This contemporary mountain ADU (Accessory Dwelling Unit) blends modern architecture with the warmth and practicality often associated with mountain-style homes. Designed for compact yet comfortable living, the home features a total structure of 1,525 square feet, with the main living area located on the second floor above a spacious two-car garage. With thoughtful design elements and smart use of space, this plan is ideal for mountain properties, guest homes, rental units, or backyard ADUs.
The home's layout maximizes functionality by placing the primary living areas on the second floor. The 960-square-foot second level contains the kitchen, family room, master suite, and essential living spaces, allowing for privacy and elevated views. This design is especially beneficial for mountain or scenic locations where homeowners want to take advantage of the surrounding landscape.
The first level is dedicated primarily to the 960-square-foot side-load garage, which offers generous room for two vehicles along with additional storage space for outdoor gear, tools, or seasonal items. The side garage entry maintains a clean and modern front elevation while improving accessibility for narrow lots or angled driveways.
Inside the second-floor living area, an open-concept layout creates a seamless connection between the kitchen, family room, and dining space. This arrangement enhances natural light and makes the home feel more spacious despite its compact footprint.
The kitchen serves as the heart of the home and includes a large kitchen island with an eating bar—perfect for casual meals, entertaining guests, or everyday family gatherings. A walk-in pantry ensures there is plenty of storage for groceries and kitchen essentials, helping keep the space organized and efficient.
The adjoining keeping or family room provides a comfortable gathering area where residents can relax, watch movies, or enjoy quiet evenings at home. The open design encourages easy conversation between the kitchen and living spaces, making it ideal for modern lifestyles.
One of the standout features of this contemporary mountain ADU is its outdoor living areas. A side porch measuring 136 square feet provides a cozy outdoor retreat for morning coffee or evening relaxation. Meanwhile, the 429-square-foot balcony expands the living area outdoors, offering a perfect spot for enjoying mountain views, fresh air, or small gatherings with friends and family.
These outdoor spaces enhance the connection between indoor and outdoor living—an essential element in mountain-inspired home design.
The second floor also includes a comfortable master suite designed for privacy and convenience. The bedroom features a walk-in closet and direct access to a private master bathroom equipped with a double vanity sink, making daily routines more efficient.
Having the master suite on the upper floor ensures quiet separation from the garage and any activity below, creating a peaceful retreat for homeowners.
Despite its compact footprint, the home includes several practical features that support everyday living. A second-floor laundry area adds convenience by placing laundry facilities close to the bedroom. The 10-foot ceiling height on the first floor contributes to an open and airy feeling, while the 2x6 wall framing enhances structural durability and energy efficiency.
The home is built on a slab foundation and features a 3.5:12 roof pitch, creating a sleek contemporary profile that complements modern mountain architecture.
With a 32-foot width, 30-foot depth, and a total building height of 29 feet 8 inches, this design fits well on compact properties while still offering generous living space. Whether used as a guest house, rental unit, studio residence, or private retreat, this contemporary mountain ADU delivers comfort, style, and versatility in a beautifully efficient design.
The construction drawings will include detailed, dimensioned floor plans, exterior elevations, roof plan, foundation plan, basic electrical layout, cross-section(s), foundation plan, and other general specifications. Some plans will include interior cabinet layouts.

All house plans sold by Archival Designs have been designed to comply with the International Residential Code (IRC) and to the local codes in the area where the designer resides or where the house was built.
All house plans are designed to meet or exceed the national building standards required by the International Residential Code (IRC). Due to differences in climate and geography throughout North America, every city, local municipality and county has unique building codes and regulations that must be followed to obtain a building permit. Prior to purchasing a set of house plans, we recommend that you meet with your local building officials in order to determine the building requirements for your area. It is the responsibility of the purchaser(s) and/or builder to ensure that the structure is constructed to meet the codes of their local area.
Important Note:
House plans do not come stamped or signed by an architect or engineer. Additionally, house plans typically will not include structural engineering notes/calculations. Please check with your local building officials to determine if a stamp is required. If required, the building department will only accept a stamp from a licensed professional in the state where the home will be built.
Depending on your city, county, and state building requirements, house plans may need to be reviewed by a local licensed architect or engineer for structural details and code standards before construction begins. This is particularly true in coastal areas and those facing seismic events, extreme winds, and heavy snow. If you are building in any of these areas, a licensed structural engineer will likely be needed to provide the necessary calculations and additional drawings. We authorize the use of our plans conditioned on your obligation and agreement to strictly comply with all local building codes, ordinances, regulations, and requirements, including permits and inspections at the time of and during construction. We recommend checking with your local building department for the most current requirements. The purchaser(s) and/or builder are responsible for additional expenses incurred through meeting municipality requirements or other requirements for construction.
Our foundation plans have been designed for universal conditions and may need to be adjusted to fit your specific site conditions. The foundation should be modified by a local structural engineer to comply with soil testing laboratory findings and local building requirements.
Our house plans will include schematic electrical drawings; however, circuiting or wire sizing will not be included. Your electrical subcontractor will typically provide these drawings.
HVAC and plumbing drawings are not included. Your mechanical and plumbing subcontractors will determine the best layout for your site. Local HVAC codes, climatic requirements and commonly used systems vary throughout the country. The direction of how water flow will enter the home vary from case to case. For this reason, it is impossible to provide universal plans.
