About Two Sails Domus

Duo Vela est domus maritima duabus generationibus familiae destinata. Aedificium ligneum duarum contignationum in Okayama, Iaponia, stat, cuius area aedificata ducentorum quinquaginta metrorum quadratorum est in solo octingentorum metrorum quadratorum. Forma tecti velum navis revocat atque lucem naturalem aurasque marinas in interiora ducere iuvat. Spatia habitandi in zonas septentrionalem et meridianam divisa sunt, ut utraque generatio suam ipsius secretam vitam servet. Porticus tecta duas zonas coniungit et transitum etiam diebus pluviis praebet. Parietes exteriores metallo durabili vestiti sunt, quod corrosioni ab aere marino resistit.
