In early May, we kicked off a planned renovation and expansion of our main building here on Marholmen. The main reason we decided to do this was, first, that our existing kitchen was simply worn out and not designed to handle the large number of guests we welcome here on the island every year. Additionally, our ventilation system needed to be replaced with a more modern and sustainable version. And while we were at it, we took the opportunity to make a whole host of other improvements to further enhance the experience for you as our guest.
Construction took place in two phases:
Stage 1 – Done. Restaurant Hermans is open every day ✅
Phase 2 – Complete. Our new lobby area is now ready ✅
Phase 3 – Complete. The new Marholmen opened on July 31 ✅
Construction took place in phases
Marholmen's new spa has now opened.
During the renovation, we built upon Marholmen’s interior design philosophy, which is based on the four elements of nature. Earth, fire, air, and water are also incorporated into the spa, creating a holistic experience of weight, warmth, flow, and stillness.
In addition to renovating to improve the flow for our spa guests, the biggest news is that we are building a new infinity pool overlooking the water on what is currently the spa terrace.
The steam room, dry sauna, light therapy room, treatment rooms, and small hot tub will remain, and will be complemented by new spa experiences such as foot baths and infrared chairs.

Developing Marholmen our vision—to become Sweden’s best archipelago destination—year-round is both an incredibly enjoyable and incredibly challenging task for all of us who work here at Marholmen. We’ve set a very ambitious plan extending through 2027 for how we’ll get there, and now we’ve completed the biggest and most challenging step—renovating and expanding the main building.
