Generating Variations on SANAAs Moriyama House with Rhino Python – Generative design working with logic from the Moriyama House

Moriyama House Info

The Moriyama House is a series of connected apartments located in Toyko, Japan designed by Ryue Nishizawa of SANAA. These buildings are placed on a lot with each mass containing a different part of the overall program. Together all of the masses combine to equal an entire home, but each piece varies in size and shape based on program housed inside. Some are as small as space for a single shower, and others are multi-stored and feature spaces for a kitchen, living spaces, and a bedroom.

In my program, I sought to capture the iconic image of this project; the simple white volumes arranged on a site with irregularly spaced fenestration. This was achieved by researching some of the drawings and design process of SANAA in order to create the most accurate means of recreating the site.

Exercise 5 – Making Dimensions Parametric and Windows Spatially Relevant

This assignment is the capstone for the course and focused in large part on resolving some of the issues of the previous iterations. The first step for refining my program to make it closer to the actual Moriyama House design was to divide the building masses into figurative ‘floors’ to allow for the creation of windows on both ‘floors’. This not only refined the dimensions of windows but also make the buildings seems more human scaled and architecturally believable. The next step was to make the windows proportional to the surface they are being placed on. Through this step they went from being generated from a fixed range of dimensions to one directly derived from the placement surface. This is continued as the window is shifted by an amount relating directly to the dimension of the placement surface. Ultimately these changes have resulted in a significantly more believable building.

Exercise 4 – Adding Dimension and Recording Information

The fourth assignment focused on the addition of dimension to the extant building surfaces and refining the window placement program. The windows that were previously placed in the center and generated directionally from that point are now placed on the surface in the center and shifted from this location. Additionally the windows are now extruded and placed into the wall surfaces.

Exercise 3 – Defining the 3D Form of Buildings on the Site

The third code of the project featured the consideration of the form in three dimensions. Each building footprint established in the first in extruded by a generated amount and then capped into a solid object. From this point a function is evoked that generates windows on surfaces as selected by the user. Once a surface is selected, the rectangle is placed in the center of the surface and shifted by a generated amount. This process continues until the user indicates there are no more windows to be placed.

Exercise 2 – 2 Dimensional Development of Plots and Building Footprint

This assignment began my selected topic of generating a program that produced iterations that emulate the massing of the Moriyama House as designed by SANAA. For the second exercise this involved analyzing the rules that governed the arrangement of the buildings on the plot. The first realization was that the buildings fit nearly into a grid that is overlaid onto the site. From this point a centroid of each plot could be shifted and from that centerpoint, a building footprint could be generated in two dimensions.

import rhinoscriptsyntax as rs
import math as m
import random as r

rs.DeleteObjects(rs.AllObjects())

lotSizeX = 240
lotSizeY = 120

zoneSizeX = 60
zoneSizeY = 60

nrZonesX = lotSizeX // zoneSizeX
nrZonesY = lotSizeY // zoneSizeY

#add frame
plane = rs.WorldXYPlane()
frame = rs.AddRectangle(plane, lotSizeX, lotSizeY);

#definitne the make windows tool by llocating the origin of the rame, then the centerpoint
#then moving the plane by a random amount for variation, and generating a rectange of a randomized height and width
def makeWindow (frame):
    origin = rs.CurveStartPoint(frame)
    midPoint = [origin[0] + zoneSizeX / 2, origin[1] + zoneSizeY / 2, 0]
    center = rs.AddPoint(midPoint)
    planeTwo = rs.MovePlane( plane,  midPoint)
    windowNew = rs.AddRectangle(planeTwo,r.uniform(20,50),r.uniform(20,50))
    rs.MoveObject(windowNew,[r.uniform(-20,0),r.uniform(-20,0),0])

#the make window command is applied for all of the 'zones' created in the project, based off of the lot and then sone sizes
for j in range (0, nrZonesY):
    
    for i in range(0, nrZonesX):
        newPlane = rs.MovePlane(plane, [i*zoneSizeX,j*zoneSizeY,0])
        rs.MovePlane( plane,  [r.uniform(0,30),r.uniform(0,30),0])
        zone = rs.AddRectangle(newPlane, zoneSizeX, zoneSizeY)
        makeWindow (zone)

Exercise 1 – Exploring Abilities of Python for Rhino

The focus of this assignment was to explore the constraints and rules relating to the basic operating of Python in conjunction to Rhino. The outcome was a fixed product drawing mostly on the in-program commands from Rhino evoked by name in Python. In this exercise these skills were used to generate a two dimensional image of a character from a cartoon.

rs.AddCircle([12,3,0], 1.5)
rs.AddPolyline(([11,6,0], [8,6,0], [9.5,8.5,0], [11,6,0]))

#Adding oval buttons on bottom
rs.Command("Rectangle Rounded 1,2,0 3.5,3,0 0.5")
rs.Command("Rectangle Rounded 4,2,0 6.5,3,0 0.5")

#Oval button at top
