The 40th iteration of the model home, which annually features the latest and greatest in building methods and products, was unveiled this week at the International Builders' Show in Las Vegas.

The modern four-bedroom, seven-bathroom home spans nearly 7,600 square feet in a gated, upscale community in Henderson, Nevada, about 20 minutes from Las Vegas.

The two-storey home, which has a two-level pool, private patios off most bedrooms and an outdoor kitchen, is on the market for approximately $15 million.

This newly built home also features a lift between floors, an office with a private bathroom, and a two-car garage.

"What's most impressive about this house is everything you don't see," said architect and builder Michael Gardner of Luxus Design Build in a press release." When you walk into the home, the simplicity of it and the complexity behind it, to me, is one of the coolest parts of it."

Gardner explained that they focused on creating a soothing oasis away from the busy Las Vegas Strip.

"We wanted to design the house in a way that made sure it had a private feel," he says. It has "that sense of tranquillity" wherever you are.

From the moment you enter the home, the home is as much about the outdoors as it is about the indoors. The entrance has a comfortable seating area and is lined with striking native plants. There is just one thing missing. A roof.

This indoor-outdoor concept is embedded in the design of the residence. With the exception of one bathroom, all the bathrooms in the residence have private access to the outdoors.

The upper terrace and the lower pool patio are used to relax and enjoy the glorious views of Las Vegas below. They are both equipped with outdoor kitchens, making it easy to entertain or just make yourself a cocktail while relaxing in the fresh air.

The ground floor courtyard is one of the more luxurious features of the home. An infinity pool seems to blend in with the landscape and the lower level is for those who want to take a swim in the lanes. There is the requisite hot tub, a pergola, multiple fire pits and ample seating for those who want to live outdoors as comfortably as possible.

Considering the region's warmer winters and less rain, the outdoor space can be enjoyed for most of the year.

The $15 million price tag for the home seems high until you experience the views.

Gardner says the lot on which the house sits was chosen for its elevation and the views to the north and northwest of Las Vegas, the mountains and the rocky outcrops nearby.

There are some beautiful snow-capped mountains here and a lot of people don't realise we have such great views in Las Vegas," he said.

Floor-to-ceiling windows abound and almost every square foot is flooded with natural light.

"You can bury yourself in there and take in the beautiful view," says interior designer Elma Gardner, of By Design.

The main bathroom is an eye-catcher. The stunning grey natural stone shower has white and beige swirls. It has two side-by-side showers (for a double bath?) that faces a bright white soaking tub.

Opposite it is a sauna that looks like a built-in lounge chair to sit in while the toxins flow out of your body.

A double-sided Jack-and-Jill vanity, about the size of a kitchen island, highlights this room with a floating mirror separating each side.

And we can't forget the double water closet, right next to each other. Yes, this part is a bit odd. With seven bathrooms throughout the house, it's a mystery why anyone would want to go to the bathroom at the same time as anyone else, just a few feet apart - even if each person is in a private, completely enclosed space.

Did I mention that the bathroom was very large, about half the size of an old one-bedroom flat I once rented?

Wood-toned kitchen cabinets, fridges and closets have been a growing trend of late. We're not afraid to stand up and say it. We just don't like it.

I don't need my fridge to look like the walls of a country cottage. It is a fridge. If it's 3am and I want a snack, I'd rather it didn't blend in with the cupboard.

We also weren't keen on the wood-toned storage in the walk-in closet that is part of the master suite. The storage space is excellent (so much room for shoes!) , the built in steamer that you hang items in and come out without wrinkles, hidden behind a mirror, is genius.

Also, the lighting is stylish and pleasing to the eye. But the effect of all that dark wood gives the room an unwelcome, masculine, detached energy. It doesn't feel like a place where you'd want to try on clothes and linger.

While we appreciate a good glass of wine (or a bottle if it's one of those days), the prominent wine fridge on display in the kitchen seems to take up a fair amount of valuable space. Along one wall are four side-by-side fridges, each the size of a small door, each with 11 shelves (I counted them) and each with room for multiple bottles.

Then, at the back of the living room is a decorative, but functional, wine display cabinet

Whoever moved into that home would need quite a collection to even fill up the storage space to do so. That's a lot of pressure.

We also didn't like the flooring throughout the house. The terrazzo flooring in the spacious offices on the main floor reminded us of primary school bathrooms from the 1980s. At the same time, the grey solid wood flooring in most parts of the house made it feel a bit tired.

For the past few years, this grey-toned flooring seems to have been a staple of any of the home improvement shows currently being shown on HGTV. Soon, it will look dated - if it isn't already.
