Imagine escaping to a place where architecture and nature become one, where you wake up surrounded by forest and sky without ever leaving the comfort of your bed. Nestled in a serene Norwegian nature reserve, WonderInn’s
mirrored glass cabin, also known as the WonderInn Delta, is a hidden gem that almost disappears into its wilderness setting. This is the first mirror cabin in Norway, and it has quickly become one of the most wish-listed getaway spots on Airbnb for good reason. In this retreat just outside Oslo, our design invites you to immerse yourself in nature’s beauty while enjoying luxury and comfort in equal measure.

Architecture that mirrors nature’s beauty

Our WonderInn Delta mirror cabin’s design reflects the world around it. Glazed in floor-to-ceiling mirrored glass, the cabin blends seamlessly into the surrounding landscape, echoing the colors and light of each season. From certain angles the structure nearly vanishes, creating the impression of a cabin hidden among the trees. This “invisible” approach is intentional: every detail welcomes the outdoors in rather than dominating the scenery. Even on winter’s darkest days, the expansive windows pull in precious light, illuminating a warm timber interior.

Step inside and you’ll discover a spectacular 180° panorama of the Øyeren delta and the forest canopy. Thanks to one-way mirrored glass, you remain invisible to the outside world. Wildlife and hikers see only the reflection of the woods, not the life inside. The balance of openness and privacy redefines what it means to stay in a cabin. As we like to say, it is not just accommodation; it is a retreat where comfort and the outdoors coexist.


Sustainable luxury in harmony with nature

At WonderInn, experiencing nature should be gentle on the environment. The WonderInn Delta is a study in sustainable luxury. Its small footprint—about 20 square meters—creates a discreet, comfortable setting where the delta remains the main character. By reflecting the environment, the cabin keeps the landscape visually undisturbed.

Practical features support a lighter impact: an off-grid toilet and smart water solutions reduce waste, natural wood interiors create a healthy indoor atmosphere, and efficient insulation keeps the space comfortable year-round. The goal is simple: comfort and sustainability can coexist, so you can enjoy nature without compromise.

Immersed in comfort amidst wilderness

Step into a Scandi-chic haven that feels both refined and cozy. A well-equipped kitchenette makes morning coffee or a simple dinner effortless, and an intimate dining nook overlooks the water. The bathroom-with-a-view features a rain shower. Heated floors keep nights warm, while soft textiles and light wood finishes frame the view like living art.

The main sleeping area places a plush bed beside the glass, so you fall asleep to moonlit treetops and wake to sunrise through the forest. Thoughtful touches—from an espresso setup to robes for the hot tub—make every moment memorable. Traveling with friends or family? A nearby cozy annex cabin adds space for two more guests without losing the intimate feel.


Serenity, privacy, and romance redefined

Although only about 25 minutes from Oslo, the WonderInn Delta feels worlds away. The cabin sits in an unspoiled nature reserve—no traffic, no noise, just wind in the trees and the gentle sounds of water. Privacy is complete. Even the bathroom’s floor-to-ceiling glass preserves seclusion, so you can enjoy the view without being seen.

The setting is ideal for romantic escapes and special celebrations. Many guests choose the mirror cabin for anniversaries, honeymoons, or proposals, often with small celebratory touches arranged in advance. Evenings bring starlit skies, quiet fires, and time that feels unhurried. It is a place where stress fades and connection returns.

Immersed in nature’s splendor

Staying at the WonderInn Delta means truly living within nature. Perched by the Nordre Øyeren reserve, the area is rich in wildlife. Watch for deer and foxes, or bring binoculars for the many bird species that frequent the wetlands and woods. Dawn often arrives with mist over the water and a chorus of birdsong.

If you want activity, outdoor options abound. Paddle calm channels by canoe or kayak, try your luck fishing on Øyeren, or follow scenic hiking and biking trails through forest and along the shoreline. Autumn offers foraging; winter brings quiet snow days enjoyed from inside or on snowshoes. Lillestrøm is close by for dining, though most guests choose to linger here.

Experience the magic for yourself

The WonderInn Delta is more than a place to stay; it is an experience that lingers. Our mission is to create small architectural gems that invite people into nature, without giving up comfort. Expect sunsets that color the sky, soft morning light through the trees, and nights wrapped in stillness.

If you are seeking a unique nature escape, a romantic hideaway, or an inspiring architectural stay, the WonderInn Delta is ready to welcome you. Book your stay and discover how mirrored architecture can make you feel part of the landscape while enjoying the ease of a boutique retreat.
