'ACB living' shared office space by lighthouse in nagasaki, japan

‘acb living’ by lighthouse

Within the small town of Ashibeura in Nagasaki, the Japanese practice Lighthouse was invited to design the new spaces of ACB Living, a cafe and co-working hub that provides off-site training for several companies. Responding to the local problem of vacant lands, the architects decided to disperse the functions of ACB Living across the town — including training rooms, reception areas, and shared office spaces.

By doing so, not only are forgotten spots revitalized, but spontaneous interactions with locals are bound to unfold while office users walk through different streets and corners: ‘The spatial format attempted here does not limit the program in this town. Works for both homes and shops. This is a proposal for a new lifestyle in which people are loosely connected throughout the region,’ writes the practice.

blurring the boundaries

Regarding the main headquarters, Lighthouse (see more here) resorted to minimizing the interior area of ACB Living across both levels and maximizing outdoor space at the far end of the site for efficient energy consumption. Considering the surrounding three buildings and climatic conditions, the team searched for a form that would enable optimal use of natural energy in this location. For example, the space where office users can see from the front street to the neighboring building in the back was designed based on wind passage.

Moreover, the outdoor space reveals no outer walls, only a cloaking of agricultural sheets that can be opened and closed, making it possible to adjust the amount of light and wind that penetrate the building. As a result, the softly swaying sheet visualizes the wind and obscures the site boundaries.

‘Here, the site boundaries are ambiguous, and the intention is to create a relationship in which the surroundings are slightly dependent on each other. The space set up in the gaps of this town is gently connected to it along with the noise that is different from the mechanical sounds of the city (the activities of people in the town, the voices of birds and insects), and the pleasant breeze that blows through,‘ shares Lighthouse.
