Design instructions


Starting point:

Power Plant app. 35tm2 + the personnel service building 5tm2 + Machine Works building app. 15tm2

Tot. app. 55tm2


Buildings doomed to be demolished / dismantled:

- Machine Works (Konepaja); made completely of prefab elements, app. 15tm2

- Transformer Halls  (B) app. 3tm2

- Sulphur Extraction Facility (M) app. 1000m2

- Wet waste storage (N) app. 200m2

- Suphur Processing (O) app. 500m2

tot. app. 20tm2

remains app. 35tm2, part of which can be demolished/dismantled



Possibly preserved parts - a plan drawing

Approximate target:

It is important to understand that your design in the end must be app. 30-40tm2 and include include ⅓ interior refurbishment, ⅓ new floor construction within existing buildings, and ⅓ totally new building parts, thus app.:

  • reused existing spaces 10tm2
  • new floors within existing building envelopes 5tm2 
  • new construction at lest partially made of recycled building and moved parts from the site 5tm2 
  • purely new construction 20m2


Cutting concrete with diamond saws and wires have become commonplace technique. Please see for example this informative video:

Outdoor areas: These need to be designed to the site

  • Outdoor terminal for Vantaa buses
  • Skateboarding park
  • Spaces for Flow Festival
