Polish houses are built solidly of materials like blocks to withstand cold winters and are heated and insulated. Common house types in Poland include one-family, country, terraced, semi-detached, modern, and traditional houses. Many people also live in blocks of flats that were built modernly or in the 1980s as well as in tenement houses. Houses in Tenerife typically have flat roofs, swimming pools, and terraces and are usually not heated due to the warmer climate, instead having gardens beside the homes.
