Construction work in 2006

We needed an extra storage house near by the see on our summer place . This was because of the long distance to the cottage up on the hill. Walking up the 50m path to 13 meters of height had pointed out laborious, expecially in case you have to transport tools and heavy things up and down to the seaside when ever needed there. On rainy days the storage on the seaside is practical. Just to leave things there and wait better weather to cary them up. One good usage for a shelter on the seaside is of course when you go for swimming and want to change your clothes or to leave your bathing robe somewhere while swimming.

The building was designed to fit to the style of the cottage on the hill. Our court architect Kari Laine had designed the cottage and was asked with in drawing the storage house.

In Sipoo, nearby Helsinki, an exceptional permit was needed to buid at all and expecially when building near by the see. Including to this process we had to ask the literal permission from our kind neighbours and lot of documents and paper work was done.

After leaving the exceptional permit we had to wait some months for acceptance of the other inhabitants if there would had risen any objections against the permit.

The construction work was started in summer 2006.


Building engineer Ilkka Heinonen was choosen for the person responsible for the construction work. Ilkka made all the construction calculations and plans.

Kauko Koutaniemi from Raksane Ltd made the measurements for the construction positioning. Kauko was assisting Ilkka in construction plans by his long experience and expertise in building wooden houses

The position was marked by steady planks mounted on the ground. For digging the holes for pilars some thin strings were strained around the exact position of the building.
The ground was very hard dry clay. In the depth of about 150 cm there came a layer of sand where the digging was stopped. Against damage by frost the secure depth of the clay ground should have been down to 200 cm in the southern Finland. The sand layer was very wellcome for us. Digging was very difficult and slow through the rootstock of the surrounding trees and through the hard clay with stones.

Me Tarzan. After the holes were ready I built the moulds. Moulds for the base were made of plywood and strenghtened by surrounding planks. The styrox plates were mounted around for frost protection between the planks. A blue 10 cm uretan frost plate was buried under every pilar.
Here you may see the ironclad mould ready for the conceret. Light gravel was poured around the mould for a bit more shelter agaist freezing. The blue uretan plate is visible on the bottom.
Here the moulds are ready made. The casting was made next by a feeding casting method. The car with some cubic meters of concerete was brought to the island by a special ferry boat.
After casting the basement, the pilars were risen on the concrete base. Pilars were layed by Leka bricks. Inside every pilar there is a hole full of concrete and four 12 mm thick steel bars starting inside the base. I think the pilars are very steady.

This is the pilar on the south-east corner. Here you can see thin red crossing strings for positioning. Actually one string has been moved a bit to make room for working. Strings mark the height of the pilar as well.

Pilars are ready made. Before the winter we covered the construction area by 10 cm styrox plates against the cold. Over the styrox we layed a plastic sheeting plus a thin layer of clay and 20 to 40 cm layer of sand. This picture is still waiting for the sand.

In the year 2007 we started the actual building. Just follow this link to the next page.
