Choose a Scope

Scope 1 Frame only

Joiner builds the structural oak frame. You own the rest of the build including the slab, the cubby grid, the finish work, and the install.

Tool gaps

Router with flattening bit for slab leveling and cubby joints $200 – $300 new
Router sled materials built for the 3" locust slab $30 – $50 shop lumber
Tile saw for wet bay slate $50/day rental, Sunbelt Torrington
Random orbit sander for slab and cubby finishing, if not already owned $80 – $130 new

Skill stretches

Flattening a 3" black locust slab with a router sled. 8-12 hours of meticulous work. Black locust is among the hardest North American hardwoods. Easy to gouge, hard to fix.
18-cubby grid tolerance. 7 vertical dividers and 3 horizontal shelves, 21 intersections that all need to land plumb. Small errors compound.
Scribing to 1830 plaster-and-lath walls. Uneven walls and floors. Scribing is the skill that separates built-ins from furniture.
First-time tile setting in the wet bay cavity. Learnable but not your current wheelhouse.

What could go wrong

⚠ Slab flattening failureGouging or over-milling a $400-800 kiln-dried locust slab is the single biggest risk. Hard to recover without buying another slab.
⚠ Cubby grid rackingTolerance errors across 18 cells compound. The piece can end up with cubbies that aren't square, which shows in open storage.
⚠ Install day complicationsScribing to 1830 walls requires a skill you don't have yet. Expect surprises from plaster, baseboard removal, and floor dips.
⚠ LED decision not madeWiring decision (plug-in vs hardwired) still required. Hardwired triggers electrical permit.

Verdict

Lowest cost. Highest risk. Most DIY time.

This scope is right if you want to own the slab work yourself, already want to buy a router, and have 3+ months of weekends free for the build. It saves roughly $3,000 over Scope 3, but the savings evaporate if you damage the slab or need to replace a cubby grid after it racks.

The Historian's Haven brief calls for furniture-grade construction. Scope 1 asks you to deliver furniture-grade DIY work on the hardest components. Worth naming honestly before choosing.

Scope 2 Frame + bench

Joiner handles the oak frame and the black locust slab. You build the cubby grid, install everything, and do the finish work.

Total all-inSplits the cost difference

$5,600 – $9,450

What could go wrong

⚠ Cubby grid tolerance is still yours18 cells, 21 intersections, zero forgiveness on open cubbies.
⚠ LED wiring decision still requiredSame as Scope 1. Hardwired triggers a permit.
⚠ Tile setting learning curveFirst wet-bay install. Watch for improper slope and failed sealing at seams.
⚠ Install coordinationPro delivers finished frame and slab, you install both onto the cubby grid. Sequencing matters.

Verdict

Best balance on paper. Removes the hardest single component, keeps real DIY in your hands, splits the cost difference.

The original default recommendation before we stress-tested the cubby grid work. The 18-cubby grid is closer in difficulty to the slab than it looks. Scope 2 leaves you holding the second-hardest component without any of the supporting finish practice that comes with Scope 3.

Worth choosing if you want the slab handled, already own or plan to buy a router, and want to commit to the cubby grid as a teach-yourself-on-the-job challenge.

Scope 3 Full carcass

Joiner delivers and installs the entire oak structure including the cubby grid and the slab. You do the finish work that shows who lives here.

What could go wrong

⚠ Quote spread will be wideExpect a $4,000+ range across three bids. Need three bids minimum to calibrate. Do not accept the first quote.
⚠ Install day coordinationPro delivers a large assembled unit. Studio access, staging, and wall prep all have to be done before they arrive.
⚠ LED decision still neededPlug-in is simpler and keeps the permit picture clean. Hardwired means an electrician and a permit.
⚠ Shiplap and paint on a textured backing panelFarrow & Ball Green Smoke on shiplap needs clean caulk lines and 2 – 3 coats. Not hard, not trivial.

Verdict

Best tool and skill match. Highest confidence in outcome quality. Preserves the finish-work DIY satisfaction you're best at.

The cost premium over Scope 2 is real, roughly $2,000 – $4,000. In exchange, you remove the single biggest risk to furniture-grade outcome: the 18-cubby grid tolerance work. A joiner nails this in a week. A weekend DIYer with a new router accumulates small errors that show forever in open cubbies.

The brief asks for a piece that outlives the cabinet. This scope is the one most likely to deliver on that promise. It leaves you with the kind of work that makes the Studio feel like yours without betting the outcome on skills you don't yet have.

What breaks the decision

These five items cross all three scopes. Any of them can flip the math or push the project backward. Close each one before you sign a contract.

LED wiring path still open Plug-in keeps the build permit-free and adds zero electrician cost. Hardwired under-cubby lighting triggers an electrical permit and a licensed trade call. The decision affects cost on every scope and the permit timeline on Scope 2 and 3.
Oak stain reference not locked Minwax Jacobean, Old Masters Dark Walnut, and General Finishes Dark Chocolate all read differently on rough-sawn oak. The contractor needs this specified before the frame is finished. Ordering a sample board before the contract signs is faster and cheaper than color-correcting on a 102" post.
Permit classification from the Town Call the Litchfield Building Department to confirm a built-in mudroom is treated as built-in cabinetry, not structural work. Confirmation changes what the contractor can do, who pulls which permits, and whether you need an architect's stamp. Blocked on the LED decision above.
1830 wall surprises on install Plaster-and-lath walls are rarely plumb and rarely structurally consistent. Scope 1 and 2 put the scribing and anchoring in your hands. Scope 3 puts it on the pro, but still depends on studs behaving. Budget a contingency for wall repair across all three scopes.
Contractor vetting floor Three bids minimum. CT HIC license verified on all three. Portfolio has furniture-grade M&T work, not just cabinetry. References spoken to directly, not just listed. Scope 3 with a bad joiner is worse than Scope 1 with a great weekend.
