A modern multi-level house built with a spirit to enjoy the tranquility of nature and as a “meditation space”; a space that unite you and the nature, a space to escape from people and routines. From this modern multi-level house of Japanese style architecture, you will get two unique structures ideas that can be applied for your future dream house, or maybe your house remodeling project.
Modern Multi-level House Plan Layout
First unique structure is its multi-level floor concept. The multi-level floor of this modern Japanese house is like a spiral structure. The floor go up little by little surround the central internal courtyard. From entrance/genkan doma area, series of split floor go up little by little with steps, up continue to outdoor rooftop terrace, and ended at the door; the door that become access to vertical void of indoor courtyard. The spiral steps remained us of the Borobudur Temple, where a pradaksina or circumambulation rite done by circumambulate walk, and go up until Borobudur Temple peak. Every circle of Borobudur Temple path is a meditation.
The series of flor level in spiral structure inside this house is similar with Borobudur Temple’s circle path. A total of 14 pieces of floor levels structure created inside. Although the house is intended as daily living spaces not spiritual/religious space, the peacefulness atmosphere inside the house is very pronounced by the architecture detail.
Like a tiny aisle, dirt floor area of this house leads us to living area. From the living area you can see rectangular glass box of indoor outdoor courtyard structure. From the entrance doma area, if you go left, dining and kitchen area exists. The living area divided into two spaces activities. First is TV area with sofas. Next to it with upper floor structure, a tatami area exists. While not in use, the tatami area hidden; series of sliding panels become partition walls that separate tatami space from TV area. Between TV sofa area and tatami area, there are steps that lead us to next floor level of the house. The kitchen design of this Japanese architecture house is like a counter stall of a Japanese bistro. Semi basement area is wooden structure workspace.
Unique Internal Courtyard as Open Drainage Structure
Second unique structure of this private dwelling is its internal courtyard. Placed in the center of the house, the internal courtyard has void vertical structure with no roof as a lid. With indoor courtyard openings, natural light and air freely enter whole interior of the house.
With no lid or transparent roof to cover the chimney-shaped vertical ventilation structure, rainwater easily enters to the house. What? Yup, it is indeed intentional. The indoor courtyard along with its rectangular vertical void designed so rainwater freely enters inside the house. Therefore, dweller can enjoy the rain and the fall of rainwater when they do activities inside the house.
A garden with vegetation that usually created on the base of courtyard abolished. In exchange, open drainage system with leveling structure created. There are two level of courtyard base. So when the rainwater enters the house, it will fall on first concrete floor. First concrete floor has hole located at the center of floor. The rainwater then flow through the center hole and fall to second concrete floor. From the second base concrete floor, the rain flow at side of rectangular glass volume then go to sewer. When there is no rainy season, the both stacked concrete floor of courtyard can be accessed and become outdoor seating. The built-in rectangular glass is a part of courtyard vertical structure. Because of the rectangular glass volume, the fall and drops of rainwater can be enjoyed inside the house.
While the interior of this unique split-level home seems complicated with its series of floor level structure, the exterior appearance really modest; just like other ordinary contemporary Japanese house. The exterior design of this modern detached house is really simple. Corrugated metal become wrapping materials. The facade design of this modern multi-level house has portico structure.
Simple materials and decorating applied for this house interior design. With wooden construction, hardwood flooring installed. Certain concrete structure exposed with no polish.
