Timber frame construction is one of the oldest construction methods, and many frames built over a thousand (yes, a thousand!) years ago are still standing - and still in use – a testament to the both the framers’ skill and the timber frame method itself.   This sustainable form of building does not use metal, including nails, for joinery.  Rather, each building frame is a unique wooden sculpture composed of large wooden beams that lock together with wooden pegs to form the visible interior (known as mortise and tenon joinery).  This results in a frame that is structurally stronger than conventional platform construction, and actually uses less wood. 

In addition to the sheer beauty of the timber frame itself, there are also eco-advantages to this type of construction.  The use of natural timbers, as compared to brick, concrete or other fabricated products considerably reduces the carbon footprint of a home build.  Timber frames can also reduce the energy used in heating the home because they provide a high level of insulation.  Premier timber frame manufacturer, Sweet Timber Frames, in particular, utilizes a greener method of insulation than standard structural insulation panels (SIPs, which are frequently used in timber frame construction).  “Since there is often an enormous amount of waste with the installation of typical SIPs, we prefer a much greener insulated wall, made here in Maine,” says owner John Sweet.  “This reduces the need for air exchangers, which most SIPs walls need.  It also gives us an R-34 factor and a LEEDS certified wall, which is hugely beneficial to both the environment and the homeowner.”

Located in Mt. Desert, ME, Sweet Timber Frames (www.SweetTimberFrames.com) has completed the raising of an exceptional barn frame in Sorrento, ME, just outside Bar Harbor, and is now putting the final touches on cutting the frame for the main home.  John Sweet says, “The use of timber framing was essential for this family - the property is breathtaking in every way, and they needed a barn and home to match.  We are more than happy to oblige.”  Furthering their eco-efforts, all the wood products that Sweet Timber Frames used in the construction of this home were locally sourced from Maine.

The frame that they’ve just completed erecting is an impressive two story 36’ x 60’ barn structure, which is built solely from traditional mortise and tenon-joined hemlock frames, and like all Sweet frames, there are no metal supports or nails used whatsoever.  The pegs act as a locking mechanism with the joints of the timbers, so that when the frame of the house was assembled on-site, the only element holding the entire structure together is wood.

The two story 36’x60’, 4320 square foot barn was raised first.  On the first floor, this barn structure will have a four-car parking area on the north side, and a living area and kitchen on the south side.  The second floor will include living space and bedrooms, with ten dustpan dormers upstairs and double windows in each dormer.  The homeowners have also included additional eco-efficient features, including 48’ long solar flat plate hot water heat exchanger panels (located on both the barn and the house), which will work in conjunction with a wood gasification boiler.  Wood is carbon neutral and a renewable resource, so both the timber frame and the heating of it will be a win for the environment. 

The frame for the 6480 square foot main house is being finalized now, and will be raised shortly.  Keep an eye out in Smart HomeOwner for updates on the process of this impressive house frame – from start to finish!
