Not every activity belongs in a beautiful family room.
Some things make dust, noise, smells, grease, or mess.
Give them somewhere to happen.
Cars, woodworking, gardening, fishing, bicycles, golf, crafts, painting, repairs, and hobbies all have equipment.
If the garage has to absorb all of it plus cars and storage, the cars usually lose.
Maybe you need a dedicated workshop bay, an exterior-access utility room, or a durable flex area.
Workshops may need extra electrical circuits, stronger lighting, ventilation, water, compressed air, floor drains, or durable flooring.
If you already know you have a hobby, build for it.
That is one of the reasons to build custom in the first place.
Your house should accommodate the unusual parts of your life, not force them into a generic closet.
