Neural Network or other M.L applications are so integrated into our daily life, that we hardly notice it. These technologies focus on automating the work we do manually, so that we can shift our focus towards more sensible and stimulating subjects. This is the same in Architecture where there is a lot of work done in using machine learning techniques to deal with more basic tasks while the designer get more time for creative expression. And thus enabling us to use our brain’s capabilities to intuitively express designs and 3d forms as well as expand on it .. And this lead us the question of

How can we recreate this capability of creative expansion using A.I/Machine Learning?

Project Workflow

The project followed a workflow involving curation and preparing 3d datasets, data conversions, and many iterations of training. Multiple models where tested out with different runs for each with varying hyper parameters until the best combination is achieved.

The aim of this paper is : To explore the potential of 3DGAN NNs in architectural design as an efficient method in generating new design solutions. To unveil the possible use of latent space operations as a design methodology. To identify the directions in which this methodology can be taken forward as new creative design tool.

After success with the resolution of 323 we decided to further develop tensorflow 1 architecture by increasing the resolution to 643 and training the model further. [model 4, res: 643]

The outputs of the last test were satisfactory on various different datasets and thus we performed interpolation.

In order to get most meaningful results we tested variety of different tools including vector interpolation, vector arithmetics, learning from checkpoints and transfer learning.

MaCAD | Architectural Intermediates

Run I 3DGAN

The first run involved a keras implementation of the architecture suggested in the MIT paper[5]. This model was ran on two different dataset : IKEA furniture dataset and a column capital dataset.

IKEA Dataset

Column Dataset

With the use of matplotlib libraries in python we were able to visualize the output based on the values predicted, thus giving a deeper understanding of the performance of the model and the output generations. The model architecture had 6 hidden layers for the generator and 7 layers for the generator. A binary loss function is used to calculate loss values . The learning rates used where from the reference paper.The outputs were not refined but the model was still able to generate capitals and tables that were distinguishable.

Neural network architecture

Column dataset 0-5000 epochs

IKEA dataset 0-5000 epochs

MaCAD | Architectural Intermediates

The generated outputs showed very low variations and tend to generate almost similar output geometries. This showed signs of mode collapse .

3DIWGAN

“Mode collapse occurs when the generator produces an especially plausible output, the generator may learn to produce only that output. In fact, the generator is always trying to find the one output that seems most plausible to the discriminator.”

“Wasserstein GAN, or WGAN, is a type of generative adversarial network that minimizes an approximation of the Earth-Mover’s distance (EM). It leads to more stable training than original GANs with less evidence of mode collapse.” With the use of the Wasserstein method the GAN model can be optimized so that the output generations have variations. The model trains to optimize the weights so that it deviates from generating single solutions. This provided a perfect solution to the issue of mode collapse.

Improved 3D IWGAN

An update to the 3D IWGAN was done to accommodate and improved dataset of resolution 64 x 64 x 64. This meant adding additional hidden layers at the output of the generator and the input of the discriminator to reshape the generated sample. For this a new dataset of churches in the higher resolution of 64 x 64 x 64 was made .

Voxelized [32, [64, 32, 64, 64] 32]

Church model voxelized with higher resolution for improved N.NW

The first run with this model was done with the same parameters as of the 3DGAN[5] paper and as expected the model had the tendency to leave out finer details. This might be due to the fact that the parameters used in the paper were optimal for generating furniture and other objects with larger and more distinguishable details. This meant the model required more fine tuning through trial and error until an ideal region is identified with the parameters. By increasing the learning rates, we observed that the model started learning more and outputs more detailed but at higher epochs the loss values started to climb up and the GAN model became unstable again. After a number of iterations an optimal range was reached within which the model kept improving with more training. The loss values kept reducing and the outputs showed more positive results. With this the process was continued on an extended dataset and 11 rotations per each geometry in the input dataset is introduced. The new generations showed more variations with more mix of features

For the latent space operations to be more appropriate it was one of the priorities to be able to map the inputs in the latent space. This could enable us to develop a method to input 3d geometry and do latent vector operations on it. Many papers such as the embedGAN[8] addresses this issue and the solution is to further optimize the random latent input vector to reduce the distance between the inputs and the generations. With this approach we ran further iterations and were able to generate geometries with features almost identical to that of the input dataset. Here on the figure to the left we can see the generations similar to the dataset and as you move further to the right more features and unique solutions can be observed.

