That's too context-specific to answer without a whole lot more questions. Plus, if we're actually talking about code, physical metaphors break down anyhow. First-cut answer is "move bathrooms closer"/"make the hallway bigger" but one must also ask the question, "How did this mismatch arise in the first place?" Anything is possible, especially in software; the hallway may in fact be adequate and it's everything else that is grossly overspec'ed... or in fact, you might have ended up with a poorly-designed dining room for 100 people because that's all the previous guy knew how to build, when in fact you need a stadium for 100,000 people. (I've been there before.)
