What’s a Good Design Style for High End Hospitality?

There’s no single style that defines luxury hospitality, quiet luxury, biophilic design, Art Deco and Japandi can all work, or all fail. Here’s what actually makes a five-star space feel luxurious, memorable and true to place.

The $8,000 Barangaroo Apartment Lost to the $3,000 One. Neuroarchitecture Explains Why.

A regular person walked through Barangaroo’s most expensive apartments and chose the $3,000 one over the $8,000 one. Her nervous system processed every material choice and furniture decision before her conscious mind formed an opinion. Neuroarchitecture explains exactly what happened and what it costs developers who get this wrong.

What Makes Guests Sleep Better in a Hotel Room?

Four in five travellers have trouble sleeping in hotels. Peer-reviewed surveys agree on why: a noisy air conditioner, poor pillows and bedding, noise from outside, light and temperature.

What Is Biophilic Design in simple terms?

Biophilic design is not a style, a trend, or a shorthand for putting plants in rooms. It is an evidence-based approach to the built environment that takes seriously the idea that humans evolved in nature, and that our bodies and brains still expect it.

What Is Neuroarchitecture?

Neuroarchitecture is the application of neuroscience research to how buildings are designed. It asks a question that traditional architecture rarely does: what does this space do to the people inside it?

Is Biophilic Design Worth It for Hotels?

Yes, when it is built into the brief and delivered with quality rather than added as a living wall beside the check-in desk. What the peer-reviewed studies show about biophilic hotel design, willingness to pay and guest wellbeing, which segments it pays in, and which patterns matter most.
