We recently finished the first phase of a barn repair project in Springfield, Vermont, stabilizing a gorgeous little barn from the early 1800s.

History of this Historic Timber Frame

The vintage timber frame is part of the historic Kirk homestead. We believe it was William Kirk Junior who built this barn. The son of a revolutionary war soldier from Springfield, William purchased the farm in 1809, and most likely built this structure at that time.

In 1834, the land records note that William Kirk mortgaged the farm to a Mr. White for $300. It may have been a tough year for farming, or perhaps William needed cash to work on the second barn on the property, which is attached to the older frame.

The large barn is connected at a perpendicular angle to the smaller old structure. Farmers often sought to create a protected barnyard area for livestock and equipment, and the “L” profile of the attached barns does just that.

The records state that the loan was to be paid back annually over three years in “good salable neat stock or grain.” William must have successfully paid off the mortgage, as the property stayed in the family for a total of 97 years before being sold.

 

In 1864, William sold the farm to his son Aaron. Thirty years later, Aaron conveyed the farm to his younger brother Reuben, a Civil War veteran who had fought in the 10’th Regiment, Vermont Volunteer Company. The property stayed in the family until 1905. Many thanks to the current owners for sharing their careful historical research with us!

A Barn in Need of Repair

While the barn had beautiful stone foundation work, the water had pushed and the frost heaved against the stone and sills, and the joinery of the structure was deeply strained. The stone wall under the gable was collapsing, and four different posts had “torn their trunnels” and dropped down out of the upper beams.

 

3_Corner Post Beam_Green Mountain Timber Frames Vermont

This corner post dropped as the sill beneath it deteriorated, and the pegs broke allowing the tenon to drop out of the mortise.

 

Our Approach to Restoration

Our project was to jack the posts back home again, and to replace the sills. The barn was listing dangerously towards an eve because braces had failed. We used a series of come alongs as we lifted posts in order to coax the wall back towards plumb.

Note the beautiful five-sided ridge beam! Many of the braces had failed, and in this photo we are coaxing towards the western horizon. On the far wall, you can see where one of the posts has dropped.

As we lifted, we were able to feed the tenons home.

We were able to bring this tenon right back into the horizontal timber. Even the siding boards slid back into the grooved channel in the beam where they started out.

The Split Rail Fence

But wait- what about the split rail fence? After posting our last blog about the fencing used as collar ties in Tunbridge, we were surprised and delighted to discover split rail fence pieces used as floor joists in the newer and larger of the Kirk barns!

Old William Kirk was a resourceful fellow. Most likely the original floor joist snapped, and so a nearby rail was conscripted for the purpose.

 

A Barn Rebuilt to Last!

Now that the frame has repaired sills and is stabilized, the terrific crew at Terrigenous Landscape Architecture will re-build the dry laid stone foundation and wall on the gable end. Scott and his team have already installed a drainage system around the exterior of the barns, which will protect the repaired barn complex and stonework from future freeze and thaw cycles.

We look forward to returning to Springfield in the fall after the stone work is accomplished, to continue frame and siding repairs. In the meantime- happy fencing to all you farmers out there!

Reminiscing About a 2011 Barn Restoration

Luke and Matt worked together on a project in 2011 and we’d like to take this opportunity to share it with you. The repairs were done on a small barn on a beautiful property here in our hometown of Middletown Springs, Vermont. The homestead dates from before 1800 and we believe the barn that we worked on was built in 1806.

We repaired the red barn, which sits nestled under the mountain among a collection of vintage barns and corn cribs

The barn had two main structural issues: rotten sills and a rotten upper beam called a top plate that supports the rafter bottoms. We decided to start from the ground up.

The sills were tired from sitting directly on stone for 205 years

We began by using hydraulic jacks to strategically lift the barn up off of the stone foundation. This allowed us access to the sills where they needed work. In our restorations, we use vintage materials for replacement parts whenever possible.

The next photo shows Luke using a chain mortiser to begin cutting to splice in a new piece.

