For Custom Home Builders

Stop losing seven-figure custom builds to your three-ring-binder proposal.

12 trades, 47 selection allowances, change orders in three email threads, the architect's plans on a Dropbox link nobody can find. Glewit ships your custom-home proposal as one branded document, pulls it forward into the contract, and closes the build with a handover packet that ties every allowance and warranty to the unit they belong to. Free trial. Custom-home catalog included.

The proposal that should take a week takes three weeks. The build runs 9 months past the date in the contract anyway.

You're rebuilding the same allowance spreadsheet for the fourth time this month, the homeowner is asking which version of the kitchen number is real, the change order for the regraded site is buried in an email thread, and the architect just sent revised plans you'll forward to nine subs by hand. Every build, the proposal eats a week of nights and still goes out looking like a binder. And the one thing the homeowner remembers at the end isn't the house — it's that they never quite knew where the money went. The build was never the problem. The paperwork was.

Proposal → Contract → Handover

Project data flows forward — enter it once, render it three ways. Every field on the proposal carries through to the contract and the handover packet.

01 · Proposal
Custom Home Builders proposal page preview

The whole build on one page — the GC work itemized by milestone (foundation, framing, dried-in, MEP rough, drywall, completion) and every selection trade set as an allowance the homeowner picks within. Roofing, windows, HVAC, the kitchen, the baths, flooring, landscape — all in one branded document, not nine disconnected bids. Same home, three spec tiers.

02 · Contract
Custom Home Builders contract page preview

The three things that run a custom build, in writing (§15): the milestone schedule and how weather days and re-baselining work, the selection allowances with the over-and-under rules, and the change-order discipline — written and signed before the work, reconciled at every billing.

03 · Handover

One packet for the whole home — every warranty and registration across the five categories (structural & envelope, MEP, interior finishes, site & landscape, high-performance), the allowance reconciliation, the as-built plans, the certificate of occupancy, and any energy certification. Closed out, not just finished.

Questions custom home building contractors ask

Does Glewit handle selection allowance management across 8+ trades?
Yes — that's the core of it. Every homeowner-selected trade (roofing, windows, HVAC, kitchen, baths, flooring, lighting, landscape) is an allowance line, included in the total, with the over-and-under rules in plain language. When a pick comes in over, it's a change order; under, it's a credit. The running total stays current instead of living in a spreadsheet you rebuild every week.
Cost-plus, GMP, or fixed-price — which does Glewit support?
All three. The proposal and contract carry whichever structure you run — cost-plus with a fee, a guaranteed maximum price, or fixed — and the allowance and milestone schedule work the same way underneath. You set the contract type; Glewit handles the document.
How does Glewit handle change orders — the universal custom-home headache?
Written, priced, and signed before the work proceeds — no verbal authorizations that turn into a fight at the final invoice. Each change order ties to the build and reconciles at the next milestone billing, so the homeowner always knows the current number. It's the §15 change-order discipline, built into the document instead of scattered across email.
Does Glewit play nicely with my architect's AIA-document workflow?
Yes. Where an AIA owner-architect (B141) or general-conditions (A201) document governs the architect relationship, your Glewit contract reads alongside it — and the architect's plans, RFIs, and revisions live with the proposal instead of on a Dropbox link nobody can find. ConsensusDocs works the same way if that's your framework.
Can the catalog handle Passive House, LEED, or Net Zero builds?
Yes — high performance is an optional overlay. When a build targets Passive House (PHIUS+), LEED, Net Zero Energy Ready, or ENERGY STAR Most Efficient, the catalog carries the energy-modeling and certification allowance, the ERV/HRV system, and the solar-ready prep. On the builds that aren't chasing a cert, the overlay just isn't there.
Subcontractor coordination and insurance verification — first-class or bolt-on?
First-class. The orchestration layer is the whole point: you run the GC-controlled work directly and the allowance trades through subs, and the contract covers verifying each sub's license and insurance before they start. The proposal shows the homeowner one coordinated build, not nine disconnected bids.
Does the milestone payment schedule tie to the inspection sequence?
Yes. The schedule bills at milestone completion — foundation, framing, dried-in, MEP rough, drywall, substantial completion, final — and each milestone is sequenced around the AHJ inspection it depends on. Milestone is the unit of account, the way custom builds actually get paid.
Whole-home warranty handover — every trade's registration in one packet?
Yes — the handover packet collects and registers every manufacturer and sub-trade warranty across the build, plus the as-built plans, the allowance reconciliation, the certificate of occupancy, and any high-performance certification. One packet for the whole home, not a shoebox of receipts the homeowner loses by year two.
