One very good option is Multi Orchards Farmhouse Scheme located at an ideal distance from Islamabad. A distance at which people in the West prefer to live in the suburbs of a major city. At a safe yet convenient distance from the hustle, bustle and traffic of a major city. It is at a distance of about 27km from the entrance to Islamabad (New Airport Turning) and most of the drive to Islamabad is on the beautiful 6-lane M-1 Motorway.
In a very reasonable budget (of around Rs 70 lakhs) one can easily buy an ideally located 5-kanal plot of 22,500 sq ft area (about 2,090 sq meters).
With this sort of area, you can have a yard at the front of the house as well as at the back and the sides. In other words a truly detached property for a house with trees all around it. Plots of land twice that size are available for around 1 crore.
The scheme itself is of a well regarded real estate brand of Islamabad (Multi Professional Cooperative Housing Society - MPCHS), and is developed on very modern lines. Inside the scheme are numerous parks, markets and sports grounds. Also, a huge Golf Course and Community Club are in the works.
It is the only place one can have a house in a reasonable budget near Islamabad with open yards and trees on all sides of the house. You get a view of the mountains too. And it is a beautiful real estate development with wide roads, gated community, with 24-hour security personnel, CCTV cameras, internet etc.
In order to get there one needs to exit from the Brahma Bahatar Interchange if you are driving towards Peshawar on the M-1 Motorway. But if you are not in Islamabad, you can see photographs on this facebook community:
Other options around Islamabad are Gulberg Farmhouses but these are comparatively very expensive. Another one which is way too expensive is the farmhouse scheme near Faizabad on Murree Road. But beyond the reach of most people.
