The first thing you notice isn't the view. It's the quiet. Standing on the smooth coastal rocks of Stråholmen, the only sounds are the soft pull of water against stone, the occasional creak of a wooden jetty, and somewhere far off, a gull riding the wind above the Oslofjord. Then you turn west and the sea opens up in front of you — a wide, glittering expanse that catches the afternoon light and holds it long into the evening. This is what it feels like to own a private island in the Sandefjord archipelago.
Stråholmen is not a figure of speech. It is an actual island — a 9,429-square-meter freehold plot just 110 meters off the mainland coast of Vesterøya, connected to the world by a short row across calm water or a quick trip in a motorboat from the dock. The island has its own sandy beaches, its own smooth sunbathing rocks, its own jetty. On a clear July afternoon, with children jumping off the dock and mackerel on the grill, it is the kind of place that resets something deep in you.
The existing cabin dates to 1929 and still carries the honest simplicity of that era. Tongue-and-groove timber walls, low ceilings, windows that frame the sea like paintings. It hasn't been dramatically altered — there were some updates in the 1980s — and at 43 square meters of interior living space it is compact, but it works as a summer base while the bigger story unfolds. Because the bigger story here is what comes next.
In June 2024, the property received a framework permit for the complete redevelopment of the site. The permit, valid for three years from approval, covers the demolition of the current cabin and the construction of a new main cabin and a separate annex, both designed by Lund Hagem Architects — one of Norway's most respected architectural practices, known for their sensitive, site-specific approach to coastal and mountain buildings. The planned main cabin includes an open-plan kitchen and living area, one bedroom, and a west-facing terrace angled precisely for sunset watching. The annex adds two more bedrooms, a shower, and a WC. Altogether, the new development would give you a private island compound designed at a level that almost never appears on the open market at this price point.
Public water and sewage lines were brought to the island in 2025. Not yet connected to the property, but the infrastructure is there — which matters enormously. Electricity is already installed. The groundwork, literally and bureaucratically, has been laid. For an international buyer looking at Norwegian leisure property, these details save years of effort and navigating municipal processes you'd otherwise face from scratch.
The location deserves some context. Sandefjord sits on the western shore of the Oslofjord, roughly 120 kilometers south of Oslo. It was once the whaling capital of the world — the Whaling Museum on Storgata tells that story in vivid, sometimes brutal detail — and today it's a prosperous coastal town with a relaxed pace and serious maritime culture. The harbor fills with sailboats from May through September. The Mjølnerpiren waterfront has good restaurants, and the local fish market does fresh shrimp on Friday mornings that people drive significant distances for. Sandefjord Airport Torp, just 15 minutes away, runs direct routes to several European cities, which makes this accessible as a proper second home, not just a Norwegian-only retreat.
From Stråholmen specifically, you're a short boat ride from the public bathing spots at Langeby and Vøra when you want company, and a five-minute walk around your own coastline when you don't. The coastal path along Vesterøya is popular with cyclists and walkers, and Galleri Flood — a respected contemporary art gallery on the peninsula — hosts exhibitions through the summer months. The sailing routes through the outer archipelago are excellent, and the fishing around the skerries is the kind that locals talk about quietly and visitors discover with something approaching disbelief.
Winters here are mild by Norwegian standards. Snow is possible but not guaranteed. The island is quiet from October to April, which suits buyers who plan to use it seasonally — and the Norwegian leisure property market, particularly for island plots with development permits, holds value exceptionally well. For European buyers, the Norwegian property ownership framework is straightforward, with no restrictions on EU or EEA citizens purchasing recreational property. Non-EEA buyers should verify current regulations with a Norwegian property lawyer, but the process is well-established and widely understood.
The rental potential, should you choose to pursue it, is real. Architect-designed island cabins in the Oslofjord archipelago command strong weekly rates from June through August — comparable Norwegian properties with private jetties and sandy beaches regularly achieve rates that make seasonal ownership economics work in your favor.

Opportunities like this don't repeat. A private island plot in the Sandefjord archipelago with an active architectural permit from a named practice is not something that quietly reappears on the market a year later. If you've been looking for a base in Scandinavia — a place that gives your summers actual shape — this is it.
Get in touch through Homestra today to request the full architectural drawings, permit documentation, and to arrange a viewing. The island is best seen on a still morning, when the light comes in low across the water and you can walk the whole shoreline in twenty minutes and still not want to leave.
