Remodeling an existing home is a different kind of project than building new — more constrained in some ways, more demanding in others. You’re working with what’s there: existing structure, existing systems, existing layout decisions made by someone else decades ago. The design challenge is to work with those constraints intelligently, adding what the home needs without compromising what already makes it work.
In Western North Carolina, remodel projects are a significant part of the residential architecture landscape. The region’s existing housing stock ranges from mid-century mountain cabins to 1970s–1980s contemporaries to more recent homes that need updating. Many of these homes have good bones and spectacular sites but layouts, systems, or finishes that no longer serve their owners well.
This page covers what a major home addition or remodel project involves when an architect is engaged: how the process works, what costs to expect, what the most common scope decisions look like, and how to know when the project scope warrants architectural services versus a contractor-only approach.
Not every remodel requires an architect. Replacing a kitchen’s cabinets and appliances, updating bathroom finishes, or repainting don’t require design professional involvement. When a remodel crosses into structural changes, additions of square footage, changes to the home’s exterior, or systems work that requires permits, the case for architectural involvement strengthens considerably.
In North Carolina, an architect’s seal is required on construction documents for certain project types and scopes. Beyond the legal requirement, there are practical ones. A home addition that changes the roofline needs to be designed to integrate with the existing structure — which requires understanding the existing structure. A floor plan modification that removes a wall needs to account for what that wall is carrying. A basement conversion needs to address moisture, egress, and mechanical systems.
The most common scenarios where architectural involvement in a remodel project delivers clear value:
Major additions. Adding square footage — a new wing, a second story, an expanded kitchen and living area — involves structural engineering, exterior design integration, and systems coordination that requires professional design services.
Whole-home renovations. A gut renovation that addresses structure, mechanical systems, envelope performance, and interior layout throughout the home is effectively a design project of comparable complexity to new construction, minus the site work.
Steep slope remodels. Remodel projects on steep WNC sites, where the existing structure may be on a complex foundation and any addition needs to work with the topography, add site-specific complexity that an architect with local experience is best equipped to handle.
Historic or distinctive homes. Remodeling a home with architectural significance, or a home in a neighborhood with design review requirements, benefits from a design professional who can respect the existing character while making meaningful improvements.
The Timberline Revival project in Bent Creek, West Asheville, shows what a comprehensive residential renovation looks like: a home that had good structural bones and a strong site but needed a complete design reconception to reach its potential.
Every remodel project at Form & Function begins with an existing conditions assessment. This is the equivalent of a site analysis for new construction — it establishes the baseline of what’s there before any design begins.
An existing conditions assessment typically includes:
Physical documentation. Measured drawings of the existing floor plans, elevations, and sections. Confirmation that the as-built conditions match any available original drawings, which they often don’t.
Structural assessment. Identification of load-bearing walls, beam and column locations, foundation type, and any visible structural issues. This doesn’t replace a structural engineer’s analysis, but it identifies where engineering input will be needed.
Systems review. Age and condition of HVAC, electrical, and plumbing systems. Identification of any code compliance issues with existing systems that will need to be addressed as part of the renovation.
Envelope condition. Insulation levels, air sealing quality, window condition, and any moisture intrusion evidence in walls, attic, or crawl space. These conditions have direct implications for both energy performance and structural integrity.
Code compliance review. Identification of any existing conditions that are out of compliance with current building code that would need to be addressed when a permit is pulled.
The time spent on existing conditions documentation is among the most valuable in a remodel project. It reduces the likelihood of construction surprises — finding knob-and-tube wiring when a wall is opened, discovering that a beam thought to be structural is not, uncovering moisture damage in a wall assembly — that are expensive to address mid-construction.
Adding a second story to a single-story home is one of the most common addition types in WNC, and one of the most structurally demanding. The existing first-floor walls and foundation must be evaluated for their capacity to carry the additional load of a second floor — in many homes built in the 1970s–1990s, they were not designed for this.
A second-story addition requires a structural engineer’s assessment of the existing foundation and first-floor framing before design can be completed. If the existing structure is inadequate, the addition cost increases to include foundation reinforcement, wall upgrades, or point load transfer systems. This evaluation happens during design development, and the structural engineer’s findings shape the final design and cost.
The design challenge of a second-story addition is integration: making the addition look like it belongs to the original home rather than being plopped on top of it. This involves roofline coordination, window alignment, exterior material continuity, and a clear logic for how the two stories relate in plan and section.
Removing walls to open up a floor plan is among the most requested remodel scopes in WNC — and among the most commonly underestimated in terms of what’s involved. Before any wall comes down, the structural implications need to be understood.
A wall that appears to be non-structural may be carrying point loads from above — from a beam, from a post, from a roof valley. A wall in a crawl-space home may be sitting on a girder that runs across the foundation; removing the wall doesn’t remove the load path. An exterior wall removal to create a connection to a deck or patio involves weatherproofing details that are easy to get wrong.
