Renovating a house

Write about a construction or renovation project in Serbian, in full sentences - building a house, a weekend house, or renovating a room. Describe the materials used, who did the work, and how long it took. Try to use a deverbal noun (an -ање/-ење noun built from a verb, like реновирање) and a number in a case other than the nominative (for example when counting workers or years). You can write in either alphabet.
