Bartlett School of Architecture at UCL has been running an architecture workshop for people with visual impairments

Visualise yourself entering a new building. What do you notice first?

The answer for most people will probably be the internal structure, the colour of the walls, the light entering through the windows. But stay a little longer and you might start to experience the space differently: you’ll hear sound reverberating, you’ll feel air currents, textures and materials, you’ll smell wafts from the kitchen.
