There is no easy answer to this question because there are so many factors that go into the price of a timber frame. For example, the timber species, complexity and even the type of joinery can greatly alter the price of a timber frame. These factors put the cost of a timber frame in the range of $50,000 to $500,000 and up. Typical residential customers usually spend around $75,000-$200,000 for an addition, $50,000-$250,000 for a barn, $9,000-$50,000 for a pergola and specialty projects can be anywhere on that spectrum.
HLTF provided the structural trusses as well as the tongue-and-groove decking for this Bonsai Studio in Kennett Square, PA.
The Douglas Fir trusses were designed with solid king-post and curved glued-laminated (glulam) bottom chord to provide an elegant finish.
Glulam timbers are extremely versatile and strong and can make possible dramatic shapes, spans and curves, which would be almost impossible with normal timber stock.
The rain chain on the exterior of the Bonsai Studio is a beautiful architectural, not to mention functioning, element.
These past several weeks the crew at HLTF has been cutting out, pre-fitting and staining a new Douglas Fir, heavy timber framed pavilion. Here the crew is working on pre-fitting the pavilion in our shop.
This pavilion was raised today in Gladwyne, PA. Here the pavilion is being readied to be flown into place by the crane.
The pavilion had to be flown over the existing house and into place because of the site layout.
Once we have all the pictures, a full story on this Gladwyne Pavilion will be posted, so be sure to check back in.
The HLTF crew raised this two-story 24 x 36 timber framed carriage shed in Kennett Square, PA at the end of March. The owners are planning to use their new timber frame as a shop/garage on the first floor and the second as an art studio.
The guys arrived on site early Monday morning with two trailers of timbers and pre-assembled king post trusses.
The first order of business was to get the site staged for an organized raising. This process includes orienting and setting the crane in the most advantageous position available, designating a timber assembly area and ‘shaking out’ the stacks of timbers.
After the stage was set, the crew then built the walls in sections on the ground so they could then have the crane fly them in to place.
Once in place, the sections were secured and braced off so the crane could fly the next assembly into place. When two assemblies were positioned and braced, the connecting timbers were then carefully installed, plumbed and pegged.
The crane and ground crew worked in concert as assemblies were flown into place the ground crew installed single members growing the frame section-by-section and piece-by-piece.
The lower level of the carriage shed will have two bays for vehicles and an extra bay for a garden tractor and workshop. In timber frame construction the entire shell of the building is on the exterior side of the frame so that the timbers can be exposed on the inside of the structure. In this case, the posts for the lower level are the same posts that define the studio on the second level.
Once installed, the barn flooring and heavy timber floor joists will be the only barrier between the lower and upper levels of the building.
The major purlin and structural ridge bear on the king post trusses so, before they could be installed, the trusses had to be flown, plumbed and secured.
Upon the installation of the king post trusses, the major purlin and structural ridge were lowered into their final resting place. These members in this frame had to be installed piece-by-piece taking up crane time. During this time, other members of the crew installed timbers, which were manageable by hand in another area of the building.
Among other timbers, the second day of the raising focused mainly on the roof rafter system.
The dormers were put together on the ground as much as possible and were then positioned in place by the crane. After that, the crew installed the smaller members completing the dormer.
Below is the timber frame skeleton, which is currently being finished by our sister company, Hugh J. Lofting Construction Management Services, LLC.
The HLTF crew is finishing the pre-fit of our new carriage shed which will be raised next Monday.
Here the crew is using the lift in our shop to help move around the large timbers. the rest they do by hand.
The reason the crew pre-fits is to make sure every all the joinery is tight and so there are no surprises when they get on site.
The guys are now finishing up the sanding and staining to be all ready for Monday. We are all excited for the raising event! Check back for raising photos!
All packed up and ready to go!
The drawing and the timber frame, pretty cool comparison.
We recently designed and built the timber frame portion of this garage/studio in Berwyn, PA.
One of the highlights of this project is the striking cupola that sits atop the frame.
The entire frame was pre-fit in our shop, as all of our projects are.
The cupola was built on the back of a trailer and trucked to the site for an easy install.
Our crew was responsible for raising the frame, installing the cupola and decking the frame.
Because this garage/studio is a timber frame, the desired 30’ Clear span could be achieved.
Two-tiered truss system provides cantilevered hip rafter support for the 10’x10’ cupola.
The timber frame is comprised of #1 FOHC kiln dried Douglas Fir. The kiln-dried material reduces timber shrinkage and insures tight joinery for the life of the structure.
The timbers are joined with concealed steel connections and expressed bolts all of which were designed in-house.
Flying the pre-assembled cupola and other components allowed for the complete frame to be raised and decked in 4 days.
Arts and crafts was the inspiration for the original frame design.
