This 5 Bedroom Penthouse Type PH at Stack 18 in Tembusu Grand is a completed residence presented as an in-situ showflat. Unlike a temporary showflat constructed within a sales gallery, buyers can experience the unit’s real ceiling heights, finishes, views and spatial proportions exactly as they would receive them.
The Tembusu Grand penthouse is ready for immediate occupation and currently available for sale at $7,888,000. Its key highlights include a dramatic double-volume living and dining area, separate wet and dry kitchens, five bedrooms, multiple ensuite bathrooms, an extensive service zone and a broad balcony overlooking the surrounding neighbourhood.
A Dedicated Entrance Foyer
The main entrance of the Tembusu Grand penthouse opens into a dedicated foyer that creates a gradual transition from the common corridor into the private residence. Instead of revealing the entire living area immediately, the entrance passage provides a degree of separation and privacy before the home opens into its principal communal spaces.
Timber-effect wall panels line the foyer and establish the warm contemporary palette carried throughout the penthouse. A recessed display niche provides a convenient surface for decorative objects, keys and other daily essentials, while a circular feature mirror reflects light and adds visual depth.
The foyer is sufficiently wide for residents and guests to enter comfortably, an important consideration for a five-bedroom home intended for a larger household. Large-format marble flooring then continues from the entrance into the living and dining areas, creating visual continuity throughout the main communal zone.
Dual-Access Wet Kitchen Beside the Entrance
Positioned immediately beside the main entrance, the wet kitchen provides a separate environment for heavier cooking. This arrangement allows residents to prepare more elaborate meals without exposing the open-plan living and dining areas to cooking fumes, heat or clutter.
One of the most practical features is its dual-access configuration. The first entrance is beside the main foyer, allowing groceries to be brought directly into the kitchen without passing through the formal living spaces. The second entrance connects the wet kitchen to the dry kitchen beside the living area, creating an efficient route for food preparation, cooking and serving.
Configured as an elongated galley kitchen, the space makes effective use of its length. A continuous stone worktop incorporates the sink and gas hob, while the full-height stone backsplash provides a durable and visually cohesive finish. Upper and lower cabinetry offer substantial storage, with under-cabinet lighting illuminating the preparation surfaces.
On the opposite side, full-height cabinetry accommodates the refrigerator and additional pantry storage. There is also sufficient clearance between both sides of the kitchen for more than one person to work comfortably.
Yard, Household Shelter and Service WC
The wet kitchen leads to a dedicated yard that consolidates the laundry, storage and household functions within a self-contained service zone. Keeping these activities away from the formal areas helps the living and dining spaces remain presentable and uncluttered.
A window at the end of the yard introduces natural light and ventilation. The area connects directly to the household shelter and a separate WC with shower facilities, allowing the back-of-house functions to operate independently from the rest of the home.
Fitted Household Shelter
The household shelter has been fitted out as an organised utility and storage room rather than left as a basic enclosed space. Open shelving makes use of the vertical height, while hanging rails, drawers and counter surfaces provide storage for clothing, linens, cleaning supplies, luggage, seasonal items and pantry overflow.
The counter can also support laundry folding or general household organisation. For a larger family occupying a five-bedroom penthouse, this additional storage capacity can be particularly valuable.
WC Beside the Yard
The WC beside the yard includes shower facilities, allowing it to function as a complete service bathroom rather than only a toilet. Its location is convenient for a domestic helper or household members carrying out cooking, laundry and cleaning activities.
By grouping the yard, household shelter and service WC together, the Tembusu Grand penthouse establishes a functional back-of-house area without compromising the presentation of its main living spaces.
Dry Kitchen as the Social Centre of the Home
The dry kitchen anchors the open-plan entertaining area and serves as the interface between the wet kitchen, dining room and living space. Its central position allows hosts to prepare refreshments or light meals while remaining connected with family members and guests.
