The Sienna Net-Zero-Haus creates to tackle homelessness and climate change is a self-supporting, solar-powered, inexpensive and compact housing solution. This air -conditioning and affordable house in Quezon City, Philippines, represents a revolutionary vision for social apartments through the integration of thoughtful design, sustainability and self -sufficiency of energy.



The Siena Home was developed with the unique tropical climate of the Philippines and prioritizes natural ventilation, passive cooling and rainwater management in order to improve comfort in the interiors and reduce the dependency on artificial cooling systems. The compact 4.5mx 5.1 m floor plan has been meticulously optimized for functionality and offers a flexible layout that grows and adapts to the families living in them.



An important architectural feature is the innovative Powershade technology of billions of millions – a progressive solar roof system that serves several purposes. In addition to the generation of clean, renewable energies, it acts as a protective heat roar, reduces the interior temperatures and improves thermal comfort. In contrast to conventional solar collectors, Powershade seamlessly integrates into the structure of the house and ensures reliable energy generation and at the same time earns a permanent roof. This does the Sienna Home Home Energy Positive, which means that it generates more electricity than it consumes, reduces the supply costs and promotes long-term energy independence. Excess power can also be stored or sold on the net, which offers additional financial benefits for homeowners.

When several Sienna houses are assembled, the innovative Powershade roof resolution transmits its role as an individual energy source and turns into a farm on the roof in the usage level, in which this common energy infrastructure promotes a feeling of collective authorization and enables the residents to actively participate in a sustainable and financially rewarding energy ecosystem.


The Sienna House is built using light prefabricated components that enable a quick collection on site and at the same time maintain durability and structural integrity. This modular approach enables scalability and makes it an ideal prototype for large -scale, inexpensive housing estates. The design also enables future extensions and gives home owners the flexibility to adapt their living space over time.

The device adheres to BP 220 Social Housing regulations and has a 3-meter setback and a 2-meter setback to ensure proper ventilation, safety and community-friendly spaces. In addition, the corner units include a 1.5-meter offset that improves privacy and accessibility within the neighborhood layouts. The Sienna House is not only a single-family house, but also in a larger sustainable community model and integrates common green spaces, pedestrian paths and decentralized supply companies. By promoting energy independence and the resistance of the environment, the project is a new precedent for affordable but high -quality high -quality housing solutions in quickly urbanized regions.

The Sienna House in Quezon City serves as a blueprint for future developments and proves that inexpensive apartments can be both architecturally convincing and socially transformative. Billionbricks takes over traditional living models and pionizes a future in which affordability and sustainability are seamlessly integrated.
