A successful, functional and beautiful home design project is grounded in realistic expectations regarding budget. Materials and skilled labor have risen sharply, so a number based on a friend’s renovation, or even a quote from a year ago, will no longer be a good barometer. In a July 2026 survey, home builders reported a median 6.7% increase in just material costs over the preceding year. ¹
Don’t get caught unaware. Home renovations on any scale, even a basic refresh, are objectively expensive.
A good design partner starts by understanding what you, the client, can comfortably spend, then helps align your priorities with what is realistic in today’s market. The contractor’s construction price is only one piece of the budget. Depending on the scope, costs may also include design and architectural services, engineering and surveys, permits and inspections, demolition, disposal and dumpsters, temporary storage, landscaping, siding, roofing, asphalt, and the furnishings and finishing touches that make the completed rooms both loved and functional. For a major project, you may also need to budget for living elsewhere during construction.
Kitchens
Beyond the degree of change, the size of a kitchen, as well as cabinetry, countertop and appliance choices have the greatest impact on the final number. Keeping the sink, range and walls in place can contain plumbing, electrical and structural work; moving them can change the project substantially.
Scope Planning budget
Cosmetic refresh $20,000–$40,000
Smaller full kitchen $35,000–$60,000
Midrange full remodel $60,000–$100,000
Higher end remodel $100,000–$150,000
Luxury or custom kitchen $150,000–$250,000
Bathrooms
A bathroom refresh and a full remodel differ significantly in scope. A typical full bath remodel often begins around $30,000–$40,000. As with a kitchen, keeping the toilet, tub, or shower in place can help keep costs down.
Scope Planning budget
Cosmetic refresh: vanity, fixtures, paint, limited tile $10,000–$20,000
Small or guest bath, full renovation $18,000–$35,000
Typical full bathroom remodel $25,000–$45,000
Primary bath, mid- to high-end $40,000–$70,000
Luxury primary bath $65,000–$100,000
Moving plumbing, adding a custom tiled shower or frameless glass, heated floors, custom cabinetry, natural stone and premium fixtures can push a bathroom above $50,000. Even the cost of a single fixture matters: allow about $500 for a toilet before assuming the rest of the room is covered. Plumbing and electrical work may also require permits and inspections.
Major renovations and additions
Size alone does not tell the whole cost story. For a professionally built, finished 1,500-square-foot addition in Fairfield County in 2026, plan roughly $450,000–$825,000, or about $300–$550 per square foot. High-end, fully finished projects can reach $350–$600 or more per square foot. If the space is mostly bedrooms and family rooms, the total may sit nearer $450,000–$550,000. A new kitchen, multiple bathrooms, a primary suite, structural changes and premium finishes easily push the totals to $600,000–$800,000 or more.
Plan for the unexpected
Reserve roughly 10–15% for discoveries and changes. Doesn’t matter when a home was built, you just don’t know what the crew will find once walls and floors are open. Old pipes, subflooring or wiring may need replacement. You may decide a wider doorway improves the flow or fall head-over-heels for a sofa above the original allowance. A contingency gives you room to make necessary and indulgent decisions without too much anxiety.
Evaluating bids
When comparing estimates, “apples to apples” is critical. Set up your own spreadsheet of line items to either check off as “included” or fill in with a price.
- Are dumpsters and temp toilets included?
- Will matching siding be replaced?
- Will disturbed landscaping be fixed?
Also, if your contractor is including allowances for things like cabinetry, windows and doors, ensure the amount is sufficient to purchase the manufacturers and styles you want. The more complex or large the project the more elements to include and specify.
So, take a deep breath…Review the guidelines…Evaluate what you truly and realistically can spend on your home design project, now and over time. Then work with your designer to align your vision with both the possibilities and constraints of your budget. No reviving needed when the bids come in!
Note: Fairfield County ranges and incidental allowances are preliminary 2026 planning figures, not current vendor bids. Site conditions, scope, finishes and contract inclusions vary across every project.
