Which rooms do we redesign most often when we think about our homes? And how do these choices reflect the shifting priorities of contemporary design? A recent survey, Planner 5D Reveals the World’s Most Designed Rooms — And a Comeback of Offices, attempts to answer these questions by analyzing millions of projects created online. The study, conducted by the international digital interior design platform Planner 5D, offers a map of our habits, showing how domestic spaces have evolved over the past few years.
From the kitchen to the elevator, which are the world’s most designed rooms?
A new study by the design software Planner5D reveals the most common preferences in interior design, highlighting both expected and unexpected patterns, with a few surprising results.

Planner 5D is a platform that combines digital tools with artificial intelligence, designed to make interior design accessible even to non-professionals. In addition to an intuitive editor that assists users in creating and modifying floor plans, the platform provides online courses and tutorials to learn the basics of interior design, along with a large gallery of mood boards and reference projects for inspiration.
The first ‘revelation’ is nothing short of a certainty: in the sphere of domesticity, kitchens, bathrooms, bedrooms and living rooms are confirmed - in that order - as the most ‘designed and redesigned’ rooms.
The study is based exclusively on Planner 5D’s internal data — more than 400 million projects uploaded by its users — and not on external sources or independent statistical samples. Despite this limitation, the results offer meaningful insights into how housing priorities are being reshaped on a global scale.
The first “revelation” is nothing short of a certainty: in the sphere of domesticity, kitchens, bathrooms, bedrooms and living rooms are confirmed - in that order - as the most “designed and redesigned” rooms. It is curious, but not astonishing, that kitchens and living rooms are universally at the antipodes percentages of priorities for the common home dweller: the kitchen design (estimated at 28.1%) has in fact increasingly outclassed the living room design (11.4-11.7%) over time, actually encompassing it. Indeed, there are more than one reason behind the gradual merging of these two rooms within the home hearth.
On the one hand, the increasingly shared choice of creating large open spaces, where more or less prominent open kitchens, possibly equipped with support islands of a certain spatial prominence, dialogue seamlessly with imposing full-height bookcases and with comfortable sofas, poufs and chaises longues, without too much giving importance to the possibility of culinary fragrances becoming indissolubly impregnated with the more or less valuable papers of books and magazines, or the Danish fabrics of the living area seats; on the other hand, the simplest spatial optimization, that is, where square meters are scarce, a virtue of necessity will be made, and as a result the dining table will present itself as the same perfect shelf for doing smartworking.
The fact that bathrooms turn out to be significantly more designed than bedrooms (21.2% versus 16.4%) also has a point (and Otto Wagner would have already agreed with this theory when he designed the first modern toilet in 1898, with the scandalous transparent crystal bathtub for his apartment at Linke Wienzelle 38 in Wien, and Adolf Loos, who reviewed the entire project, calling it "a jewel" and who in the same year devoted an entire essay to "The Plumbers" and their realm, understood as the bathroom and toilet); even more so, if one considers how much more interest arouses nowadays in body and skin care or in beauty routine, than in the need to rest tired limbs at the end of a busy day's work, an action for which the dimensions useful to accommodate a queen-size bed will suffice.

Still remaining within the domestic sphere, a detail that indicates a distance between European regions and the United States concerns the design of the children's room. In fact, in Europe this room ranks 7th among the most designed rooms, while in America it ranks only 12th, but this would be attributable, according to Planner5D, to a simple difference in nominal address, whereby in Europe the attitude to categorize and specify when the bedroom is intended to accommodate children seems to prevail, while in America the tendency to conventionally consider all these rooms under the same macro-category of “Bedrooms” would be more widespread.
On the one hand, the increasingly shared choice of creating large open spaces (...) on the other hand, the simplest spatial optimization, (...) as a result the dining table will present itself as the same perfect shelf for doing smartworking.
Another finding reported by Planner5D's survey considers a global sharp return to office planning and design. As an inevitable post-pandemic consequence, if between 2020 and 2024 there was a substantial increase in so-called hybrid spaces, multifunctional rooms, and home offices, it is equally plausible that once the trend died out, the average worker would have returned to banish the hypothesis of metamorphosis into a contemporary Xavier de Maistre imprisoned in the journey around his room - which, however, is also his office - returning to a preference for diversification between the domestic and professional spheres, and making manifest the need to cultivate active exchange and direct social confrontation in the physical reality, precisely, of the office.

More or less shared between Europe, the United States, and England, a miscellany of spaces such as warehouses, storage places, checkrooms, and garages hover between 7th and 18th in the ranking, while winning the record for the world's least designed space is the elevator, which, after all, back in the days of the Otis brothers, who first patented its mechanism by demonstrating its operation in 1853 at the New York World's Fair, was nothing more than a platform hooked to a spring system with a wooden frame driven by a steam engine: pure mechanisms useful for vertical movement within buildings.
In conclusion, Planner5D provides with the iconographic apparatus a table of Global Favorites, or the most frequently used furniture and decor in the Design Project (again according to the worldwide design statistics from Planner5D's 400M projects): a table with four chairs, a two-seater sofa, a cushion, a fridge, a shelf with a handful of books, a fine art print possibly depicting the Golden Gate Bridge in San Francisco (however, in black and white), a low cabinet, a tree and a bunch of fern leaves floating in the white space of the chart, a small catalog of essential items to furnish (the best?) our living space.
In this article, you will find images of some of the best interior design projects recently published on Domus.