Generations with inputs embedded in the Latent Space

Latent Space Interpolation Interpolation between selected geometry generations

Latent space representation

This enabled for a latent space interpolation between inputs as well as new generations. A latent space can be imagined as a 3D space which represents a distribution on to which the generations are mapped. Two points in this distribution represents two generations and a path between the two will mark the transition between two geometries. By moving through this path we can generate all geometries between these two points. A spherical linear interpolation is showcased on the right between the selected generations. This is exciting as this method , with sufficient data offers a possibility to find the intermediated between any two geometry which have completely different shape, size and topology.

Use Case I

Interpolations using ZHA designed buildings

Central Bank of Iran Baghdad

Galaxy SOHO Beijing

Riverside museum Glasgow

Wohanhaus C Vienna

Z.H.A models voxelized in 64x64x64 resolution as inputs

As the last step of the explorations the approach followed was to identify a small test dataset of architectural data. We chose buildings designed by ZHA in this case and prepared a dataset of recreated models from sketchup warehouse and used it to embed into latent space to perform interpolations.

Riverside museum Glasgow

Galaxy SOHO Beijing

Phaeno Science Center

Interpolation between selected ZHA models

Though the outputs of the interpolations were very crude this still showed signs of promise. We could observe some intermediates between different buildings in the latent spacewalk. Considering the fact that we used 8 models that are very distinct, we are sure that with higher resolution with a large enough dataset like what is available for any architectural practice this method has great value and potential.

MaCAD | Architectural Intermediates

Combined Workflow

Further steps involving 2d-3d reconstruction and Decor-GAN

The combined workflow will enable new opportunities in the field of design. The reconstruction phase can be altered to input any data that can be embedded in a 2d image format and this will enable us to create generations in a more controlled manner. Thus creating a tool with which the architect or the designer has the role of initiating the creation but with the neural network will be able to generate solution much beyond what they can create themselves. Further improvements in the direction of 3d generative neural networks can thus open up new expanse in the field of design.

Image taken from paper.

An extension of this can be a 2D- 3D reconstruction as in the mentioned paper. This method uses paired dataset like a 2D DCGAN and therefore can be made into a 3DCGAN, which has high application in the field of design..

Decor GAN could be another extension where the low resolution outputs can be up-sampled into higher resolution. This also offers the possibility to tune the upscale and meshing based on the dataset the Decor GAN is trained on and there by opens the door to style transfer and similar methods.

MaCAD | moonscape Lunar Meditation Temple B.I.M.S.C studio project | Tutors: David Andres Leone, Oana Taut Moon(e)scape is an exploration into envisioning the idea of worship, spirituality and common identity far from where we identify ourselves to be in, in an off world environment. The project is located at the south pole of the moon, specifically along the rims of the Shackleton creator. The temple caters to the residents of the lunar colony.

The project is aimed at creating a universal space that would invoke a sense of collective consciousness while understanding the relationship between the individualistic identity and the coalition of every individual identity into a single collective superpower. The recurrence of SACRED GEOMETRY & NATURE, in various religions, cultures and primitive beliefs will be the driving force of form organization. While ADVANCED TECHNOLOGY and SUSTAINABLE METHODS OF CONSTRUCTION, will aid to create a space that can contribute to a sustained and a healthy community.

The design development laid its foundation on 4 agendas that we established, allowing moon-lings to isolate within themselves completely while invoking a journey of growth, connecting different programs, people and unifying them into one. A central focus that transitions the inside and outside,respecting the diversity of each individual part, converging the variables into one single form.

Learning from moon based projects we separate our construction process into the exterior and interior spaces. Basalt with PLA being a non porous airtight material made it ideal for enclosed spaces and lunar Regolith being porous made it ideal for the external shielding

The silhouette of this form is divided into 2 portions; the external and the internal temple. Symbolizing the external material world and the world that lies within oneself. This approach has allowed us to split the form into multiple layers, shielding the interior spaces from the harsh radiation. The underground LNS connection marks a safe entry point into the structure, creating communal spaces for meeting. With a level dedicated solely to religious worship rituals and isolated meditation pods, followed by a completely silent group meditation chamber.

Within the interiors of the temple the areas are subdivided in 4 main levels, creating a spectrum between communal and silent zones

Level 0 consists of the entrance docks, and the supporting service spaces. Followed by Level 1 having 3 different kinds of flexible worship+prayer rooms along with individual cells for isolated meditation on the periphery. Level 2 contains the completely silent group meditation chamber, in form of a stepped well. The exterior portion of the temple has an alternate access from the outside that connects to the topmost view point.

