The real estate market in New York City is seeing peak demand, with many young families flocking to Manhattan in hopes of finding their slice of forever. However, because many potential buyers are first-timers, the questions surrounding the purchase come in abundance - especially with so many routes available to renovate in NYC. 

One common consideration from clients at the top of the renovation funnel is - should I hire an architect or an interior designer for my project? While that could be articulated many ways, the answer really comes down to what type of work is required as part of your potential renovation. 

In this article, we’ll explain the similarities and differences between these two desirable renovation routes, along with specific jobs that each role may be most appropriate for - all from the unique perspective of a full-service design-build general contractor that enlists both architects and designers.

[#1]Understanding The Role Of An Architect[#1]

Is an architect needed for your upcoming apartment renovation in New York City? Let’s dig into this articulated role and weigh how the specific expertise might factor into your project.

What Types of Renovations Are Best For Architects?

Architects are required for your NYC renovation when the project involves structural changes, the movement walls, or layout changes that require building code compliance. There are other instances where architects are required - for example, some buildings require an architect for renovations that do not entail layout changes. These structural design experts draft detailed plans for your renovation, while also guaranteeing the project meets local building codes. 

How Do Architects Work With Other Contractors?

In renovations driven by traditional general contractors, architects typically work with general contractors to bring their completed plans to life. In this case, traditional general contractors focus on managing the construction process, coordinating trades, and ensuring that the renovation aligns with the architect’s design. This setup can lead to effective project execution but requires clear communication between the architect and the contractor to prevent missteps.

[#2]When To Choose An Interior Designer[#2]

Is an interior designer essential for your NYC overhaul? Let’s dive into this elemental role in NYC renovations and how their vision and expertise can transform your space.

What Types of Renovations Are Best For Architects?

Interior designers specialize in optimizing space, selecting materials, and crafting the overall aesthetic of your home. These creative gurus create functional and visually appealing environments, which is essential when renovating in NYC apartments, where maximizing space is crucial. 

How Do Interior Designers Work With Other Contractors?

When working with a general contractor, interior designers are often brought in to guide design details and material selections, while the contractor focuses on construction. However, their role expands significantly within full NYC apartment renovations, particularly dated pre-war renovations that require thoughtful design that can honor a building’s history while modernizing the aesthetics, layout, and functionality.

In these projects, interior designers deliver a refined, cohesive vision—whether for a complete apartment transformation, a high-end apartment refresh, or a strategic layout optimization that makes the most of limited space. Their expertise ensures efficient spatial design planning, which is vital when considering NYC’s costly square footage. Beyond structural considerations, they curate furniture, lighting, and custom millwork to enhance both form and function. 

Interior designers are not to be confused with interior decorators, who focus more on aesthetics, such as furniture, color schemes, and décor, rather than the structural and spatial planning aspects of a renovation. Decorators refine the look and feel of a space, while designers shape the functionality and flow, ensuring furnishings complement the broader architectural vision.

[#3]Where Architecture and Interior Design Intersect in NYC Renovations[#3]

When planning a renovation, understanding the roles of architects and interior designers is key—but knowing where they intersect is equally important. As a full-service design-build firm, we integrate both disciplines to create spaces that are structurally sound, highly functional, and beautifully designed. While architects focus on layout, code compliance, and structural integrity, interior designers refine the space with materials, finishes, and details that enhance both aesthetics and livability.

Different Approaches to Space Planning

Architects take a big-picture approach, ensuring the structure supports your vision—whether that means reconfiguring walls, adjusting ceiling heights, or integrating mechanical systems. Their expertise is critical for major layout changes, especially in co-ops and pre-war buildings where approvals and structural modifications come into play.

Interior designers, on the other hand, focus on how the space is experienced. From maximizing flow in a compact apartment to curating materials that bring warmth and cohesion, their work ensures every square foot is thoughtfully considered. Whether that requires selecting millwork, optimizing furniture layouts, or fine-tuning lighting design, they bring the polish that turns a renovation into a fully optimized home.

