Alvand Tower – Hariri & Hariri

Alvand Tower

This office tower is located in the dense urban fabric in the center of Tehran. A simple rectilinear plan covers the whole site in a mid block with existing structures on two sides and an alleyway with access to a building in the back
What makes this 12 story office tower iconic, is its double skin exterior. The inner skin is mostly glass. The outer skin is a shading device made of composite aluminum panels fabricated with the aid of laser cutting and bending technology over a steel structure. The pattern chosen for this outer façade is inspired by cosmic symbol and motif of a mandala. This symbol is derived from the Persian belief that intersection between circle and a square is the geometric manifestation of paradise. This geometry is abstracted, repeated and folded on two sides of the outer facade. The outer skin acts as a brisoleil, shielding the interiors from direct sun providing a healthy and sustainable working environment
The two skins are approximately two and a half feet apart. With the aid of LED backlighting in this cavity, the whole structure glows at nights like a beacon of light. The geometric openings in the outer façade turn from negative into positive silhouettes, reminiscing Persian blue mosaic work on earlier structures and domes.
The Alvand Tower presents a balance between cultural identity and essential need for modernity. A dialogue between & interior and exterior, public & private, old & new are all debated and explored in this structure
The circulation core occupies the north side of the building and is faced with stone tiles with small openings marking the entrance to the building. At the ground level the space is divided into a retail space and a small entrance lobby with ceiling articulation inspired by Persian squinches (intersection between circle & square) continuing the concept in to the inside