The beginnings of a scarf joint

With the weight of the barn held up on jacks, we were able to cut joinery on a new sill piece and fit it together with the still sound original section of sill.

Here we have used an English scarf joint to add in a new section of sill

One eve wall of the barn was close to grade and the sill was entirely rotten. For this wall, we chose to use Locust wood for the sill replacement.

Locust grows locally and is a remarkable species. As a kid growing up on a Vermont farm, I had the opportunity to work with locust for a long time- at times more cheerfully than others! My father, siblings and I cut many locust fence posts from the woods. We would drive the locust directly into the ground and, because of the nature of the wood, it would last many years even when underground.

In fact, I have stumbled across old, grayed locust fence posts deep in Vermont woods. The old fence posts tell the story of much of Vermont’s land being cleared of forest during the 1800s. Now, the forest land is expanding to take up a larger portion of the state. Locust posts, as well as stone walls, stand sentry in parts of our current woodland to tell the tale and transitions of our farming history.

We copied the joinery from the original sills before installing the new timber

Once we had the barn set back down on repaired sills and had rebuilt the stone foundation, we took a look at the second major issue. What we found was some serious rot caused by a leaky roof at some point in the past. The first roof had been cedar shakes, later replaced by slate.

Folks, we have an issue!

In order to repair the top plate, we first set up a system to jack up and hold the rafters in order to free up space for our repair.

The rafters are supported and we have cut out the rotten section of beam

We used an English scarf joint to make the top plate repair. When we need to replace a section in a barn, we use vintage materials from our inventory in order to get a matching color, tone and hue.

The top plate is repaired and ready to support the roof for another 200 years

Next, we replaced the siding windows and trim on the barn.

Restoring a 30 x 42 Barn Frame – Our Latest Endeavor

Reading this in your email? For easier reading – Click here.

Despite winter’s encroachment here in northern New England, we’ve been hard at work at Green Mountain Timber Frames.

For our most recent project, we have been restoring a beautiful 30×42 foot barn frame from New York state. Built in the 1790s, it is a fine example of a gunstock frame.

img_4220

Look at the handsome grain and joinery of this gunstock oak post

What is a gunstock timber frame?

This means that the upper timbers all come together at the same elevation. It is an incredibly strong method of construction.

img_4239 However, there is a drawback to gunstock frames: it can be challenging to install a second floor because the rafters start at the same elevation as the loft. It is not an issue for storing hay, but can be a challenge when designing a bedroom! The team, which includes a restoration architect, our client and ourselves, figured out a way to install a second floor in this particular barn. We used scarf joints to raise the height of each post, which allowed us to create a 20 foot loft area below the height of the upper horizontals.

Technical challenges of assembling this timber frame

It’s a good thing we love a challenge, because with this frame, (unlike most) we couldn’t make all the changes without assembling the frame. Why? Because of the angled “summer beams”-the large timbers that pick up the weight of the floor joists. (We will get to the reason for the splayed summer beams in a bit.) Doing compound joinery on a 220 year old structure is only possible if you erect that section allowing the joinery to be measured and fitted in place.

Creating the second floor

So how did we solve our little technical problem? We began by erecting half the barn frame behind our shop.

erecting-half-a-timber-frame

This timber frame is predominantly white oak, so we wanted to match the original species of wood. We purchased white oak timbers from Ohio since white oak is hard to find in our area these days. Given the long span of these beams, we had to use 10×12 inch timbers. For the new posts, we used 10×10 inch timbers.

White oak timbers

In order to help the new timber blend in with the old, we used the old method to create an authentic texture: a broad axe and an adze.

img_4186

Here’s a shot of Luke, hewing the new oak beams

Next, we created crooked joinery, because the heavy carrying timbers are splayed, rather than the typical perpendicular or right angles to each other. The only way we could be certain the timbers would join together properly and securely was to fit the timbers in place.

We chopped and chiseled…made templates…and set the 1000 pound timbers in place.

Setting thousand pound timbers

This now creates a second floor that did not exist originally!

But why did we have to angle the carrying timbers? 

