WESEARCH LAB PLugin

WEsearch lab has released a free plugin which uses a custom defined generative algorithm to automate the placement of columns and beams on orthogonal plans to achieve regular ceiling division. The plugin controls the placement using three data input or variables –

The floor plan,
The minimum allowed span of slab, and
The maximum allowed span of slab.

The plugin, named Eelish, works on Grasshopper which is Rhino3D’s visual scripting platform. It can be downloaded for free HERE.

 

Architects typically invest a substantial amount of man-hours to determine the location of columns and beams on floor plans of framed structures. Subsequently, the fuzzy layouts are sent to the structural consultant for calculation of dimensions and specifications of columns, beams and slabs. Toolkits and software used to model column and beam layouts require explicit modelling from scratch without any automated suggestion of column and beam placement. The need of the hour is to develop an algorithm which takes conceptual CAD plans as input and automatically applies the inherent soft if-else logic of column and beam placement on the plans.

The objectives of the algorithm are twofold – i) to place columns and beams such that all the slabs are within predefined minimum and maximum allowed spans, and ii) to avoid irregular ceiling divisions in the interior. To study the manual process, ten architects were asked to place columns and beams on three orthogonal plans (convex, concave and a combination of convex and concave rooms) with three sets of minimum and maximum allowed spans of slab.

The empirical analysis of the layouts reveals that the symmetry of ceiling division of larger spaces takes precedence over the symmetry of ceiling division of smaller spaces. The analysis also reveals that concave rooms have least amount of irregular divisions at the periphery when column-beam grid of the largest convex space in the concave room is extended to the entire room.

Consequently, the algorithm of the plugin undertakes the sequential layout process from the largest to the smallest room. For all the rooms, the algorithm first calculates the optimised grid size of the convex room or the largest rectangle possible inside the concave room. For concave rooms, the grid is extended to the remaining portion of the room. For each step, new column placements are deleted if they are at a distance lesser than the minimum allowed span from column placements till the previous step (columns all rooms that are larger in area than the current room). Subsequently, in each step, beam centre lines are added as a function of the grid of the columns.

The column centre and beam centre line placement layouts generated by the plugin can act as starting baseline for manual local modifications. It is imperative that we automate such processes to emancipate architects from the uninventive repetition of generation and allow them to focus on exploration and evaluation of iterations.

TIGER TIGER – Nisha Mathew Ghosh

TIGER TIGER is part of a series on animals and their implied symbolic narrative appropriated politically and socially. This series studies the perception of people and conjures up new imaginaries as form is divested of its power by dematerializing it via the act of weaving a narrative shorn of the power, panache, swagger associated with the cultural, symbolic or naturalized form. – Nisha Mathew Ghosh

Conserving The Commissariat Building, DR DN Road, by Vikas Dilawari

Mumbai was the first city in India to have heritage regulations to protect its living heritage. This listing and the corresponding regulations binding these precincts would also protect these old areas from burdening the fragile infrastructure with high-rise buildings. These precincts, more than individual structures, puts forward each city’s uniqueness. Heritage awareness is certainly increasing on paper with more nominations of World Heritage Site ensembles. But in reality, its protection on the ground is decreasing at an alarming rate.

“A Sense of Space: This book is an invitation to liberate oneself from the valorised image of western or imperial city planning towards a more nuanced, indigenous, and flexible approach to our cities.” Sudipto Ghosh Reviews A Sense of Space, by Ranjit Sabikhi

Those wondering why the design of contemporary Indian cities is such an arduous and joyless affair will find Ranjit Sabikhi’s book of immense interest. Many may even find themselves jolted to action within their spheres of influence despite the book’s unflappable tone. Most importantly, this book is an invitation to liberate oneself from the valorised image of western or imperial city planning towards a more nuanced, indigenous, and flexible approach to our cities. – Sudipto Ghosh

Highway Restaurants Concept, at New Delhi, by Parag Singal Architects

The stirring proposal of Highway Bridge Restaurant was conceptualized by Parag Singal Architects. The idea is to build restaurants over National Highways that can be accessed from both sides of the road. Located on the center of the highway, it is almost impossible for the restaurant to go unnoticed by the motorists. It offers more visibility to the restaurant and makes it easier for the traveler to spot a place for refreshment, hence creating a win-win situation. – Parag Singal Architects

Located in Ayroor, Kerala this family home that sits on the banks of the Chalakudy river is nothing less than a mini-ecosystem within itself — self-sufficient and symbiotic. Using local masons, carpenters, contractors and construction methods, this home was completed with natural materials such as terracotta and laterite tiles, kota stone and terracotta jaali blocks. A generous verandah wraps around three sides and a large open terrace on the upper floor maximises the spectacular views out onto the river. The house is an extension of the clients’ (perfect) idea of living a retired life.