From the conceptual explorations, we are left with the structure that rises from the terrain and merges into one. We have several approaches for formalizing this, where we had a concave tower rising up, and then a more convex shape, which we found might be more suitable for the 3d printing construction technique but deviate from the initial conceptual form. Finally we decided to have a multi-layered approach with a combination of concave and convex geometries, keeping in mind the construction methods.

The multilayer approach gave us a way top introduce openings into the 3.D printed structure, and also have a control over it. Bringing in sunlight for the exterior temple was a key factor of the form deriving process. The openings were controlled and ran the evolutionary solvers to optimize light. Sun vectors are calculated for the lunar south pole, and ran a sunlight analysis and the form/openings are optimized based on this. Since the sunlight is mostly horizontal, the analysis surface was divided vertically and based on the sunlight requirement each area was optimized.

We have split up the form and the workflow into 8 different streams, amongst 4 contributors. These streams divide the form into the exterior and interior portions.

With the 3d printing fabrication in mind, as mentioned, we have build an exterior shell based on a convex and concave forms. By doing it we intend to create a balanced between shells that allows a wider convex base as well as we densify the shell structure to increase shielding and lower down radiation.

New York City, which is a data rich geo-location was chosen for the first implementation of the Urban Path Maker tool. The availability of this dataset is a crucial part of choosing New York City as our case study. To create a pedestrian simulation tool based on machine learning models, it is important to have reliable data to train these models on to get the best and most unbiased results. We also would like to highlight the importance of the work that the Department of Transit in New York has done in collecting these data as this dataset has allowed us to study and create this tool. The Urban Path Maker tool can be replicated in any other city that has a similar pedestrian dataset.

Having evaluated our limitations, we figured that our opportunity lied in trying to bridge the gap between webscraped information, results of computed agent simulators, and pre-developed physics based simulators that use flock functions for multiple agent interaction. This meant that we would collect our second-hand augmented dataset and place it in yet another black box, the pre-computed flock. Unity offered the possibility of integrating all of our data, visualizing our pedestrians, and furthermore publishing our tool as a gamified platform that becomes accessible to non expert users.

MaCAD | Illu-ML: Predicting Sunlight with M.L Location: Moscow Seminar excersice | A.I.A semester] | Design Guide: Garbriella Rossi Create a tool to classify the windows in the apartment block according to the duration of their exposure to direct sunlight.

Case study: multistory apartment building 8 cores | 70X100 m perimeter | 46X76 m courtyard |Facade grid 3X3 m Sun path setup: Moscow, Russia | Date : equinox, 20.03.

For this exercise decided to create a tool to classify the windows in the apartment block according to the duration of their exposure to direct sunlight. For the case study we have built a simplified model of a multistory apartment building with 8 cores, arranged into a rectangular urban block 70X100 meters. Its courtyard would inevitably have some dark corners.

Simulated window performance based on amount of sunlight received calculated using Ladybug

We have set up a simple rectangular grid for the facades – 3 by 3 meters, assuming that would the realistic room front, and set up the sun path for Moscow, Russia, for the date of the spring equinox. Grasshopper is already solving the task of sorting the windows with sufficient and insufficient insulation but the reason to learn how to do this task by the means of machine learning is that it may be required to do quickly in much bigger scales for the large masterplanning projects, when simulation may become require too much computation capacity.

For this set of exploration, all interior windows are considered and five more categories are introduced for the sunlight received by the windows. Thus enabling a broader perspective of the window performances.

The P.C.A analysis on the dataset shows a close relation between the features chosen for the machine learning model. The Y position of the windows have more impact on the prediction results, followed by the height of the building cores oriented to the north due to the chosen location. The analysis shows the features chosen are valid.

Site Location in Mumbai east coast

The site is mostly barren and left undeveloped. The site is unsuitable currently because of the high noise levels even though it is green. The noise is mostly due to the construction activity that happens around the site and due to the ship breaking yard nearby.

Primary constraints for site interventions

The proposed programs for the site are a public retail area with landscaped paths at the site level and a commercial office space for the rest of the building.

Aggregation Logic

Using WASP Components in Grasshopper

Developing interlocking modular approach

Modular entities have objects which repeat with respect to each other. Cells Modularity can also lead to sustainability as the form-work used to build one module can be repeated to build the other modules hence saving material, money, as well as time. Modularity can allow for phase wise construction which can help in incremental building. The programmatic requirements for a coworking space in general are studied in order to be incorporated in the proposal. Public spaces like the library, cafeteria.

