Exterior design is a first positive impression for the money you spent in construction.The Plots in Bangalore are very expensive, and gated communities with smaller plots like 30 x 40 are usually available throughout the Metro.
The Biggest error can be, just leaving the design part to the contractor.Its just like penny wise decision.
The recent design we have done in Jalahalli is a very small plot, yet, we could be able to achieve a pure contemporary design, that, keeps the owner proud.
