Using SIPS on the roof brings with it the opportunity to have exposed beams. In this case we really had fun with all of the crazy angles and shadows that were simply a natural consequence of trying to make as good of use of the space as possible. #exposedbeams

Today I had the pleasure of speaking to Prof. White's management class at our 504 Jefferson addition. Turns out it was their last class of the year, and for the seniors, their last class at Luther! Given the circumstances, they were remarkably attentive and curious. Thank you to MGT 371, and congratulations to ALL students wrapping up a very challenging and unique year

I love seeing old houses just going with the flow. Now I doubt that these windows are operable, but they could be. Now try to do that with a clad door and window. By the time you square that parallelogram, you'd probably lose a quarter of the glass. Kudos to the city of Waterloo for preserving this house.

Late last year we finished up a large window restoration project at the Louden Machinery Factory in Fairfield Iowa. Louden manufactured and sold farming equipment, including Barn plans, all over the Midwest between 1868 and 1956. The factory had previously been converted to housing, and received a major makeover last year as part of the work we were doing. About a third of the windows were restored, mostly on the first floor. The rest of the windows were replaced. See if you can spot the difference.#iowaarchitecture #thisplacematters #iowahistory

Trust but Verify. Especially when you're asking your contractor to tie into an existing home. It's not enough to use all of the latest and greatest in energy efficient products, but leave gaping holes in the shell and where the buildings meet. Thank goodness we have the @winneshiekenergydistrict to assist in verification. #buildingscience

Between the storm window and the primary window, that's 24 panes of glass. They're are a ton of work, but they sure look good when they're well-maintained. Especially against that freshly pointed brick
