Got a call last Tuesday from a homeowner in Nederland who’d been scrolling through design blogs and fell in love with these massive indoor living walls. You know the ones – floor-to-ceiling green walls that look like someone transplanted a chunk of rainforest into your living room. “It’s biophilic design,” she explained, using the term like it was some kind of magic password for environmental virtue. “All natural, totally sustainable.”
I had to bite my tongue. Hard.
Look, I get the appeal.
There’s something deeply satisfying about being surrounded by plants, having that connection to growing things. Hell, some of my best memories as a kid were helping my dad build planters in our backyard, watching how different plants responded to Colorado’s crazy weather patterns. But what passes for biophilic design these days? Most of it’s about as sustainable as heating your house by burning hundred-dollar bills.
Had a wake-up call on this whole thing about four years back. Client wanted one of those dramatic water features in their foyer – not just any water feature, but this elaborate wall fountain with integrated planters and specialized lighting. The designer had sold them on it as “bringing the outdoors in” and “reducing their carbon footprint through natural air purification.” The renderings looked incredible, I’ll admit. Very spa-like, very zen.
Then I started doing the math. The circulation pump alone would draw 200 watts continuously – that’s running a decent-sized refrigerator just to move water around for aesthetics. The humidity would force their HVAC system to work overtime during our dry winters. The specialized grow lights for the plants? Another 400 watts, fourteen hours a day. And the maintenance – Christ, the maintenance. Weekly water treatments, monthly plant replacements, quarterly deep cleaning. This thing was going to be an environmental nightmare disguised as nature appreciation.
When I presented the actual operating costs and energy consumption, the enthusiasm in the room just… died. “But it’s natural,” the homeowner kept saying, like saying the word “natural” somehow negated the laws of physics and the electric metre.
Here’s what really bugs me about this trend. People confuse the appearance of sustainability with actual sustainability. They’ll install these resource-intensive plant displays while ignoring basic stuff like proper air sealing or decent windows that would actually reduce their home’s environmental impact. It’s like putting racing stripes on a car and claiming you’ve improved the engine.
I worked on a remodel in Lyons where the previous designer had spec’d this elaborate aquaponics system in the kitchen. Fish tanks feeding plant beds, pumps cycling water, grow lights blazing away 16 hours daily. The homeowner was convinced they were becoming self-sufficient food producers. Reality cheque – the electricity to run that setup cost more per month than buying organic vegetables from the farmer’s market would’ve cost for an entire year. Plus, when the pump failed during a weekend trip, they lost both the fish and a month’s worth of herbs. Real sustainable food production involves working with natural cycles, not fighting them with technology.
The most sustainable “biophilic” projects I’ve done barely look biophilic at all, at least not in the Pinterest sense. They work with Colorado’s actual climate instead of trying to recreate some tropical paradise. Large south-facing windows that maximize winter solar gain while providing views of existing trees. Natural materials like local stone and reclaimed timber that age well in our weather. Outdoor spaces designed to be comfortable during our incredible fall and spring seasons.
Best example was a house near Ward where we positioned the main living areas to frame views of existing aspen groves. No artificial plant installations, no elaborate water features, no specialized lighting systems. Just really good windows looking out at trees that have been thriving there for decades without any human intervention. The family gets that nature connection everyone talks about, but the trees aren’t dependent on irrigation systems and grow lights to survive. They’re just… trees, doing what trees do.

I’ve also gotten skeptical of the whole “plants purify indoor air” claim that gets tossed around constantly. Yeah, NASA did that study showing plants remove certain pollutants. But that was in sealed test chambers, not real houses with actual ventilation systems. In a properly designed home, your air handling system does way more for air quality than any reasonable number of houseplants. If you want cleaner indoor air, invest in better filtration and source control, not a bunch of fiddle leaf figs that’ll probably die anyway when you forget to water them.
Don’t even get me started on those moss walls everyone’s obsessing over. Preserved moss that’s been chemically treated and dyed to stay green forever. It’s literally dead plant matter treated with glycerin and other chemicals, but people install it thinking they’re bringing nature indoors. It’s about as natural as plastic flowers, just more expensive and better at fooling people.
The whole industry has this backwards relationship with nature. Instead of learning from how natural systems actually work – efficiently, with minimal waste, adapted to local conditions – we’re trying to force inappropriate species to survive in artificial environments through sheer technological force. It’s like the opposite of biomimicry.
Real biophilic design means understanding your place and working with it. In Colorado, that means embracing our natural landscape instead of trying to recreate tropical rainforests in our living rooms. It means using materials that make sense here – stone that’s quarried locally instead of shipped from Vermont, wood from regional forests instead of exotic imports, plants that can actually survive our altitude and climate.
Had a client in Golden who initially wanted an indoor greenhouse room for year-round vegetable production. We ended up designing a south-facing outdoor growing area with season extension techniques – cold frames, row covers, strategic wind protection. She grows more food than she ever would’ve indoors, uses zero supplemental energy, and the whole setup cost less than the specialized glazing system for the indoor version would’ve. Plus, she’s actually gardening, dealing with real soil and weather and seasons, instead of managing a complicated indoor growing machine.
The sustainability piece gets even murkier when you look at material sourcing. That reclaimed barn wood looks gorgeous and feels environmentally responsible, but if it’s traveling 1,500 miles from some deconstructed farmstead in Ohio, the transportation emissions might outweigh any recycling benefits. Meanwhile, beetle-kill pine from right here in Colorado creates beautiful spaces with minimal environmental impact and actually helps with forest management.
I think what bothers me most is how this trend distracts from real environmental improvements. People get so focused on the visible symbols of green design – the living walls, the water features, the exotic plants – that they ignore basic building performance upgrades that would reduce their actual environmental impact by huge margins. Better insulation, efficient windows, proper air sealing, right-sized HVAC systems. That stuff isn’t Instagram-worthy, but it’s where the real environmental benefits happen.
The most successful biophilic projects I’ve been part of focus on passive strategies that actually work. Positioning buildings to maximize natural light and reduce artificial lighting loads. Using thermal mass to moderate temperature swings naturally. Creating outdoor spaces that extend the seasons when you can comfortably be outside. These approaches connect people with natural forces and cycles while reducing resource consumption instead of increasing it.
I’m not anti-plant or anti-nature connection. Hell, my office has houseplants, and I love them.
But I water them with leftover coffee and they survive on whatever light comes through the north window. They’re not on life support systems requiring specialized care and constant resource inputs. That’s the difference between having plants and having a plant installation.
When that Nederland client and I finally worked out a design that incorporated large windows framing existing pine trees, a covered deck for three-season outdoor living, and some carefully chosen native plants in appropriate outdoor locations, she was initially underwhelmed. No dramatic interior forest, no cascading water walls. But after living in the space for a year, she told me it was the most peaceful part of her home. And her energy bills showed what I’d predicted – the space actually reduced her home’s resource consumption while providing that nature connection she’d been after. Sometimes the best biophilic design is the kind that doesn’t announce itself with a bunch of expensive technology.
