Store 3D Layout

A 2D floor plan became a walkable 3D stand, so merchandisers could review every room set, sightline and aisle before a single fixture was built.

The Challenge

A flat plan can't sell a bedroom

The stand had to tell eight collection stories in 364 m². The team was planning it from a 2D floor plan and a handful of renders.

Plans hide the story

A 2D drawing showed where beds go, not how a buyer walks from Good to Best or what they see first from the aisle.

Adjacencies by email

Which collection faces the aisle, where licensing sits next to hospitality: debated in long threads, without a shared view.

Renders: few and slow

Each agency render showed one fixed angle. Every change to a room set meant waiting days for a new image.

Surprises at build-up

Blocked sightlines, tight aisles and signage heights were often found on site, when changes cost the most.

HMC Approach

Walk it before you build it

The floor plan stayed the source of truth. GenAI turned it into a space the whole team could walk through together.

Select a step to see what happened.

Discover · Start from the plan and the story

We gathered the January floor plan and the merchandising brief.

  • Floor plan with columns, room sets, walls, meeting rooms and back of house.
  • Collection list and the story each zone had to tell: House brand, licensing, Grand Hotel, Estate and more.
  • The buyer journey: arrival, aisle, room sets, hospitality, meeting.

Deliverable: Plan, collection brief and buyer-journey map.

Design · Scale, zones and camera views

We fixed the rules so the model stays faithful to the plan.

  • Scale read from the drawing: a queen bed is about 140 px, so 100 px = 1 m.
  • Dressing standard for every room set: bed, duvet, pillows, headboard, bench and rug.
  • Camera views that follow the buyer: overview, plan, aisle, kids, room sets, hospitality.

Deliverable: Scale rule, dressing standard, view list.

Build · GenAI turns coordinates into a stand

Claude wrote the model as a single web file, straight from the plan's coordinates.

  • Twelve dressed beds, two lounges, tiered towel walls, shelving and a six-seat hospitality bar.
  • Brand signage and header banners; back offices and kitchen as a toggle layer.
  • Labels for every zone and a legend of room sets, colour-matched to each collection.

Deliverable: Home textiles stand model, browser-based, no install.

Adopt · Review in the model, not the inbox

Merchandising, sales and leadership reviewed the stand together, on screen.

  • Live walkthroughs from the aisle view; adjacency calls made in the room.
  • Changes updated in the model the same day and re-shared as one link.
  • The final version briefed the stand fabricator alongside the 2D drawing.

Deliverable: Signed-off layout and a fabricator briefing pack.

Scale · From stands to stores

The same method now applies to showrooms and retail floors.

  • Template reused for future trade shows and showroom refreshes.
  • Extending to retail store layouts and fixture planning.
  • Merchandising team trained to brief and review new models.

Deliverable: Model template and prompt pack.

The Solution

The actual stand. Walk it.

This is the model as delivered. Drag to orbit, scroll to zoom, and use the view buttons to jump to the aisle, kids licensing, room sets or hospitality. Toggle labels, back offices and signage.

Faster sign-off, fewer surprises

Reviewing in 3D cut the back-and-forth. The problems that used to appear at build-up surfaced on screen instead.

Key Takeaways

What transfers to any retail or showroom team

01

Walk it before you build it

Moving through the space surfaced problems a plan view never shows: blocked sightlines, pinch points, hidden collections.

02

Keep the plan as the source of truth

Building from the drawing's own scale kept the model honest. Reviewers trusted it because it matched the plan.

03

Design the views around the buyer

Camera views that follow the buyer's route turned a layout review into a rehearsal of the customer visit.
