‘Joglo’ is the architectural vernacular for Javanese structures. Built to last, they are made of teak wood, which is beautiful as well as an enduring outdoor material. They are constructed without nails or screws using a variety of joinery techniques including ‘Mortise and Tenon’, 'Half-Lap' and 'Tongue and Groove'. The four tallest columns or ‘King Posts’ form the central part of the house or pavilion. Consecutively shorter columns extend outward to carry the rest of the sloping roof creating a vaulted central area. It relies on this tall main structure for support rather than the bearing walls of western styles which would inhibit crucial, natural ventilation.
