Locally owned by its employees HPM Building Supply has four locations on the Big Island (Hilo, Keaau, Kona & Waimea), one on Oahu (Kapolei), and two on Kauai (Lawai and Kapaa). After merging with Miyake Concrete Accessories in 2020, HPM gained four additional locations on Maui (Wailuku, Kihei, Makawao, & Lahaina). Since starting over 100 years ago as a small, family-owned Hilo lumber mill, HPM Building Supply has grown into a one-stop-shop for industry professionals and everyday homeowners. HPM manufactures pre-engineered trusses and wall-panels, metal roofing, packaged homes, and pre-hung doors; and provides in-house treated lumber, building supplies, home planning, and custom metal roofing across the state.