Structural engineering is required for any floor plan modification that removes or modifies load-bearing walls. The structural engineer designs the replacement structure — typically a beam sized for the span and load, with appropriate posts or pilasters at the ends — and the architecture integrates that structure into the design.
The payoff is significant. Opening a kitchen-dining-living sequence in an older WNC home, redirecting the view to the landscape, and connecting the interior to an outdoor living space can transform how a home feels and functions without adding a square foot.
Remodel costs are harder to generalize than new construction costs because they depend so heavily on what’s discovered during construction. That said, some benchmarks are useful for planning:
Kitchen renovation, mid-to-high range: $75,000–$150,000, depending on scope, appliance selection, and custom millwork.
Bathroom renovation, primary suite: $35,000–$75,000 for a full gut and reconstruction with quality finishes.
Room addition, finished space: $275–$400+ per square foot, comparable to new construction per-square-foot costs with the addition of connection costs (integrating into the existing structure, roofline, and systems).
Whole-home renovation: Highly variable. A gut renovation of a 2,500-square-foot home that addresses structure, systems, envelope, and finishes throughout may cost $400,000–$700,000 or more depending on the extent of systems replacement and finish quality.
These numbers are starting points, not fixed quotes. The actual cost of a remodel project is established through contractor bidding after construction documents are complete — and the quality of those documents directly affects how accurate and complete the bids are.
For more context on how remodel projects differ from new construction in terms of cost and process, our home renovation guide goes deeper on planning, budgeting, and managing construction.
Our residential portfolio includes remodel and addition projects of varying scope across Asheville and the surrounding WNC region.
The Timberline Revival in Bent Creek, West Asheville, represents a comprehensive transformation of an existing mountain home — one of the more ambitious renovation projects in the portfolio.
The Skyline Revival in Asheville is another example of a significant renovation that reimagines an existing home’s relationship to its site and landscape.
The Mountain Home project in Swannanoa shows how targeted improvements — strategic additions and material updates — can substantially change what an existing home offers without a complete gut renovation.

For additions that require a building permit — which includes any addition of conditioned square footage, any structural modification, and most exterior changes — construction documents prepared or reviewed by a licensed architect are required in North Carolina above certain square footage thresholds. Even for projects that fall below that threshold, architectural involvement in design and permitting typically produces better outcomes: more accurate contractor bids, more complete permit submissions, and a design that integrates the addition with the existing home rather than just attaching to it.
The short answer is: have a structural engineer assess it before any work begins. Common indicators that a wall may be load-bearing include walls that run perpendicular to floor joists, walls that stack from floor to floor in multi-story homes, and walls that sit over a beam or foundation wall in the crawl space or basement. But these are indicators, not guarantees — only a structural assessment of the specific conditions can confirm what a wall is carrying. We coordinate structural engineering as part of our remodel design process.
Building permits are required for any structural work, additions of square footage, changes to the electrical or mechanical systems, and most exterior modifications in Buncombe County and the City of Asheville. A permit application requires construction documents that describe the scope of work, the existing and proposed conditions, and all relevant code compliance. We prepare permit-ready documents and manage the submission and review process for our clients.
Design for a whole-home renovation typically takes 4–8 months, depending on complexity and how quickly decisions can be made. Construction takes 6–18 months, depending on scope. The total elapsed time from starting design to moving back in is typically 12–24 months for a comprehensive renovation. Phased renovations — where work is divided into stages that allow occupation of part of the home during construction — can reduce disruption but extend the overall timeline.
The answer depends on several factors: the quality of the existing structure, the lot’s development potential, your program requirements, and the economics of the two options in your specific situation. Building new on a lot with a teardown-quality structure often makes financial sense. Renovating a home with a good structural skeleton, a desirable location, or significant architectural character often makes more sense than demolishing and rebuilding. We can help you evaluate both paths as part of a feasibility conversation. Contact us through our contact page to discuss your situation.
In common usage, the terms are often interchangeable. In a strict sense, a renovation restores something to its original or improved condition, while a remodel changes the form, structure, or purpose of a space. In practice, the distinction matters less than the scope: whether the project involves structural changes, additions of square footage, systems replacement, or cosmetic finishes, and what combination of those applies to your specific project.
Yes, though we approach kitchen and bathroom design as part of a whole-home design conversation rather than as isolated scopes. A kitchen renovation that improves the layout but ignores its relationship to adjacent living and dining spaces misses an opportunity. A bathroom renovation that doesn’t consider the master suite’s relationship to storage, dressing, and the bedroom misses an opportunity. When clients come to us for a kitchen or bathroom project, we typically begin with a conversation about the whole home to make sure the targeted work serves the broader design logic. Browse our residential portfolio for examples of interior spaces that reflect this approach.
The best place to start is a site visit. We come to your home, look at what you have, listen to what you want, and give you an honest assessment of what the project involves and what it’s likely to cost. That conversation shapes everything that follows.
