Problem

Renovators stall mid-project because no tool tells them what to do next.

Homeowners plan across Pinterest, SketchUp and a spreadsheet, and lose momentum at every switch. A designer costs $1,000 to $10,000, which puts the alternative out of reach for most of them.

Competitive landscape

Four existing planners, audited on the five things a renovator needs — no tool covered more than three. The ArchDzyn column is the design brief, not an audit result.

Process + Evidence

Five participants, recruited from friends and family, each worked through the prototype against IKEA Planner and SketchUp with responses captured in a structured form. Five is enough to surface problems and not enough to prove a rate — and a sample drawn from my own circle cannot stand in for the market — so nothing here is stated as a rate.

Decision

Bottom nav ordered by frequency, not category — Surfaced by testing, then changed

Tabs ordered by how often they get used
Tabs ordered by how often they get used

The first build ordered tabs by category, which is tidy and wrong. Watching five people use it showed which tabs they reached for constantly and which they never opened, so the order now follows usage.

Decision

Start from a mood board

InspoHub into the Design Room

For people who know how they want a room to feel before they know what it costs. Saved inspiration goes straight into the design room, aesthetics first.

Decision

Start from a budget — Fewer abandons late in the flow (n=5)

Budgeteer into InspoHub into the Design Room

Setting a ceiling first means every later choice filters against it, instead of a plan collapsing at the quote stage. This was the entry point testers finished most often, on a sample of five.

Decision

Start from a spec

Design Room into Budgeteer

For people who already have measurements and want to skip inspiration entirely. Straight into layout, with cost accruing as they place things.
