Architecture & Interior Design: Frequently Asked Questions

Hiring an Architect

An architect plans and designs buildings and spaces that respond to people's needs while addressing functionality, aesthetics, safety, and technical requirements. Architects may guide projects from early planning and concept development through design documentation, permitting, and construction.
Beyond designing how a building looks, architects consider how spaces are experienced and used, how they relate to their surroundings, and how they can adapt over time. Architects also coordinate with engineers, consultants, contractors, and other specialists to translate design ideas into built environments.
The architect's role is both creative and technical, balancing a client's vision with the practical requirements of bringing a project to life.
Architectural fees vary depending on the project's size, complexity, location, and scope of services. Architects typically charge a fixed fee, an hourly rate, or a percentage of construction costs.
Fees also depend on the level of involvement required. Some projects need comprehensive architectural services, from initial planning through construction, while others may benefit from more focused services such as feasibility studies, programming, or concept design.
When evaluating architectural fees, it's important to understand which services are included, what consultants may be required, and how changes to the project will be handled. A clearly defined scope of work helps establish realistic expectations and allows clients to compare proposals more effectively.
deally, an architect should be involved as early as possible, often before purchasing or leasing a property, establishing a final budget, or making significant decisions about a project.
Early architectural involvement can help identify opportunities, evaluate site or building constraints, establish space requirements, and determine whether a proposed project is feasible. Architects can also help clients understand potential construction costs, regulatory requirements, and project timelines before major financial commitments are made.
Whether you're planning a new building, commercial renovation, workplace transformation, or residential project, involving an architect during the initial planning stages can help establish a stronger foundation for design and decision-making.

Architects and interior designers both shape the built environment, but their areas of expertise and professional responsibilities differ.
Architects are trained to design buildings and coordinate their spatial, structural, technical, and regulatory requirements. Interior designers focus on the functionality and experience of interior environments, including space planning, materials, finishes, lighting, furnishings, and the relationship between people and their surroundings.
The disciplines frequently overlap, particularly in interior architecture projects involving significant changes to existing buildings.
An integrated approach to architecture and interior design can help create cohesive environments where architectural character, spatial organization, materials, and furnishings work together.
Choosing an architecture firm involves more than finding a design style you like. Look for a firm with relevant project experience, a clear design process, and an approach that aligns with your goals and priorities.
Review the firm's portfolio, understand the services it provides, and ask how it approaches collaboration, budgets, and project challenges. It's also important to consider how well the design team listens, communicates, and understands the needs of the people who will use the space.
A successful architectural project depends on a strong working relationship. The right architect should bring creative expertise while helping you make informed decisions throughout the process.

Architectural Services and the Design Process

Architectural projects typically follow a series of interconnected phases, from early planning and strategy through design and construction. While the process varies depending on the project's size, complexity, and scope, the key phases include:
- Feasibility: Evaluating site or building conditions, regulatory requirements, project constraints, and potential opportunities to determine whether a project is viable.
- Programming & Strategy: Understanding client goals, user needs, operational requirements, and future aspirations through research and collaboration to establish a clear project brief and spatial strategy.
- Concept Design: Translating the project's vision and strategic goals into initial design ideas, exploring spatial organization, architectural character, and the overall design direction.
- Schematic Design: Developing the selected concept into a more defined architectural design, including layouts, building systems, and preliminary material selections.
- Design Development: Refining the design through detailed coordination of materials, building systems, and architectural elements.
- Construction Documents: Preparing detailed drawings and specifications for permitting, pricing, and construction.
- Bidding & Negotiation: Assisting with contractor selection, pricing, and procurement.
- Construction Administration: Reviewing construction progress, responding to questions, and helping ensure the completed project reflects the design intent.
At Callaghan Horiuchi, research, collaboration, and human-centered design inform every phase, helping ensure that the final environment responds to both the project's goals and the people who use it.
The duration of an architectural project depends on its size, complexity, regulatory requirements, and the scope of services involved.
A focused feasibility study or concept design exercise may take several weeks, while the design and documentation of a commercial interior renovation may take several months. Larger new buildings and complex renovations often require substantially longer design and approval periods.
Construction adds a separate phase, with timelines influenced by permitting, contractor availability, material procurement, and site conditions.
Establishing realistic milestones early in the process helps clients coordinate business objectives, budgets, and construction schedules. An architect can help identify critical decisions and potential challenges that may affect the overall timeline.
An architectural feasibility study evaluates whether a proposed project is practical before significant resources are committed to design or construction.
A feasibility study may examine building or site conditions, zoning regulations, allowable uses, spatial requirements, accessibility, construction constraints, preliminary costs, and potential design opportunities.
For example, a business considering a new office, restaurant, or hospitality space may use a feasibility study to determine whether a particular property can accommodate its needs.
Feasibility studies combine technical evaluation with an understanding of the client's goals, helping identify opportunities, assess risks, and inform decisions about how to move forward.

