Work To Be Done
All 110 year old ship lap siding will be removed from this wall.
Replace two sash windows and section of wall with a new 8.5' Mulled window unit.
Replace a third sash window with a new 30" window unit.
New Hardie Trim around all sides of both windows (using Hardie 'flat tabs'.)
Install Hardie 4'x 8' panel on the front wall, snugged up to the trim.
From inside - re-insulate and sheetrock affected wall space.
Structural Engineering for Large Opening
A 10' Glue-Lam beam and 4x4 support posts will carry the roof/rafter load above the window opening. This ample opening will allow for esthetic 'centering' of the window.
Framing and Headers for new windows - not perfectly drawn to scale!
All "Jack" Studs (Trimmer Studs?), to be placed by contractor.
Rough framing sheathed with 1/2" plywood.
Tyvek wrap (or equiv).
Window installed in opening.
Dreaded Inspection!
Details of Foundation & Structural Members
Drawing below features 4x4 supports for the header, 4x4 blocking between the floor and foundation member. The sill 'plates' set on cinder block wall in 1979 are 4x6".

What nailing plates or other brackets should tie header to support 4x4's?
