The work was built in Thai Nguyen province by the architects of AD + studio. The concrete frame system of the two main building blocks is retained, reinforced by trusses because the roof structure steel truss is inspired by the surrounding context, creating a space that exceeds the span. This solution both frees the view of the area below to the garden, while increasing the used area above, and at the same time creating a harmonious “stack of roof” building in the whole. Standing in front of the house, through the glass brick wall between the green pavement and the front garden, the inner and outer division seems to be only approximate. The old building blocks a portion of the area for the garden and vegetation as adding a buffer between the bustling highway outside and the quiet living space inside. Narrow corridors connect the common space in front and the private space of the homeowner in the back. From each point in the house, you can see many different spaces. The living space and the green trees of the garden blend together, creating an airy atmosphere. In the house, the group of architects opens up a sky well to catch the light. Besides ventilation, the house is also full of comfort and modernity in daily life. The spiral staircase and the large spaces create a strong visual impression in the house. The materials and design styles are a bit nostalgic but still ensure high applicability. Works as a background of harmony between context, nature and people. The shield roof is made up of two layers of colored tole placed on the glass ceiling, creating an air convection zone, limiting the heat to the functional areas while retaining the feel of the structure.
