Let's Talk T-Arrow

1.300–400 sq ft ADU floor plans – for studios, home offices, or guest suites

2.500–600 sq ft floor plans – ideal for 1-bedroom units with open kitchens

3.800 sq ft ADU floor plans – our most popular size for rentals or extended family

4.900–1,000 sq ft layouts – perfect for 2–3 bedroom units with full kitchens and baths

5.1,200 sq ft ADU floor plans – the maximum allowed in many California cities, perfect for multi-bedroom layouts or comfortable long-term living.