To maintain the original ladder we tightened up the two posts carrying the heavy floor girts. The ladder rungs will be set in the close pair of 10×10′ white oak posts. We have not placed the rungs between the posts yet.  That was the least of our problems…………

The end wall will have a 12 foot bay window between those posts.  Along with the owner and architect, we wanted the heavy summer beams, combined with the posts, to frame the large bay window in a fascinating way!

So the owner gets his ladder and his bay window and a very unusual design that makes this particular frame restoration much more interesting.

In order to check new joinery on other sections of the frame, as well as to store it safely until spring, we put the whole barn up and applied a temporary roof.

Here’s the 30×42′ frame tipped up with a temporary roof.

 

Next steps in the restoration process

Our next step is to set all the hand hewn floor joists into these heavy carrying timbers using traditional joist pockets. But, for the moment, we have moved on to another outside project. With this structure standing and roofed for the winter, we will have plenty of opportunities to return to this task when it is raining or snowing! In the spring, we will label everything, disassemble, and ship the frame to its final location. It will be ready to stand strong and true for another 220 years.

Note the incredibly wide original siding boards!

Stay tuned for a story on our next project: a timber-framed porch. We better get going on it, as we received our first heavy snowfall of the year this past week!

After carefully skinned the old timbered house, we took it apart, timber by timber, making sure to label meticulously along the way. Over the next two months, we will professionally restore the timbers, before reassembling the frame in New York. Look forward to the results in late summer, when we re-erect these historic beams for another 235 years! In the mean time, we hope you will stay tuned with our blog!

Repairing a Silo – without letting her tip!

I recently repaired this wooden silo in Danby, Vermont. It was originally built in the 1850s. While the silo is not currently being used, the owner wanted to maintain the look and feel of his New England barn home and asked me to repair the vintage wooden structure. It had originally been used to store silage for cattle.

The silo had a 38-foot circumference and most of the bottom boards around the base were rotten. I was hired to fix this tall task!

Rotting boards along base of silo

Luckily, only four inches of the base wood was rotted. To restore the silo, we cut seven inches up to get back into solid wood. The original silo boards were either spruce or cypress, but I used locust wood for the repair. Locust is plentiful in our area and is our natural “pressure treated” wood species, meaning it is very resistant to moisture rotting the wood fibers.

We had the new pieces of wood custom sawn to the exact dimensions we needed to ensure they would match the size of the original silo boards.

New boards on silo

In order to repair the frame, we first built an internal frame on the inside of the silo. This frame enabled us to screw the short pieces of locust wood back into something solid. This system ensures the integrity of the repair and will help the silo stand tall for decades to come.

Support system seen from inside of silo

I used a three-tier system, shown below. The first tier board was fastened to the concrete floor at the base of the silo. The second board was for fastening the new seven inch locust replacement silo pieces.

In the third level,  I attached the original section of the silo board. With these three levels in place, the silo boards are now secure and there is plenty of space for air to circulate inside the silo. This air circulation will help prevent rot in the future.

Prototype of interior fastener

The silo’s wooden walls are two inches thick, so I could not use my preferred routing method to duplicate the original tongue and groove boards Instead, I used three table saws to carve the tongue and groove system for the replacement pieces. Tongue and groove joints allow two flat pieces of wood to be joined together to make a single flat surface. It’s a wonderful system that ties all the boards together.

We cut one three-foot section at a time, secured them to the internal framing, and then moved on to the next three-foot section. There are twelve sections in all. Nine feet of the original boards were still solid and did not need restoration.

I feel good about the repairs we did to this beautiful historic property, and I believe this system will hold up another 150 years. We left some locust boards in the silo, so if another repair is needed in the next 50 years or so – they are ready to go! That untouched original 9 feet of silo might need repair in 30 years!

In working on this silo project, I was once again grateful to live in New England and to work together with people – like the owner of this silo – who value history and are willing to invest in ensuring that old barns and silos remain part of the landscape for generations to come.  We all benefit from their passion to preserve our heritage.
