A steel frame annex is a self-contained modular living space that can be attached to your home or built as a detached stand-alone unit. It typically includes a bedroom, kitchen, bathroom, and living area, offering all the comforts of an independent home. Unlike basic extensions, annexes are built to function as fully separate living quarters, making them perfect for families with changing needs, elderly parents, grown-up children, or tenants. These annexes are manufactured using a robust steel frame structure, ensuring exceptional stability, durability, and long-term performance.
