Custom Accessory Dwelling Unit Design
We focus on custom ADU design that fits your lifestyle and property specifics in Dos Vientos Ranch's Mediterranean climate, where mild winters and warm, dry summers create ideal year-round living conditions. Our team works closely with clients to develop plans that maximize space, natural light, and energy efficiency while considering the area's wildfire history, including evacuations in 2013 and 2018.
Our designs reflect your needs, whether you want a granny flat construction or an in-law suite addition. By integrating modern amenities and flexible layouts, we create units that are functional and comfortable for daily living or rental purposes, capitalizing on the community's appeal to relocators and multigenerational families. We utilize industry-leading design software and collaborate with experienced architects to ensure each project meets the highest standards for both aesthetic appeal and functional efficiency.
Detached and Attached ADU Solutions
We specialize in both detached ADU construction services and attached units, tailoring the structure to your property's layout in this neighborhood where typical lots are relatively small but housing ranges from $700,000 townhomes to $4 million custom estates. Detached ADUs offer privacy and independence and are ideal when you have sufficient backyard space to accommodate separate structures while maintaining proper setbacks.
Attached ADUs work well for expanding your home footprint or creating closer quarters for family members. Our team focuses on seamless connections to existing homes while maintaining the curb appeal that has made Dos Vientos a desirable address since major development began in 1998. We source materials from reputable suppliers and ensure all construction meets or exceeds local building standards, using quality lumber, roofing materials, and exterior finishes that withstand Southern California weather conditions.
Garage Conversion and Basement Remodels
Transforming existing space is a cost-effective alternative to new construction in this community where property values are higher than other Newbury Park neighborhoods. We handle garage conversion ADU projects, turning underused areas into livable units with proper insulation, plumbing, and electrical work designed for the local climate. Our conversion services include structural assessments to ensure existing foundations and framing can support residential use.
Our basement ADU remodel services improve utility and comply with safety and building codes. We emphasize making these spaces bright and inviting through design improvements and structural modifications, particularly important given the community's elevation and unique topography. Professional waterproofing and moisture control systems are essential components of our basement conversions, ensuring long-term durability and comfort.
Prefab Backyard ADUs
For faster installation, we offer prefab backyard ADU homes that maintain high quality standards while accommodating the busy lifestyles of Dos Vientos residents, many of whom are scientists and engineers. Prefabricated units reduce onsite construction time while providing durable, customizable options manufactured to precise specifications in controlled environments.
These units are ideal if you need a quick build without sacrificing design or function. Our prefab options serve as efficient solutions suitable for rental income or extended family use with minimal disruption to your property in this quiet, family-friendly neighborhood. We partner with established prefab manufacturers who use quality materials and proven construction techniques, ensuring these units meet the same standards as traditional site-built construction.
ADU Planning, Permitting, and Design Visualization
We handle every aspect of ADU development from initial design concepts to securing permits through Thousand Oaks City Council processes. Our experience navigating the approval procedures that once took 21 years for the original Dos Vientos development ensures compliance with local codes while creating efficient, livable spaces.
ADU Floor Plans and Layouts
We provide customized floor plans that optimize use of limited space, considering the smaller lot sizes typical in Dos Vientos Ranch. Whether it's a studio ADU, one-bedroom layout, or two-story design, our plans focus on functionality and comfort while maximizing views of the surrounding Santa Monica Mountains. Our design team has extensive experience creating efficient layouts that feel spacious despite compact footprints.
Small space ADU floor plans emphasize open layouts and multipurpose areas. We balance living, cooking, and sleeping zones to maximize usability while incorporating features that take advantage of the area's abundant sunshine and mild climate. Strategic window placement and interior design elements create the illusion of larger spaces while maintaining practical functionality for daily living.
Blueprint Drafting and Permit Services
Our team prepares accurate, detailed blueprints tailored to meet Thousand Oaks and Ventura County standards. We submit these for building permits, reducing delays caused by incomplete paperwork or code violations in this jurisdiction that carefully manages development to preserve the community's character. Our drafting services utilize computer-aided design technology to produce precise, professional-quality drawings.
We handle the entire permitting process, including coordination with local building departments, addressing feedback from site inspection services, and ensuring adherence to California ADU building codes. These permit services ease the complexity of construction approvals and keep your project on schedule. Our established relationships with local officials and thorough understanding of permit requirements minimize delays and complications.
3D Project Visualization
We use advanced 3D modeling to create realistic views of your ADU before construction begins, allowing you to visualize how the unit will integrate with the existing landscape and mountain views. This technology helps clients make informed decisions about materials, colors, and design elements before construction begins, preventing costly changes during the building process.
Visualization helps in making decisions about interior design and material selection, structural elements like staircases or lofts, and outdoor integration that complements the natural beauty of Dos Vientos Open Space. Our visualization services include virtual walkthroughs that provide comprehensive understanding of spatial relationships and design flow.
