Retail & Showroom Interior Design.
Sightlines, fixtures, lighting, and statement pieces that make merchandise sell — from a dealer that designs and runs its own showrooms. Metro Detroit and nationwide. Since 1985.
How do you design a retail showroom layout?
Written for store owners, brand teams, and franchisees — the people who answer for what a square foot of floor earns.
Retail interior design choreographs how a customer moves: sightlines from the entrance, a path that builds dwell time, fixtures that flex with seasons, and lighting tuned to the merchandise rather than the room. A showroom layout works when the space itself becomes the strongest argument for the product.
That is a claim we make from experience rather than theory. Italcasa designs, merchandises, and re-sets two of its own showrooms — the same floors, the same seasonal resets, the same argument about where the statement piece goes. Retail sits inside commercial interior design, but it is the one sector where we are also the client.
We specify the layout, the fixtures, the lighting, and the pieces that stop foot traffic — then import and install them with the team that wrote the specification. Since 1985.
Retail Interior Design Is Measured in Linear Feet, Not Square Feet.
A store is counted in fixtures and the merchandise they hold, and it has to be re-merchandised four times a year by staff who were not there when it was designed. Six constraints shape every retail specification we write.
- Linear Feet
The unit of work is the fixture.
Not square footage — linear feet of display and the merchandise each foot has to hold. Scope, budget, and phasing are counted against fixture runs, because that is the number that translates into how much product is on the floor and how much of it a customer can see from where they are standing.
- Sightlines
The first ten feet decide the visit.
Customers need a decompression zone inside the door before they will look at anything, and then one clear sightline deep into the space. Get that wrong and the back half of the store never gets walked. Layout starts at the threshold and works inward, not from a plan view.
- Dwell
Path design is what you are actually buying.
A good floor slows people down without trapping them: a route with reasons to stop, sightline breaks that reveal the next thing, and room to browse without standing in someone else's shot. Dwell time is the metric behind every layout decision we make.
- Flexibility
The floor changes four times a year.
Fixtures are specified so a seasonal reset is a two-person overnight job — modular runs, movable display tables, adjustable shelf heights, and nothing so bespoke that a new merchandising plan requires a new fixture order. A store that cannot be re-set gets re-set badly.
- Lighting
Light the merchandise, not the room.
Ambient level, accent ratio, color temperature, and color rendering are chosen against what is being sold — fabric, metal, food, and skin all want different light. A high-CRI accent scheme on the product with a quieter ambient layer is what makes a finish read the way it did in the sample.
- Access & Egress
The path of travel is not negotiable.
ADA clearances between fixtures, accessible checkout and fitting-room routes, and egress widths survive every merchandising change — so they are drawn into the fixture plan rather than checked afterwards. Landlord tenant-improvement review looks at this first.
- Codes & Standards
What we specify against.
Checked before the order is placed, and documented in a form your landlord's tenant coordinator and the building department can both read.
- ADA and ANSI A117.1 accessible routes, fixture clearances, checkout and fitting-room requirements
- Egress width, aisle clearance, and occupant load for mercantile occupancies
- Landlord tenant-improvement criteria and lease-required design review submissions
- CAL 117 flammability on upholstered seating in lounge, fitting, and consultation areas
- Lighting: color rendering and temperature specified to the merchandise, plus energy-code compliance
- Fixture loading, anchorage, and seismic or wall-attachment requirements where the jurisdiction calls for them
The Path, the Fixtures, and the One Piece People Photograph.
Layout and merchandise planning come first, because everything else is downstream of where a customer stands. Then the fixtures that hold the product, the lighting that makes it read, and the statement piece that gets the store shared.
Layout & customer-path planning
Entry decompression, primary sightlines, the route through the space, and where the floor slows down — drawn against the merchandise plan rather than the empty shell.
Fixture and display specification
Display tables, plinths, shelving runs, and cases specified in linear feet, with adjustability and modularity written into the package so a reset does not need a reorder.
Statement furniture and installations
The one piece a store is remembered for and photographed in front of — chosen to belong to the brand rather than to interior-design fashion, and placed where it is visible from the sidewalk.
