Every plan is assembled from the Biotekt core system: 4.64 × 4.64 m arch, vault and crossvault spaces joined through 58 cm structural panel-junction cavities, extendable in 29 cm panel increments. Add plans to your site to build a home or a whole village — then drag buildings into place, open or glaze any arch, extend in 29 cm steps, or lift a space onto a stone podium storey. The estimate updates live. * Plans with a Biotekt catalog line carry the official catalog floor area, rooms and 2018 USD MSRP for the biocomposite shell + construction documents; "from" prices are live Bioshel panel-kit estimates for the plan as drawn here.
