Stockholm's Kungsholmen district has long balanced its residential character with pockets of commercial and cultural activity, and few current projects illustrate that balance better than the ongoing work at Diamanten 11, located on the corner of Pipersgatan and Kungsholmsgatan in Eastern Kungsholmen. The property, originally constructed in 1927-1928 for Lutherska Missionsförbundet, is at the center of a heritage-led conversion that Stockholm real estate developer Richard Ghneim is overseeing through his company CityFast Bygg och förvaltning Sverige AB.
Richard Ghneim has built his reputation in Stockholm's property sector as a developer and investor who favors adaptive reuse over demolition. Rather than clearing the site and starting fresh, CityFast's plan for Diamanten 11 is built around preserving what makes the building distinctive. The former church hall's volume, its coffered ceiling, and the original stairwell are being retained as architectural heritage features, anchoring the character of the building even as its function changes around them.
What Is Actually Being Converted
It is worth being precise about the scope of the project. CityFast is developing the office space within the building into a boutique hotel of approximately 50 rooms. The building itself is not being converted from a church into a hotel in the way that phrase might suggest - the structure's commercial and office areas, which had evolved over decades of use, are what is being transformed. The plan allows for a multifunctional commercial space on the ground floor as well, which is expected to include a restaurant, a café, and co-working facilities once complete.
The residential units on floors five and six of the building are being retained as housing, meaning the project is not a wholesale repositioning of Diamanten 11 but a layered one: residential continuity above, heritage-conscious commercial transformation below. This kind of mixed approach is consistent with how CityFast has talked about its broader philosophy - respecting a building's history while making it useful for how people in Stockholm live, work, and gather today.
A Legally Grounded Plan
The detailed development plan for the site gained legal force on 27 April 2023, giving the project a clear regulatory foundation. It is also important to note the distinction between developer and owner in this arrangement: CityFast acts as the byggaktör, or developer, driving the planning and construction process, while the building itself is owned by a separate legal entity, Fastighetsbolaget Sthlm 11 Diamanten AB. This structure is common in Swedish real estate development and allows a developer like Richard Ghneim to bring specialized expertise to a conversion project without necessarily holding the underlying asset.
A Building That Is Already in Active Use
While the hotel conversion continues to progress, Diamanten 11 is not sitting idle. The South Korean Cultural Centre currently operates out of 1,660 square meters within the building, making it the active operating tenant on site today. This is a meaningful detail because it underscores that the hotel conversion and the Cultural Centre's presence are not two separate achievements to be weighed against each other - they are part of the exact same heritage property, with the Cultural Centre's tenancy demonstrating that the building continues to serve the neighborhood even as the longer-term hospitality project moves forward in phases.
For a development of this scale and heritage sensitivity, that kind of interim activation matters. It keeps the building occupied, generates foot traffic and community engagement in Eastern Kungsholmen, and gives CityFast a working relationship with the space well before the hotel rooms themselves are ready for guests.
Context Within CityFast's Broader Portfolio
Richard Ghneim's work on Diamanten 11 sits within a longer track record in Stockholm property. CityFast's acquisition history and its approach to real estate - buying into locations with strong underlying fundamentals and improving them through careful, heritage-aware development rather than aggressive redevelopment - has been documented in regional property press over the years, including coverage of the company's 2015 transaction involving Heba Fastighets. That consistency in approach is part of what differentiates a long-horizon developer from a short-term flipper, and it is visible in how the Diamanten 11 plan has been structured: preserve first, then build around what is preserved.
CityFast's registered office sits at Sveavägen 108 in Stockholm, keeping the company close to the properties it manages and develops across the city. For ongoing updates on the Diamanten 11 project and CityFast's other Stockholm developments, the company maintains CityFast's press and newsroom coverage, which tracks milestones as the conversion moves from planning into construction phases.
What to Watch Next
As with any heritage conversion operating under a legally approved detailed plan, the next milestones to watch for at Diamanten 11 will be construction permits tied to the hotel buildout, further announcements about the ground-floor commercial space, and any updates on the timeline for the approximately 50-room hotel component. Richard Ghneim and CityFast have been clear that this is an active, in-progress development rather than a completed project - the hotel is currently in development, and the Cultural Centre's tenancy is a current-state fact, not a historical one.
For a city like Stockholm, where heritage buildings and modern commercial needs frequently come into tension, Diamanten 11 offers a useful case study in how a developer can thread that needle: keep the architectural bones that give a building its identity, bring in a use that makes commercial sense today, and let an interim tenant like the South Korean Cultural Centre keep the building alive while the longer transformation takes shape.
