The venture, set on 66 acres of land near Launceston, will feature a six-bedroom farmhouse with a dining room, whisky room, library and a communal living room.
Guests will be sold rooms inclusive of breakfast and dinner (from £160 per person) which will be served in the 12-cover dining room at a communal table.
The menus will be 'ever-changing and evolving' with produce sourced from the farm and local producers. Dishes will include small and large sharing dishes such as Whole pit baked Mangalitza ham and creamed kraut; Rabbit, cobnut and nettle sausage, House curds, peas, mint and sorrel, and desserts such as Blackcurrant leaf junket. Non-resident locals will also be given the option to dine for £50.
Adams and Bloomfield, who met five years ago, confirmed they had acquired farmland together in April.
The pair have a shared desire to create a business based as close to the source of the food as possible. Adams will be based at the farm and will predominantly run the operation, returning to London on a weekly basis to work at Pitt Cue while Bloomfield will frequently visit from the US.
Coombeshead Farm will open on 6 July.
