about us

the foundation

Josh Hissong and Armando Hurtado have built a team of architects and designers who believe the places people work, live, and play can transform their experiences and improve their lives. Since launching HDG in 2010, they have grown the business alongside a team of passionate professionals into a multidisciplinary firm that specializes in architecture and collaborates with interior designers, engineers, graphic designers, and more to create cohesive, well-executed projects from concept to completion.

Until April 2026, interior design was an in-house part of HDG’s practice. That spring, Josh, Armando, and Aubrey Plaisance brought this work into Stroom Interiors, the procurement company they had built together over the preceding years. Sierra Wilson joined the team that same year, further expanding Stroom’s interior design capabilities.

Today, HDG and sister company Stroom Interiors work alongside one another to create cohesive spaces, inside and out. Our shared portfolios reflect that history and continued collaboration, spanning interiors developed within HDG and projects shaped together since. By aligning architecture, interior design, and furnishings, we offer clients a comprehensive design experience and a seamless process from concept through completion.

Our clients are at the core of everything we do. We believe the best designs come from true collaboration, blending their vision with our expertise to create residential and commercial spaces that are both functional and inspiring. Every project is an opportunity to push creative boundaries while staying committed to what matters most—delivering thoughtful, high-quality design that enhances people’s lives.

Since 2010, we’ve completed over 800 projects, spanning residential remodels, ground-up commercial projects, and, most notably, custom homes. Through it all, we’ve remained committed to refining our process and elevating the client experience.

the vision

Each team member adds a diverse style and a valued perspective to the work. As a visionary firm, they listen carefully to their clients, then lead with intention and insight to make sure the feeling of a building or space is spot on. It is an interactive, site-specific endeavor that merges art with engineering to deliver functional, extraordinary spaces that meet client needs and spark the senses.

Dedicated to fusing their designs with the community, HDG creates an evocative style that melds with the area’s history and speaks to future generations. The team analyzes, explores, and imagines while crafting uplifting designs that contribute to urban renewal, builds atmosphere, shapes people’s lives, and makes a difference. For HDG, it’s all about fashioning a more vibrant world.

the cost

Our fees are typically based on a percentage of construction cost and vary depending on project type, size, complexity, and anticipated timeframe. They are in line with industry standards, and we openly explain how our fixed fee is determined and what it includes.

Our job is to listen carefully and capture your vision. Your fixed fee will only change if you substantially change the agreed-upon scope, size, complexity, or schedule. If we overlook something you shared with us, addressing it is our responsibility.

Our work brings together a cohesive, thoughtfully appointed design and a coordinated set of construction documents for your builder. We collaborate with the necessary engineering consultants to create spaces that are functional, safe, and aesthetically cohesive.

From your first visit to HDG to your first step into your completed space, our goal is to make the design process clear, collaborative, and rewarding. A great client experience is at the heart of everything we do.
