Can you extend an existing metal building?
Usually, yes. Most pre-engineered buildings can be extended at an endwall by adding new bays. The new frames, roof slope and panel profile have to match the existing building, and the original endwall often gets converted to an interior frame. We start by identifying the manufacturer, or measuring the frames when the original drawings are lost, and we order engineered components to match.
Adding a lean-to along a sidewall is often the cheapest way to add covered space. The lean-to’s loads have to be checked against the existing columns, which is why we engineer it rather than bolting something on.
