From the architect. The Port Elizabeth Opera House was originally designed by local architect George William Smith and opened its doors on 1 December 1892. Four additions followed - the first in 1911, followed by extensions in 1927, 1934 and 1985. The current Opera House is thus made up of five distinct parts which throughout the years have merged into a single building of a distinct neo-classical style. At present the Opera House is the oldest theatre in Africa and also the oldest operating theatre in the Southern hemisphere.

The design of industrial architecture presents a considerable challenge, since certain factors such as the industrial workflow and the conditions for the workers and machinery provide the guidelines for the development of the project. However, in many cases, industrial projects are designed without further exploration in terms of materials or construction systems, aiming simply to comply with regulations. This month we want to highlight the Organic Farm in Tangshan by Chinese firm ARCHSTUDIO, a project in which an interesting structural and conceptual exploration results in a new industrial architectural intention, and which also generates new public spaces to promote a relationship with the nearby community through the construction.

The James River House was designed as a place for three young boys. It is a place where they can grow and learn from their surroundings - experience mud, moths, flowing water, and the changing light of the seasons; a place that would allow for many gatherings of all the people who love them. Three volumes hover above a bluff alongside a bend in the James River, arranged loosely and lightly on the land like a scattered group of stones around a campfire. As a visitor slips between the volumes, the house opens up to light and river views and the fully enveloping woods. The quiet yet open interior is built around a large and flexible gathering space that can be intimate, expansive, interior, or exterior. Flanked by sleeping quarters, this central living area is at once hearth, tree house, and dining hall and is the nexus of activity for the family and the three boys who fill the house with light and motion.
