House City-Wall
by Nodo17 group


House City-Wall is located in the heart of the historic center of Seville. Its facade forms part of the third walled enclosure of Real Alcázar of Seville, constructed between eleven and twelve century. So many are the centuries of this house as the modifications that have been done over time. Our design will be just one more within this long chain.
I does not pretend to be the last one, but just a catalyst to allow continuity and future evolution. A detailed research has allowed to identify the origin of these transformations. There are many different types, from upper expansion, sale and division of part of the house, new openings in the city-wall, reconfiguration of the patio structure, use change, etc.

Against this background we have not privileged any moment over another. We have tried just to add value to a long evolutionary process. Central patio is the architectural element that best shows the traces of time evolution. Stone pillars alternate with load bearing walls, openings of different sizes and shapes show the expansions realized, as well as the traces of the perimeter galleries.





Walls around patio has lost their thickness and their clearly defined limits. They are replaced by metallic structures that reinterpret and give continuity to existing stone pillars. In contrast, current openings and balconies acquire thickness and refer to their original position and shape.
The patio acts as a valve of climate and life. Everything happens around it. A “montera” closes its upper level in order to allow its opening and closure according to exterior and interior climate conditions. The galleries are the soul of the house where relationships are enhanced and arise not only horizontally but also vertically and diagonally.

nodo17 group is a Madrid based office of architects, urban designers and ecologists operating within the fields of urbanism, landscape, architecture, engineering and ecology. We define our approach as evolutionary urban design by which we understand the design of self-organized environments through technological relationship between nature and society. We have applied these strategies to design in projects in Bosnia-Herzegovina, Spain, Sudan and Canada.
nodo17 group was founded in 2001 by Manuel Pérez Romero who has been the director since then.
In 2013 Jaime Tarazona Lizarraga became its first partner. nodo17 has received more than 15 awards in national and international architecture design competitions and their work has been published in more than 100 magazines and books. Recently, the Korean editorial Damdi Publishing Co. has published a monographic book about nodo17 work.
nodo17 has a R&D+i department for the research of new construction systems and processes, for which nodo17 has already three registered patents. Recently nodo17 has founded the company HDa (High Definition Architecture) based on 3D printers technology. HDa fabricates, design and construct its own products.