When You Need Both

Many projects benefit from the combined expertise of architects and interior designers. For example, in a Sutton Place co-op we renovated at 425 East 58th, we removed walls to create a more open, modern layout—an architectural challenge that required careful planning. But the transformation was not complete until the project’s assigned interior designer curated the finishes, custom millwork, and lighting scheme that gave the space elevated character.

In our Upper West Side apartment renovation at 91 Central Park West, zoning the space effectively was just as important as selecting the right finishes. Our in-house architect was required to reengineer the flow of the kitchen, while our interior designers ensure that those divisions feel cohesive, comfortable, and catered towards the client’s goal of having a more industrial-friendly kitchen.

The key is having both skill sets seamlessly working together from the start. That’s where Gallery comes into play. With our integrated design-build approach, you are not managing multiple teams—we handle everything, ensuring your renovation is efficient, strategic, and tailored to your vision.

[#4]Factors To Consider When Making Your Decision[#4]

Choosing between an architect and an interior designer for your NYC renovation depends on several key factors. Budget, project scope, and the extent of structural changes all play a role in determining which professional—or combination of professionals—is best suited to your needs. Priorities to consider, include;  

Project Scope and Structural Changes

If your renovation involves altering the layout—removing or adding walls, relocating plumbing or electrical systems, or modifying structural elements—an architect is essential. They ensure that changes comply with NYC building codes, co-op or condo board regulations, and structural requirements.

On the other hand, if your renovation focuses on finishes, space planning, or enhancing the aesthetic and functional flow of a home, an interior designer is key. They guide material selections, curate furnishings, and ensure that every detail, from millwork to lighting, contributes to a cohesive, well-executed design.

Budget Considerations

Architectural services tend to be more expensive due to the technical expertise and permitting processes involved. If your project requires substantial layout changes, budgeting for an architect is a necessity. Interior design services, while variable in cost, are often more flexible depending on the level of involvement—from simple design consultations to full-service selections and procurement.

[#5]How A Design-Build Firm Bridges The Gap[#5]

For NYC homeowners torn between hiring an architect vs interior designer, a design-build firm offers a seamless solution—integrating both under one roof for a more efficient, cohesive renovation.

A Unified Team for Better Results

In a design-build firm, architects handle structural planning and approvals, while interior designers refine layouts and materials. Working together from the start, they eliminate disconnects between design and construction, ensuring a smooth, aligned process.

Cost and Time Savings

With a design-build approach, potential issues are addressed early, minimizing costly revisions. Clients also get more accurate estimates upfront, and with fewer handoffs, projects move faster and more efficiently.

A Full-Service Approach

Beyond architects and designers, structural engineers, millworkers, and project managers are all part of the process—reducing client coordination headaches. For those seeking a streamlined, expert-managed renovation, a design-build firm is the smartest choice.

‍

[#6]Decision Framework: Who to Hire and When[#6]

• If your renovation involves structural work (wall removals, layout reconfigurations, MEP system updates), an architect is required.

• If your focus is on aesthetics, space planning, and finishes, an interior designer is the right fit.

• For a full-scale renovation where both structure and design are priorities, work with a design-build firm that integrates both services for a seamless, efficient process from concept to completion.

By understanding the scope of your project and what each profession brings to the table, you can make an informed decision that sets your renovation up for success. And if you are looking for a firm that brings both architecture and interior design together under one roof, Gallery is here to help - even if you’re just beginning the process and need some advice.

Full Renovation Of Pre-War Co-Op In Manhattan | 1035 5th Avenue

Our renovation at 1035 5th Ave found us overlooking Central Park, overhauling a beautiful Italian Renaissance Palazzo co-op located on Fifth and 85th, just down the street from The Met. When our client purchased this 4,000 square foot pre-war property, the space hadn’t been updated in more than 50 years. The vision for this renovation called for a total design overhaul of the extensive space, while incorporating many of the prior architectural elements and elegant marble accents, plus creating an additional bathroom and powder room. While the results speak for themselves, the client’s glowing praise for our full-service approach went a long way. View the full apartment renovation via our Before + After portfolio.
