Córdoba的城市中心是由密集的街区以及街区围合出的天井内院组成的，这些内院的空间特征从未被深入研究过，也因此为该地区附上了一层颇具神秘感的面纱。当人们进入内院时，会神奇地发现不同时代的建筑痕迹，在这里，充足的室外空间为室内提供了良好的通风与采光，同时保证了使用者的隐私。空间虚与实的对比创造出光与影的游戏，进一步增强了地中海式建筑的历史韵味。小巷、过道、走廊、庭院、画廊、日光浴室以及屋顶上碎片化的景观空间，共同构成了散落在密集城市中的空间网络，形成连续的街区内公共空间系统。

The urban center of Córdoba is made up of dense blocks drilled by infinity of patios that give to this place the character of a space never fully known. When we go inside we find an amalgam of constructions from different eras where mass and emptiness alternate giving light, air and privacy to the inside. This territory of light and shadow is articulated throughout the collection of intermediate spaces that nourish the Mediterranean architectural heritage. Alleyways, open hallways, passages, corridors, courtyards, galleries, solariums and, finally, the fragmented landscape of the rooftops, make up a network of empty spaces that are interspersed in urban density providing continuity to the public space inside the block.

在此背景下，Sol89事务所与三位业主合作，利用住宅扩建出一所街区内院中的办公室。办公室共有三个部分，其中两部分位于一楼，另一部分位于顶楼。扩建的核心理念旨在使不同区域之间衔接自然，从而保证空间的凝聚力，营造出良好的工作与合作氛围。建筑师经过不断推演，最终定义出一个连续的空间，空间流线由原有的办公室开始，穿过街区内部进入庭院，继而与高密度的建筑群融为一体，办公室的体量时而凹陷，时而出挑到庭院中，最终直达另一侧楼群的屋顶。

In this context, we have to project the expansion of an office located in a three-dwelling house plants by the incorporation of three new properties, two on the ground floor and one on the top floor. We believe the extension should happen without perceiving the transit between one area and another, thus guaranteeing the final cohesion of the resulting workspace. We propose the intervention trying to draw without raising the paper pencil, defining a continuous space that from the original offices penetrates through the inside the block, going through courtyards, entering the built density, hollowing out when it is demanded and peering into the existing courtyards until reaching the rooftop.

地板、天花板以及外立面在整个扩建过程中都得到了延长，以强调出空间的连续性。内部设有加热系统的混凝土材质地板被抬高，由室内延伸至室外，模糊了内外部空间的界限；原有的混凝土天花板结构之间插入了木条拼接的隔音板，这种设置为室内增添了全新的表现力。

Floor, ceiling and cladding exterior are prolonged throughout the intervention to underline this continuous condition of the space. A elevated and heating concrete floor crosses interior and exterior spaces; the roof is solved with an acoustic panel of wooden slats inserted between the original concrete structure that acquires a new expressiveness when framed by it.
