Concept

一畳十間是以提供"日式优雅的舒适生活"为主题的设计服务

我们很珍惜日本人在生活中日积月累的智慧,常年被人们使用以及喜爱的材料。

我们使用独特的细节来处理这些材料,把日本传统住宅建筑中累积的智慧和经验结合到现代的生活方式里,希望能突破现在一成不变的nLDK生活,回归到更丰富多彩的居住环境。

手工精心创作的空间能激发人们的创造力,使其感受到更多的温馨。而我们的使命是帮助 人们打造出一个能在日常生活中放松心情,修养身心的生活环境。

ichijo-toma is a lifestyle design service inspired by the elegance and comfort of traditional Japanese living.

We value the wisdom cultivated over centuries in everyday Japanese life, and we honor the timeless beauty of natural materials that have been long respected.

In contrast to the uniformity of today’s standard apartment layouts, our mission is to bring warmth, variety, and character back into daily life.

By integrating handcrafted elements into a space, we cultivate a sense of creativity—creating environments where people can truly relax, feel at ease, and find quiet joy in everyday life.

Design

Materials

材料

Most people nowadays tend to choose the most standard finishing materials just for convenience, and this resulted the increasing likeness of all recently developed residential spaces.
On the contrary, ichijo-toma appreciates the aesthetics that prospered from the traditional Japanese culture; therefore, we are more inclined to use materials that are appropriate to convey the local ideology.
Let the gentle atmosphere created by light and touch harmonize in time, evolve and finally become a part of the family, together creating a more abundant life.

当下的人们为图一时便利,纷纷选用清一色的家居建材,这直接造成了现下四处可见的同质化住宅空间。
一畳十間更重视的是传承日本风土所孕育出的美学文化,更倾向于选择适用于当地的自然材料。
随着时间的推移,触感和光线之间的亲和性所带来的感受将和住户的家庭一同慢慢变化,融为一体,创造出更加丰富的生活。

Keiso-do (diatom mud)

The shadow created by the coarse texture of diatom mud constructs a tranquil and pleasant atmosphere, bringing people the emotions of Japan with the imagination of living in the natural landscape.

硅藻泥

硅藻泥粗糙的质感所形成的光影关系能营造出静谧舒适的空间氛围,能让人体会到日本的四季风土,想象生活在自然的土地上。

珪藻土

Wood

Natural wood is composed of an infinite number of elements, and its expression delivers livelihood to the household while balancing the quality of life. The presence of natural wood exerts a subtle influence on the family, changing with them as time goes on.

木材

原始木材本身就由无尽的元素所构成,它的这种特质能在赋予生活稳定性的同时带来新的生命力。木材的余韵和存在感潜移默化地影响着家庭成员们,并随着时间的推移,与他们一起变化。

木材

Doma (floor at entrance)

This transitional space at the entrance is tiled with natural pebble stones which convey a sense of delicacy and peace. Their unique texture creates a relaxed yet elegant welcoming space.

土間 (玄关的地面)

铺设天然的鹅卵石而成的玄关过渡空间散发着优雅宁静的氛围。鹅卵石独特的质感营造出了低调却也大方得体的迎宾空间。

土間

Tatami

The softness breathes nostalgia and peace when stepped onto it. Tatami rooms have many ways to use; they can become comfortable guest rooms covered with bedding, or become children’s rooms as the kids grow up.

榻榻米

脚踩在上面时的温柔触感营造出怀旧而安稳宁静的时光。榻榻米房间的使用方法有很多种,比如铺上被褥作为客卧,或随着孩子的成长,作为个人的房间来使用。

珪藻土

Washi

Japanese styled sliding doors with washi paper will allow the guests immerse in the most exquisite and sophisticated aesthetic traditions of Japan. Direct sunlight is diffused through the washi paper, creating a tender and cozy atmosphere.

和纸

使用和纸的日式推拉门会让人亲身体会细腻精致的日本美学,以及具有可变性的多样化空间。强烈的阳光透过和纸后散开,变成柔和的光线照亮室内,营造出朦胧柔和的空间。

木材

Tile

Each tile is different from one another, unique in its shape and color. Its mild touch and silky texture add a drop of vibrant spirit into the space.

瓷砖

在窑炉中烧制而成的瓷砖,每一片都有独一无二的颜色和外形。温暖的触感和光滑的质感为空间增添了几分灵动和生气。

土間

一畳十間为每一位客户定制美观、实用、且便于使用的原创家具。它们将与建筑融为一体,不浪费任何一处空间。

造作家具の話

Lighting Design

Another day full of bright and lively morning sunshine. Dim the lights and enjoy the quiet evening catch-ups at the end of a long day. Peaceful self-time trying to focus on a particular moment.

