Skaters on Haumerson's PondThe Friends of Haumerson’s Pond have assigned terms associated with Timber Frame construction to our levels of sponsorship in Phase I of the overall park project. These terms depict specific components used in the construction of a timber frame structure. Donors will be eternally identified within the Warming House/Trail Head on those structural members.

Top Plate

The Top Plate is the major horizontal timber that supports the base of the roof system. There are two Top Plates in the structure located on the very top of the walls that bear the weight of the roof. The Top Plate binds together the structure from one end to the other. It is our highest level of sponsorship identifying any donations that are $25,000 or more.

Tie Beam

The Tie Beam is a key horizontal timber that binds the building together from side to side. It prevents the thrust of the roof from spreading the walls apart. There will be four Tie Beams in our structure that will bear the names of those who donate $10,000 – $24,999.
Support Post- The Support Post is a major vertical timber that will bear the weight of the structure. The Top Plates and Tie Beams tie into the support posts using mortise and tenon joints to form the structure of the building. Support Post sponsors will be recognized for donations from $5000 – $9999.


The Girt is a horizontal timber that spans the distance between support posts. Its function is to provide a nailer for the vertical sheathing that will protect the structure from the elements. It is the basic component that will give the walls their strength. Donations of $1000 to $4999 will be recognized upon the Girts.

Corner Brace

The Corner Brace is a diagonal timber that gives the building its strength. The strength of a timber frame is dependent upon the corner braces to stand firm against the wind. It allows the building to be flexible but not break. Sponsorship of $500 – to $999 will be awarded recognition on a corner brace.


The word Trunnel is an olde english term that means “tree nail” or “wooden peg”. These wooden pegs are used to bind the mortise and tenon joints together. Measuring only 8” x 1” the Trunnel is the smallest component in a timber frame but also the most prolific. The trunnel is used in every joint in the building, binding the structure together. Donations of $1 – $499 will be recognized within the building at the Trunnel sponsorship level.
