Architectural Design and Project Planning Services Guide

Author: Brad Smith

Most homeowners think they need an architect only when they’re building a custom home from scratch. The reality is broader. Major renovations, additions, structural changes, historic restorations, mixed-use developments, and any project that has to navigate complicated permitting all benefit from real architectural involvement. The line between “we can do this with a contractor” and “we need a professional designer” is fuzzier than people assume.

Architectural firms range from solo practitioners doing single-family homes to multi-disciplinary studios handling residential renovations, commercial developments, and institutional projects under one roof. Firms like Minimalist Mountain Modern specialists HMA Architecture bring design, structural engineering, interior design, feasibility studies, project management, and help navigating local planning approvals into a single coordinated service. That kind of full-scope support exists specifically because the alternative (hiring each discipline separately) creates exactly the coordination problems that derail projects.

Whether you actually need that depth depends on what you’re building, where you’re building it, and how comfortable you are managing professional teams yourself.

Architectural Design And Project Planning Services Guide

When You Actually Need an Architect

Not every project warrants one. Knowing where the line falls saves money on smaller jobs and saves much more on bigger ones.

When You Actually Need An Architect

Projects That Don’t Need an Architect

A kitchen remodel using existing wall locations, a bathroom refresh, finishing a basement to existing structural specs, replacing windows in their current openings, repainting and refinishing, swapping out flooring. None of this needs architectural design. A good contractor can handle it, and adding an architect mostly adds cost.

Projects That Do

The list gets longer than people expect. Removing or relocating walls, adding square footage, modifying the roof line, building anything that changes the home’s footprint, working on a historic property, building on a difficult lot, or doing anything that requires variances or discretionary review. Anything custom from the ground up. Anything in a jurisdiction with strict design review boards.

The shorthand: if the project changes the building’s structure, footprint, or exterior appearance in any meaningful way, an architect adds real value. If it doesn’t, you can probably skip them.

The Permit Question

This one trips up a lot of homeowners. Many jurisdictions require stamped architectural drawings for any project above a certain scope, regardless of complexity. Adding 200 square feet to the back of your house might legally require a licensed architect’s seal even if the design is straightforward. Check with your local building department before assuming you can DIY the drawings.

What Architectural Firms Actually Offer

The services break into a few major categories. Larger firms bundle these. Smaller firms often subcontract pieces.

What Architectural Firms Actually Offer

Architectural Design

This is the core service. The architect translates what you want into drawings that contractors can actually build from. It includes schematic design (the rough concept), design development (where details get worked out), and construction documents (the detailed drawings that go to bid and to the building department).

Good architectural design isn’t just about how the building looks. It’s about how light moves through it, how spaces relate to each other, how you actually live in the rooms once they’re built. That’s the part you’re paying for, and it’s the part that’s nearly impossible to recover if you skip it.

Interior Design

Some firms offer this in-house. Others coordinate with separate interior designers. When it’s bundled, it usually means the interior decisions (finishes, fixtures, cabinetry, lighting) get integrated into the architectural drawings, which makes construction smoother.

Structural Engineering

For any project that involves load-bearing changes, removed walls, additions, or unusual lot conditions, structural engineering is a required input. Multi-disciplinary firms keep this in-house. Smaller firms partner with engineers, which works fine but adds coordination time.

Feasibility Studies

Before you commit to a project, a feasibility study answers the basic questions. Can the site support what you want to build? Will the zoning allow it? What will it roughly cost? Is the timeline realistic? Spending a few thousand dollars on a feasibility study upfront often saves tens of thousands in wasted design work on projects that never should have started.

Project Management

Some firms manage the project all the way through construction, handling the contractor coordination, schedule oversight, and decision tracking that homeowners otherwise have to do themselves. This overlaps with owner’s representation but is usually more design-focused.

Planning Approvals and Permits

In jurisdictions with discretionary review, complex zoning, or active design boards, the permitting process can take longer than the construction itself. Firms with local experience know which arguments work, which board members are sticklers about what, and how to structure submissions to avoid delays.

How the Process Actually Works

The phases are pretty consistent across firms.