照明设计

阳光明媚、充满活力的清晨时光。点上灯,在一天结束时享受愉快对话的夜晚时光。集中精力专注于某件事物的宁静时光。通过给灯光赋予不同的特点,可以尽情享受灯光所带来的多样化空间。

照明の話

Plan Layout

平面布局

Japanese people in the ancient times mostly lived in houses where the rooms divided and connected with sliding doors. This made them more considerate about the family members that live with, paying more attention to their inter-family relationships.
The way ichijo-toma lays out the rooms also respects the value of having a comfortable and healthy relationship among family members.
Some clients only seek the maximum numbers of room, but we advocate for the simple lifestyle like that of the families in the old days. On top of ensuring each family member has his/her own space in the house, a good plan layout guarantees a pleasant yet flexible and versatile lifestyle while subdividing the house into a minimum number of rooms.

古时的日本人大多生活在一个被分割的大空间里,用推拉门作为房间之间的连接。因此他们需要照顾一起生活的人的感受,更加重视生活中人与人的关系。
一畳十間的平面布局设计也是以重构家庭人际关系,创造舒服良好的家庭环境等理念为主旨。
很多客户单纯的追求房间数量,然而我们更提倡像古时候的人们一样简单的生活方式,确保在一个宽敞的空间中,让每个家庭成员都能找到属于自己的场所,用最少的房间数量保证一家人能充分享受生活的乐趣与丰富的空间体验。

Winding Path

Like the looping and meandering trails, you can discover the surprises in a variable of spaces while walking around the house. Free-formed plan layout can create a space full of curiosity, as well as a well- ventilated environment.

洄游性

如同循环往复的步道一般,可以在行走的过程中发掘空间变化带来的喜悦。自由的平面布局能让人与新的光景不期而遇,并营造出通风良好的生活空间。

回遊性の話

Individual Room

Some spaces are more comfortable because of their small sizes. We believe that the size of each room should be dictated by its function, so we will eliminate all unnecessary elements while maintaining the minimum area necessary for each space, boldly dividing and creating enjoyable small spaces.

个室

有的空间因为小所以才更舒服。空间的大小应该根据具体用途和功能而定,所以我们会根据所需功能的最小限度去掉多余的元素,大胆的分割并营造出舒适的小空间。

個室の話

Without Corridors

We will eliminate the corridors that are only there as a division between rooms. Some storage or a small reading room can subtly fit in even the narrowest space, scattering the different life-essential areas throughout the house.

没有走廊的设计

我们会去掉单纯为隔开房间而设的走廊。再窄的空间也能够巧妙地嵌入收纳或小型书房,让生活所需的空间分散在房屋各处。

At a date of your desire, we can schedule an individual meeting with you, either in person or online. We would like to get to know you and your style of living, as well as any thoughts on your construction budget and schedule. It would be the most helpful if you could share with us the project’s architectural drawings or photographs.

我们希望在您提出的候选日期中,与您进行单独的深入了解。(线上或线下均可。)届时,我们希望能了解您对生活方式,施工周期与预算方面的需求和想法。如果您能够提供现场的图纸和照片等资料,我们还能聊到更具体的内容。我们还会向您详细介绍一畳十間的设计理念以及工作流程等等。谈话过后,我们还希望带您去参观已经完成的项目。

Step 4. Site Survey

Step 4. 现场调查

We would like to visit the site to check the current conditions of the house in order to make realistic projections about the project. Construction cost and schedule will also be discussed at the time. Transportation fee will be at the cost of the client if the project is located outside the Kanto area in Japan or the metropolitan Shanghai in China.

我们需要到现场查看真实的房屋建筑,确认能否在现有的环境下实现您的需求。届时,也会和您谈到施工费用、工期等。在日本关东圈外或中国上海市以外的项目,需要客户另付交通费。

Step 5. Design Contract Signing and Start of Design

Step 5. 签署设计合同,开始设计业务

We will proceed to the contract signing process after completing steps 1-4. We will spend the following 2-3 months working closely with you on refining the design to meet your needs and expectations.

在完成上述1-4的Step ,双方签订设计监理合同后,我们会花上2到3个月时间多次听取客户的需求和想法,一步步推进您所希望的设计、材料等。

Step 6. Construction Contract Signing and Start of Construction

Step 6. 签署施工合同,开始施工

Getting the quote for construction cost and adjusting it to fit within your budget will take approximately 2 weeks to 1 month. The client will sign the construction contract once the final quote is adjusted and accepted. Construction will start immediately after completing any necessary reports or communications with the apartment/neighbors. ichijo-toma will be responsible for site supervision, making sure the construction keeps going on schedule. The construction process usually takes about 3 months, but it could vary based on the scale of the project.

对于报价单的审查,以及根据需要更改调低报价方案需要2周到1个月左右的时间。最终决定报价金额及设计后,在与施工单位签订施工委托合同,并向居委会和邻居报备后方可开始施工。我们将负责现场监理,监督施工是否按计划进行。施工工期约三个月左右,但也会根据具体的施工规格而异。

Step 7. Completion and Project Hand-Over

Step 7. 项目竣工并交付

After completing a series of rigorous inspections with the client present on site, we shall call an end to the project and handover the house.

通过与客户一起在现场进行严格的检查程序后,项目正式完工并交付。