A substantial natural-stone island forms the centrepiece of the kitchen. Finished with waterfall edges and an integrated under-mount sink, the island provides a broad surface for food preparation, serving and casual dining. Bar stools allow it to function as a breakfast counter, informal workspace or gathering point during social occasions.
Behind the island, a long built-in counter provides additional worktop space and storage. Glass-fronted display cabinets introduce visual depth, while full-height cabinetry houses the built-in ovens and keeps appliances neatly integrated.
The direct connection to the wet kitchen allows heavier cooking to remain enclosed, while the dry kitchen stays visually presentable as part of the main entertaining area. This separation is especially useful for households that cook frequently but still want an open-concept communal space.
Double-Volume Living and Dining Area
The defining architectural feature of this Tembusu Grand penthouse is its double-volume living and dining area. The increased ceiling height creates a sense of grandeur rarely encountered in conventional condominium units and gives the communal space an atmosphere closer to that of a luxury landed residence.
Full-height windows extend across the frontage, supplemented by clerestory glazing above. Together, they draw natural light deep into the interior and accentuate the vertical proportions of the room. Floor-to-ceiling sheer curtains soften the daylight, while concealed cove lighting and curved ceiling detailing add architectural interest after dark.
The dry kitchen, dining area and living room remain visually connected, but each zone is clearly defined through furniture placement, lighting and material treatment. This gives the home the openness of a contemporary plan without making the different functions feel indistinct.
Dining Area
Positioned between the dry kitchen and living room, the dining area comfortably accommodates an eight-seater dining table. Its generous proportions make it suitable for everyday family meals, festive celebrations and formal entertaining.
The location beside the dry kitchen allows food to be served conveniently, while the direct connection with the living room enables conversations and gatherings to flow naturally between both spaces. Sculptural pendant lights define the dining zone and provide an elegant focal point without disrupting the openness of the room.
Full-height glazing beside the dining table introduces abundant daylight and creates a visual connection with the balcony. Wide circulation paths around the table ensure that chairs can be pulled out comfortably without obstructing movement through the home.
Living Area
The living area is planned to accommodate a substantial lounge arrangement while preserving generous circulation. A large sectional sofa, occasional chair and coffee tables can be positioned comfortably without making the space feel congested.
A feature artwork/TV wall with a floating console provides the main focal point, while timber wall finishes add warmth against the pale marble flooring. The nearby dry-kitchen island strengthens the social connection between cooking and relaxation, allowing conversations to continue across the two zones.
The double-volume ceiling and extensive glazing give the living room an exceptional sense of openness. The clerestory windows bring additional daylight into the upper section of the room, while full-height curtains emphasise its vertical scale.
This combination of space, natural light and direct access to the balcony makes the living area suitable for both quiet family use and larger gatherings.
Expansive Balcony
The balcony extends along much of the penthouse frontage and is accessible through full-height sliding doors beside the living and dining areas. Its generous depth allows for outdoor seating, planters and occasional tables while preserving clear circulation.
A deep roof overhang offers shelter from direct sun and rain, making the balcony usable in a wider range of weather conditions. Glass balustrades preserve views towards the neighbouring developments, landed housing and the wider urban landscape.
Finished with timber-look outdoor tiles, the balcony serves as an outdoor extension of the principal communal spaces. When the sliding doors are opened, the living room and balcony can operate as one continuous setting for entertaining, alfresco refreshments or relaxed everyday use.
Transition Area and Guest Powder Room
Beside the dining room is a transition area connecting the communal spaces to the junior master bedroom wing. Timber panelling continues the material language established at the entrance, while a floating bench and circular mirror turn the circulation area into a more purposeful feature.
The guest powder room is positioned nearby, allowing visitors to use the bathroom without entering the family’s private bedroom zone. Full-height marble-effect tiles create a refined backdrop, complemented by a stone vanity, vessel basin and broad mirror.
Concealed lighting and integrated shelving provide both ambience and practical storage. Although designed mainly for guests, the powder room is finished to a standard consistent with the rest of the Tembusu Grand penthouse.
