Lance and Holly Sheffield have been partners in life and business for 15 years, and they’ve tackled plenty of big challenges together — but nothing like the challenge of renovating 85 Nayatt Road in Barrington.

Just a few days after they purchased the home originally built by professional golfer Brad Faxon, the Sheffields began renovating, and they never stopped. After four years of nearly constant construction, reimagining, remodeling and redesigning, the Sheffields have listed the house for sale.

The asking price is a stunning $12 million — more than twice the price of the highest home sale in the history of Barrington.

What do you get for $12 million? It might be easier to describe what you don’t get.

The home, perched on a Nayatt Point hill that slopes down to Narragansett Bay, holds nearly 14,000 square feet of living space. The Sheffields have changed every inch of at least 13,000 of those square feet. Only a couple of small rooms remain as they were four years ago.

Every other space in the house has been completely made over — new floors, new colors, new tiles, new bathrooms, new fixtures, new lights, new mantles, new patterns, new trims, new moldings, new woodwork, new flow, new kitchen … new everything.

“We’ve remodeled five or six homes together, and this is the largest,” Holly said.

“The scale of this project is immense,” Lance added.

This was the plan before the Sheffields bought the house, which was designed in a very classic, ornate style. Holly said to him, “If we buy it, can you promise me that we will fulfill our vision and make this into a coastal home?” He agreed, and then they spent more than three years doing it, drawing inspiration from the homes of Nantucket, where they lived previously for several years.

“We had a home in Nantucket, and that’s such a special place. It really made an impression on us. So we wanted to carry that theme and that feeling to this house,” Lance said.

Both Sheffields are familiar with large renovation projects, but especially Lance. Originally trained as a furniture maker and carpenter, he studied business construction, launched his own business, and has worked in high-end construction and remodeling for more than 30 years.

His primary job for the past four years has been this house, where he personally did more than half the work — from installing more than 200 lighting fixtures himself, to ripping out carpets and laying down hardwood floors, including intricate custom patterns, tiling bathroom walls and floors, and blending custom woodwork throughout the home.

Holly, who is a designer and home decorator, was beside him throughout, dreaming up the look, feel and vision for this home, and challenging her husband to make it happen. She said the two of them work beautifully together, and disagreements are few — even when she tries to push the envelope on her vision.

“Every so often, I'll challenge him and say, ‘What do you think about this?’ And if it’s not going to work, then I come back to reality and say, ‘He’s been doing this for 30 years.’ I respect him for his craft.”

Yet most of the time, Holly and Lance found a way to make things work, reimagining everything about the horseshoe-shaped mansion. They added space and light with dormers. They knocked down some walls. They raised ceiling heights. They added a small addition to the east. And they greatly expanded the kitchen and made it the heart of the vast home.

A massive window bench in the new kitchen is testament to not just his skills, but hers as well. More than a home decorator, Holly is also a skilled seamstress. She made scores of pillows and custom window treatments throughout the house, all crafted in her studio on the third floor. The window bench holds about a dozen of her handmade pillows.

Show-stopping interior features continue room after room. The primary suite is stunning, with a sitting area offering views across the breadth of Narragansett Bay and several of its bridges.

The primary bathroom has a new shower built for a small party. But the real show-stopper is the makeup station, where Holly infused a surprising touch of high-tech creativity. She designed a makeup mirror, powered by a small lift, that rises from beneath the counter and then descends when not in use, hidden by a smooth slab of countertop. To the unknowing, there is no sign of the innovation within.

The Sheffields of course had help along the way. Though they did more than half the work themselves, they relied on lead contractors Dave Butera and Paul Doherty.

The finale of the Nayatt Point makeover is the outdoor space — remodeled, expanded and transformed into a resort-like escape. It includes infinity pool, waterfall, grand cabana with fireplace, spa and lighted tennis court.

The home is listed by the Kirk-Schryver Team at Compass. Principals Lisa Schryver and Elizabeth Kirk released a statement when asked about the challenge of a $12 million listing in Barrington: “At $12 million, this estate represents not just a milestone — but a true redefinition of luxury in Barrington. It’s in a class of one, a coastal retreat reflecting a level of scale, quality, and amenity that undeniably command an ultra premium. 85 Nayatt transcends traditional valuation benchmarks — aligning more closely with a small collection of trophy properties that line New England’s coveted coastline and islands, not just Barrington proper.”

To the Sheffields, 85 Nayatt is both home and the realization of a vision they shared together four years ago. "We work really, really well together — really well,” Holly said. Asked if the final product aligns with their original vision, she gave an enthusiastic yes, and both said it actually exceeded all expectations.

Their collaboration over the past four years is unforgettable, and they’ve created a coastal home unlike anything Barrington has ever seen before.
