Spacious and open detached houses in the desirable area of Marjaniemi

A development containing five detached houses, As Oy Helsingin Merisara, is set to be built in the fantastic and desirable coastal area of Marjaniemi. The single and two-storey homes will be built on a characterfully sloped plot in the verdant residential area. They will look captivating with their extensive square footage, open floor plans and large windows that open out towards fantastic nature views. The large windows and pleasant terraces will bring even more delightful space and airiness to the living spaces.

The Merisara homes can be adapted to a wide range of needs and life situations. The sauna, utility room, wardrobe and good-sized heated or semi-heated storage all provide everyday luxury. It is possible to order a cooling/heating air pump, atmospheric fireplace, and terrace glazing as additional work.

Each home comes with two parking spaces, one of which is a carport space in the immediate vicinity of the entrance, while the other is an uncovered parking space either next to the carport or near to the plot entrance road. The single-storey homes have a stylish atrium and a small garden at the entrance.  The two-storey homes’ large, partially covered terraces on top of the carports offer a great place to relax and enjoy the beautiful surrounding nature. The single-storey homes have solar panels on the roofs of the carport and outdoor storage.


As Oy Helsingin Merisara was designed by SAFA architect Janne Jylkäs. The detached homes combine modern streamlining and soft wood tones to fit in well with the area’s detached, semi-detached and terraced properties. The harmonious colour scheme of the homes’ facades features dark and light wood tones with warm accents to create a stylish appearance on the impressive sloped plot. The concrete wall surfaces meanwhile add just the right touch of edge and character to the buildings.

I’m particularly pleased with the functional floor plans of the homes, which really bring the living space to the fore. Slightly higher ceilings and large windows with views of the beautiful environment in several directions all add to the pleasant feel. The adaptable spaces provide plenty of possibilities to meet the needs of various occupants. There is enough space for a home office or, for example, a more relaxed living room.

The location in the desirable area of Marjaniemi made this site very interesting to design, in a positive way. The surrounding building stock is varied and provided good opportunities to implement a stylish development. The buildings’ colour scheme and sloped roofs give them a sense of sophistication.

Asunto Oy Helsingin Merisara is just a few hundred metres away from the shore in maritime Marjaniemi. Originally founded as a summer villa area in the early 20th century, Marjaniemi is still a characterful and green residential area mostly populated by single-family houses. Its exceptionally beautiful and scenic landscapes have also been captured in several Suomi-Filmi movies. Nowadays the desirable area is known for its gorgeous green space and proximity to the sea, plus its distinguished and primarily two-storey buildings.

The majority of its residents are families with children. Although the area is quiet, a wide range of everyday services are available nearby, and there are also transport connections to places further afield. There are plenty of coastal and other recreational activities in the area. There are lots of parks, playparks and swimming beaches, with a music institute and art school just a kilometre or so away. And in Oscarinpuisto park, right next to Merisara, you can play tennis in the summer. The enchanting Marjaniemi allotment garden is around a kilometre from Merisara. There are also plenty of club and association activities for all interests. There are several boating and sailing clubs in the area, plus a swimming club and one of Finland’s biggest rowing clubs.
