Building an Attic Loft with a Low Pitch Roof (Approximately 5:12)
I'd say bad idea &amp; keep looking at other houses. Go look at it again with a tape measure. But, the only thing I might consider is putting the utilities up there to gain more user-friendly space on the main floor. Get rid of closets to use floor to ceiling cabinetry instead &amp; store more up in the attic. Maybe a garage or porch can be abandoned &amp; converted to real square footage.

The issue is structural framing &amp; of course roof pitch. It may be stoop worthy but not stand-up worthy &amp; therefore would not ever constitute a legal room of any kind. Typically, the ceiling has to have a minimum peak of 7-feet &amp; you may only have a 3-foot wide section of anything even close to that. Depending on joist height, insulation, rafter depth, collar ties &amp; ridge beam. If any wood has to come out, the plan fails instantly &amp; should not be attempted.

However, if it's wide open &amp; you're thinking it'll just be an office type use where you're seated the majority of the time, then it may work for you. Though, I'd opt for more insulation &amp; hanging utilities from the rafters to then use it as just a crawlspace sort of storage area.
