Nervous System Design™ is a way of designing buildings, interiors and objects around how the human nervous system actually responds to a space: to light, air, sound, temperature, touch, routine and the presence of other people. It was created by Amanda Talbot at Studio Snoop.

Most design starts with how a room looks and how it is used. Nervous System Design starts one step earlier, with how the people inside it sleep, recover, focus and feel, and then shapes light, air, acoustics, materials and layout to support that. It draws on neuroscience, sleep and circadian research, environmental psychology and two decades of designing homes, hospitality and wellness spaces.

A conventional brief lists rooms, sizes and style. A biological brief adds the people: how each person in a household or organisation sleeps, recovers, works, connects and feels, including neurodivergence, hormonal change, burnout, ageing or chronic stress. It turns that into clear design requirements for light, air, sound, temperature, privacy and layout.

You do not need one to build a house. But if anyone in the household is struggling with sleep, stress, sensory load or recovery, a biological brief gives your architect and designer something they rarely receive: a measured picture of the bodies they are designing for, before the floor plan is fixed. Studio Snoop writes these as The Biological Brief.

Every person is different, so start by noticing what overwhelms them and what calms them. Common patterns are sensitivity to noise, bright or flickering light, strong smells, clutter and unpredictable change, alongside a need for movement, routine and somewhere to retreat.

Useful moves include: a quiet retreat space that belongs to them; soft, dimmable, flicker-free light; good acoustic absorption in busy rooms; clear zones for activity and for rest; storage that removes visual noise; and predictable routes and routines through the home. Involve the person themselves in the choices wherever possible.

Darkness, cool air, quiet and a predictable evening rhythm. Light is the strongest signal to the body clock: bright daylight in the morning, dim warm light in the evening and real darkness at night. Researchers recommend melanopic light of at least 250 lux by day, no more than 10 in the evening and no more than 1 in the sleeping room at night (Brown et al., 2022).

A cooler room helps the body’s temperature fall before sleep, and a warm bath 1–2 hours before bed can help you fall asleep faster (Haghayegh et al., 2019). Blackout, a bed placed away from noise, materials that soften sound and lamps rather than overhead light in the evening all make a measurable difference.

It can make recovery easier or harder. We spend around 90% of our lives indoors (US EPA), so the building is where most of our recovery happens. Spaces that give daylight, views of nature, fresh air, quiet and somewhere to step away from other people support the body’s ability to wind down. Noise, glare, stale air and no escape keep it on alert.

At BREATHE, Studio Snoop’s installation at the Royal College of Art, visitors were invited to slow their breathing toward six breaths a minute inside a breathing membrane. Studio Snoop has watched a heart rate fall from 145 to 75 in a room designed for the body.

Hormonal change often shows up as disrupted sleep, night sweats, temperature swings, low mood and lower stress tolerance. Homes can help by giving real control over temperature, especially at night; breathable bedding and materials; a bedroom that stays cool and dark; good morning light to steady the body clock; and places to rest during the day.

Small changes, such as zoned cooling, a fan within reach of the bed, blackout and a calm place to recover, can matter more than a full renovation.

Yes. In a Harvard study, office workers’ decision-making scores dropped by around half when carbon dioxide reached about 1,400 parts per million, a level common in poorly ventilated rooms (Allen et al., 2016).

Opening windows on two sides for cross-ventilation, using extraction in kitchens and bathrooms, choosing low-emission materials and finishes, and adding a simple CO₂ monitor are inexpensive ways to keep a home or office clearer to think in.

The World Health Organization links loneliness to around 871,000 deaths a year (WHO, 2025). Design cannot replace relationships, but it can make connection easier or harder: a kitchen and table that invite people to gather, thresholds where neighbours meet, outdoor space that can be shared and rooms that work for both company and solitude.

Nervous System Design treats connection as a physical need alongside sleep and light.

Biophilic design brings nature into buildings: plants, natural materials, daylight and views. Nervous System Design includes this, but starts from the body rather than from nature. It asks what each person’s nervous system needs, including sleep, sensory load, breath, hormonal change and recovery, and uses nature, light, air, sound and layout as tools to meet those needs.

Studio Snoop also designs and tests new tools, such as hum-activated switches and kettles, grown mycelium materials and Tilly, a heart-centred AI designer.

Projects can start with a Biological Brief for your architect, or run from research and brief through design, prototyping and build to completion.