Private Bedroom Wing
Junior Master Suite
The junior master suite is set back from the main communal spaces through a short entrance corridor. This creates a greater sense of privacy and allows the room to function as a self-contained suite for elderly parents, adult children or long-term guests.
Junior Master Wardrobe
Before entering the sleeping area, residents pass through a dedicated dressing zone. Open shelves and drawers on one side provide both display and concealed storage, while full-height mirrored wardrobes opposite maximise capacity and visually widen the passage.
Integrated lighting illuminates the wardrobe interiors, and the mirrored surfaces reflect daylight from the bedroom windows. Locating the wardrobes outside the principal sleeping area also helps the bedroom remain calmer and less cluttered.
Junior Master Bedroom
The junior master bedroom accommodates a queen-sized bed with bedside furniture on both sides while retaining comfortable circulation. A full-width upholstered headboard introduces softness, while floating display shelves provide space for books and decorative objects without occupying the floor.
Full-height windows bring in natural light and elevated neighbourhood views. Sheer curtains diffuse the daylight, while blackout curtains provide greater privacy and light control when required.
Warm timber flooring differentiates the bedroom from the marble-finished communal areas and contributes to a more restful atmosphere. Together with the dedicated wardrobe and ensuite bathroom, the room functions as a genuine junior master suite rather than a conventional secondary bedroom.
Junior Master Bathroom
The ensuite bathroom continues the marble-inspired design language used throughout the unit. Large-format tiles create a seamless appearance, while the long stone vanity incorporates twin countertop basins that allow two users to prepare simultaneously.
Mirrored cabinets offer concealed storage, while an open niche keeps frequently used items accessible. The shower is enclosed behind frameless glass and fitted with both an overhead rain shower and handheld shower set.
The separation between the vanity, WC and shower makes the bathroom practical for everyday use while retaining an open and refined appearance.
Bedroom 4
Bedroom 4 is located closer to the living area, at the opposite bedroom wing from the junior master suite. Although designed as a bedroom, the in-situ showflat presents it as a private lounge and reading room.
A curved sofa, low table and sculptural pendant light illustrate how the room can be adapted as a home office, media retreat, playroom or quiet sitting area. Alternatively, it can be furnished as a conventional bedroom for a child, guest or elderly family member.
Full-height windows introduce daylight, while the textured feature wall adds visual interest. Built-in wardrobes beside the entrance provide hanging space, shelves and drawers without intruding significantly into the usable area.
Bedroom 3
Bedroom 3 is presented as a compact children’s room with a single bed, wardrobe and study desk. The efficient layout combines sleeping, storage and study functions while maintaining sufficient circulation.
A full-height window brings in natural light, while blinds and curtains allow residents to regulate privacy and brightness. The upholstered headboard, integrated lighting and playful artwork demonstrate how the room can be personalised for a younger occupant.
Warm timber flooring and neutral finishes maintain consistency with the rest of the bedroom wing. The room could also be adapted as a guest bedroom or study-bedroom for an older child.
Bathroom 4
Bathroom 4 is positioned along the common bedroom corridor and serves Bedrooms 3 and 4, as well as visitors when required. Its shared position allows both bedrooms to use the bathroom without passing through another private room.
Large-format marble-effect tiles cover the walls and floor, while a stone vanity with an integrated basin provides a practical preparation area. Mirrored cabinetry conceals toiletries, and open shelving keeps frequently used items accessible.
A frameless glass screen separates the shower from the dry area. The shower area includes a handheld fitting, while the nearby window provides natural light and ventilation.
Bedroom 5
Bedroom 5 is another efficiently planned secondary bedroom, distinguished by full-height corner glazing and elevated views. Although compact, the dual-aspect windows make the room feel noticeably brighter and more open.
A single bed is positioned against a textured feature wall with concealed lighting and a sculptural wall sconce. A curved integrated ledge replaces a conventional bedside table, providing a surface for books and personal belongings without consuming additional floor space.
