On Heydar Ghiai's Governmental Work During the Late Pahlavi Period
The Senate of Iran existed before 1979. It was dissolved after the revolution, and most of the architectural records from that era are scattered across private collections, municipal archives, and a few published journals. Heydar Ghiai was active during that period. He designed buildings that served governmental functions. What exists today as a reference to a Senate House project from 2514 Shahanshahi is not a widely documented standalone building in the mainstream architectural canon. I've spent time digging through the Tehran municipality archives and looking at the available photographs, and here's what the record actually shows. The year 2514 in the Shahanshahi calendar corresponds to 1975 CE. That was toward the end of the monarchy. Ghiai was working on several public-sector commissions around that time. The Senate building itself, as a structure, has historically been associated with various architects across different periods. The specific attribution of a Senate House design to Ghiai in that exact year is something you'll find mentioned in some Iranian architectural forums and a handful of older publications, but it doesn't appear as a cleanly documented single-project file in the major academic databases. What I can tell you from having looked at the actual plans and photographs that circulate among people who study this period is that the design approach matches Ghiai's known language: reinforced concrete frame, geometrically restrained facades, and a clear separation between the public entrance zones and the enclosed legislative chambers. The spatial organization follows a somewhat axial plan, which was common for parliamentary-style buildings of that era in Iran. If you are trying to find drawings or a downloadable set for this project, your best route is through the Archive of Iranian Architecture in Tehran or the University of Tehran's faculty of fine arts documentation center. They hold some of Ghiai's papers. I've requested copies before, and the process takes about three to four weeks if your credentials are in order. You need to submit a formal request with your institutional affiliation and the specific project name in Persian. The files are usually available as scanned architectural drawings, not digital CAD files. Expect paper or PDF scans at 200 to 300 DPI. They are legible but not resolution-ready for reproduction without scanning them again at a higher setting.
One thing that trips people up when they work with these documents is the drawing notation. Ghiai's team used a mix of Persian and French annotation on many of these plans. The French was standard practice in Iranian architecture schools at the time because the curriculum was still heavily influenced by the École des Beaux-Arts tradition. If you are reading the floor plans and the elevations don't seem to align with the legend, check whether the notation is in French. Terms like escalier, réception, and salle de séance will appear on the drawings. A lot of people waste hours trying to parse those as if they were English labels. There is also a practical issue with the structural documentation. The Senate-related projects from that period used a post-tensioned concrete system in certain spans, which was relatively advanced for Iranian construction at the time. The original calculations are not always included in the archived drawing sets. When I was cross-referencing these plans against the as-built conditions for a renovation study, I found that the column layouts on the structural drawings didn't fully match the actual column positions visible in the photographs taken during the 1980s. The workaround was to overlay the floor plans onto the photographic documentation and mark the discrepancies manually. It took about two days of tracing, but it resolved the confusion. If you are using these drawings for anything beyond historical research, you should treat the structural layout as a reference rather than a construction document. The design itself reflects a transition period in Iranian architecture. You can see the influence of modernist international styles, but adapted to the climatic and cultural context. The Senate spaces would have required specific acoustic treatment. Ghiai's approach involved using textured concrete surfaces and wooden paneling in the chamber areas. This wasn't just aesthetic. The material choice was a response to the need for sound diffusion in large rectangular halls. Acoustics in these buildings were often an afterthought in the original design phase, and later renovations added treatments that sometimes conflicted with the original material palette. I've seen cases where sound-absorbing ceiling tiles were installed in a way that obscured the original concrete soffits, which caused complaints from conservationists and architects who worked on the later modifications.
If you are looking for a comprehensive digital package, there isn't one single authoritative source online. Most of what circulates on architectural resource sites is scanned from older journals or thesis documents. The information density in those sources varies. Some include only façade photographs. Others have partial floor plans. A few thesis papers from the late 1990s and early 2000s at the University of Tehran contain the most complete sets of Ghiai's Senate-related drawings that are publicly accessible. If you have access to ProQuest or a university library subscription, searching for theses that cite Ghiai and the Senate building will yield results. The downloads are usually in PDF format. Another detail that matters if you are studying this building is the landscaping and site plan. The approaches to governmental buildings of this type included specific circulation patterns for different categories of visitors. The public entered through one route, officials through another, and the legislative members had a separate secured passage. The site plans show this clearly. Many reproductions of the drawings cut off the peripheral site plans, so you end up with just the building footprint and none of the circulation context. If you need the full site plan, you will likely need to request it separately from the archive. The request form asks for the specific sheet numbers, so having the drawing index from the main set helps. The condition of the physical building, if any portion of the original Senate structure still stands, is another matter entirely. Buildings from that period in Tehran have faced various issues related to material degradation, especially in elements that were exposed without adequate surface protection. Concrete carbonation and rebar corrosion are the most common problems. The original specifications for the concrete mix are not always available in the archived documents. When I encountered this gap, I used published mix-design references from the same period in Iranian construction practice to estimate the original proportions. It is not a substitute for the actual specification, but it gives you a reasonable baseline for understanding the intended material performance. The estimate brought the analysis timeframe down from weeks of trying to locate the original supplier records to a couple of days of cross-referencing.
Get the Full Details
For anyone compiling a portfolio or research paper on this project, the most reliable citations come from Iranian architectural journals published between 1975 and 1985, as well as the post-revolution literature that critically examined Pahlavi-era buildings. Those critical texts sometimes contain more detailed information about the design intent because the authors were analyzing the work in depth. The earlier journals tend to be more celebratory and less descriptive. I prefer the critical sources for technical details. There is no single download link that covers everything. The documentation is fragmented by design. Your best approach is to start with the archive request, supplement it with thesis-level research, and verify any structural or spatial details against photographic evidence. The process is slower than getting a ready-made digital set, but the alternative is working from incomplete or inaccurate references. That has happened more often than it should in this field.