Merchandise lighting design
Ambient and accent layers, color temperature and rendering matched to what is on the shelf, and dimming so the floor reads the same at opening and after dark.
Window and focal displays
The window as the store's only advertisement to people already walking past — fixture, light, and one object, changeable by staff on a schedule.
Rollout consistency across locations
One specification, one finish schedule, one fixture package, repeated per store — with substitutions documented so location four matches location one.
Seasonal reset support
Fixture kits, storage planning, and a reset guide written for the staff who will actually do it, so the floor still looks designed in month nine.
Every fixture specified so a two-person crew can change the floor overnight without a designer on site.
Scheduled Backwards From Opening Day.
A store opening is a fixed date with rent already running against it. The gates are the landlord's tenant-improvement approval and the certificate of occupancy, and a fixture package on a European lead time has to be ordered long before either one lands. We work the calendar in reverse.
- 01Kickoff
Floor Walk & Merchandise Plan
We walk the space or the shell drawings with you and start from what you sell and how much of it is on the floor — categories, adjacencies, linear feet needed, and the opening date everything is scheduled against.
- 02Design
Layout, Fixtures & Light
Customer path, fixture plan in linear feet, lighting scheme, and the statement pieces — presented with real finish samples, and written so it can be repeated at another location without being redrawn.
- 03Lead Time
Order, Import & Staging
Orders placed against the opening date, with European production and freight built into the schedule rather than discovered late. Customs, receiving, and inspection are ours; the package is staged complete before anything ships to the store.
- 04Install
Install, Then Merchandise
Fixtures and lighting installed in one coordinated window, with the floor handed over early enough that your team can merchandise it properly — the step retail schedules always compress and always regret.
We Run Two Showrooms of Our Own.
No competitor on this page can say it. Our floors are designed, merchandised, lit, and re-set by the same team that would do yours — which means the portfolio is a place you can walk through on a Tuesday morning instead of a PDF we email you.
Royal Oak
A retail floor we design for ourselves and re-merchandise through the year — the layout argument, the lighting scheme, and the statement pieces are all decisions we have had to live with rather than hand over.
- Sightlines and path planned from the entry, then revised against how people actually walk it
- Fixtures and display tables re-set seasonally by our own team
- Accent lighting tuned to finishes — the same scheme we specify for clients
Troy
A trade-facing floor inside a design center — a different customer, a different path, a different merchandising rhythm, and a useful demonstration that the same method scales down to a focused footprint.
- Compact footprint merchandised for a trade visitor with an appointment, not a browser
- Contract library and finish samples integrated into the floor
- The same specification method we bring to client stores, practiced weekly
Statement Retail Furniture, Glass Display, and Light That Sells.
A store gets remembered for one object and photographed for the same one. We hold the dealer agreements for the houses that make those objects — and for the quieter pieces around them that let the merchandise stay the subject.
Pieces that stop foot traffic
The object a store is photographed for.
- Seletti
Irreverent, instantly recognisable objects that do the work of a window display on their own — the piece a customer photographs and a passer-by walks in to look at.
- Gufram
Pop-art seating and sculpture with genuine collector status. One placed well is a focal point no fixture package can buy.
- Moooi
Signature lighting and furniture with gallery presence — scale and drama for a double-height entry or a feature wall, from a house customers already recognise.
Glass, plinths, and tables
Retail display tables that hold weight and light.
- Tonelli
Glass consoles and display tables that carry product without visually carrying anything — the merchandise stays the subject, which is the whole job of a display surface.
- Sovet
Glass and metal tables in a deep finish range, sized and repeatable across a floor — useful when a fixture run has to look intentional rather than modular.
- Slide
Illuminated indoor and outdoor pieces — seating, plinths, and bar units that light themselves. Strong in windows, pop-ups, and event activations where power is easier than a lighting track.
Accent and architectural light
Where the merchandise gets its color back.
- Flos
Architectural track, accent, and decorative fixtures in one house — so the working light on the merchandise and the visible light in the room can actually be coordinated.
