# Double-Layered Residences The 100 Windows house uses a layered facade for climate control By Amy Duong | Published 2026-08-03 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/100-windows-house References: [dezeen](https://www.dezeen.com/2026/08/03/100-windows-inrestudio-multi-generational-house-vietnam/)  The 100 Windows house by Inrestudio is a 639-square-metre multigenerational residence in the suburbs of Hanoi designed for three households across two generations. Wrapped in a terracotta-toned double-skin facade, the home is punctuated by irregular openings that create private outdoor spaces while promoting natural ventilation. The additional depth of the envelope accommodates recessed balconies, slim terraces, built-in shelving, storage, desks, and ventilation channels integrated within the walls. The ground floor connects the living, dining, and kitchen spaces to a basalt-paved patio and swimming pool, while the upper levels contain adaptable bedrooms and a second living, dining, and kitchen area. Many facade openings align with interior windows to frame views, while others are deliberately offset to increase privacy and provide shade. A rooftop terrace extends beneath a grid of terracotta-toned concrete beams that follows the pitch of the home's roof, completing the flexible residential layout.
