@Mike-Amos Having a proposal is highly competitive and I am not paid yet.
I started working with the Tehran ICH Center (intangible Cultural Heritage Center)

Another alternative for the brown color (my suggestion) was facade bricks;

Also, these are quality texture resources.

You are right.

The only good news is that the fire code is highly strict!

@Mike-Thanks for your compliments. I would be more than happy to share what I know. Okay's do it. If anyone is interested may write here or DM me.

Although very realistic, it lacks minor properties such as specularity and SSS. By the way who cares about those minor things, especially regarding architectural representation.

@L-i-am Yes, there is a very comprehensive strict code, yet BKZ of bribery and lack of enough control during the building phase, rarely people obey that. They provide some documents to get the legal permissions to start building and then they build something else and pay the penalty. i.e. regularly someone must not exceed 60% of their land and let 40% be free for green space. But you rarely see this is done. They build more and pay the penalty. That is why I say it is chaotic. The only serious limitation is height limitation, Usually up to 2 extra floors could be built by paying a fine, and over that must be demolished.

Yes Liam, This is what some constructors do. They usually do not pay for the design as they think this is a waste of money. Some builders after some while think they know how to design, so they bypass the design and start building. Then they decide about the facade. They think this is the only place an architect is needed. This is very chaotic IMO and in reality, they have to pay for many "redo"s as they face many conflicts between MEP and architecture. They pay for those demolition works and do not consider it as a waste of money but they do not pay for the design. This is very chaotic but the prevailing construction culture here, unfortunately.
maybe it is because Architecture in its modern term, is rather new here compared to civil engineers. Years ago almost all design jobs were done by civil engineers. It takes time to change such an odd culture.

Oh yes, otherwise it would be a real nightmare to texture such a thing.

Thanks for sharing. Yet my resource images are BW and I change them due to the composition needs.

Thanks, mates, This is heart-warming! I was thinking of having one-on-one sessions, in case anyone is interested in drawing/watercolor.

I know it is odd to design a facade apart from the plan/building but it has become a norm here. recently I had a facade design suggestion and here is the result.
Changes on the 1st floor has been due to the client.

The rusted one... It seems a nightmare to be textured!

And here is another shot from the Grand Hotel.

here is a detail from the painting.

I started painting old Tehran.

@jo-ke I am wondering how do you do the texturing!

Now I am available for one-on-one sessions. Please do not hesitate to reach me out for drawing or watercolor sessions:

@tuna1957 Thanks mate. It is a basic course, by the way it may provides you with a few minutes of creative and quality time!
Feel free to share, please!

Fine render.
Yet time to revise construction codes, tastes, or details... I am wondering why they repeat the same style/material/construction skills... while witnessing that is vulnerable to fire... It is like making iglos in tropical climate, just because I used to iglos....
