Luxury farm resort uses CLT framing and geothermal system to boost sustainability

Construction was recently completed on a 325-acre luxury farm resort in Franklin, Tenn., that is dedicated to agricultural innovation and sustainable, productive land use. With sustainability a key goal, The Inn and Spa at Southall was built with cross-laminated and heavy timber, and a geothermal variant refrigerant flow (VRF) heating and cooling system.

The four interconnected buildings totaling 95,000 sf feature 62 guestrooms, an executive boardroom, 15,000 sf spa, all-day dining restaurant and bar, and a 3,700 sf signature seed-to-fork restaurant, January, featuring items grown on-site. Many guestrooms include wood-burning fireplaces, exposed wood beams, and large windows overlooking the natural landscape.

Cross-laminated timber (CLT) and heavy timber were used to frame the structures. Sloped CLT for the lobby eliminated the need for cross bracing and framing to create a large, open space at the main entrance.

The HVAC system employs a water-source geothermal variant refrigerant flow (VRF) system. This system consists of 110 geothermal wells 400 feet deep under the parking lot connected to a geothermal loop within the building. The geothermal system is also used to produce hot water for the guestrooms, spa, and kitchens.

Conceived seven years ago as a biodynamic working farm, Southall, located near Nashville, includes orchards, greenhouses for hydroponic production, and a seasonal farm stand. The working farm employs both advanced farming technologies and heritage farming techniques—from hydroponics and aquaculture to rotational grazing, permaculture, and terracing—to create a farm of the future with an old-world reverence, according to a news release.

Southall also includes an event center and 16 standalone cottages. Outside of the sustainable working farm and luxury resort, 97% of the property will be maintained as green space.

“Southall’s emphasis on nature and sustainability drove the design, construction and material selection,” said John Sheridan, Executive Vice President of McHugh Construction. “We’re so accustomed to going vertical and building luxury hotel and mixed-use projects in urban areas with tight construction sites; the opportunity to apply our hospitality expertise in building a five-star resort among the bucolic rolling hills of Middle Tennessee was an honor, a challenge and, frankly, a magical experience.”

The recently opened Michigan Central Station in Detroit is the centerpiece of a 30-acre technology and cultural hub that will include development of urban transportation solutions. The six-year adaptive reuse project of the 640,000 sf historic station, created by the same architect as New York’s Grand Central Station, is the latest sign of a reinvigorating Detroit.

Studio Gang designs agricultural education center for the New York City Housing Authority

Earlier this month, the City of New York broke ground on the new $18.2 million Marlboro Agricultural Education Center (MAEC) at the New York City Housing Authority’s Marlboro Houses in Brooklyn. In line with the mission of its nonprofit operator, The Campaign Against Hunger, MAEC aims to strengthen food autonomy and security in underserved neighborhoods. MAEC will provide Marlboro Houses with diverse, community-oriented programs.
