# 3d-Printed Vaulted Dwelling Underground House of the Future Reinvents Cave Home with Brick Vaults By Amy Duong | Published 2026-03-02 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/underground-house-of-the-future References: [dezeen](https://www.dezeen.com/2026/03/02/underground-house-of-the-future-reinvents-chinese-cave-home-with-brick-vaults-and-3d-printing/)  Underground House of the Future is a residential project that reimagines the traditional Chinese yaodong cave dwelling through the use of 3D-printed brick vaults and engineered earth construction. The design excavates into the site to create a semi-sunken plan that retains the thermal and spatial logic of [earth-sheltered homes](https://www.trendhunter.com/trends/house-of-four-soils) common on the Loess Plateau, while introducing a series of printed brick vaults that define the main living spaces. The vaults express a contemporary reinterpretation of historic arched forms, pairing tectonic brickwork with digitally fabricated precision that supports both structural stability and spatial clarity. Walls and vaults are produced on-site using [additive manufacturing techniques](https://www.trendhunter.com/trends/qr3d) that layer bespoke masonry components, reducing material waste and enabling complex, curving geometries without conventional formwork. Interior volumes are organised around a sequence of vaulted chambers that open onto landscaped courtyards and light wells, connecting subterranean spaces with exterior terrain.
