01. Pre-Design

This is where we get on a first name basis. Our team of architects collaborates with you to understand your hillside project vision and goals, while we verify and navigate the unique legal requirements for building on sloped terrain.

02. Design

This is the good stuff. With your ideas and our hillside design expertise, our team puts together several design options that work with the natural slope. We explore floor plans and look at renderings that maximize your hillside views in 3D.

03. Permits

At this point, your hillside design is ready to be submitted to your local jurisdiction to obtain necessary building permits. We can lead this effort, or can assist you in navigating the specific requirements for hillside construction.

04. Construction

Lastly, we provide you with construction drawings, detailed to address the complexities of hillside building that can be given to a general contractor. We can help vet builders experienced with slope construction and coordinate during the build process.

At Refine Design Architecture, we believe that building or renovating a hillside home requires specialized expertise and isn't a "one size fits all" process.

What is the hillside home architect process?

Our hillside home process follows a proven path: idea generation that considers slope and views → design that works with natural topography → secure funding → permit approval for hillside construction → find a builder experienced with slope building and start construction. Each phase addresses the unique opportunities and challenges that come with hillside sites, from maximizing dramatic views to managing proper drainage and foundation requirements.

Do I need a licensed architect for my hillside home?

In Washington State a licensed architect isn't always required by law, but is highly recommended for hillside projects due to their complexity. Hillside homes involve unique structural, drainage, and foundation considerations that benefit from professional architectural expertise. A licensed architect ensures your hillside design meets all code requirements while maximizing the site's potential. The investment in professional design pays dividends in both safety and the quality of your hillside living experience.

What does hillside home construction cost?

Hillside construction costs vary widely based on the slope's steepness, soil conditions, access challenges, and design complexity. Factors like specialized foundation work, retaining walls, and site access can influence the budget significantly. The scope of work, material selections, and desired finishes also impact costs considerably. We help clients understand these variables early in the design process to make informed decisions that align with their budget and vision.

How long does a hillside home project take?

Hillside home projects typically require 3-5 months for design development, as we carefully study the site's topography and optimize the design for slope conditions. Permitting can take additional time due to the complexity of hillside construction requirements. Construction timeframes range from 8-20 months depending on project scope and site challenges. We work closely with you to establish realistic timelines that account for the unique aspects of building on sloped terrain.

How much does a hillside home architect cost?

Our hillside home architect fees typically range from 8-15% of construction cost for residential projects, reflecting the specialized expertise required for slope construction. We offer both percentage-based and fixed-fee structures depending on project scope and complexity. The investment in professional architectural services for hillside projects pays for itself through thoughtful design that maximizes views, manages site challenges, and ensures proper construction documentation. We provide transparent fee proposals that outline exactly what services are included for your hillside project.

Why hire an architect for your hillside home?

Hillside sites offer incredible opportunities for dramatic architecture, but require specialized knowledge to navigate successfully. Our team brings expertise in slope-specific design, from foundation systems to view optimization, ensuring your hillside home takes full advantage of its unique setting. We handle complex permitting requirements, coordinate with contractors experienced in hillside construction, and create spaces that elevate daily living while working harmoniously with the natural topography. The result is a thoughtfully designed hillside home that feels perfectly situated in its landscape.