PhaseWhat HappensTypical Duration
Pre-designSite analysis, feasibility, program development2 to 6 weeks
Schematic designRough drawings, concept sketches, initial planning input4 to 8 weeks
Design developmentDetailed drawings, materials, structural decisions6 to 12 weeks
Construction documentsFinal drawings for bidding and permit submission6 to 10 weeks
PermittingPlan review, corrections, approvals2 to 12 months
Bidding and contractor selectionDistributing plans, comparing bids, contract negotiation4 to 8 weeks
Construction administrationSite visits, RFIs, change orders, oversightLength of build

Add it all up and you’re looking at 6 to 18 months from “let’s hire an architect” to “construction starts.” Then the build itself. Anyone who tells you they can get through the full design and permit process in a few weeks either has very simple plans, a very forgiving jurisdiction, or is about to disappoint you.

What It Costs

Architectural fees usually fall in one of three structures.

What It Costs

Percentage of Construction Cost

The most common for residential work. Fees typically run 8 to 15 percent of total construction cost, depending on project complexity and the firm’s reputation. A $1 million custom home might carry $80K to $150K in architectural fees. That sounds high until you realize how much of the project’s eventual success depends on getting design right.

Fixed Fee

Some firms quote a flat fee based on project scope. This works well when the scope is well-defined upfront and changes are unlikely. It works poorly when the scope evolves, which it often does on custom work.

Hourly

Used for smaller projects, feasibility studies, or limited-scope engagements. Rates range from $150 to $400 per hour depending on the firm and the team member doing the work.

The fee structure matters less than what’s included. A 10 percent fee that includes structural engineering, interior design, and project management is a very different value proposition from a 10 percent fee that only covers basic drawings. Ask exactly what you’re getting.

Choosing the Right Firm

A few things to actually check before signing on.

Choosing The Right Firm

Portfolio Match

The best architect for a minimalist mountain modern home is not necessarily the best architect for a Victorian restoration. Look at the firm’s recent work. If most of it doesn’t look like what you’re trying to build, that’s a signal.

Local Experience

Architects who’ve worked in your specific jurisdiction know the planning department, the design review board, the inspectors, and the local contractors. That knowledge translates directly into faster permitting and fewer surprises.

Discipline Coverage

If your project will need structural engineering, interior design, and construction administration, find out how the firm handles each. In-house is usually smoother. Subcontracted is fine if the firm has long-standing relationships with the right specialists.

Communication Style

Some architects are designers first and communicators second. That works for some clients and not others. Spend time with the principal before signing. You’ll be talking to this person for at least a year, often more.

References From Past Clients

Talk to homeowners who actually completed projects with the firm. Ask specifically about budget, timeline, and what happened when things went sideways. The honest answers are usually more useful than the polished case studies.

Frequently Asked Questions

Do I need an architect for a renovation, or just an interior designer?

Depends on scope. If the project changes structural elements, alters the building’s footprint, or requires permits beyond basic interior work, you need an architect or at minimum a residential designer who can produce permit-ready drawings. Interior designers handle finishes, fixtures, and furnishings, not building structure.

Can I use a design-build firm instead?

Yes, if you’re comfortable with the design and construction being handled by the same company. Design-build is faster and simpler. The tradeoff is that the design firm has business reasons to push toward designs their construction arm can build profitably, which may or may not align with what’s best for you. Independent architects keep more separation between design and construction interests.

How early should I hire an architect?

Before you’ve made any concrete decisions about scope, budget, or timeline. The architect’s input on feasibility, zoning, and design constraints shapes those decisions in ways that are hard to undo later. Hiring after you’ve committed to specific plans means working backwards from constraints you’ve already accepted.

What’s the difference between an architect and an architectural designer?

Architects are licensed by the state and can stamp drawings for permit submission on any project. Architectural designers are typically unlicensed and either work under a licensed architect’s supervision or handle projects that don’t require a stamped seal. For small residential work, designers are often fine and cheaper. For anything substantial, you usually need the licensed architect.

Are architectural fees negotiable?

Sometimes. Smaller firms have more flexibility than larger ones. Fee percentages are often firmer than fee scope, meaning you might not negotiate the percentage down but can often negotiate what services are included. Worth asking either way.

Wrapping Up

Architectural services are one of those categories where the cost looks high in isolation and reasonable in context. The fee for good architectural work on a major project is small compared to the cost of building something poorly designed, missing a permitting deadline, or discovering structural problems mid-construction.

The honest assessment for most homeowners is that small projects don’t need an architect, medium projects benefit from one, and large projects can’t really succeed without one. Knowing which category your project falls into is the first useful decision. Picking the right firm for that category is the second.

If you’re on the fence, a paid feasibility consultation with a local firm is the cheapest way to find out which side of the line you’re really on.
