It's been discussed in the Architectural realm for years.

Here's the backdrop....For the past 20yrs I've ran a residential design/build company. 10yrs ago I was able to get into REI and now have 6 properties total (2 personally (1-ABNB / 1-SFH LTR)/ 4 (LTRs) in a LLC with a partner), and manage 2 additional properties as the property manager.  2yrs ago I decided to drop the building side of design/build, and now I just do architectural design and REI.

We also do the design of them, both architectural and interior design.

Definitely need to talk to some local GCs, and share with them exactly what you are looking to build.In my area, you'll have GC's tell you they can build ground up single family for anywhere from $200/SF to $600/SF depending on the architecture, quality of finishes, and lot conditions.

i would like to help with the architectural design.

After three years practicing architecture, I've decided to pivot into the business side of things.

It seems like a lot bigger DIY job than Vinyl.That little place could really use some curb appeal.I took the pic above and floated some curb appeal things onto it that I'd think about if it were mine.A new door opening on the right, double the window size, and a more modern color scheme, a little wider siding, etc...Which is a lot more money than just residing in vinyl.I used GIMP to make this (quickly), and not an architectural program which is why it looks a little cartoonish.Good Luck!
