走在御堂筋的主要街道上，到了有中高层住宅和商业建筑的地区，突然出现了一个住宅区，里面密密麻麻的都是两层的木制房屋。YMT-house位于这个地区，面积只有49.5平方米，有4米的开放宽度和11米的深度。在这种有限的条件下，客户首先需要宽敞的客厅，供四口之家使用，然后是私人房间，足够的储藏室，以及屋顶。为了在满足所有这些要求的同时丰富和提高生活方式，该项目注重每个房间之间的规模差异。

Walking down a Midosuji main street to the area with mid-to-high-rise residential and commercial buildings, suddenly a residential area filled densely with two storey wooden houses appeared. YMT-house is located in this area and measures just 49.5 square meter with 4m open width and 11m depth. In this limited condition, the client firstly required spacious living room for family of four, and then private rooms, enough storage, and the rooftop. To enrich and enhance life style while meeting all these requirements, the project focuses on the scale difference between each room.

浴室位于一楼，而客厅位于一楼和楼上。客厅和一楼的厨房空间有大约1.4米的高度差，这使得一个LDK逐渐被划分为两个独立的空间。房间中间的阶梯式地板创造了多种多样的视线，它可以作为孩子们的游乐场或多功能活动空间，给日常生活带来刺激。在LDK上面的一个床位只有三张榻榻米的储物空间，而孩子们的房间大约是四张榻榻米，并配有书桌和两个人的床。为了最大限度地减少每个私人房间的家具垂直存储，创造宽敞的LDK的特点是开放的天花板，家人聚集在这里。

Bathroom is located on the ground floor and the living room is on the first and above floor. There is about 1.4m height difference between living room and dinging and kitchen space on the first floor which gradually divide one LDK into two separate space. Step-wise floor in the middle of the room create variety of sight view and it can be used as playground or multi-functional activity space for kids bringing excitement in daily life. A bed room above LDK is just three tatami-mat with storage, and kids’ room is about four tatami-mat with furnished desks and beds for two. To minimizing each private room by furnishing vertical storage enable create spacious LDK features open ceiling, where family gathered.

寝室上部的一半是储藏室和书房的组合，其余的空间提供了通往屋顶的楼梯。延伸的墙面没有扶手，而是创造了一个封闭的空间，促进了通往天空的流畅的视觉轴线，同时隔绝了他人的目光。作为第二个客厅，这个户外空间可以用于各种活动，如烧烤或为孩子设置充气游泳池。

Half of the upper part of the bed room is a combination storage and study room, the rest of space provide staircase to rooftop. Instead of having handrail, the extended wall creates enclosed space which promote smooth visual axis to the sky while shutting out from gaze of others. As a second living room, this outdoor space can be used for variety of activities such as BBQ or setting inflatable swimming pool for kids.

关于房屋结构，没有走廊，但大部分房间都直接连接到楼梯。这个楼梯不仅是一个垂直的移动线，而且还提供了一个封闭的空间来阅读书籍或休息。像家具一样，客厅和其他私人房间的阶梯式地板，包括卧室、儿童房和书房，都是用日本柏树制成的，它可以直接接触到皮肤。在狭窄的空间里体验建筑和家具之间的尺度差异，创造出视觉错觉，这有助于改变LDK和天台的空间感。

Regarding to house structure, there is no corridor but most of the room are connected directly to the staircase. This staircase is not only functioned as a vertical moving line but also provide enclosed space for reading books or having a break. Like a furniture, step-wise floor at the living room and other private rooms including bed room, kids’ room, and study room are made with Japanese cypress where it could get direct contact with the skin. To experience the scale difference between architecture and furniture in the narrow space creates optical illusion, which help transform LDK and rooftop feel more spacious.

尽可能地减少空间，同时最大限度地利用客厅的空间，这种尺度差异的体验为小户型设计提供了新的可能性。

To make the most of the space by minimizing space as much as possible while maximizing the space for living room, and this scale difference experience suggests new possibility of small house design.
