PARAMETRIC ASSEMBLY WALL AND CORNER

Figure 1 shows the initial exploration with no boundary conditions. The rule set is precise but simple, creating the desired hexagonal aggregation pattern. I then formed a planar wall by adding a rectangular mesh constraint to the aggregation.

The rule set allowed for the component to fill gaps in the straight edge to form perfectly orthogonal

This works well for closed corners; open corners are problematic because the front and collide when rear set faces perpendicular. have differently Floor and angled ceiling planes planesthatfit neatly into the chamfered edge when on module, but slip past and collide when not.

POROSITY COMPONENTS PHYSICAL FABRICATION

After creating each component in Rhino, I used the “Unroll” command to create foldable templates for each porosity component. I added tabs to each side of the beak for ease of gluing. Fold lines were scored on the laser cutter using a dashed line; I did need to score manually

to avoid crushing of the material at the crease. The first component, 0% porosity, folded and glued together easily.

The second, 40% porosity, was also fairly straight-forward, although I removed the interior tunnel and instead left only the tabs to shield the inside from view.

third component, 80% porosity, was the most difficult due to the thinness of each edge. The chipboard I chose to use was slightly too thick for such tight creases, and tended to bend or crush under the effort of pushing on it so hard. The tabs were also more difficult due to small margins of error.

If I were to create 3D components out of paneled sheet goods, I would be more selective when choosing a material. The double scoring technique was effective and the dashed edges add a certain diagrammatic feel, although it would be more distinct on

0% POROSITY THE BASE BEAK

The base component was not altered to create a different porosity level but instead was used as is to act as the most private block type. This block is also useful in shielding the interior from hot solar gain, especially important given the humid subtropical climate in Dallas.

40% POROSITY THE NESTING BEAK

The base component was altered to 40% porosity by extruding and applying a Boolean difference to the rear face. I then nested one into the next by aligning the corner points and applied another Boolean difference.

This allows them to fit together perfectly when 80% aligned.

POROSITY THE WIREFRAME IBEAK created the

most porous component by extruding the component’s silhouette when viewed head-on. I then offset it by 20% inward to create a smaller triangle. This was extruded through the original component and a Boolean difference command created a large hole in the

DISCRETE FABRICATION BLOCK PRINTING

Discrete fabrication has many advantages to on-site continuous printing, including controlled climate conditions and no site limitations.

Cementitious 3D prints currently struggle to run in low winter temperatures, thus limiting the construction period to fewer months of the year in many geographic areas.

The site must also be easily accessible and reasonably flat, as the printer rails require a flat bed and truck access in and out of the site.

Printing blocks in a predetermined factory environment negates these challenges, offering the ability to print constantly regardless of outdoor conditions.

Blocks are loaded onto trucks for transport to the site, but the site itself is not required to be flat. This minimizes the construction footprint on the land and its surrounding ecosystems.

If the site is unaccessible by semi- truck, construction can still procede as each block is

It is zoned R7.5A, the standard low- density residential zone for the city. There is a house directly across the street and one to the west; the north, east, and south boundaries are all uninhabited. The main access road

A walking trail runs along the eastern edge of the property line, creating a vegetated buffer between the lot and the adjacent cross street. The south end of the lot, although narrow, does have a view of the walking trail and green space behind the lot. I chose to divide the site into E-W bands of materiality and program, alternating between grass, plantings, paving, and

setbacks, I was only able to fit a one bedroom single-family residence and a small ADU in the backyard.

The two structures are aligned along the west setback, providing a circulation path along the west side.

The program is similarly organized along the N-S axis, with private spaces along the west, storage and service as a central buffer, and public space along the east

LUX PER DAY

The daylight availability according to Climate Studio was excellent, with 100% of the spaces daylit when possible. This is easy to achieve due to the space’s small size and regular shape. Notably, the analysis did warn against excessive glare during afternoon hours because I did not add any blinds to the simulation.

Due to the amount of windows, I will need to consider more shading than previously expected.

The average illuminance in both spaces on a daily basis is much too high without blinds, curtains, or other shading devices. It’s reading at around 2000 lux, when it should be comfortably within the range of 100-400 depending on the space or tasks required.

The only space that met this threshold was the kitchen in the ADU, since it was underneath the loft floor and was shaded from the skylights.

The radiation map shows optimal placements for solar arrays and the most effective locations for shading devices on the structure. The analysis shows that much of the building is shaded around the edges (most likely due to roof overhangs).
