We offer clearly defined service packages ranging from consulting to full-service design. Most projects are quoted with a flat design fee, plus a furnishings investment and a standard procurement fee. We’ll walk through all of this transparently during your proposal review.

For full-service furnishing, we require a minimum furniture investment of $35,000, with design fees beginning at $5,000.

From deposit to final install, a typical full-room design takes about 12–25 weeks. This depends a lot on what options are chosen, custom furnishing, etc.  We’ll provide a realistic timeline for your specific scope during the proposal phase.

We follow a structured, multi-phase process that includes Discovery, Design, Procurement, and Installation. Every step is communicated clearly with check-ins, visuals, and progress updates.

You’ll receive a Client Guide to help you understand what to expect at the start of the project.

We use email for formal communication. For ongoing projects, we set regular meeting rhythms and check-ins to keep everything moving smoothly.

Think about how you use your space, what’s working, what’s not, and any images or inspiration that reflect your style. If you have floor plans or a Pinterest board, feel free to share!

We work primarily in the Seattle metro area, including Ballard, Queen Anne, Magnolia, and surrounding neighborhoods. We also take on remote projects in select locations such as Montana and even abroad, like Germany. If we’re a great fit, we’ll find a way to work together.

We typically book projects 1–3 months in advance. If you have a target start date in mind, reach out early to reserve your place in our schedule.

We combine creative vision with precise execution. Our European sensibility means we value timelessness over trends, and our corporate leadership background ensures nothing falls through the cracks. We're known for being as organized as we are inspired.

Yes, we handle all furniture sourcing, ordering, and installation. If you have pieces you’d like to keep, we’re happy to incorporate them where possible and build around what matters most to you.

Absolutely. Many of our design decisions support function as much as beauty. We create systems that work for how you think, live, and feel in your space.

We specialize in working with busy professionals, executives and families in Seattle, many of whom work in the tech industry. Our clients often have beautiful homes they've lived in for several years but haven't quite managed to tackle. Some struggle with challenging layouts or making design decisions, while others simply don't have the time or bandwidth to take on another project. They value quality, thoughtful design and a trusted professional who can bring everything together without making their home another item on their to-do list.

Neuroaesthetic interior design explores how our surroundings influence how we feel and experience a space. Drawing on principles of neuroscience and design, we consider light, color, texture, materials and spatial layout to create environments that support comfort and well-being. Leonhard & Fritz Interiors is certified through Science in Design, bringing research-informed principles into our approach to creating beautiful, restorative homes.

Yes. Biophilic design is an integral part of our approach. We incorporate natural light, organic materials, greenery, nature-inspired colors and textures, and connections to the outdoors. Together with our training through Science in Design, these principles inform how we create warm, timeless homes that offer a welcome counterpoint to busy, technology-driven lives.

Absolutely. Many of our clients have lived in their homes for several years but haven't found the time or clarity to pull everything together. Whether you're struggling with an awkward layout, furniture that doesn't quite work or rooms that still feel unfinished, we develop a cohesive design and manage the details from concept through installation. The result is a home that finally feels complete and reflects the way you live today.

We combine European design sensibility with a research-informed, human-centered approach to creating timeless, personal homes. Our founder, Sandra Randolph, is trained and certified through Science in Design, bringing an understanding of neuroaesthetics into our work. Equally important is our highly organized, full-service process, designed to make creating a beautiful home easier for busy professionals and families.

Yes. Many clients come to us because a room simply isn't working, whether it's an awkward furniture arrangement, challenging traffic flow or a space that doesn't serve their family's needs. We evaluate how you use the room and develop thoughtful layouts that balance function, comfort and aesthetics.

Our work combines timeless design with European character and modern refinement. Rather than following a particular style or trend, we create layered, personal interiors that respect the home's architecture and reflect the people living there. Natural materials, thoughtful lighting, texture, art and craftsmanship are central to our approach.

Yes. We favor thoughtful, lasting design over short-lived trends and incorporate biophilic principles that strengthen the connection between home and nature. Depending on the project, this may include natural materials, daylight, greenery, durable furnishings and pieces designed to be enjoyed for years.

We believe a home should be more than beautiful. It should support the way you live, feel and connect with others. Our approach combines timeless European-inspired design with principles of neuroaesthetics and biophilic design, informed by our Science in Design certification. We emphasize natural materials, thoughtful lighting, texture, craftsmanship and personal character to create warm, restorative spaces. Paired with our structured, highly personalized design process, we create homes that offer a welcome counterpoint to busy, digitally driven lives.

Absolutely. We specialize in working with busy Seattle professionals, executives and families, many in the tech industry, who want their homes to offer a counterbalance to their demanding, digitally connected lives. Our clients value beautiful, thoughtfully designed spaces that encourage more analog living, meaningful family connections and moments to slow down and recharge. Often, they simply lack the time or bandwidth to bring that vision to life. Our full-service approach combines timeless design with principles of neuroaesthetics and biophilic design, creating warm, personal homes that help you disconnect from the outside world and reconnect with what matters most.