Architectural programming is the process of defining what a building or space needs to accomplish before design begins.
Programming involves understanding the people who will use a space, their activities, operational requirements, relationships, and future needs. This may include stakeholder interviews, workshops, observational research, space utilization studies, and the development of detailed space requirements.
Effective programming helps ensure that design decisions are based on a clear understanding of how a space should function, rather than assumptions about what it should contain.
At Callaghan Horiuchi, programming is a fundamental part of our human-centered design approach, helping translate organizational goals and user needs into thoughtful spatial strategies.
Yes. Depending on their scope of services, architects can assist clients with contractor selection, construction bidding, and the construction process itself.
During bidding, an architect may help identify qualified contractors, respond to questions, review proposals, and evaluate whether pricing aligns with the project requirements.
During construction, architects typically review shop drawings and material submissions, visit the site to observe progress, respond to requests for information, and help resolve design-related issues.
The architect's role is generally to help administer the construction contract and evaluate whether work conforms to the design documents. The contractor remains responsible for construction means, methods, sequencing, and site safety.

Commercial Architecture and Interior Design

Commercial interior design focuses on creating functional, engaging, and purposeful environments for businesses, organizations, and public-facing institutions.
Projects may include offices, hospitality venues, restaurants, retail spaces, museums, and other commercial or institutional interiors. Unlike residential design, commercial interiors often involve complex operational requirements, accessibility standards, building regulations, brand considerations, and the needs of diverse user groups.
Successful commercial interior design balances visual identity with practical performance, considering how people move through, interact with, and experience a space.
At Callaghan Horiuchi, our commercial interior design work combines research, programming, spatial planning, materials, and furnishings to create environments that support both organizational goals and human experience.
Interior architecture focuses on the spatial and architectural qualities of a building's interior, often involving changes to layouts, partitions, circulation, ceilings, and the relationship between interior spaces and building systems.
Interior design encompasses a broader range of considerations related to the function, character, and experience of interior environments, including space planning, materials, finishes, furnishings, and lighting.
In practice, these disciplines are closely connected and frequently overlap. Professional responsibilities and licensing requirements vary by jurisdiction.
An integrated approach to interior architecture and interior design helps create environments where spatial organization, architectural details, materials, and furnishings contribute to a unified experience.
A workplace strategy consultant helps organizations understand how their physical environments can better support employees, business objectives, and evolving ways of working.
Workplace strategy often involves research into organizational culture, work patterns, employee needs, space utilization, collaboration, and future growth. The resulting recommendations may address office size, workplace typologies, space allocation, hybrid work, amenities, and opportunities for flexibility.
Unlike traditional office design, which may begin with a predefined space requirement, workplace strategy asks what kinds of environments an organization actually needs.
Callaghan Horiuchi combines workplace research, programming, and design to create adaptable environments that support focus, collaboration, well-being, and organizational identity.

Office renovation costs vary considerably depending on location, building conditions, project complexity, and the quality of finishes and building systems.
A relatively simple office refresh involving new finishes and furnishings will generally cost less than a comprehensive interior renovation requiring new partitions, mechanical and electrical systems, lighting, and significant infrastructure upgrades.
Costs are also influenced by local construction markets, building regulations, contractor availability, and material selections. In addition to construction, project budgets should account for architectural and engineering fees, permits, furniture, technology, and contingency allowances.
Early programming and feasibility studies can help establish a realistic budget, identify major cost drivers, and align project priorities with available resources.
Architecture and interior design shape how people understand, navigate, and feel within a space. In museums, cultural institutions, hospitality environments, and other public-facing destinations, thoughtful design can make the visitor experience more intuitive, comfortable, inclusive, and memorable.
Design considerations may include arrival sequences, wayfinding, accessibility, seating, gathering spaces, lighting, acoustics, and opportunities for interaction.
Understanding visitor needs through research and observation helps identify barriers and opportunities that may not be immediately apparent.
Callaghan Horiuchi's visitor experience work combines research, programming, and design to create welcoming environments that respond to different needs, encourage exploration, and support meaningful connections between people and place.
