1/4 FOR SUSTAINABLE COMMUNITY DEVELOPMENT SIBBESBORG COMPETITION OVERALL PLAN 1:15000 Principles of the design and the path to realisation History reborn. The proposal is constructed on the history of the area. The four manors and the historical fortress hill of Sibbesborg along with the geography create the backbone of the urban structure as they have done for centuries. The primary focal point for the spatial design is the Sibbesborg hill, which has been elevated to its former glory as an island at the river delta. Located at the area are the administrational functions of the community as was the primary function of the hill at the beginning of its inhabitation. Furthermore on the central island there is a del for the citizens for gatherings, leisure and commerce. As in the past, the people can find security and peace at the Hill. The water area around the hill is an extension of the Sipoonlahti fjord and the core of the urban structure. The main block at the southern tip of the island of the Hill is elevated on top of pillars thus leaving a straight visual connection from the Hill towards the fjord over the gardens of the main block. Each of the four manors have a different role at the design. manor stands on the high ground at the northern end of the town and can be seen from several locations in the townscape. It is also the cultural centre of the community. manor is a part of the central park area with a small boats marina. manor has the closest contact to the virgin rural landscape on the northwest part of the area (an ecological corridor towards the Sipoonkorpi forest and other woodlands) while manor and its vicinity create a marina for larger vessels. As an urban version of the historical structure the proposal is self sufficient yet well connected to the regional arteries. The city can function as a solitary unit. From the E18 highway opens a view to the city bay and its marina as well as to the Hill and manor. The main routes to the urban structure are from the two exits to the east and the west of the core. The main body of the highway is covered thus allowing the urban structure to advance naturally along the cliffs of the fjord towards south. A large portion of the competition area is proposed to be left as a green belt around the new compact city with connections to the surrounding woodlands and villages. The city structure is pierced with green arteries (both built park and natural greeneries) as well as contacts to the shoreline and coastal zone. The hydroponic vertical farmtowers provide the community with food as well as energy (topside windcraft). Aeroponic growing techniques in the towers more than meet the communitys needs thus providing surplus and giving economical boost to the city. The hydroponic farms continue both the heritage of Ingman foodprocessing and A.I. work on the area. All four hydroponic farmtowers are located at the mouth of the Sipoonlahti fjord. The shoreline of the fjord has a network of recreational functions such as a beach both at the seashore as well as at the centre of the city. Boulevards along the Sibbesborg hill water basin in the east and the west form a built contrast to the hill turned park as well as the esplanade at the southern edge of the hill. Along the banks of the water basin are located the main cultural buildings of the city forming a cultural centre. The southernmost tip of the middle island has a cluster of religious services and buildings and a wide parade towards woodland cemeteries. Local services (such as commerce, elementary schools, kindergarten and remote work centres) are located at the cliffs of the fjord. These local centres improve the network of services. Process The urban structure is created in layers as in the annual growth of a tree. There are four main phases in the implementation of the proposal. The design enables a fifth phase at the edges of the city. The basic unit for the design is the traditional closed city block, which is varied in height and block density through the whole of the proposal. The goal is to create urban spaces with minimum use of the competition land area. The densest structure is naturally located at the core of the city at the base of the fjord while the housing varies from the town houses to high risers. Using different block typologies a compact city centre is created around the historical hill. Variation in the block use (commerce and living combined) secures a centre with life 24/7.
SIBBESBORG COMPETITION FOR SUSTAINABLE COMMUNITY DEVELOPMENT 2 / 4 Methods of organising transport The centre of the town has two hub points: hub west and hub east. Both are connected to the regional subterranean rail connection from Helsinki towards Porvoo. The city design is flexible, it functions just as well with underground/metro system as with regional train connection. The western point functions as the gateway to the commercial and administrational centre while the eastern point is the portal to the educational and recreational centre. Also, the eastern hub is the southern end-of-the-line station for the Nikkilä-Sibbesborg pendulum fast light rail connection. Both hubs give access to the housing areas. The eastern hub houses the hospital of the city. The transportation inside the community is arranged with fast light rail circle lines of different lengths supported by compact city bus connections. All circle lines are connected to the hubs thus offering the best possible coverage for the internal as well as the external transportation. There are new bridges near the mouth of the Sipoonlahti fjord and at the centre as a part of the urban structure. Furthermore there are two gondola connections over the fjord. The city centre is formed to suit for pedestrians. The larger blocks are divided into smaller units with pedestrian and cyclist routes. The light rail stops are located in such fashion that the longest distance from any given point is no more than approximately 300 meters. The typology of the design of the urban structure is flexible and gives numerous different possibilities for the route solutions of the circle lines. The main road to the core of Sibbesborg is the Uusi Porvoontie which is rerouted further north of its current location and reformed to an urban city street. The new route is connected to both hubs. There are two exits from the E18 highway to the Uusi Porvoontie road. The third existing one (the middle one) is omitted. This enables the solution to continue urban structure on landscape bridges over the highway further to the south. The view from the E18 bridge over the Sipoonlahti fjord opens towards the centre, Söderkulla manor, beach, marina and to the south at the bay towards the sea. The parking of personal vehicles is located at the bedrock of the city and at the basements of the buildings. Also, some street parking is possible but not in larger quantities. A small boats harbour for archipelago lines is located both at the central marina at the core of the city as well as at the southern marina at the Eriksnäs manor area. Environment and landscape The principle of the design is to minimize the need to use virgin terrain for constructions. The majority of the competition area is still rural structure and woodlands as it has been for centuries. The major landscape alterations are basically returning the historical shorelines and forming low islands to bridge the urban structure between the shores of Sipoonlahti. The three islands have different roles. The historical hill is the centre of administration, services, commerce and meetings. The central island is an extension of the housing and has a religious centre at the southern tip. The southernmost island is for recreational use with beaches. All the islands are located in the Sipoonlahti basin north of the bridge of the E18 highway. The solution to focus the urban structure around the Sipoonlahti fjord leaves major ecological connections between Östersundom and Sibbesborg in the west and between Kilpilahti harbour and Sibbesborg in the east. The design forms green lungs to the both sides of the city. Ecological connections from the sea towards north and towards the woodlands of Sipoonkorpi are secured. The river mouth to the Sipoonlahti fjord forms a passage for the salmons to climb up the river. The riverformation follows a natural path in the city water basin.

