How do you speak to a new house? You walk in, look around and then say something out aloud, hearing your voice come back to you several times over as the sound bounces off its empty contours.

This week, the echo calls for us to listen—because what comes back might be altered, softened, amplified—carrying experience, memory and perhaps even uncertainty. At the Poole Museum in Dorset, ZMMA's restoration and redesign transforms a regional museum into a lively cultural venue, resounding with the energies of the people who are expected to occupy it. In the face of disappearing 'third spaces', places that feed into our shared well-being, Cristina Mateo proposes a 'fourth space', an immersive environment that is fuelled by technology as well as

spatial design to centre participation, mutuality and belonging. In New Delhi, India Art Fair returns with its biggest edition yet, with local and international art and collectible design—a buoyant art market in the wake of global economic challenges. And in Mumbai, Pinakin Patel echoes learnings from decades of practice in selected works from his collection and the Dashrath Patel Archive at Mumbai's Nilaya Anthology.

The echo is a unique product of material and animal encounters, produced when soundwaves travel across space, arrested in transit by a solid surface, to be reflected back at you. A mirror—for sound.
