Also known asflagdhwajajhanda
A plot or house squeezed between two tall buildings on opposite sides, even South and North, gets neither balanced magnetic and gravitational force nor sun rays. Such a house wrecks every effort and should not be bought even if it is offered free.

The South-West is ruled by Nairitya, with Rahu-Ketu as its planets and gomed (hessonite) as its stone. Balanced, uncut and right-angled, it gives prosperity, stability and skill, and it must be the highest part of the property in both ground level and building height, which is why a dhwaj (flag) is raised there.

The shadow of a temple's shikhar or dhwaj must never fall on a house during the second and third pahar, 9 am to 3 pm. It ruins the household, whatever the temple: Jain, Vaishnav, Ram, Brahma, Mahadev or Durga.

The outermost band of a plot, the pishach bhoomi, is the seat of the 32 lokpals and bears the noise of the road. It is where the boundary wall and its gate, servant quarters, guards and pets belong, where flags are hoisted and where shilanyas (foundation stone laying) is done.

You are losing, because the East (the sun) gives all the energy. Either build a second storey or put up a flag: a metal flag of brass in the South-West of your roof, higher than their building, so that your building starts receiving cosmic energy.
Use green colour and a flag-like pattern: put up a flag (dhwaj) in the North-West and, if possible, open the North-West with a window; this brings at least some balance. Swar vigyan can do still more without expense or demolition.

Balance it by fixing a dhwaj (flag) in the South-West.
