The final solution - The Master Plan

Integrated Planning

Partial areas with 1000 flats divided on 10 developers. Meetings monthly with

planners for water, energy, transport and waste.

Some facts in short for the project

•size 160 ha + 40 ha lake (90 ha residential 30 ha public)

• 11.800 new flats (45% rented), 40 – 120kvm

• 290.000 m2 new offices, schools, shops, services

• 25.000 inhabitants and 10.000 jobs

• huge infrastructure projects – railway, tunnels, district heating, broadband

• investments 3 billions Euros, the cities part 15%

• construction time 1995-2017. Today 70% finished

Facts on Housing•Most sites owned by the city and leased

•Density (e) 1.43 incl public space (2.2-3.0 excl)

•Heights of buildings – average 18 m (12-24 m)

•46% rented apartments 54% owned in associations

•Apartment sizes from 40 sqm to 120 sqm – average 75 sqm (two bedrooms).

•75 sqm: Rent 1400 €/m Price 350,000 € + 300 €/m fea

General goal for the project

The environment by emissions shall be 50 % lower than new housing areas from the early 1990s. Result today: about 30-40%

Green planning

25 sqm free space per apartment •All green space in connection through the area – green corridors

•1.000 new trees and all lawns are new

•Always into consideration of existing landscape

Every block has its individualy designed garden

Green pathsall along

Water treatment

•Storm water from the blocks is collected and let out into the lake locally

•Storm water from roads is treated in baisins locally

•Water from households treated in the waste water plant - sludge to biogas and fertilizer

A channel for Stormwater reflecting the sky

Green roof collecting rain

Waste •Waste separation – organic, combustable, newspaper from inlets in each courtyard

•Metal, glass, packages and hazardous in waste-rooms inside every house

•No landfill from waste – all recycled

•Waste vacuum system to reduce traffic and labour

Inlets for the 3 largest fractions of waste

Vacuum waste system reduses waste transports 80%

Pipes for waste transports under the ground

Energy

•Combustible waste to district heating and electricity – combined heat and power

•Biogas from waste water – to busses and cookers

•Heat from treated wastewater into district heating and cooling

•Solar cells, solar panels and fuel cell

•50% of energy need out of local sources

District Heat in Stockholm

Heat production 9 TWh

District cooling 0.4 TWh

Electricity 1,6 TWh
