Like its north metro neighbor Avalon, a Forsyth County live-work-play utopia with a similarly fancy name — Halcyon — is forging ahead, and a fresh rendering has emerged to preview exactly what it could be.

With 135 acres and some $370 million behind it, Halcyon is one of five transformative mega-developments in the works for the affluent upper reaches of metro Atlanta, which could theoretically bring almost 7,000 residential units, more than 700 hotel rooms, 6 million square feet of office and commercial space, and unneeded car traffic.

Halcyon will be the northernmost project of its type planned on the Ga. Highway 400 corridor. Across the border from Alpharetta, it would be connected to 40-plus miles of greenways, and as such, its leaders plan to emphasize outdoor living. Once finished, it would encompass an area more than two-thirds the size of Piedmont Park.

Halcyon's developers broke ground last month and seem optimistic the first phase will open in fall 2017 with a whopping 125,000 square feet of retail, 65,000 square feet of offices, and a 110-room hotel. (These guys must be fast).

With the initial phase, Halcyon watchers can also expect to see 87 homes, 155 townhomes — with prices starting in the high $400,000s — and 448 apartments, reports the Milton Herald.

Plans for the commercial village will include "a movie or entertainment venue, gourmet market, outdoor outfitter, up to 10 local and regional full-service and fast-casual restaurants, a boutique fitness club, and service retail," the newspaper reports.