- Vibia
Architectural lighting families with consistent geometry across pendant, wall, and linear — useful for holding a lighting language across a multi-location rollout.
- Marset
Warm decorative light for consultation corners, fitting areas, and the softer edges of a retail floor, where the room should stop feeling like a store.
One Fixture Spec. Shipped and Installed Per Location.
A second store in another state should not be a second design project. We write the package once, hold the drawings and the finish schedule, and repeat it per location — so store four still looks like store one, and the crew in Nashville installs from the same documents as the crew in Troy.
Plan review and video floor walk
You send the shell drawings, the lease exhibit, and the merchandise plan, or we walk the space on camera with your store or brand team. We work from the same documents your architect and landlord have.
Specification package built to repeat
Layout, fixture schedule in linear feet, lighting, and finishes — documented so a second and third location can be built from the same package rather than designed again.
Samples shipped to you
Finish, fabric, and fixture-material samples couriered to the store or the brand office, so the decisions get made against the real thing under your own lighting.
Freight and white-glove install per location
We manage factory orders, import, and freight, then coordinate local white-glove crews into each store on its own schedule — with the same specification and the same finish schedule in every city.
Retail Interior Design in Metro Detroit — and Wherever You Open Next.
Come stand in the thing we are proposing. Our own floors are the best brief either of us will get: you can see how a sightline is held, how a display table takes weight, and what the lighting does to a finish at eleven in the morning versus six at night.
Retail and showroom questions.
What store owners and brand teams ask in the first meeting — answered the way we would answer them on the floor.
How do you design a retail showroom layout?
It starts at the threshold. A customer needs a few feet of decompression inside the door before they will look at anything, then one clear sightline deep into the space so the back half of the store gets walked. From there the floor is planned as a path with reasons to stop — focal pieces at sightline breaks, browsing room that does not put people in each other's way, and fixture runs sized in linear feet against the merchandise plan rather than the square footage. Accessible routes and egress are drawn into that plan from the start, not checked at the end. Then lighting is layered on top: ambient low, accent on the product. We design our own showrooms this way and re-merchandise them ourselves, which is the fastest way to learn which parts of a layout survive contact with real customers.
What lighting works best for retail merchandise?
Two layers, and the merchandise decides both. A modest ambient level keeps the room comfortable; a high color-rendering accent layer on the product does the selling, typically at a noticeably higher intensity than the ambient so the eye goes where you want it. Color temperature is chosen against what is on the shelf — warmer light flatters wood, textile, food, and skin; cooler, crisper light suits metal, glass, and technical product. Dimming matters more than people expect: a floor that reads well at eleven in the morning behind a glass storefront needs a different setting after dark. We specify accent, track, and decorative fixtures from the same houses so the working light and the visible light are coordinated rather than fighting.
How do you keep multiple store locations consistent?
By writing the specification to be repeated. One fixture schedule, one finish schedule, one lighting family, and drawings held on our side so location four is built from the same documents as location one — with any substitution documented and approved rather than decided locally. We hold the dealer agreements for the houses in the package, which is the practical part: the display table in store one is still orderable for store four, and the finish still matches. Freight and white-glove installation are coordinated per location on each store's own schedule, from Metro Detroit.
What furniture makes a showroom memorable?
One object, placed where it can be seen from outside. Statement pieces from houses like Seletti, Gufram, and Moooi are specified for exactly that job — they are recognisable, they photograph, and they give a customer a reason to come in and a reason to post about it afterwards. Around that, the display furniture should recede: glass and metal tables from Tonelli and Sovet hold product without competing with it. The mistake is spreading the drama evenly — a floor where everything is a statement reads as a showroom for furniture, not a store for what you sell.
Do you design stores outside Michigan?
Yes. Our showrooms are in Metro Detroit and we specify and install stores nationwide. A remote retail project runs on plan reviews and video floor walks, a specification package built to repeat across locations, samples shipped to your store or brand office, and then import, freight, and local white-glove installation coordinated by us into each location's own build schedule.
