Whole-home remodel cost: what affects what you will pay
A whole-home remodel's budget is a stack of components that become reliable at different moments. This page explains each part, what a bid should include, and when a figure stops being a guess.
Cost and budget
What a budget is made of, and when it becomes real.
Cost components, what a bid should include and how to compare proposals for each service. KB does not publish a price list: a figure only means something once the house, the scope and the drawings are known.
01
By service
Detached ADU cost: what affects what you will pay
A detached ADU is a new building on an existing lot, so site work and utilities weigh as much as the structure. This page explains each component and when its number becomes reliable.
Garage conversion cost: what affects what you will pay
Converting a garage reuses an existing structure, so its condition decides much of the budget. This page explains what to check, what a bid should include and when the figure becomes reliable.

Budgeting ahead: base dates and scenarios
If your work will start in 2027 or later, a quote today has a base date and a validity period. This site publishes no future prices. The budget guide explains estimate maturity, quote validity and how to avoid escalating twice; here you can test your own assumptions. Full method in the budget guide
Compare your own escalation assumptions
Enter only the cost categories you expect to change with time, priced at a known base date. Leave out land, fees already paid and anything already priced at the later date. Nothing is saved or sent.
Hypothetical presets — not forecasts:
Enter all three values to see a scenario; blanks stay unknown.
A hypothetical arithmetic scenario from your inputs. It is not a KB price, a market forecast or a contractor quote. Do not escalate a contingency that already allows for price change.
Principles on every cost page
- Components, not totals: design, engineering, agency fees, construction, finishes, allowances and contingency are explained separately.
- Agency fees come from each authority's own published schedule; we link the authority rather than quote numbers that change.
- Examples are illustrative and never describe a client or a KB project.