SIBBESBORG COMPETITION FOR SUSTAINABLE COMMUNITY DEVELOPMENT 3 / 4 Ways of living and life-styles The design of the competition area is a combination of a high density urban structure (connected to the existing small housing areas of Eriksnäs and Söderkulla) and virgin rural areas and ecological connections. The design offers a possibility to live a true city life at the heart of the nature, a solution offering a true transaction between nature and urban structure. The purpose of the design is to emphasise the citta slow attitude of living and the connection to the sea and surrounding forests. The blocks can be constructed as a group effort of different people. Small housing areas (town houses) offer accommodation for approximately 3400 inhabitants. Blocks of flats are offered at medium height varying between III to V storeys providing housing for approximately 56300 people. Also, the top storeys (IV to XX) of the commercial blocks provide accommodation for approximately 14300 inhabitants for the total capacity of 74000 inhabitants and 34000 jobs. At the centre esplanade are located the high risers of the city at X to XX storeys. The grid offers a variety of possibilities in the arrangement of services and commerce. Sustainable traffic solutions leave the shorelines free and make it possible to create an efficient yet pleasant milieu for the inhabitants and visitors alike. - town houses: lot area 255.000 sqm (e=0,6) approx. II storeys, 153.000 sqm, 3400 inhabitants - low block of flats: lot area 815.000 sqm (e=2,0) approx. III storeys, 1.630.000 sqm, 36200 inhabitants - medium height block of flats: lot area 301.000 sqm (e=3,0) approx. V storeys, 903.000 sqm, 20100 inhabitants - commercial, administration, services: lot area 321.000 sqm (e=5,0) I-III floors, approx. 963.000 sqm, 34000 jobs, top floors (variation IV to XX), approx. 642.000 sqm, 14300 inhabitants The eastern part of centre has a large recreational area with sports arenas (swimming, hockey, running courses and such). The eastern hub feeds the regional as well as internal traffic flows to this area. Also, the southernmost island in the fjord has a beach. The larger greeneries have allotment gardens for the inhabitants and the nearby forests offer a possibility to take advantage of the offerings of the nature. The solution is an independent town in interaction between the new town of Östersundom and the second oldest town of Finland, Porvoo. Methods of organising employment and services Around the hubs west and east are located the heart of the services and commerce. The local piazzas provide a classical method of distributing goods around the city, so each inhabitant has a possibility to same goods as the ones nearer the centre. The services for the management of water vessels is a traditional service of Sipoo. South of E18 highway are located tunnel canals inside the rock walls of the fjord. The canals lead to the underground docks area where boats can be handled, serviced and prepared for storage. The storage facility has a lift which can move boats to a honeycomb of shelves for winter storage. The service is vital for the seafaring people of Sipoo and the scale of the operation and the honeycomb storage facility enables a substantial new labour possibility. The job possibilities on the surface include a network of workstation facilities. They facilitate a possibility of cross organisational workgroups whereas the headquarters may lie where ever in the world. The arrangement minimizes the need of transportation both inside the city as well as outside of it. At the core of the city at the island of the Hill is located a commercial centre with high risers of approx. XX storeys. There are hotels, shops and services under one roof, easily accessible. There are also flats at the top floors. Against the complex is the Piazza del Popolo and the administrational centre of the city.

4/4 FOR SUSTAINABLE COMMUNITY DEVELOPMENT SIBBESBORG COMPETITION Forms of eco- and energy efficiency The community is self sufficient. The energy is produced from the windcrafts located at the hydroponic farmtowers at the mouth of the Sipoonlahti fjord, geothermal wells around the city and solar panels above the highway tunnel. The structure of the city can be evolved in layers as with trees annual growth. The need of traffic is minimized. The city of Sibbesborg is self sufficient and the local service centres provide the basic services. The solar panels function also as barriers against noise from the highway. The cables are located at the northern part of the roof constructions of the highway tunnel. The year round hydroponic farmtowers provide each a production yield of sustenance for inhabitants block (approximately 60 m x 60 m). As with the rest of the town, the towers can be constructed in phases. The larger greeneries of the city also have allotment gardens for the citizens.
