Financial Clarity for Seattle Residential Development.
Seattle residential development is a project-by-project business. Bivvit reviews the projects you already finished so each one teaches you something.
See how construction costs, timing, sales, financing and profit compare across your completed developments.
Bivvit is an analysis service. We do not develop property, list homes, lend or build — we review the documents your finished projects produced and explain what they mean.
Free. Send one project to start.
Understand every Seattle project
Most Seattle builders run more than one product type at a time. A townhome site, a small-lot house, an SFR with a DADU in the back. Each one carries a different cost structure, a different construction period and a different buyer. Bivvit keeps them in one place so you can see them next to each other instead of one budget at a time.
Townhomes
Cost per unit and cost per SF across sites, plus how unit count changes the economics.
SFR
Single-family builds compared by size, neighborhood and construction period.
SFR + ADU
Shared site costs allocated between structures so each one carries its real cost.
SFR + DADU
Detached unit cost per SF, utility exposure and whether the second structure earned its cost.
Cottage housing
Multi-structure sites where site work and utilities move the whole project.
Small-lot and missing middle
Tight sites, higher per-SF costs, and how they compare with your larger builds.
Know your cost per square foot
One project budget is not a benchmark. It is a single observation. Bivvit lets you compare cost performance across projects you have actually built, so the number you use on the next site comes from your own history rather than a guess.
- Hard cost / SF
Construction cost per square foot, held to a consistent definition across every project.
- Total project cost / SF
Hard costs plus soft costs and financing, so you can see the number that actually determines profit.
- Budget versus actual
Where each cost category landed against the budget you started with, project by project.
- Cost trends
Whether a category is drifting over time or a single project pulled the average.
- Historical performance
Completed projects as an underwriting input for the next land acquisition.
- Product type differences
Townhome, SFR and ADU or DADU costs kept separate rather than blended into one meaningless average.
Learn from every project you finish
The project you just closed out holds the most useful information you own. It tells you what your framing really costs, how long your permits took, what your utilities ran, and what the market paid you for the result. That belongs in the next land deal and the next construction budget.
See your entire Seattle portfolio
Looking at projects independently hides the pattern. A single job report tells you what happened on that job. Builder-level analysis tells you which decisions your company keeps getting right and which ones keep costing you money.

What makes a Seattle comparison honest
Bivvit starts with your own completed-project history. Broader market comparisons should only be used when the projects and definitions are genuinely comparable — national averages blend markets and product types you would never build.
Geography and neighborhood
City, submarket and neighborhood, because site conditions and buyers differ block to block.
Product type and units
Townhome, SFR, ADU or DADU, and how many units the site carries.
Project size
Square footage, so a 1,400 SF house is not measured against a 4,000 SF one.
Construction period
When the work happened, since pricing moves year to year.
Cost and duration
Cost per square foot alongside how long the project took.
Profit margin
Margin measured the same way on every project in the group.
Compare like projects with like projects.
