This article documents the design, construction, cost, and productive performance of the Little Legon Mushroom (LLM) Farm, a small-scale oyster mushroom (Pleurotus ostreatus) growing facility established in Little Legon, Greater Accra, Ghana. The farm was deliberately constructed around existing Leucaena leucocephala (white lead) trees, incorporating living vegetation into the structural and environmental design of the growing house — a strategy that simultaneously eliminates structural timber costs, provides natural shade, improves microclimate conditions, and enhances the aesthetic character of the facility. The article presents the complete construction process, itemised material costs, and a comparative materials analysis contrasting conventional-timber and tree-integrated construction approaches. It develops a detailed financial analysis at current market prices of GH₵55–75 (~5. 1–6. 9) per kilogram of fresh oyster mushrooms, demonstrating that the LLM facility — producing 60–85 kg per harvest cycle with four to five cycles per year — generates annual gross revenue of GH₵13, 200–21, 250 (~1, 214–1, 955) with a conservative net return that compares favourably with land-based agricultural investments of comparable capital requirement. The article further addresses the farm's role in household nutrition, its integration with animal husbandry through by-product feed for poultry, birds, and rabbits maintained on-site, and its employment-creation potential at two persons per facility. The LLM Farm is explicitly framed as an experiment in replication: the article presents a scalable model — from the household single-unit growing house to village-cluster enterprise networks — and identifies the research gaps that must be addressed to realise mushroom cultivation's full potential as a food security and income-generation intervention in sub-Saharan Africa.
