Symbion Competition Study — Atelier Designa
Symbion Competition Study Competition / Early-stage design Symbion

From complex site constraints to clear design options.

Computational design modelling, early-stage environmental screening, and design studies for a competition proposal.

Atelier Designa supported the design team with rapid 3D studies, computational modelling, and quantified environmental screening to test architectural options and inform design direction.

The work helped translate complex site, programme, and topographic constraints into a more legible — and more measurable — design narrative.

Outcome
Faster iteration, quantified options, informed decisions

Faster options. Clearer decisions.

The project required quick testing of architectural ideas against site constraints, programme requirements, and visual identity.

Rather than producing a single static model, Atelier Designa developed a flexible digital workflow that allowed the team to explore massing, spatial relationships, façade expression, and presentation imagery in parallel.

This helped compress the design process and make each option easier to compare, discuss, and refine.

01
More options explored
Rapid digital modelling allowed multiple design directions to be tested without restarting the process each time.
02
Clearer design narrative
Visual material helped explain the project's relationship to site, landscape, movement, and architectural form.
03
Faster feedback loop
Ideas could be modelled, visualised, reviewed, and adjusted quickly.
04
Stronger presentation material
Images, diagrams, and studies helped communicate the proposal with more clarity and impact.

From rough intent to visual clarity.

01
Site and massing logic
The first stage focused on understanding site constraints, level changes, access conditions, and programme relationships. The aim was not to over-model the project, but to create enough structure for meaningful testing.
02
Environmental screening
The massing was screened against accreditation benchmarks — solar radiation, shading, and quality-of-view — to quantify environmental performance while the form was still open and could still be shaped.
03
Option testing
Multiple design options were explored through 3D modelling and computational workflows — testing scale, massing, façade direction, and spatial organisation against both site logic and measured performance.
04
Visualisation & presentation
AI-assisted visualisation accelerated visual development and communicated the proposal — turning tested options into competition-stage material that was easier to read, discuss, and present.

Quantifying performance before the design locks.

Alongside the design studies, Atelier Designa screened the competition massing against recognised accreditation benchmarks — LEED, BREEAM and BRE — using our in-house climate screening tool.

The screening was run at massing stage, while form and envelope were still open, and used to quantify the effect of a façade treatment option on the building's environmental performance.

The result was a measurable improvement — established before the design was committed, and before an accredited assessment would normally begin.

−48%
Mean solar radiation on the envelope, reduced from 526 to 275 kWh/m².
The façade treatment nearly halved solar exposure across the envelope — the primary cooling-load driver in this climate — while holding daylight, views, and outdoor amenity within target.
Solar radiation screening — base massing, no façade treatment
Base massing · mean 526 kWh/m²
The exposed envelope carries high solar load across the primary façades.
Solar radiation screening — with façade treatment
With façade treatment · mean 275 kWh/m²
The treatment shades the envelope, cutting mean radiation by nearly half.

Earlier than the sustainability consultant.

Environmental performance is usually optimised late — once form, orientation, and envelope are largely fixed. By then, the highest-leverage decisions have already passed.

By quantifying performance at massing stage, we don't replace the accredited assessment — we hand it a design that already performs, so the formal process starts from a stronger baseline.

Design-stage screening against accreditation benchmarks (LEED · BREEAM · BRE · Lawson) — indicative, not a certified compliance calculation. Screening is used to steer the design; formal credits are verified with the accredited assessment method.

Early decisions shape project risk.

Early-stage design decisions are expensive to change later.

For complex sites and competition projects, the risk is that teams commit too early to a form, image, or layout before understanding the consequences.

Atelier Designa helps architects test the logic behind the image — using computational modelling, quantified environmental screening, and rapid option development to make design decisions more visible, comparable, and controlled.
