Do I need a licensed architect for residential interior design?

In Washington State, a licensed architect isn't always required for interior work, but is highly recommended when structural changes are involved. We bring expertise in building codes, structural systems, and permitting that ensures your interior renovation is both beautiful and safe. Our architectural training allows us to see possibilities others might miss while navigating complex regulations.

What does residential interior design construction cost?

Interior renovation costs vary widely based on scope, materials, and level of customization. Factors include whether you're moving walls, updating systems, or focusing on finishes and fixtures. Kitchen and bathroom renovations typically require higher investment due to plumbing and electrical work. We help establish realistic budgets early in the design process.

How long does residential interior design take?

Interior design development typically takes 2-4 months, depending on project complexity and decision-making pace. Construction timelines vary from 2-6 months for most interior renovations, with kitchens and bathrooms often requiring longer due to specialized trades. We provide detailed timelines during the design phase to help you plan accordingly.

How much does a residential interior design architect cost?

Our architectural fees for interior design projects typically range from 10-15% of construction cost, varying based on project complexity and scope of services. We also offer hourly consulting for smaller projects or design-only services. Our detailed drawings and specifications often save money during construction by preventing costly changes and miscommunication.
