>My fiance and I are in love with this plan, but struggling to figure out if it would be affordable. Find a GC and ask him that question. No way for anyone to know frost depth @ your location. >The two major costs that we foresee are the cost of concrete, as this house has a large footprint, and the steel roof. It will not be the cost of concrete - it will be the cost of foundation [LABOR]. No one can tell based on little information you provided. Cost could also depend on a soil type. Expensive soils could do a number on your budget. Steel roof? or aluminum - again greatly depend on the local rates. Metal roofing itself is not that expensive [$90s/100 sq ft]. Install - another issue.

We searched and searched and found this thread useful so here are a couple of tips...take or leave them... Moved the kitchen wall back 1' into porch to expand great room/kitchen. Really you could do 2' and still have a very large back porch. 10' ceiling won't allow mechanical to go in winged attic. We built two very large closets in the loft, one for mechanical and the other storage. The loft is still huge. Don't waste money on a study set or plans. Ours had to be engineered and we took concept and customized. Took side windows out of bedroom 2 and replaced with huge closet. Tweaked that and laundry room entry for our needs. Modified laundry room to make larger and have a 1/2 bath and big utility sink. Tankless water heater saved room as well. Master bath freestanding tub 57" will fit with no mini stub wall there. Master shower is plenty big with a corner bench and no door of any kind - minimal splashing. The island is centerpiece and took two pieces of stone but matched perfect with no visible seam. Make sure your cabinet person puts storage underneath bar hangover. These two slabs of stone provided all we needed for kitchen, master bath, and coffee bar. We use closet on east side of great room as the pantry and took out the west side and made a really nice coffee bar with upper and lower cabinets. Master bedroom may be small for a lot of people but great for us - all clothes and clutter lives in walk in closets. We did move north bedroom wall in 6" to squeeze a little more room. Fits a queen with beside tables fine but a king or california king would be tight and stump your toe to walkaround twenty times a day. Bath 2 should have put a pocket door into tub/toilet area. Swinging door is pointless and ended up being tight. Hindsight would move that interior wall out into vanity area 1'. Fits our 48" freestanding vanity amply as is with room to spare. We don't use the dining area or have a chandelier. We put a 8' diameter ceiling fan on a nice down rod to flush with loft floor over den and it is perfect. Can lights throughout house with dimmers. Will have outdoor dining and six stools at bar. Pulled front porch in from 12' to 10' for cost. Still is huge and has complete shade in high noon sun as we oriented our house north and south. Cantilever the loft stairs to float (shown below was field changed).

Well...this house is designed with a strong exterior-interior linear concept as the fundamental basis for design. While some minor exterior and interior modifications may be possible, there are limits to what modifications may be made without losing the all important concept. If the concept doesn't work for someone, the best strategy is to look for another house designed with a concept which is a better fit.

We built this house. Finished the build in February 2020. We did a lot of the work ourselves. For example , grading, excavating, drainage, flooring, painting, closets , some trim/finish work, etc. We still had to pay the builder over 300k to do his part. We live in Maryland, 45 minutes outside DC. Love the house and the porches.
