The interior of a Mission, nowadays, is similar to that of a Tuscan-style house which means, European in flavor. Old world European, to be exact. Arched doorways, exposed beams, and large windows capture the feel of a villa. The rooms are wide open to mimic outdoor space, and they tend to be painted in bright, cheery colors these days. The interior is based on minimalism which means there aren t many embellishments to be found. There is little information available as to the interior of Spanish Mission housing, so nowadays, it s pretty much a mixture of Arts & Crafts and Spanish Revival.
