A direct answer to the question every prospective client asks first.
The most honest answer to the cost question is that it depends — on the project’s size, complexity, site conditions, and scope of services. That is not an evasion; it is the reason most architecture firms don’t publish fixed-rate pricing. A 1,200-square-foot ADU on a flat lot with straightforward permitting and a defined program requires genuinely different design work than a 4,000-square-foot custom home on a steep ridge lot with passive solar integration, complex drainage, and a multi-agency permitting process.
What is possible to say with reasonable specificity is how fees are typically structured and what drives cost within each structure. Understanding that framework helps prospective clients evaluate quotes realistically and ask better questions when comparing proposals from different firms.

For full-service residential architecture — site analysis through construction administration — fees in Western NC typically fall in the range of 8 to 15 percent of total construction cost. Where a specific project lands within that range depends primarily on complexity.
Projects at the lower end of the fee range tend to be simpler: relatively straightforward floor plans, standard structural systems, flat or gently sloping sites, program elements the architect has designed many times before, and jurisdictions with predictable permitting processes. Projects at the higher end tend to involve more design work per square foot: complex or novel structural solutions, steep-slope or challenging site conditions, passive solar integration, historic district review, or unusually detailed interiors that require extensive coordination with interior design work.
The percentage-of-construction-cost fee structure means that as the project gets more expensive — because of larger square footage, higher finish levels, or more complex construction — the fee grows proportionally. This alignment works well for most full-service residential engagements because the design complexity typically does scale with construction cost: a more expensive home usually has more decisions to make, more coordination to manage, and more construction administration to provide.
For context: a custom home with a $600,000 construction budget at a 10 percent fee produces a $60,000 architecture fee for full services from site analysis through construction administration. A simpler project at the same budget with a more straightforward program and site might come in at 8 percent; a more complex project at the same budget might come in at 12 percent.
The percentage-of-construction-cost fee model is the most common structure for full-service residential architecture engagements, but it is not the only one. Understanding when each fee structure makes sense helps clients evaluate what they are being quoted.
Percentage of construction cost works well when the full scope of services is being provided from schematic design through construction administration, and when the project complexity is commensurate with the construction budget. It aligns the architect’s effort with the project’s scale and is transparent to clients because the fee tracks a number that becomes more precisely known as the project develops.
Hourly rates are more appropriate for limited-scope engagements — feasibility studies, design consultation on projects where a contractor is leading the build, permit document preparation for defined scopes, or construction administration on projects where another firm prepared the design. Hourly rates in WNC for licensed residential architects typically reflect experience level and firm overhead. For smaller remodel and renovation projects, hourly arrangements give clients flexibility to engage the architect’s services for specific questions without committing to a full-service fee.
Fixed fees are negotiated when the scope is well-defined enough to price accurately — most common in the construction documents phase for projects where schematic design is already complete, or for specific scopes like as-built documentation, existing conditions assessment, or interior design services with a defined deliverable. Fixed fees give clients certainty about the cost of a specific phase, which some clients prefer even when the overall engagement continues on a percentage or hourly basis.
Building a custom home in WNC in 2026 requires a realistic understanding of current construction costs and how they vary by project type, finish level, and site conditions.
Construction costs for custom homes in the Asheville market have ranged from approximately $200 to $350 per square foot in recent years for finished living area, depending on finish level and site conditions. These figures reflect direct construction costs — contractor and subcontractor labor and materials — and do not include land cost, architecture fees, civil and structural engineering, site development (clearing, access road, utilities), or permit fees. A complete project budget for a custom home typically runs 15 to 25 percent above the construction cost alone when all soft costs are included.
Finish level is the largest variable within the construction cost range. A home built with standard production finishes — contractor-grade cabinetry, standard tile and fixture packages, painted drywall throughout — comes in at the lower end of the range. A home with custom millwork, natural stone throughout, high-performance windows, specialty exterior materials, and a detailed landscape plan comes in at the upper end. Most custom homes in the WNC market land somewhere between the two.
Site conditions are the second major cost variable. A gently sloping lot with good road access and existing utility connections to the property line requires minimal site development cost beyond standard grading and foundation work. A steep mountain lot requiring cut-and-fill earthwork, engineered retaining walls, a long driveway, and extended utility runs from the road adds meaningfully to the preconstruction budget — and those costs are paid before framing begins.
The most important budget planning tool is an honest early conversation about all three components: construction cost, architecture and engineering fees, and site development costs. Form & Function’s site visit and analysis phase includes preliminary cost guidance on all three, which gives clients the information they need to make realistic decisions about scope and program before significant design investment is made.
Each fee structure has genuine advantages in specific contexts, and the best structure for a given engagement depends on what the client needs and what the project requires.
The percentage-of-construction-cost model provides the best alignment of effort and fee for full-service engagements on custom homes. The main limitation is that the fee is not fully determined until the construction cost is known — which happens in stages as the design is developed and ultimately when contractor bids are received. Clients who need budget certainty earlier in the process may find this uncomfortable, though preliminary cost modeling in the schematic design phase gives a reliable basis for fee estimation.
Hourly billing is the most flexible structure for clients who want to engage the architect’s expertise for specific questions without committing to a defined scope. The limitation is that the total cost is not known in advance and depends on how much time the work actually takes. For clients who need a fixed budget for architectural services, hourly billing requires a detailed scope and an estimated range that both parties monitor.
Fixed-fee billing provides clients with certainty about the cost of a specific scope of work. For well-defined scopes — construction documents for a schematic design that is already approved, permit document preparation for a defined addition, as-built documentation for an existing home — fixed fees work well. For less defined scopes where the amount of design iteration required is unknown, fixed fees can create pressure to limit the design process in ways that don’t serve the client’s interests.

