Design. Build. Beautifully Done.

A home is a thousand decisions.

Keeping track of them shouldn’t be a second job. Decco gives builders, designers, and homeowners one beautiful source for every selection, budget, and decision.

The world as it is

You already know the feeling.

i.

The tile decision

It’s on page four of an email thread, between a schedule question and someone’s lunch order. Everyone remembers deciding. Nobody remembers what.

ii.

The spreadsheet

The budget lives in a file only one person really trusts. Everyone else asks, and waits, and hopes the version they saw was the latest one.

iii.

The binder

It was right in March. It’s August now, and the truth lives partly in the binder, partly in texts, and partly in someone’s memory.

You’re not imagining it: nearly half of rework traces back to miscommunication and scattered project data. Nobody did anything wrong – the tools most teams use were never made for projects like these.

None of this is anyone’s fault.
And none of it has to stay this way.

One home, kept beautifully

Follow one home from first sketch to move‑in day.

A home being made, and the calm keeping of it, side by side.

The great room, finished Before it was a room, it was forty-one decisions: stone, timber, plaster, light. Every one of them is still on the page, with its picture and its price.

The Decco design book for a custom home: selections organized by room, with photos and prices

The design book Every selection keeps its photo, its spec, and its price, from the first idea all the way to install. The spreadsheet becomes a gallery.

Decisions become rooms The table everyone gathers around was once option two of three. The family that lives here watched it get chosen.

A project budget in Decco: activities, costs, and remaining amounts in a calm, readable table

Calm numbers The budget ties to real costs and real decisions, easy to read and easy to trust. The beautiful thing and the honest number, on the same page.

Nobody lost the thread The primary bath, exactly as it was chosen – and everyone who chose it knew, the whole way through.

The many hands

Builders, designers, and homeowners – together.

For designers

“Sharing details with my clients is the easiest part of my week.”

The selections binder comes alive: updating, pricing, sharing, all the way to install.

For builders

“Every detail has its picture, its notes, its numbers.”

The whole job, organized the way you’d be proud to hand to a client.

For homeowners

“It’s easy to follow along, easy to decide, and I always feel heard.”

Watch your home take shape, one good decision at a time.

And the trades

“I do my best work when nobody has to call me twice.”

Many hands make a home.
Decco is the one beautiful source they all work from.

How it works

Start with what you’ve got.

Connect the tools you already trust

Your QuickBooks. Your Dropbox. Soon, your Google Drive. Your spreadsheets, contracts, and task lists. Decco doesn’t ask you to abandon the tools your business already runs on.

Connect them and the project starts assembling itself: files find their projects, costs find their budgets, decisions find their place. Day one gets lighter, not heavier.

Tell Claire how you work

Claire is the intelligence inside Decco, and moving in is what she’s made for. Describe your filing system, or just tell her where things live: how you number your jobs, what a folder means at your company. She’ll suggest a filing practice proven on real homes and adapt it to yours.

And when something doesn’t fit, you get a question, not a guess.

The team behind Decco stays close while you settle in.

It takes many hands to make a home.
