Bahay Sibi

Platform 21 Architecture as Architects

Nestled in a 300-sqm corner property in Baliuag, Bulacan is BahaySibi, a three-storey residence made of wood and concrete. Emboldened concrete volumes offer a dynamic play in form, balanced by the warmth from its wooden eaves, exterior paneling, and unique sun shading. An interesting interplay of façade is observed at its two fronts, morphing from individual volumes made cohesive by its recurring brisesoleil, reminiscent of the house’s namesake—the sibi.


To create a house representative of the Filipino archetype is what Platform 21 Architecture’s intended for BahaySibi. The sibi, an extension of the roof over a window, is a key component of the bahaykubo—a well-known Filipino vernacular home. The sibiacts as primary weatherproofing, from heavy rains to intense sunlight, and is an important component for architecture in tropical locations. Guided by this principle, Platform 21 Architecture molded the sibiinto a modern home, breathing their own interpretation for a more contemporary approach.


With the property primarily facing North and East, ample light from the morning sun was taken into consideration. Major spaces such as the living and dining areas were respectively situated along the East and North sides of the property, with the garden and lanai situated along the northeast. Fenestrations were designed to accommodate ample sunlight and wind. In order to address intense heat during the day, the initial iterations of the sibican be seen along the fenestrations of the major public spaces, providing light and keeping out heat.


The spacing of the sibi-patterned brisesoleil extends upward, towards the second floor, where it continues to shade the bedrooms overlooking the North and East roads. Armed with its simple and efficient layout, the bedrooms have been adequately positioned to maximize vistas and views, vis-à-vis maintaining a modicum of privacy.


From its strong wood and concrete exterior, BahaySibi evolved into a haven of warmth interior spaces. Light, airy, and bright, the interior space of BahaySibiboasts of a streamlined plan that maximized functionality and multi-dimensionality of spatial use, anchored with the principle of interrelating spaces to encourage mobility and intermingling. The open plan on the ground floor provided an unobstructed flow to multiple activities within the household. Simple, clean, and efficient lines are balanced with warm oak tones. This delicate balance is best exemplified by the contrast between the lightly-colored tiles and the wooden wall paneling, as well as the streamlined open-stringer staircase made out of solid oak planks. These elements in the interior space are in harmony with the house’s exterior, providing a continuity in its design and planning.


Platform 21 Architecture has shown a mastery of continuity in its utility of materials, harmonization of space and volume, and careful yet bold iteration of vernacular architecture into contemporary form. BahaySibi is an example of how basic concepts can be learned from early Philippine architectural origins and be evolved to accommodate modern requirements and aesthetic. Through clear understanding of architecture and planning, as well as a respectful homage to vernacular roots, Platform 21 Architecture has exemplified their prowess in creating a residence that is both magnificent yet subdued, focused on the necessities of its end users without compromising identity and artistry.
