I built a true timber frame home, all the joints are mortise and tenon and pegged, no nails, bolts or metal hangers.
~8 years ago my wife and I sold our 5 yr old side hall colonial in town and moved into a mobile home on 30 acres of farmland.
Year 1 - driveway, electric, house foundation, well, septic for the trailer and sited the mobile home.
Year 2 - took delivery of 14,000 board feet of rough cut white pine. Planed, sanded, cut/chiseled all the joints and applied 2 coats of oil. 1000 hours to cut the frame for a 3000 sq ft back hall colonial, 3 bedroom, 3 bath. This is a full 2 story colonial with 10 ft ceiling downstairs and vaulted ceilings upstairs, (8 ft at the exterior wall and 15 ft at the peak).
Year 3 - assembled the 4 bents, (posts, girts and rafters are 8x12's up to 19' long), hired a 5 ton truck crane and operator with timber frame raising experience, ("never hooked on to anything I couldn't lift....."), unfortunately my 2 story bents were too much for his truck. We then hired a 20 ton lattice crane and raised the frame with 6 good friends in a single day. I took the next 6 months to dry in the house, (39 windows, 2 sky lights, 3 exterior doors). The house was literally built from the inside out, first the timber frame, then 18,000 board feet of knotty pine, (1x on the walls and 2x for the ceilings), then put up a conventional 2x6 frame, (avoided stress skin panels due to wife's allergies), wired, insulated and then sheeted the exterior.
Year 4 - Plumbing, heating, AC, lighting, interior walls, (the main house is 31x41 and there are only 4 interior posts), cabinets, appliances, flooring, (2500+ sq ft of maple flooring. 300+ sq ft of tile), leach field. We then moved in, that summer we did the siding, (12,000 feet of cedar), added 3 decks and a porch, and added ~2 acres to the existing .5 acre lawn.
Needless to say I have a very understanding wife and our privately held bank was very accomodating, (1yr construction loan was stretched to 2+ years).
Year 5 - added a knotty pine sunroom and a 1000 sq ft timberframe garage, also with knotty pine walls and a vaulted ceiling. We also added a .25 acre pond in the front yard.
I'd do it again in a heart beat, it's truly a gigantic woodworking project. I grew up in a family of trades people, carpenters, plumbers and electricians but had -0- timber framing experience. Before we built we toyed with the idea of a log log cabin, I'm extremely happy we went the timberframe route.
