Continuation War, the population of Espoo grew by four thousand as frontline soldiers and evacuees from ceded territories (including the Porkkalanniemi peninsula, leased to the Soviet Union between 1944 and 1956) were settled in the city. Espoo's location right next to the capital city of Helsinki attracted people working in the capital city to move into the rapidly growing neighbour city, and already before World War II there were many suburbs along the Rantarata railway, such as Leppävaara, Kilo and Kauklahti which had formed into an industrial area. After the new Jorvaksentie road (predecessor to the Länsiväylä highway) was completed, new detached houses were built along it, particularly in Westend. After the war, many detached houses for soldiers having fought at the frontline were built in Espoo. The highest increase in population only started in the early 1950s when the Asuntosäätiö foundation started construction of the garden city of Tapiola, and construction of a new campus area of the Helsinki University of Technology started in the neighbouring district of Otaniemi. In the 1940s and 1950s Espoo grew more rapidly than it could afford. The infrastructure of Espoo was not prepared to handle such rapid growth. There was no time for proper zoning, instead new houses were built as people bought lots in the city. A major change happened in the late 1940s as the Helsinki University of Technology moved from Hietalahti in Helsinki to larger premises in Otaniemi, and the planning of the Tapiola garden city district was started. As the city did not have enough money to fund the construction of the student village in Otaniemi, the technical university students took to the matter to their own hands, both by gathering money through various activities and taking part in the actual construction. About 800 thousand bricks from the Embassy of the Soviet Union in Helsinki, which had been destroyed in the bombing of Helsinki, were used to build student apartments in Otaniemi. From 1944 to 1956 the Espoonlahti bay between Espoo and Kirkkonummi served as the border of the Porkkala Naval Base under the control of the Soviet Union. A large part of Kirkkonummi, as well as a narrow strip of the sea and a couple of islands in Espoo were included in the area of the naval base. In Espoo, the Kauklahti railway station near the border to the naval base became a tightly controlled border station between
