项目位于湖南省长沙市的后湖艺术园内，改造前为一栋三层民宅，主体结构为砖混结构，采用石灰砂浆的空斗砌法，且无圈梁构造柱，结构稳定性相当薄弱，但园区管理单位禁止拆除重建，只能在原有民宅基础上进行改造，因此业主希望通过建筑更新改造，将其转化为一所富有外立面特征的设计办公室。

The project is located in the Houhu Art Park in Changsha City, Hunan Province. Before the renovation, it was a three-story residential house. The main structure was brick-concrete structure. The empty bucket masonry method of lime mortar was used. There was no ring beam structure column, and the structural stability was quite weak. But the park management unit prohibits the demolition and reconstruction, and can only carry out reconstruction on the basis of the original houses. Therefore, the owner hopes to transform the building into a design office with rich facade features.

新老结构的“套娃”处理

" matryoshka " of New and Old Structures

业主首先面临的困难，是如何在这个比较薄弱的砖混结构的基础上，再加上两层办公的体量。为了不影响原有结构，我们将新增的三四层的承重结构，跨越原有的一二层砖混结构，形成了一个类似“套娃”的结构加固方案，这种新结构嵌套老结构的承重方式，保证了新老结构各自的安全和稳定性，同时也为重塑建筑外立面表情提供了最大的设计自由度。

The first difficulty the owner faced was how to add a two-story office volume to this relatively weak brick-concrete structure. In order not to affect the original structure, we added a three- and four-story load-bearing structure across the original one and two-story brick-concrete structure to form a structural reinforcement scheme similar to a "matryoshka". This new structure nests the old one. The load-bearing method of the structure ensures the safety and stability of the new and old structures, and also provides the greatest design freedom for reshaping the facade of the building.

一条黄色大楼梯

A big yellow staircase

另一个摆在业主面前的突出问题，是作为一个商业用途建筑，周边被密集的房屋包围，仅仅能从附近的广场瞥见建筑的一角，其余立面均被遮挡，难以被顾客发现识别。为了从这种围困中破局，我们将建筑的主楼梯从内部转移到建筑外部的转角处，朝向广场敞开，通过醒目的黄色建立简单、明确的视觉焦点.

在业主的功能规划中，建筑一层是家居饰品展示和咖啡吧，二层为工艺样板展示和洽谈间，三层为设计办公室，四层为会议室和合伙人办公室，四层功能是一个随着顾客交流逐渐递进的空间状态，因此同时我们将楼梯与各层的主要体验节点进行了一个整体流线的串联规划，一条黄色大楼梯在建筑的新老立面之间，内穿外出，形成独特的空间体验，也创造出不同角度的人与人、看与被看的互动关系。

Another prominent problem facing the owners is that as a commercial building surrounded by dense houses, only one corner of the building can be glimpsed from the nearby square, and the rest of the facade is blocked, making it difficult for customers to discover and identify. In order to break through this siege, we moved the main staircase of the building from the inside to the corner of the outside of the building, opening to the square, and establishing a simple and clear visual focus through the striking yellow.

In the functional planning of the owner, the first floor of the building is home decoration display and coffee bar, the second floor is the craft model display and negotiation room, the third floor is the design office, the fourth floor is the meeting room and partner office, and the fourth floor is a free With the gradual progress of customer communication, we have planned the staircase and the main experience nodes of each floor in a streamlined series. A large yellow staircase runs between the old and new facades of the building, passing inside and out. A unique spatial experience is formed, and interactions between people, seeing and being seen from different angles are also created.

绿意环绕，自然共生

Surrounded by greenery, natural symbiosis

建筑被周边密集房屋围绕的同时，也被几棵大树所环绕，树木与建筑的紧密关系，从设计之初就成为重要的考虑因素。我们希望在不同的高度，树木都能与建筑的内外空间发生积极的联系：员工可以在树下的空间讨论，享用咖啡；在二楼的休闲平台能触摸到树干的表面，感受树皮的肌理；在三楼的办公区靠近树的位置设置休闲区，午饭和茶歇的时候，可以通过长窗观察到树叶在微风中的细小颤动，从而感受到绿意环绕、微风习习的松弛感，以缓解设计工作的疲劳。每天上午温和的阳光会穿过树叶，将斑驳的树荫投入室内，树的姿态伴随微风的摇摆，在建筑立面上，形成一副无声的光影演出。

While the building is surrounded by dense houses, it is also surrounded by several big trees. The close relationship between trees and the building has become an important consideration from the very beginning of the design. We hope that at different heights, trees can have a positive connection with the interior and exterior spaces of the building: employees can discuss and enjoy coffee in the space under the tree; on the leisure platform on the second floor, they can touch the surface of the tree trunk and feel the texture of the bark ; The office area on the third floor is located close to the tree. During lunch and tea break, you can observe the small trembling of the leaves in the breeze through the long windows, so that you can feel the relaxation of the greenery and the breeze. Relieve the fatigue of design work. Every morning, the gentle sunlight will pass through the leaves and throw the mottled shade into the room. The posture of the tree is swayed by the breeze, forming a silent performance of light and shadow on the facade of the building.

Epilogue

在网红时代的网红城市，每一座商业建筑都被期待成为网红，同时也常常被非理性的视觉效果的要求所裹挟。如何在建立外观视觉的独特性的同时，不失去建筑学分析问题、解决问题的理性内核；如何使建筑能不止于在社交媒体上的视觉奇观，同时能更多的回归真实的空间体验，为来访的顾客和员工创造细腻、舒适的空间环境，是我们在本案中希望做出的一点简单讨论和思考。

In the Internet celebrity cities in the Internet celebrity era, every commercial building is expected to become an Internet celebrity, and at the same time, it is often engulfed by the requirements of irrational visual effects. How to establish the uniqueness of the exterior visual without losing the rational core of architectural analysis and problem solving; how to enable the building to be more than just a visual spectacle on social media, and to return more to the real space experience at the same time. Creating a delicate and comfortable space environment for visiting customers and employees is a simple discussion and thinking that we hope to make in this case.