The optimization was ran for a population of 10000 individuals along 5 generations. Out of these iterations three were chosen as the final selections based on a balanced result values for each criteria. From this a best performing option was selected.

Selected Individual

The next step was to create a more balanced and stable structure by using the base units. So an approach of symmetry and repetition can bring in more stability as the interconnections increase. Based on structural analysis, an optimal orientation of structures was found.

Best performing individuals based on the Fitness cafeteria’s

This interconnected from is then optimized further based on stability and volume. and the final set of iteration was derived from which the best performing individual would become the final design form.

These forms integrated landscape features into it creating an optimized output that functions well with the surroundings and activities The final best performing solution is selected considering aesthetic and functional qualities as well.

Fabrication Steps

Based on the study models a truss assembly approach for fabrication was adopted. The individual timber strips extracted from the final form is bend individually in a bending form-work and these bend timber strips are connected in pairs using steel brackets. These paired timber strips forms a truss and this is then assembled together. For this approach form work for bending each timber strip is extracted and the angles and position of each member of the form work is extracted from grasshopper.

Stages of Pro-typing to study fabrication possibilities

This framed form which created the ruled surface was studied based on the possibility of bending strips in place and assembling them together. But the initial model informed us that the framed system itself hinders the process of interconnection of the timber strips.

Academic | Cultural Center Location: Vellayanni, Thiruvananthapuram Individual project | Semester 5 [2014] | Design Guide: Prof. Niranjan C Warrier

The cultural center acts as a common platform for different performance artists to meet and hold performances, talks and discussions. Vellayanni being a very cultural rich part of the city is usually a venue for performance arts from around the country. The aim is to create a perfect space of balance for different artists to collaborate and offer a common ground for the art enthusiast sharing interest.

The site has a very interesting and contrasting context on either sides of the river bank. On one side, is the lush green forest with waterfall and rock formations which extend into the site. On the other side, is a disturbed terrain. This contrast is structurally made clear creating two separate zone through the stair structure with walls., Thereby emphasizing on deforestation,sustainability, ecological balance while creating awareness about environmental impacts

Zone I: Context- Disturbed Terrain Site Intervention - Maximum Protection of Natural Landscape

Zone II Context- Ecologically rich terrain Site Intervention - Concrete structure blending into the rocks Concept Sketch

Academic | De Mello’s Residence Location: Kodungaloor, Individual project | Semester 4 [2013] | Design Guide: Prof. Soumini Raja The proposed project is a summer residence for an artist and sculptor. The site is a piece of land snuck beautifully between the banks of an estuary and the foot of rocky mountains.

The studio is made to look like its floating in the pool on one side and the rock formation is brought inside making it almost seem like the space is sculpted out of the rocks by the bank.

Schematic Plan

Academic | De Mello’s Residence

Sculpting is usually done in one of the two ways - additive and subtractive. Majority of the structure is made from poured concrete and Natural stone both of which are done following processes similar to additive and subtractive sculpting.

Professional | House No. 3 Location: Thiruvananthapuram | Area: 3200 sq ft Lead Architect and Designer | Renovation - Exterior & Interior | Under Construction The main aim of the project is renovation of a 30 year old house to a completely new look and feel. Minimal demolition and limited cutting of openings in the wall were critical constraints. Alteration to the structure was limited to only the components that would increase the overall structural integrity.

Planning is done so that the new structure merges cohesively with the existing, creating a sense of balance between the two.

Living room is expanded by moving stairs outside, creating a free and modern front facade. The use of textures on the facade gives a more contemporary feel to the overall form and structure.

Professional | House No. 3

The interior design is done keeping the structural details in mind such that the interior and exterior form parts of the whole instead of separate entities.

Interior design - master-bedroom

Play of wood, concrete and metal - materials identity is translated into design

Professional | Dandeli Cottages Location: Dandeli | Area: 550 sq ft per cottage Lead Architect and Designer | Renovation - Exterior & Interior | Under Construction The site is located right next to a reserved forest with rich vegetation all around and a river flowing by the side. The brief was to design cottages for an existing home stay resort. Since the site is ecologically very rich and the river is the main source of water for various wild animals, it makes an ideal destination for nature and wildlife enthusiasts.
