For a simple home or renovation, is an architect really necessary?

It depends what you mean by simple. Even a straightforward project involves decisions about orientation, light, ventilation, materials, and how rooms connect to each other. Those decisions affect how the building feels to live in every single day. You don't need an architect for everything, and we'll tell you honestly if we think your project doesn't warrant one. But for most people who care about how their home works and feels, having someone whose entire job is to think carefully about space is worth it.
