A Penthouse is the name given to the apartments or the units on the highest floor of a residential block or hotel. They can occupy one or more levels and are typically differentiated from apartments or duplexes because they have luxury features or occupy a more spacious floor space than their counterparts in the same building. Some penthouses have particular features like a private lift, 24hr concierge or a roof terrace with views across the city they are located in. Being located on the top floor of the buildings they occupy they offer more privacy and less disturbance for their residents. Of course, with these added features they are command a higher price and are harder to find especially in popular locations. The majority of penthouses in Qatar are found in The Pearl and some in Lusail in the new and luxurious Waterfront area developments.
Umm Salal sometimes spelled Umm Slal, is a municipality in Qatar. The word Umm, in Arabic means mother, while salal refers to large rocks or stones. The area has been given the name "mother of rocks" due to the large rocky formations found in the area. The municipality shares its borders with Al Rayyan to the south, Doha to the Southeast, Al Daayen to the east, Al Khor to the north and Al Shahaniya to the west. The municipality is the only one in Qatar that does not have any coastline.
The northern part of Umm Salal is largely occupied by agricultural land due to the presence of a large aquifer. In the 2015 census, Umm Salal accounted for just over 10% of Qatar's agriculture despite having only a corresponding 3% land size.
The southern part of Umm Salal is home to a town called Umm Salal Mohammed which has numerous farms, wells and a large water reservoir which is filled during the rainy season. The three main industries found in Umm Salal are construction, agriculture and retail. The municipality boasts the largest Mall in Qatar called Doha Festival City or DFC for short. The gigantic mall covers a staggering 244,000m2 and cost just under 6.5 billion Qatari Riyals to build. Umm Salal has in recent years gained popularity as an upcoming area to rent a home in Qatar outside of the capital with access to all the modern conveniences and variations of housing to suit all types of renters.
