Project Basics

Heated/cooled interior square footage to be built.
Rural/smaller markets lean lower; big coastal cities lean higher.

Tip: Not sure? Leave at 1.00 and adjust after you calculate.
Affects interior & allowance buckets.
Typical planning allowance: 5–15%.
If unchecked, sitework/rough grading is assumed by owner/others.
Width of the dome at the base, in feet (sanity check only).

Design & Envelope

How much of the shell surface is windows/doors.
Count of utility/garage domes (no interiors/MEP/glazing).

Site & Systems

Steeper grades, rock, or tricky access increase costs.
More zones, smart systems, or specialty equipment increase costs.
Enable if a new driveway is needed. Typical rural drives are 50–150 ft.

Optional Systems

Other Site Factors

Remote sites add logistics for crews, materials, and equipment.
If reliable power isn’t available for Airform inflation, choose generator.
