a speculative investigation

|

An era is soon to be over and the island seems to slumber, surface dilapidated, ominous structures dominating the landscape.

With the strategic position at the inlet of Stockholm, in between the city and the archipelago, the island has gone through different phases, changing the intensity of self-sufficiency and productivity.

This thesis is a speculative investigation on how to develop a resilient strategy, its about ecological recovery, resposibility, how to reinhabit and activate the iland in phases by gently making incisions and efficiently use the resource found on the iland. Reusing the structures left behind.

Taking on account the unsurtainly of the future, its about slow, and gentle changes over time.

CONTEXT INVENTORY

The oil era is soon over and the island seems to slumber with activity on the dilapidated surface.

But in the mountain they are pumping with activity.

Christoffer, the son and the co-owner of stora HĂśggarn, an energy system engineer, self learned rock blaster and the caretaker of the island. With a stubbornness driving his mentality to the extent of â&#x20AC;?we are trying to do everything ourself, not bringing in unnecessary services, so I learned how to blaster through the mountain myself.

As today he is the driving force in a research center for thermal heating and development using the chambers insinde the mountain.

Today they are testing out a new drilling technique to research for the crust of the earth for in principal an eternal energy source.

The crust usually lays between 2-7km. It could be reached within a decade or several.

When reached that means that the iland will be selfsufficient in energy in surplus, producing a huge amount of Stockholms demand. if not all.

The drill inside the camber is installed and they are blasting through the mountain on the east side to manage the rest-product of the process. A rearrangement of material.

PHASE 0 ECOLOGICAL RECOVERY & COLLECTIVE [RE]INHABITATION | In disscution with Arifin Sandhi at the Dept. of Ecology, Environment and Plant Sciences (DEEP), Stockholms Universitiet, Im proposing a site specific water cleaning system reusing the three cistern still in working condition from the 70´ on the hillside.

Cleaning the water with kråkmossa as a PhytoFilter, a natural process cleaning the water and sediment from heavy metals.

Kråkmossa is a moss from the mining areas up in the northern sweden. Especially good to extract heavy metals from water end sediment.

When the crust is reached the water will be tempered for longer growing seasons.

The process involves cleaning of the water, harvesting the organic matter, drying it and then burning it. The last step is to consecrate the ashes into bricks and store it in the mountain for future mining.

The energy demand will be served by vacuum solars placed on one of the first incisions on the skyline. The chimney to the burner. and the connection corridors.

As the walkways get prepared up to the cisterns on the industry hill and the water clening facility there will be spare-some cut-downs.

The walkways are raised in granite medium gravel in gabion boxes coverd with small size gravel (conceptual collage) , a biproduct from the thermal-heating research.

The cisterns on the promontory are being convented into collective living and wokspaces for the researchers of the and the caretaker of the iland.

The strategy in the incisions are conceptual informed by fragments of history and the existing context.

Traces of what the called The yellow villa are left on drawings and photos in the archive. The villa were mainly used as a summer residence for the owner of the iland and his wife in the 1700-1800. The west wing were housing a tavern and the other one a school later on.

DAYLIGHT STRATEGY | CUTOUTS

PRIVATE

Without puncturing the structure with panoramas the small cutouts for the daylight gain is gently positioned without undermining the structure, so it still structurally support itself without any massive reinforcement. (The cutouts are placed without interfering with the riveted and welded grid, the biggest ones are for connections on the two main levels.)

The sequence throughout the space are guided by daylight BARN/BUNKER/CICTERN LONG SECTION EAST (5) cutouts.

1:100 The main light source is by skylights in various sizes and positioned in strategic places.

The inside of the cistern will be polished from dark material according to the path of the sun to reflect as much light as possible to the ground floor.

Some of the small circular cutouts will be working as natural ventilation when needed. Sealed by flexibel sheets of transparent material that could be hoist automatically or manually. The other cutouts are covered by sheets of transparent material both inside and outside riveted on with a sealing material in-between.
