Everything you need, in one private place

We designed the Stargazing Villa to hold everything you need in one private place — no crowded lobby, no shared walls, nothing between you and the view. It adapts to whoever comes: a couple, a family, friends, a working retreat. What stays the same is why we built it: wellness, new experiences, and travel that respects the place it happens in.

  • Two telescopes: a Celestron Origin and a Celestron 10-inch Dobsonian
  • Kitchen, a fire pit on the patio, and an observatory pad for the telescopes
  • 100% off-grid and solar-powered, with a red bulb in every exterior light to keep the sky dark

The service

  • Personalized or self check-in — if you check in on your own, we walk you through the villa the next day
  • On-site guest support by call or text, day and night
  • Housekeeping between stays. During your stay, ask for a simple replenish (fresh towels, coffee pods) or full housekeeping with the bed made

The story behind the villa

What we set out to build

Most hotels and big resorts are designed around throughput: one lobby, long corridors, rooms separated by a wall from strangers, and the view shared through a window. We started from the opposite end. Kosmos is a micro-resort — a handful of private villas spread across 40 acres, each one complete on its own. The Stargazing Villa was designed to adapt to the group and the purpose: a quiet stay for two, a family trip, friends around the fire pit, or a few days of focused work, and — when the whole resort is booked together — a retreat or a celebration. Whatever the reason for coming, the principles don't change: wellness, new experiences, and conscious tourism that keeps the land, the sky, and the community around it intact.

Architectural rendering of the final Stargazing Villa design at dusk: a glass geodesic living dome, a white bedroom wing with a round window, a clear stargazing spa dome, a sunken fire pit on the patio and an observatory deck with a telescope, below the snowcapped Sangre de Cristo Mountains and the Great Sand Dunes
Rendering of the final design. Villas 1–3 are the first steps toward it.

The original concept

The Galactic Dome

Kitchen, living room, bar, an office and study, an upstairs loft and a meditation corner — each villa themed after a constellation.

The Sleep Capsule

A spacecraft-inspired bedroom wing built around one goal: the best sleep of your trip.

The Stargazing Spa

A private jacuzzi under a clear dome — the Milky Way without leaving the hot water.

The Celestial Patio

A sunken fire pit, a smokeless grill and seating facing the Great Sand Dunes.

The Observatory Deck

A Dobsonian telescope and a built-in round hammock for lying back under the sky.

This is the final design we're building toward — the luxury stargazing retreat we set out to create in one private footprint. Villas 1–3 are the first of 19 Stargazing Villas and 18 Kosmos Suites, and not every piece exists yet: today there is no loft, no sunken fire pit and no built-in hammock. For what each villa includes now, see Phase 1 — Open Now, above.

Six versions

How the Stargazing Villa evolved

It took six designs to get from the first sketch to the villas you can book today.

Evolution of the Stargazing Villa — six design versions from initial wooden concept to final architecture
  1. V1 — Initial design. A simple wooden cabin.
  2. V2 — Modular design. Container homes, for a more practical build.
  3. V3 — The sleep capsule. A modular approach using US suppliers.
  4. V4 — Making the villa luxury. Thinking bigger, with more square footage.
  5. V5 — Connecting three structures. Two containers joined into one design.
  6. V6 — Final architecture. A geodesic living dome, a hempcrete bedroom wing and a clear stargazing spa dome.

100% off-grid

How a villa runs with no grid at all

There are no utility lines out here. Every villa makes its own power, draws its own water and handles its own wastewater — which is part of why the sky stays this dark.

Power

Solar arrays with battery storage. Each villa has its own battery and controls in its mechanical room.

Water

Our own well, 70 to 80 feet deep.

Wastewater

Three engineered septic systems designed for the full resort. The first is complete.

Walls

Hempcrete — hemp and lime — a natural building material, built by our own construction team.

Light

Every exterior light carries a red bulb. It keeps light pollution to a minimum and your night vision intact — and it looks pretty cool.

More than a place to stay

A working model for healthier, more efficient homes

Every Stargazing Villa doubles as a proof of concept: a single-family home that is healthier to live in, cheaper to run, and independent of the grid.

Geodesic dome

A dome encloses the most space with the least surface, so there is less exterior to lose heat through — and its triangulated frame is exceptionally strong for its weight.

Hempcrete and natural plaster

Hemp-and-lime walls finished in natural plaster: breathable, non-toxic and naturally resistant to mold and pests, helping keep indoor air and humidity healthy.

Radiant heated floors

Warmth rises gently from the floor instead of blowing through ducts — even heat, no forced-air dust, and less energy needed to feel comfortable.

Off-grid by design

Solar with battery storage, a private well and engineered septic: no utility bills, no reliance on the grid, and lower costs to run year after year.

Our building partner

Built with Naturalia

Every Stargazing Villa is built by Naturalia Construction, our sister company. Naturalia isn't a typical general contractor chasing volume. It chooses its projects by the impact they will have on natural building — supporting the development of Kosmos first, and putting its remaining bandwidth into education — and it shares its methods openly.

It started with land. Naturalia has divided more than 1,300 acres into homesteads of 35 acres or more across three San Luis Valley counties, planned around cluster-subdivision and Blue Zones principles, and helped 25 first-time buyers become landowners between 2024 and 2026 — many through no-credit-check private financing. When those new owners asked how to actually start building on raw land, Naturalia lent machinery for roads and trenches, then took on land clearing and utility work, and grew into a one-stop shop for building in the valley: from a single task, to a finished home with its Certificate of Occupancy.

The same values run through everything we build: hempcrete, sugarcrete and natural plaster in place of toxic materials; off-grid systems in place of utility dependence; and lighting that protects the night sky — and the wildlife that depends on it.

DarkSky Approved

How we earned Colorado's first DarkSky Approved Lodging

Certification took more than a year of work with DarkSky International — and it shaped how every villa is lit.

  1. February 2025

    DarkSky International reached out to us first — interested in featuring Kosmos as an example of how to design and landscape a property to be dark-sky friendly.

  2. March 2025

    Application opened with DarkSky International's lodging program.

  3. April 2025

    Installing the fixtures, we chose shielded lights pointing down, with red bulbs. DarkSky's lighting manager weighed red against amber with us: red best protects night vision, amber looks more natural and is easier for photographers. We chose red.

  4. May 2025

    Sky-quality readings on a clear, moonless night measured 21.56 to 21.65 on a sky quality meter. DarkSky looks for 21.2 or darker.

  5. June 2025

    A full exterior lighting inventory, a habitat identification report, a lighting management plan and an outreach and education plan were submitted and approved.

  6. Late 2025

    Final review. Full drapes were added to the clear spa domes so light from inside stays inside — checked and approved by DarkSky.

  7. April 28, 2026

    Certified: Kosmos became Colorado's first DarkSky Approved Lodging. Sky quality is measured again every year as part of the annual review.

The lighting itself is deliberately simple. Every exterior light on the villas is the same fixture — a fully shielded, downward-facing wall cylinder by Progress Lighting, on a plain switch. No floodlights, no uplighting, no light thrown sideways across the valley. And every one of those fixtures carries a red bulb, which keeps light pollution to a minimum and your night vision intact — and looks pretty cool.

Why it matters: artificial light at night disrupts migrating birds, pollinators and the nocturnal wildlife of the valley, and it erases the sky that brings people here in the first place. Keeping light to a minimum isn't a feature we added — it's how we, and Naturalia, build.
