I Built the Ultimate Biohacking House — Here's What’s Inside

Ben has a dedicated bright light in his office that simulates the full spectrum of sunlight. He mentions flipping it on for the initial 20 minutes of his day to signal morning to his body. This practice mimics outdoor morning light exposure and is especially useful when natural light is insufficient. The light is distinct from the overhead circadian bulbs; it's a panel that can be positioned in front or behind him while he works.

The Vasper system pairs blood flow restriction cuffs with a chilled water vest, an earthing pad, and a recumbent cross-trainer. Ben added red lights above it so he gets photobiomodulation during exercise. An oxygen bag connected to the machine lets him switch between hypoxic air (simulating 18,000 ft) and 90%+ oxygen for interval-style hypoxic/hyperoxic training. He considers this one of the most efficient ways to get a total-body workout, claiming it beats traditional cardio and lifting for time efficiency. The protocol is 21 minutes, three times a week, and it serves as his primary cardiovascular training.

The house's programmable LED fixtures have three modes: daytime (blue-rich), twilight (amber, after 4:35 pm), and full red (evening). Ben demonstrates toggling to full red mode, emphasizing that this prevents circadian disruption from artificial light at night. The bulbs are also low-EMF and flicker-free, reducing another potential stressor.

Instead of Wi-Fi, every room has Cat 8 metal-shielded Ethernet ports, and Ben provides extenders for devices. The entire home's wiring is metal shielded, and walls are painted with EMF-shielding paint, reinforced by shielding fabric and window film to block external signals. The goal is to avoid continuous Wi-Fi exposure while still having internet access. The cell phone signal works, but he openly admits it's a little weaker than outside, which he views as an acceptable trade-off.

Copper wires beneath the wood floors connect to a grounding rod driven into the earth. Ben asserts that the system obviates the need for grounding mats or earthing sheets. Both he and his dog (who doesn't wear shoes) are constantly grounded. He credits the concept to his building biologist Brian Hoyer and suggests listening to his podcast for the hardcore science. The approach is a structural substitute for frequent barefoot outdoor time.

Ben describes the 14-stage filtration system that removes contaminants, then adds back minerals, dissolves 40 ppm oxygen, and finally passes through a structuring unit that allegedly alters the hydrogen-bonding pattern for enhanced bioavailability. He uses the structured outlet for his large morning glass and for making coffee. The second faucet provides hyper-oxygenated but non-structured water for other uses. The system is positioned as a luxury health upgrade akin to drinking from a pristine natural spring.

Greenfield describes his 14-stage RO filter (Ofora) that includes a remineralization cartridge and an oxygenation module. The glass initially appears dark and cloudy—which alarmed him—but he realized that's 40 ppm of oxygen suspended in the water. Additionally, a separate under-sink structuring unit changes the hydrogen-oxygen bonding pattern before it comes out of a dedicated faucet. He uses the structured water for his morning glass, coffee, and other staples, while the hyper-oxygenated but non-structured water comes from another tap. The idea is to mimic the properties of natural spring water that has contact with minerals and motion-induced vortex energy.

Visitors often ask for the Wi-Fi password only to be told there is no Wi-Fi. Every room has an Ethernet port, and behind beds, under desks, and all over the house, extenders and direct connections allow any device to be hardwired. The internal wiring is metal-shielded, and Cat 8 metal-shielded Ethernet cable feeds the entire home. On top of that, walls incorporate shielding paint and fabric, and windows have shielding film to block incoming radio frequencies from cell towers, neighbor Wi-Fi, and FM towers. Ben admits the cell phone signal is 'a little weaker inside the home than it is if I step outside' but asserts that calls can still be made. The aim is to drastically reduce ambient EMF exposure indoors without becoming a digital hermit.

He explains that concrete is conductive, but many upper floors or finished surfaces lose that connection. By installing copper wiring beneath the wood floors and linking it to a grounding rod, anyone walking barefoot or in non-insulating footwear (the dog included) becomes grounded. He emphasizes he went 'deep nerdy style' into the science with building biologist Brian Hoyer on his podcast. The system aims to replicate the natural healing frequencies and negative ion absorption of the earth, reducing inflammation and aiding sleep and recovery.

Flicking the wall switch cycles through three modes: bright daytime light, amber twilight for after 4:35 pm, and deep red evening mode. Ben also installed separate incandescent fixtures (e.g., above the dining table) that he combines with the LED ceiling lights, arguing that mixing LED and incandescent gets much closer to full-spectrum sunlight than either alone. This dual-bulb strategy is intended to support natural circadian rhythm, mood, and hormone production throughout the day, especially in the dark Pacific Northwest winters.
