50 Housing Floor Plans 2 / a+t research group

Taking form as a compact deck of double-sided cards, with the numbering of the cards corresponding to the size of the floor plan area, from smallest to largest, this useful guide offers detailed technical information together with criteria for estimated privacy and exterior quality. A wide spectrum of shapes is made available, and both vertical and horizontal circulation indexes are given with each floor plan example. Adding to the collection’s accessibility, measurements are expressed in both metric and imperial units.

50 Housing Floor Plans 2 is the fourth deck in the a+t research group’s card collection, created to promote the compact city and highlight exemplary contemporary housing.
It brings together 50 floor plans from notable collective housing buildings (2015–2025), representing a wide range of urban conditions, along with 50 units extracted from those same plans.

The a+t research group evaluates every project through two key parameters that shape desirable housing: Privacy and Exteriority.

On the front of each card, a plan drawn at 1:1000 or 1:1500 scale shows the estimated level of Privacy based on:

• vertical circulation cores
• horizontal circulation area
• actual building heights
• number of dwellings per floor

On the back, a unit drawn at 1:300 scale illustrates its level of Exteriority according to:

• proportion of outdoor space
• proportion of façade
• number of orientations
• window widths
• depth of the dwelling

Units are presented in both metric and imperial systems.
The card-deck format (13×8 cm / 5×3 in) allows quick comparison and helps identify the strengths of each plan and each unit at a glance.
