CROSSARCHITECTURE Completes Middle Envelope Apartment

CROSSARCHITECTURE has completed the Middle Envelope Apartment, a residential project led by architect Mehrdad Makaremi. The project's name signals its organizing idea. The design treats the apartment's boundary — the space between inside and outside — as its central architectural element.

The title itself is the clearest statement of intent available. "Middle Envelope" names a strategy common in contemporary residential design: wrapping living space in an intermediate layer that mediates light, privacy and climate between the street and the interior. Makaremi's project places that layer, rather than the plan or the facade alone, at the center of the design argument.

What do we know about the project?

The confirmed facts are these:

• Project name: Middle Envelope Apartment
• Architecture firm: CROSSARCHITECTURE
• Lead architect: Mehrdad Makaremi
• Typology: Residential — an apartment

The project's publication record establishes its completion and circulation within the architecture press. CROSSARCHITECTURE and Makaremi are credited as the sole authorship team, with no named collaborators or engineers listed in the available record.

What does "middle envelope" mean as a design strategy?

The term describes an intermediate spatial layer. In apartment design, an envelope typically separates conditioned interior space from the exterior. A "middle" envelope inserts a third zone between the two — a buffer that can shade glazing, temper airflow, frame views and stage transitions between public and private realms.

It's a concept with practical consequences. A layered boundary can reduce solar gain without heavy curtains, soften street noise and create semi-outdoor rooms that function in multiple seasons. For a compact apartment, that buffer zone effectively adds usable area without expanding the building's footprint — a common driver for the approach in dense urban housing.

What does this change for the resident? In envelope-led apartments, the boundary itself becomes inhabitable: window ledges deepen into seats, circulation doubles as a threshold gallery, and light filters through a graded sequence rather than a single pane of glass.

A note on this coverage

Built Current reports here on the project as documented by its publishing record. The source material for this item is limited to the project's title, authorship and typology. We have not reproduced descriptions of the apartment's dimensions, materials, location, client brief or construction dates, because those specifics do not appear in the available record.

That constraint is worth stating plainly. Architecture coverage too often fills factual gaps with speculation about finishes and square meters. This article won't do that. What can be verified: the project exists, CROSSARCHITECTURE executed it, and Makaremi carried the design authorship.

Why the name carries weight

Naming a project after its envelope is a positional move. It tells critics and peers where to look: not at the plan diagram, not at a signature form, but at the threshold condition. Firms that name projects this way — and CROSSARCHITECTURE's title follows that pattern — are usually arguing that the boundary performs the design's core work.

For Makaremi, the project adds a residential case to a portfolio whose profile circulates through international architecture media. Readers tracking envelope-driven housing — from Tehran to Rotterdam — will recognize the type immediately.

Built Current will update this story as confirmed project details, including location, area and material specification, become available from CROSSARCHITECTURE.
