Xanadu — Detached ADU
About this design
This contemporary ADU blends naturally into any New York City backyard with a clean, neutral façade designed to complement a wide range of existing homes. Its refined silhouette and understated character create a modern yet welcoming presence. Inside, the design continues with a contemporary feel enhanced by a subtle splash of sage, adding warmth and individuality. The layout is carefully planned to maximize living space by situating the rooms along one side. Together, these elements create a thoughtfully designed dwelling that balances refinement with versatility. Pre-approved ADU design from New York City's “ADU for You” Pre-Approved Plan Library (NYC Department of Housing Preservation and Development). Designed by BEAM Architects. The pre-approved plan set is obtained from the design professional who owns it; a site-specific review and filing with the NYC Department of Buildings is still required before construction.

Jurisdiction
Some West LA and Studio City pockets are unincorporated LA County. Confirm your jurisdiction with the local building department if you are near a boundary.
Estimated Build Cost Range
Based on square footage and regional construction averages
This range is a speculative estimate based on typical LA-area construction costs ($350–$600/sqft) and the plan's square footage. It does not account for site conditions, permitting fees, utility connections, or material selections. Actual costs must be validated with a licensed general contractor or the plan's architect before making any financial decisions.

Financing Your Build
Most homeowners finance ADU construction rather than paying cash. These are the common routes — A-du is building lending partnerships to connect you directly.
Illustration only, assuming a 20-year fixed loan at 8.5% APR on the estimated build-cost midpoint. Your rate, term, and eligibility depend on the lender and your finances. This is not an offer of credit; financing is provided by third-party lenders, subject to their approval.
Renovation & ADU construction loans
Lenders that underwrite on your home’s value after the ADU is built — often the best fit when current equity doesn’t cover the build.
Home equity (HELOC / home equity loan)
For owners with substantial equity, a line of credit against the home is typically the simplest and fastest route to fund construction.
Grants & public programs
California periodically funds ADU grant programs (e.g. the CalHFA ADU Grant for predevelopment costs, when funded). Worth checking before you borrow.