The lowest architecture fee does not produce the best project outcome, and in many cases it produces the most expensive one — measured by total project cost, not just design fee.
The specific ways cheaper design services add cost elsewhere in the project are predictable. Incomplete or poorly coordinated construction documents produce contractor bids that are less accurate and less comparable — which means either the low bid reflects a misunderstanding of the scope (producing change orders during construction) or the client is not getting the most competitive pricing because bidders are padding for uncertainty. Construction administration that is minimized or omitted means less oversight of whether the contractor is building what the drawings specify — which produces conditions that are difficult and expensive to correct after the fact. Design advice that doesn’t reflect local site knowledge, regional construction costs, or WNC permitting requirements produces projects that go over budget, take longer than planned, or don’t perform as the client expected.
The value of experienced residential architectural services is not in the drawings themselves — it is in the accumulated knowledge that informs every decision along the way: where to put the building on the site, which structural approach works for the soil conditions, which finishes hold up in WNC’s climate, how to write a scope of work that produces competitive contractor bids, which contractor questions during construction require design changes and which can be resolved with a clarification. That knowledge has a cost, and the cost is usually less than the problems that result from not having it.
For clients comparing architecture proposals, understanding what a quoted fee includes — and what it doesn’t — is the most important step before making a decision.
A full-service residential architecture fee from Form & Function covers: site visit and analysis, schematic design with multiple design iterations and client review sessions, construction documents prepared in Revit, coordination with structural and civil engineers, permit application assistance, bidding process management and contractor selection support, regular construction site visits through project completion, RFI responses and shop drawing review, and project close-out documentation.
What the architecture fee typically does not cover: structural engineering fees (billed separately by the structural engineer), civil engineering fees (site grading, drainage, retaining wall design), geotechnical investigation (soil boring and report), landscape design, interior design services beyond finish selection within the architectural scope, and survey costs if a current survey of the property is required.
Understanding these inclusions and exclusions makes proposal comparison meaningful. An architecture fee that appears lower may not include coordination services that are standard in another firm’s proposal — or it may include fewer construction administration visits, which affects the level of oversight the client receives during construction.
Construction costs in the Asheville market have risen significantly over the past several years, reflecting both national material cost increases and strong local demand for construction labor. The figures below reflect general ranges observed in the WNC market in recent years; they will vary by contractor, finish level, site conditions, and the specific year the work is bid.
Standard residential construction with builder-grade finishes in WNC has ranged from approximately $180 to $230 per square foot for finished living area. This level typically includes standard production cabinetry, tile and fixture packages from standard product lines, drywall throughout, and conventional construction systems without specialty materials or techniques.
Mid-range custom residential construction — custom cabinetry, upgraded fixtures and finishes, natural material accents, good-quality windows — has ranged from approximately $230 to $300 per square foot. This is where most Form & Function residential projects land.
High-finish custom residential construction — fully custom millwork throughout, natural stone or specialty tile, high-performance triple-pane windows, specialty exterior materials, detailed landscape integration — has ranged from $300 to $400 per square foot and above for fully detailed projects at the upper end of the market.
These figures are for finished living area and do not include garages, unfinished basements, or exterior site work beyond standard foundation grading. Site development costs — access roads, utility runs, retaining walls, stormwater management — are additional and highly site-specific. Contact the studio to discuss your project’s scope and what a realistic total budget looks like for your site and program.
Bringing an architect in before you commit to a lot — or at minimum at the time of purchase — is the most cost-effective approach for custom home buyers. A site visit with an architect before purchase can identify conditions that will significantly affect construction cost (steep grade requiring extensive earthwork, poor soil conditions requiring special foundations, utility connection challenges) or that limit the building envelope (setbacks, ridge protection ordinances, flood zone proximity). Finding out after purchase that the lot cannot support the home you planned is significantly more expensive than a pre-purchase consultation.
The fee structure and scope of services can be discussed and adjusted — for instance, a client might choose to handle some phases on a limited-service basis rather than full-service, which would adjust the fee accordingly. The fee rate itself reflects the cost of the professional services being provided and does not have significant room for downward negotiation without a corresponding reduction in services. The most productive fee conversation is one focused on clearly defining what services are included so that the client understands exactly what they are getting for the quoted fee.
A feasibility study is a preliminary design service that evaluates whether a proposed project is achievable on a specific site within a defined budget and program. For residential projects, it typically involves a site visit, preliminary zoning and code review, rough square footage and cost modeling, and a written summary of what the site can support and at what approximate cost. Feasibility studies help clients make informed go/no-go decisions before committing to full design services. Form & Function offers residential feasibility assessments as an independent service; contact the studio for current pricing based on your site and project type.
If the fee is structured as a percentage of construction cost and the construction budget increases — due to scope expansion, market cost escalation, or change orders — the fee would technically increase proportionally. In practice, fee adjustments during construction for cost-of-living increases or modest scope changes are handled case by case based on what drove the cost increase. Significant scope changes that require substantial additional design work are addressed through a supplemental fee agreement. Form & Function discusses this framework transparently at the start of each engagement so clients understand how the fee structure responds to project changes.
Comparing proposals from multiple architects is reasonable for any significant residential project. The most useful comparison is not price — it is fit: which firm’s process, communication style, portfolio, and principal expertise best matches what your project needs? Price comparisons between architecture proposals are meaningful only when the scope of services is identical, which requires careful proposal review. A significantly lower proposal that excludes construction administration, omits coordination services, or assumes a shorter design process is not a comparable product to a higher proposal that includes them.
