Sarv Office Building by Tamouz Architecture: A Layered Façade Redefining Light, Privacy, and Urban Interaction

The Sarv Office Building in Tehran, designed by Tamouz Architecture & Construction Group, presents a compelling architectural exploration of dualities—light and shade, openness and enclosure, visibility and privacy. Completed in 2018 and spanning 4,420 m², the project transforms a partially built structure with severe site constraints into a dynamic urban presence through a meticulously layered façade strategy.

Site Constraints and Conceptual Framework

When the design team was first briefed in June 2017, the building was already under partial construction, tightly occupying 100% of the plot area. With only the southern façade available for natural light and airflow, the architects faced a demanding challenge: how to create a functional, comfortable office environment when all environmental performance hinged on a single side.

Inspired by ideas of Disorder/Order, Unseen/Seen, and Closed/Open, the architects developed a conceptual framework that embraced contradiction. Their goal was to turn a rigid, closed shell into a façade that behaves as a living threshold—not simply a protective surface, but a spatial filter mediating between the indoors and the city.

Transforming the Façade into a Spatial Interface

The building’s original flat façade offered no potential for depth or environmental modulation. The architects reimagined this surface as a two-layer system, creating a mediating zone that is at once open, filtered, and protective.

1. Inner Transparent Layer

The first layer is composed of generous, clear windows that maximize daylight penetration. This layer establishes a strong visual connection from inside to outside, drawing sunlight deep into office spaces and enhancing clarity, openness, and orientation.

2. Outer Semi-Transparent Layer

The second layer, positioned outward toward the street, features:

• Wooden railings
• Steel planters
• A permeable vertical screen

This semi-transparent skin performs several critical functions:

• Filters harsh southern sunlight
• Introduces controlled natural ventilation
• Protects interiors from direct views
• Creates a buffer that enhances privacy without severing the building’s relationship with its surroundings

The space created between these layers becomes an active intermediate zone—a shaded, ventilated, atmospheric threshold that blurs the line between façade and functional space.

The Façade as an Urban Mediator

The dual façade system also enhances the building’s urban presence. Its depth and complexity animate the southern elevation with shifting shadows, greenery, and textured materiality. The building appears both solid and porous, closed yet open—reflecting the conceptual oppositions at the heart of the design.

Rooftop Continuity and Layered Transparency

The same architectural language extends to the rooftop, where transparency, semi-opacity, and environmental filtering define the spatial experience. The rooftop becomes an elevated interface with the city, offering views, fresh air, and light while preserving the users’ comfort and privacy. This creates a holistic architectural identity that flows seamlessly from façade to sky.

Interior Organization and Spatial Strategy

Inside, the design continues the theme of layering and controlled openness. Service cores, communal areas, and mechanical infrastructure are arranged with clarity and precision, ensuring uninterrupted visual flow and functional efficiency. The interior planning mirrors the façade’s logic—resolving contrasts by integrating them into a unified architectural system.

The Sarv Office Building is a masterful response to extreme site limitations, transforming a constrained shell into a refined and responsive architectural composition. Through its layered façade, the project achieves a delicate balance between light and shadow, openness and privacy, and urban exposure and interior comfort. Tamouz Architecture succeeds in crafting a building that not only adapts to its context but elevates the very idea of façade design in dense urban environments.