Full-height wardrobes occupy one side of the room and provide substantial storage. Depending on the family’s needs, Bedroom 5 could serve as a child’s bedroom, guest room or private study.
Bathroom 3 – Ensuite to Bedroom 5
Bedroom 5 benefits from its own ensuite bathroom, allowing it to function as a self-contained suite. Bathroom 3 is finished with grey marble-effect tiles and includes a long vanity with an integrated basin.
Mirrored cabinets and open shelving offer a combination of concealed and accessible storage. The frameless shower enclosure separates the wet and dry zones, while the window introduces daylight and ventilation.
The inclusion of an ensuite gives Bedroom 5 additional flexibility, making it suitable for an older child, long-term guest or family member seeking greater independence.
Master Suite
Private Entrance and Walk-In Wardrobe
The master suite is positioned at the end of the bedroom wing, giving it the greatest degree of separation from the main entertaining areas. Instead of opening directly into the sleeping area, the entrance leads through a dedicated dressing passage.
Full-height wardrobes line both sides of the transition zone, incorporating hanging rails, drawers, shelving and overhead storage. Open compartments provide easy access to frequently used items, while mirrored doors opposite reflect light and visually broaden the corridor.
Integrated LED illumination gives the wardrobe area a boutique-inspired atmosphere. This arrangement also keeps clothing storage away from the sleeping space, allowing the master bedroom to retain a calmer and more organised character.
Master Bedroom
The master bedroom comfortably accommodates a king-sized bed with bedside furniture on both sides while preserving generous circulation. Its layout combines the sleeping area with a separate dressing table, giving the room additional functionality without compromising its spaciousness.
A bespoke headboard wall formed by vertical timber fins, mirrored panels and concealed lighting creates the principal focal point. The mirrored elements introduce depth, while the integrated illumination provides a warm hotel-inspired ambience.
The dedicated dressing table features a marble-effect countertop, circular mirror and decorative pendant lights. It can also function as a writing desk or occasional workspace.
Full-height glazing introduces abundant natural light and elevated views. Sheer curtains soften the daylight, while heavier drapes provide privacy and light control. Warm timber flooring and neutral finishes reinforce the restful character of the room.
Together with the walk-in wardrobe and ensuite bathroom, the bedroom forms a complete private suite in which dressing, sleeping and bathing functions remain clearly defined yet closely connected.
Master Bathroom
The master bathroom is considerably larger and more elaborate than the other bathrooms, with separate vanity, shower, bathtub and WC zones. Large-format white marble-effect tiles wrap the walls and create a bright, continuous appearance.
Vanity Area
Two long dark-stone vanities are positioned on either side of the entrance, each fitted with a sculptural vessel basin and wall-mounted mixer. Full-height mirrors above the vanities reflect light throughout the bathroom and visually enhance its sense of depth.
Vertical integrated light strips provide balanced illumination for grooming, while open shelving beside the mirror accommodates toiletries and decorative objects. Dark timber framing introduces warmth and contrast against the lighter marble surfaces.
Bathtub with a View
A full-sized built-in bathtub is positioned beneath a large picture window, allowing residents to enjoy elevated neighbourhood views while bathing. The window also introduces considerable natural daylight, contributing to the bathroom’s bright and spa-like atmosphere.
A contrasting dark-stone surround frames the bathtub and provides useful ledges for bath products and decorative accessories. The bathtub occupies its own zone, allowing it to be used without interfering with the vanity or shower.
Shower and WC
The shower is enclosed behind a frameless glass screen, preserving the bathroom’s visual openness while containing the wet area. It includes an overhead rain shower, a handheld shower set and a built-in shelf for bath products.
Natural light from the adjacent window reaches both the bathtub and shower zones. The WC is positioned separately, supported by a slim ledge that provides a practical surface without requiring bulky cabinetry.
The combination of panoramic glazing, extensive marble finishes and clearly separated functions gives the master bathroom the atmosphere of a private hotel spa.
