Parking House Facade
(Sketches)

 

    Project Phase: Study

As described on our [Algorithmic Design Workflow], this project is currently in the initial Study phase. The primary objective of this stage is to explore potential design directions and select the most viable concept. This chosen concept will then be further refined and developed from a preliminary idea into a comprehensive, final result.

   Ventilated Facades & Functionality
Designing facades for parking houses presents a unique challenge: balancing aesthetic appeal with strict technical requirements. Ventilated facades are essential in this context, as they must ensure sufficient natural airflow to dissipate exhaust fumes while effectively screening parked vehicles and interior lighting from the outside environment. The goal is to transform a purely utilitarian concrete volume into a visually engaging structure without compromising its permeability.

   Parametric Approach
To achieve this, we utilized parametric design tools (Grasshopper). This approach allows us to move beyond static repetition. By defining logic and rules—such as view angles, structural grids, or attractors—we can generate complex, responsive patterns. Parametric definitions allow for rapid iteration, enabling us to precisely control the openness of the facade at different heights and optimize material usage while creating a dynamic visual impact.

   Design Variants

  1. Gradient Perforation: A ventilated facade made of perforated metal sheets. Using an irregular pattern driven by data, the perforation is densest at eye level to maximize visibility and light, while fading to almost zero near the ceiling slabs to effectively conceal the concrete structure.

  2. Kinetic Hexagons: This concept features a grid of hexagonal panels controlled by guide curves. The panels tilt and extrude forward based on their proximity to the curve. The depth of the extrusion also drives a color gradient, adding a shifting 3D effect to the building envelope.

  3. Twisted Louvers: A facade composed of horizontal aluminum louvers bent within a single plane. The parametric manipulation creates a wave-like geometry, softening the rigid edges of the building and adding a sense of flow and movement.

KINETIC HEXAGONS

The Logic of Movement This study explores a modular facade system based on a uniform hexagonal tessellation. While every panel shares the exact same geometry, the façade creates a fluid, organic impression through parametric manipulation. The behavior of each module—specifically its tilt angle and forward extrusion—is driven by its proximity to invisible “attractor curves” drawn on the facade surface. To further emphasize the three-dimensional depth, we linked the extrusion parameter directly to a color gradient. As the panels step forward, they shift in color, creating a dynamic visual wave that ripples across the building envelope.

Infinite Configuration Potential The strength of this parametric definition lies in its adaptability. The images below demonstrate just a few possibilities using different color gradients and curve configurations, but the system is designed to be universal. The input logic can be easily swapped from manual curves to mathematical functions (such as sine waves) or noise algorithms for a more randomized texture. Furthermore, the transformation logic itself is interchangeable; instead of extrusion, the script could control aperture opening sizes via edge offsets to regulate transparency. The design is limited only by imagination and manufacturing capabilities, offering a vast range of aesthetic and functional outcomes from a single definition

TWISTED LOUVERS: FLOWING GEOMETRY

Elegant Interpolation This concept focuses on the elegance of continuous lines. The form is generated using a ‘tweening’ algorithm that mathematically interpolates geometry between two primary control curves—the top parapet and the bottom edge. By bending standard horizontal aluminum louvers within a single plane, we achieve a soft, wave-like articulation that disrupts the rigidity of the parking house box. We deliberately broke away from a strict rectangular footprint; the louvers gently overhang the glass facade of the ground floor at the corners, and the roofline rises and falls organically, giving the building a distinct silhouette that changes from every angle.

Adaptable Flow While this study showcases a clean, monochromatic look, the parametric setup allows for extensive customization. The complexity of the wave can be increased by adding more internal guide curves, creating tighter ripples or broader sweeps depending on the desired visual intensity. Furthermore, the system supports various color schemes, from subtle gradients to bold contrasts that highlight the movement of the geometry. This approach demonstrates how simple geometric rules can yield sophisticated results, with the final design evolution limited only by the client’s specific requirements and the project’s functional boundaries.

GRADIENT PERFORATION: OPTIMIZED TRANSPARENCY

Functional Gradients This study investigates a perforated metal facade where transparency is strictly controlled by function. Using a parametric Gaussian distribution logic, we manipulated the density of the pattern relative to the building’s height. The perforation reaches 100% density at eye level to maximize natural light and outward views, while smoothly fading to zero (solid metal) near the floor and ceiling slabs to effectively conceal the internal concrete structure. While this iteration shows a consistent vertical gradient along the entire perimeter, the script allows for localized variations, enabling us to easily adjust the pattern based on specific curves or distinct façade segments.

Efficiency Through Information The true strength of this design lies in its manufacturing efficiency. Unlike complex gradients that rely on varying hole diameters—which complicate production—this system uses a single punch size on a fixed grid. The design is defined purely by information: a binary instruction of whether to punch or skip a position. This makes fabrication significantly faster and more cost-effective. Due to the massive quantity of holes (tens of thousands), we utilized alpha-channel bitmaps for efficient visualization. For production, this “image” data is seamlessly converted into coordinate tables (CSV) or simplified DXF files, ready for direct input into CNC machinery.

REALISATION (Technical Data & Fabrication) — How do we build it? (Hand-in data)
In the final phase, the project becomes production-ready. I generate clean 2D outputs (DXF/DWG) for CNC milling or laser cutting, and I can automate part tagging so every unique component is numbered for smooth assembly. I deliver accurate data tables and a bill of materials (BOM), including dimensions and quantities, and—when needed—structural information such as weight, volume, or center of gravity. To support efficient fabrication, I prepare nesting strategies to reduce material waste, design construction details (support systems, backings, brackets), and incorporate real-world constraints like tolerances and assembly logic. If required, the output can also be prepared for BIM workflows.
