, a public RDE (Retail, Dining & Entertainment) activity Spine is conceptualized to promote the vision. This Spine will also act as an integrator of the various attractions of Hayy Al Sharq. Not only the RDE Spine will accommodate commercial activities, it will also be the main Spine for PMS, PMD, Pedestrians and Teleferik. Uniquely, four thematic nodes namely Heritage, Nature, Contemporary and Futuristic nodes, will make up the entire RDE Spine, to create vibrant, active and dynamic experience for visitors of Hayy Al Sharq.

In the effort of providing a distinguished product (compare to the existing offerings in the GCC region and internationally), there is a need to invent a unique factor for Hayy Al Sharq. Taking into consideration the existing context of the site (heritage. natural terrain, physical characteristics and the aspiration of future generations of Oman), a concept of “A Journey Through Time” is envisioned for Hayy Al Sharq. The journey is set to bring different experiences for visitors & guests at every step as they wander and venture into Hayy Al Sharq, creating thematic encounters that will be memorable and unforgettable for every visitor. The RDE Spine will be the key feature of the project that will demonstrate this intent.

Project #6 NDLT (National Destination for Leisure and Tourism) / Hayy Al Sharq / The Garden Barka - Oman

As the RDE plays the integrating role, the other uses/components are planned to function interdependently from each other but will offer diverse range of uses when they are collective. It is important to ensure that the experience of the RDE remains vivacious and lively. Hence, two kinds of strategies can be set in place to keep the activities in the RDE Spine busy and eventful: Programming & Place-making Strategies. Programming optimizes usage and function while Place-making creates opportunities to encourage public involvement and community engagement.

These strategies will be useful in realizing the vision and increase the viability of the plan.

Stakeholders Engagement Workshop was held involving school students, which in its turn will become the end users of many of the components of the development, including the Theme Park, Wildlife Attraction, Equestrian Centre, Water Park, and Education-Entertainment Center.

Project #7 KAFD (King Abdullah Financial District) Riyadh - Saudi Arabia KAFD is the largest green building development in the world. The project planning and design is a combined effort of engineering design, implementation, operation and management of construction assembly, waste and recycling.

The development is having a mix of residential towers, office towers, retail spaces, and standalone attractor buildings such as conference center, museums, public library, aquarium building, education and entertainment centers, which will be connected one to another facilities by networks of sky-bridges and monorail system.

Development of all components within KAFD is regulated strictly through a Design Manual Guidelines developed by RIC as the project owner together with the Master Planner.

KAFD (King Abdullah Financial District) is projected to be Middle East’s first financial district on a scale and of regulatory and technological standards, to match the major global financial centers.

KAFD occupies 1,600,000 m2 and constitutes over 3,000,000 m2 of floor space.

KAFD site is divided into three zones, where the Residential (North) and Commercial (South) are devided by a major highway (Thumamah Road). In creating physical connection and walkable connectivity between both zones, a giant ‘bridge structure’ was introduced and dressed as a park with lush green surroundings completed with water features and places for people to hang-out around the area.

KAFD building users and residence are designed to move around in shade (climate-controled) walk path, sky-bridges, or by electric train monorail.

Vehicular movements are limited in this development. Networks of different options of people movers system are integrated between buildings.

Project #7 KAFD (King Abdullah Financial District) Riyadh - Saudi Arabia

KAFD (King Abdullah Financial District) site is blessed with an existing unique feature which is the actual ‘Wadi’ (a valley that has a river that is usually dry except when it has rained, common in desert areas). That Wadi became an integral part of the Master Plan design, preserved, controlled and emphasized as the ‘greenest’ part of the development. This gift as given by the nature would become the ‘main artery’ to movement of people around the site. The Wadi is a pleasant place to walk, sit, and gather during winter or afternoon and night time.

At each end of the Wadi some ‘Attractor’ buildings were designed and functioned as magnets that pulling and attracting people movements ensuring there will be no vacuum spots around the development. Those Attractor buildings has various functions such as Public Library, Museums, Mosque, Community Center, Aquarium, etc.

Facade design of buildings facing the Wadi were regulated by the Master Plan Design Guidelines to have certain criteria, and one of them is to be themed and to have faceted facade to articulate the Wadi and give some sense of ‘movement’ and dynamics to the area. Those buildings are having different functions (office, residential, hospitality) and have retail spaces at grade level.
