The facade of any structure is the first line of defence against any weather condition – be it the summer sun, intense rain, extreme cold, or the daily temperature fluctuations. These circumstances have the potential to cause expansion, contraction, and eventually cause cracks over time. Architects, builders, and property owners must ensure the longevity of their projects while preserving their aesthetic appeal.
Monsoons in India vary from gentle coastal showers to the turbulent gusts in city areas. The primary concerns during the monsoon are water ingress and material degradation. Even the smallest gap can become a point of water penetration during heavy rainfall. Humidity and constant moisture can cause finishes to peel, wood to warp, and metal to corrode. Moreover, considering the wind load is also essential in design. Especially in high-rise buildings, façades must resist wind-driven rain and strong gusts that can threaten structural components. It is this layered understanding of threats that defines Dhawan’s strategic responses.
The next crucial step is the selection of materials in design. One of the materials used is textured concrete and stone cladding, as they are naturally resistant to monsoons. These materials develop character over time and resist seepage when detailed correctly. Another material is metal panels, such as aluminium and zinc, which are powder-coated appropriately, making them corrosion-resistant and thermally efficient. For a traditional look, we also use ceramic and terracotta tiles, as they are earthy and breathable. These tiles are used to create rainscreens in designs. Double-glazed glass have hydrophobic coatings and prevent corrosion.
My design philosophy is rooted in empathy, foresight, and integrity. You cannot stop the rain. But with the right façade, you can welcome it without fear. This, I believe, is the hallmark of thoughtful architecture.

In monsoon-ready facades, it is essential to have proper details to avoid water ingress. Our designs often have slope-driven geometry with proper projections and overhangs to direct rainwater away from the structure. Drip edges and flashings with stainless steel are incorporated along window sills and parapets to guide runoff. Moreover, behind all facades lies a hidden waterproof membrane—often bituminous or polymer-based, which serves as a final line of defence.
Facades must resist moisture and enable natural ventilation. Jaalis and perforated panels can be used to filter rain while allowing cross-ventilation. Operable louvres and shutters also enable flexibility; open during dry spells, closed during storms. By combining smart material usage with architectural wisdom, we create façades that are both impermeable and dynamic, allowing users to connect with the environment, not isolate from it.
