Spatial idea
How clearly the selected works reveal a spatial proposition worth analysing.

GAD Study Index 2026: Ten Practices for Comparative Reading
A scored editorial selection of ten practices for comparative project study. Read the three dimensions, source-linked cases, ties and assessment limits.
Ten selected practices · study value, not worldwide design superiority · AI-assisted editorial pilot, no external jury · source check 2026-09-30. Method & limits
Comparative learning
How productively the cases support comparison across a shared design question.
Source clarity
How clearly linked primary records establish the facts and project credits.
Scores use 1 limited, 2 basic, 3 developed, 4 strong, 5 exceptional within this sample. Weighted score = Σ(score × weight ÷ 5). Ties share rank; name order within a tie does not imply preference. Small score differences should be read as nearby assessments, not measured differences in design quality.

Three museums make a strong comparison of daylight, the landscape edge and the movement between art and everyday experience. Chichu offers an especially clear counterpoint to the water and projecting roofs at Fort Worth.
Limit: The available records explain design intent more fully than long-term visitor experience or operational performance.
#2 / 93
Neri&Hu
Adaptive reuse, courtyard sequences and an art centre can be studied through thresholds and material memory. The architect’s project narratives make the comparison specific rather than stylistic.
Limit: Architect-authored sources establish the design proposition; they are not independent guest or community evaluations.
Structural tubes, continuous curved rooms and a field of arches make three different proposals for organising public activity. Owner and award-body records provide useful project context.
Limit: The programmes differ substantially, so direct efficiency comparisons would require additional data.
#4 / 87
Steven Holl Architects
The selection makes section and light productive ways to compare a museum extension, a contemporary art museum and a chapel. Different programmes help test which ideas transfer and which depend on a specific brief.
Limit: Light is discussed as an architectural proposition here, not as a verified photometric or conservation result.
A neighbourhood museum, a museum facing the city and a tall mixed-use building offer useful changes of scale. The source records support discussion of roof, edge and arrival while retaining project-specific credits.
Limit: The Menil record credits Piano & Fitzgerald; this historical connection is not a claim that the present practice alone authored every phase.
#5 / 86
WOHA
Hotels and a mixed civic-and-housing project make greenery, shared terraces and the vertical public realm comparable across briefs. The contrast between private hospitality and collective uses is particularly useful.
Limit: Visible planting does not establish measured carbon, maintenance, biodiversity or thermal outcomes.
Restoration, a new shared entrance and a riverside gallery expose different relationships between a cultural building and its setting. These are strong case studies for deciding when to connect, repair or distinguish.
Limit: The selection supports contextual reading, not a claim that one restoration philosophy fits every heritage site.
#7 / 80
Shigeru Ban Architects
Timber, screens and lightweight material systems give a useful route into discussing structure and public use. A cathedral and two art institutions invite questions about assembly and architectural expression.
Limit: A material’s name alone does not determine its lifecycle impact; comparable quantities and lifecycle boundaries are absent here.
#7 / 80
Studio Gang
The tower, museum addition and theatre offer three scales of interface between structure, enclosure and gathering. Their differences make the selection useful for design discussion without relying on a single signature form.
Limit: Architectural descriptions and imagery cannot establish occupant satisfaction or environmental performance.
#10 / 79
Mecanoo
Two libraries and a performance centre offer a legible reading of civic arrival, landscape and shared interior space. Official project records make the starting facts accessible.
Limit: The current sample is weighted toward large public buildings, so it offers a narrower comparison of the practice’s range.
