Yellowstone Refformation

A modern organic whole-home renovation and furnishing project in New Jersey

Home TourWatch the Home TourYellowstone Refformation Home Tour

Yellowstone Refformation is an extensive whole-home renovation and furnishing project created for a family seeking more space, a slower pace and a closer connection to the land. Set on a wooded property in Mendham, New Jersey, with a pool and pool house, the residence combines the character of a traditional country estate with the warmth and simplicity of modern organic design.

This was not a new build. Ellie Mroz Design and Michael Robert Construction reimagined the existing home from the inside out, creating a better-than-new residence that feels established, comfortable and completely personal.

Design, build and furnish as one project

Every area of Yellowstone Refformation was considered as part of one continuous design story. The Ellie Mroz Design team developed the interiors and furnishings while working alongside Michael Robert Construction throughout the renovation, allowing architecture, material selections, custom millwork and furniture planning to support one another from the beginning.

The result feels collected rather than newly installed. Old-world influences, warm woods, handcrafted finishes and tailored furnishings temper the scale of the residence and make its rooms feel welcoming and usable.

Bringing the landscape inside

The relationship between the house and its surroundings became one of the project's defining ideas. Cedar, stone and other natural materials establish the exterior character and continue inside through fireplaces, flooring, millwork and textural finishes.

Multiple rooms connect directly to patios and outdoor entertaining areas, including the primary suite. From the rear of the house, the architecture opens toward expansive views, a swimming pool and a fully appointed pool house. Rather than treating the outdoor areas as additions, the team designed them as an extension of the home.

The kitchen at the heart of the home

The kitchen balances traditional craftsmanship with a more relaxed, modern sensibility. Deep blue cabinetry grounds the room, while a sculptural white hood, expressive marble and warm metal details bring light and refinement.

The dining room and pantry

An adjoining pantry and serving area expands storage and preparation space without interrupting the visual calm of the main kitchen. The dining room continues the natural material palette, with furnishings and lighting selected for both everyday family meals and larger gatherings. Arched steel-and-glass doors create a direct connection to the covered patio.

A family room designed for gathering

The family room was planned as the home's principal gathering space. A substantial stone fireplace creates an architectural focal point, while layered upholstery, built-in seating, natural fibers and sculptural lighting soften the room's generous proportions.

The furniture arrangement supports conversation, family time and entertaining. Each selection was scaled specifically for the architecture so the room feels intimate without appearing under-furnished.

Beautifully practical family spaces

Function was treated as an essential part of the design. The mudroom combines custom oak cabinetry, brick flooring, concealed storage and integrated accommodations for the family's dogs. Its durable materials give the room an established, almost European utility-room character.

Two separate laundry rooms serve different areas of the house. The first-floor laundry is light and understated, while the upstairs laundry introduces richer green cabinetry.

A color-drenched workspace

The home office is color-drenched in a deep forest green, with the cabinetry, walls, trim, ceiling and doors all finished in the same shade. The color-drenched treatment gives the room a quiet, enveloping atmosphere and allows the detailed millwork to read as one architectural element.

Natural wood, leather and carefully selected desk accessories complete a workspace that feels formal enough for meetings but comfortable enough for daily use.

A private sequence of restorative spaces

The primary suite unfolds as a sequence rather than a single bedroom. A private office and anteroom create a transition from the rest of the house, leading into a bedroom anchored by a leather bed, warm wood furnishings and soft natural textiles.

In the primary bathroom, pale stone, restrained cabinetry and a spacious wet-room arrangement create a calm environment. Direct access to the outdoors strengthens the suite's relationship to the landscape and offers the homeowners a private way to enjoy the property.

The second-floor landing and family wing

Upstairs, the landings work as more than circulation — built-in nooks and light-filled sightlines turn the in-between spaces into places to pause, read or study. The children's bedrooms and bathrooms, seen in the gallery below, were designed to reflect individual personalities while remaining connected to the home's broader palette through color, patterned wallcoverings, zellige tile and tailored furnishings.

Room to gather, study and unwind

A shared lounge, gym and built-in study or reading nooks provide flexible spaces for homework, recreation and time with friends. The bright movie room offers a playful alternative to a traditional dark theater, complete with comfortable lounge seating and a dedicated candy station.

A guest-ready extension of the home

The pool house completes the indoor-outdoor experience. Designed as more than a seasonal changing room, it includes a bedroom, kitchenette and bathroom, allowing it to support poolside entertaining as well as overnight guests.

Soft neutrals are balanced with deeper cabinetry and built-in elements. The restrained palette lets the architecture, surrounding greenery and proximity to the pool define the atmosphere.

The material and color story

A custom white sets the primary neutral across general walls, trim and ceilings. From there the house works in drenched color, room by room: deep forest green on the office millwork, walls, trim, ceiling and doors; a warm putty on the pantry and serving-area millwork; a softer sage on the second-floor laundry cabinetry; a cool off-white keeping the primary bathroom light; and a muted green-grey grounding the pool house bed surround and kitchenette.

Across the house, cedar, stone, oak, brick, marble, zellige tile, woven fibers and warm metal details repeat and relate, so the rooms read as one environment rather than a series of separate decisions.

The finished house

Yellowstone Refformation demonstrates how an extensive renovation can feel both transformative and deeply established. Although almost every part of the property was reconsidered, the finished home does not feel overdesigned or newly imposed. It feels comfortable, connected to its setting and ready to support family life for years to come.
