Kikuchi & Associates That is a Bloodgood Japanese Maple (with a little bit of a Jasmine vine growing into its top canopy), or Acer palmatum "Bloodgood". It has reddish/purple delicate foliage throughout the spring, summer and is decidous in the fall/winter. A beautiful tree, especially when in a multi-trunk form.
Kikuchi & Associates The arbor spans are about 12' and 18', made with double 4x10 #1 grade cedar beams.
The connection design with the post and beams are critical in order to provide proper shear for the structure. Make sure you consult with a structural engineer prior to construction of such a structure.
like this pergola and fireplace, I like the proportions but overall it's too big and don't want white. but like width of fireplace and walls next to it and like the pergola like brick on one side and end too
