A specialty coffee shop is a commercial interior optimised for the twenty-minute visit. The five paintings below are chosen for that audience: paintings that register from across the room while the visitor is ordering at the counter, reward a second look from the seated position at the small table, and survive the warm pendant lamp-light most specialty cafes use after sunset.

A hotel lobby is the rare commercial interior where wall art is read by a moving audience at varying distances over a four-to-fifteen second window. The six paintings below are chosen for those constraints: a large legible compositional centre that registers from across a check-in counter, a palette that survives both daylight from the entrance and warm evening lamp-light, and subject matter that signals the hotel's positioning without describing it in words.

A fine-dining room is one of the hardest spaces in commercial interior design to dress. The lighting is low, the conversation must be the loudest sound, and the wall art has to read at a distance of three to twelve metres from a seated guest while staying invisible enough that no one accidentally describes it as the reason they came. Six paintings from the European canon are unusually well-suited to this brief.

A co-working wall has to do two jobs at once: inspire people who came in to think, and stay quiet enough not to compete with their laptop screens. Seven paintings that hold the balance, and the composition rules that keep them out of the way.

The art on a dental office wall has one job: lower the pulse rate of the person looking at it. Six paintings that do, why they do, and how to compose a waiting room around them.

A boutique hotel earns its premium not from the linen, the espresso machine, or the rain shower — it earns it from the moment a guest walks into a guest room and feels they have arrived somewhere specific. The art on the walls does more of that work than any other single design choice. A bad print on the wall above a bed cancels a thousand euros of mattress quality. The right painting above the same bed makes the room hold a guest for an extra night. Below are seven anchor pa

A hotel lobby has six seconds to read. Six seconds for a guest crossing from revolving door to reception desk to register: is this somewhere serious. The art on the wall behind reception, or above the lobby fireplace, does the work no marketing collateral can. Seven paintings hold a hotel lobby better than almost anything modern. Here is the operator brief — what to hang, what size, what frame, against which wall colour. What hotel lobby art has to do Lobby art serves three
