She sent her kitchen drawing to Reform, and selected the companyâs most expensive option â the bronze doors by Norm Architects, paired with concrete counters with waterfall edges and an integrated sink. The cabinet fronts, toe kicks and panels for integrated refrigerator drawers and a dishwasher cost about $5,000. Counters for a bank of cabinetry and an island cost about $8,500.
The resulting look stands up to other high-end designer kitchens, Ms. Keogh said, but in terms of price, âit was a massive difference.â Estimates from the other companies had ranged from about $40,000 to $80,000.
Reform is focused not only on Ikea hacking, the do-it-yourself repurposing of Ikea products to serve other functions, but on decidedly upscale upgrades â call it Ikea bling. It is one of numerous companies now building businesses around the notion of giving Ikea products more aesthetic diversity and appeal. Others offering doors for Ikea kitchens, without Reformâs big-name collaborators, include Semihandmade, Dunsmuir Cabinets and Kokeena. For furniture, companies like Swedenâs Bemz are making beautiful slipcovers with designer-grade fabric for Ikea sofas and chairs.
Jeppe Christensen and Michael Andersen founded Reform in Copenhagen in the fall of 2014. Both had previously sold custom kitchens, and saw a hole in the middle of the market between basic and bank-account-burning options.
âWhen you do kitchens, you know the dilemma â Ikea does good quality, and all the rest do design, but theyâre expensive,â said Mr. Andersen, standing in Reformâs New York showroom, which opened in May in a space near the Brooklyn Navy Yard painted in gray and white.
Ikea uses the same Blum hinges, drawer slides and other hardware as many high-end kitchen manufacturers, he added.
Inevitably, Mr. Christensen said: âWe would tell the client, âYou can save half if you use Ikea carcasses, and we just skin it.â Thatâs where the initial idea started.â
Sensing that there was a bigger business opportunity than producing a few one-off kitchens, they discussed the concept for Reform over a beer and soon compiled a list of three collaborators that represented their Danish design dream team: BIG, Henning Larsen and Norm.
âWe never imagined they would all say yes,â Mr. Andersen said.
But they did, and Reform introduced its first architect-designed collection in August 2015. (The company also offers a kitchen designed in-house).
The company sold about 200 kitchens in 2015, 500 last year, and is on track to sell 1,000 this year, to homeowners in more than 20 countries, Mr. Christensen said. About 10 percent of Reformâs sales have been in the United States.
The company recently expanded into furniture, including a credenza designed by the Swedish firm Afteroom with fluted doors over Ikea guts. It has also introduced more kitchen designs, including one with full-height ash handles and rails by the Danish designer Chris L. Halstrom, and another with aluminum fronts and integrated pulls by the Berlin-based architect Sigurd Larsen. Yet another new kitchen design by the restaurateur Claus Meyer and his wife, Christina Meyer Bengtsson, is scheduled to be introduced this fall.
So far, the founders have had little contact with Ikea, except for a letter from the companyâs lawyers.
âIt was the nicest letter ever from their lawyers, saying, âItâs fine, you can do whatever, just remember that we have a registered trademark,â â Mr. Christensen said. (There is now a disclaimer buried deep in Reformâs website indicating that the company is not affiliated with Ikea).
Indeed, Ikea appears to be actively encouraging the development of products from other companies that expand on its core collections.
As Marty Marston, a public relations manager at Ikea, put it: âOther companiesâ building on our concept and range proves the strength of our offer and addresses our customersâ wish for personalization. We welcome co-creation as it makes the Ikea offer richer.â
In April, the company introduced Delaktig, its concept for a transformable bed-sofa by the British designer Tom Dixon that invites outside companies to make add-ons. For the prototype, Ikea partnered with Bemz to create an intensely shaggy slipcover from brownish-black Icelandic longhaired sheepskin.
Lesley Pennington, the founder of Bemz, likened the Delaktig cover to âhaute couture.â Her company carries more than 300 fabrics, including some used by professional interior designers, such as textiles from Designers Guild and Romo. They can be ordered as covers for more than 100 models of Ikea furniture, with sofa covers starting at $99 and running well past $1,000.
âOur customers can take a piece of mass-market furniture and create something that is personal and unique,â said Ms. Pennington, noting that Bemz sells 3,000 to 5,000 covers a month to customers in 42 countries. âWe have beautiful cottons, linens and velvets. Some people actually purchase an Ikea sofa for the first time because of the opportunity to purchase a cover from Bemz.â
Products from Ikea, which reported sales of more than 35 billion euros (about $42 billion) for its 2016 fiscal year, are becoming so ubiquitous that Ms. Pennington sees some parallels between the emergence of companies like Reform and Bemz and the developers of iPhone apps.
âThis whole ecosystem around Ikea products is something quite unique in the furniture industry, but weâve seen it in the technology industry for a long time now,â said Ms. Pennington, who worked at Apple before founding Bemz.
Just as app developers have given the iPhone new functions, these furniture companies are giving Ikeaâs utilitarian offerings an unforeseen sense of style in an affordable package.
That combination of high style and low cost, said Ms. Pennington, âsays something about the future of design.â
