The business in one offer
Who it serves
Homeowners with a fireplace alcove or blank living room wall who want storage that looks original to the house. They are usually not planning a full renovation, have books or display pieces to house, and will pay for a single built-in project done in a few days rather than a long kitchen-style remodel.
What to sell first
One paint-grade bookshelf built-in, up to 8 feet wide and 8 feet tall, with adjustable shelves, an optional lower cabinet section with two doors, face frames and crown trim, painted in the client's chosen color. Excluded: lighting or electrical work, moving outlets, stain-grade hardwood, glass doors, and any wall or floor repair beyond trim.
Limiting the work to one wall, one material and a paint finish keeps the design simple and the shop process repeatable. You can price by linear foot with a few add-ons, and customers can see a finished sample corner instead of a drawing, which shortens the decision.
What could it cost to start?
This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.
| Item to price | Example allowance |
|---|---|
| Jobsite table saw and track saw | $950.00 |
| Paint sprayer and masking supplies | $380.00 |
| Scribing tools, levels and shims | $160.00 |
| Sample corner cabinet for sales visits | $260.00 |
| Liability insurance first payment allowance | $800.00 |
| Dust masks, extraction hose and drop cloths | $200.00 |
| Example total | $2,750.00 |
What this assumes—and excludes
Assumes a garage shop with power, a van or truck for panels, and cabinet-making experience. Excludes shop rent, contractor or home improvement registration fees, lead-safe certification costs, workers' compensation and owner pay. Get local quotes and check registration rules before taking deposits.
Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.
How the unit economics work
At an assumed $3,200.00 per built-in project and $900.00 in direct costs, contribution is $2,300.00 before monthly fixed costs, owner pay and taxes. With 38 all-in working hours per unit, that is $60.53 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.
The example also allows $250.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.
Try your own numbers
These are editable planning assumptions, not prices we have verified. Calculations stay in your browser.
Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 380 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.
How to find the first customers
Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.
- Bring the sample corner cabinet to two interior designers and one real estate stager and show the paint finish up close. Ask what wall projects they hear about and agree how referrals will work.
- Photograph the first two projects before and after, with the owners' permission, and post them with the size limits and starting price on your website so leads arrive already qualified.
- Leave a short printed sheet at a local paint store counter, if the manager agrees, explaining that you build the shelves and coordinate with the client's chosen paint color.
- Ask each finished client whether they would accept a short call from one future prospect who wants to hear about the process. Never write reviews for clients or offer payment for ratings.
What to validate before spending more
- Build one built-in for a friend or relative and log hours for design, shop work, finishing and install. Compare that total to the per-foot price you planned.
- Ask your state whether home improvement or contractor registration applies to built-in installs, and whether your city requires a permit when no electrical work is involved.
- If you will work in homes built before 1978 and remove or cut painted trim, check EPA's lead renovation rules and get the required firm and renovator certification first.
- Get quotes for two paint-grade plywood sheets and a finish system from two suppliers, and test the paint on a sample panel for curing time before you promise install dates.
The operational catch
Most quotes miss the hours lost to walls and floors that are out of square. Boxes built to a tape measure may leave visible gaps or rock on a sloped floor. Build boxes slightly smaller than the opening, add scribe strips and adjustable bases, and charge a fixed amount for trim removal and reinstall so the hours are paid.
A practical way to fund the first step
Take a 40 to 50 percent deposit at contract to cover plywood and finish, a second payment when boxes are built, and the balance at install. Rent the sprayer for the first project and buy it once the next two jobs are signed.
Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.
Questions before you start
Should I paint in the shop or in the house?
Shop painting gives a smoother, more even finish and keeps fumes out of the client's home. Site painting lets you fill nail holes and caulk seams after install. Many makers prime and paint in the shop, then do a final touch-up coat on site.
How do I price built-ins?
Start with a price per linear foot for open shelving and add fixed amounts for lower cabinets, doors and crown trim. Keep the add-on list short so you can quote at the first visit without a long design process.
What if the client wants lighting?
Leave electrical work to a licensed electrician hired by the client or coordinated separately. You can plan the cabinet so wiring channels fit, but do not wire fixtures yourself unless you hold the right license.
