I toured a 4,355-square-foot Four Seasons penthouse suite that costs $11,000 a night. The smallest room was my favorite.

Just beneath the Jackson Hole Mountain Resort, the Four Seasons is well-located for Grand Teton and Yellowstone National Park visitors.

Cole told BI that while the Four Seasons maintains top-tier service across all 133 locations, each is designed uniquely to suit the destination.

"There's a sense of place at every Four Seasons," she said.

With a "mountain modern chic" brand, this location of the 63-year-old, high-end hotel chain was ranked the best stay in Jackson Hole by US News.

Rates vary by season. In the peak winter season, the Granite Residence starts at $11,000 a night.

The stay includes ski and snowboard rentals for kids under 12 from mid-December to early January.

On the ninth floor of the resort, I stepped into a foyer with leather coat hooks and a pair of matching ottomans beneath. A framed, purple buffalo stared me in the face.

I felt like I was in a Western film — and that was the intention, according to Sarah Kennedy, CLB Architects' principal and lead design director of the penthouse suite.

"The majority of people who come to Jackson are really coming here to immerse themselves in nature," Kennedy said.

When CLB redesigned the penthouse, completed in the summer of 2024, Kennedy said the team maintained the hotel's style while elevating it.

"They had accented it previously with a bunch yellows and warm whites. So in terms of trying to modernize it, we kept the base palette of rich cherries and redwoods and offset it with whites," she said.

CLB selected a neutral color palette.

"The color palette is very simple, with natural textures," Kennedy said. "When we did try to bring color there, it was being inspired from the outside, like the soft blues and the greens of the natural landscape at the resort."

"The interesting thing about doing interiors here in Jackson is that the quality of light filtering into the space in peak winter and peak summer is completely different," Kennedy said.

So, CLB selects tones that complement light filtering into the interiors throughout the year.

"For example, I'm looking out the window now, and the amount of yellow and orange from all the leaves that are coming in is crazy," she said. "But you have to make sure that that same palette looks really good when there's a bunch of blue coming in from all the reflection of the snow."

"The subtle picking of these soft blues and neutrals is the way that we allow that palette to really feel immersive in nature but also stand the test of the seasons throughout the year here," she continued.

When sourcing furniture, Kennedy worked with an approved list of vendors, including Restoration Hardware and more local vendors. Select pieces also came from showrooms around the US.

The full kitchen had a gas stove. Guests can book a private chef to cook meals for them.

This huge pantry had all the kitchen appliances anyone could need, from blenders to crock pots.

Nestled in a corner of the penthouse, I opened the door leading to the guest powder room. It was the smallest room, with just a sink, toilet, and counter.

In such a luxurious space, I wasn't expecting to be wowed by the guest bathroom.

But I was wrong.

"The bread and butter of what we do here is connect people with nature," Kennedy said. "As it relates to pieces within the space, there are some wall coverings, particularly the one in the powder room that's got a mountainous scene."

The bathroom was covered in white wallpaper with simple black sketches of mountains on them. A gold and gray painting of a fox on the right matched the finish of the faucet.

It was a simple room, but every aspect felt thoughtfully considered, which is why it stood out to me.

Kennedy told BI that the penthouse design is as much about comfort as it is about nature.

"We're giving people the ability to feel like they're living a luxurious experience," she said.

That's why the penthouse boasts two living spaces with cozy seating.

"After you've been skiing all day, you don't really want a super flimsy thin profile chair. You want something that feels like it's hugging you," Kennedy told BI. "There's an element of, 'I'm just going to sit here and sip my hot chocolate and not move for four hours.'"

Cole told BI that much of the art in the penthouse was custom-made for the space, and guests can purchase the pieces.

The master bedroom also had a fireplace.

In all five bedrooms, CLB selected soft colors for the fabrics.

These bathrooms screamed luxury, with oversize tubs, multiple shower heads, and separate toilet rooms.

I thought it would be convenient for long-term guests and large families.

After I toured the Granite Residence, I thought it screamed Jackson Hole and the Wild West inside and out.

From the walls to windows and terraces, it was impossible to forget where I was while exploring the vast penthouse.
