Hey Im an architectural designer, based in Silver Lake, Los Angeles I can help you. 

We do plan to draw up a full contract once we have the completed site and architectural plans so he'll be able to do a cost breakdown of the construction. 

Your numbers could range from $10-150 per square foot, depending on:- Specific Scope of Work (SOW)- Your experience- Specific architectural design decisions- Level of finishes- How the project is managed (you or a GC)- Time of year- Type of contractors used- Your negotiating skillAnd lots of other factors. 

I am 24 and I've recently graduated College with my B.S in Architectural Engineering.

For a roofing repair of that size, $7900 seems close to the high-mid range for some of the projects we've done recently in NC.For 1250-15000 sq ft houses, it's been costing under $6500 in Raleigh for architectural shingles. $11,000-$12,500 for fastener metal one's but I don't like those. $7900 is a little rich, but some markets are like that.

Coming from an architectural background, I now use Midjourney to create a visualization for potential development/remodeling of properties, ChatGPT for reading/writing and Analytics, and sometimes Github's co-pilot to create custom code for my workflows. 

Therefore, it is essential for both homeowners and investors to keep a close eye on upcoming development projects in the area, as they could have a profound impact on the real estate market.Historical Significance:Properties with historical significance or unique architectural features often carry higher price tags due to their cultural and aesthetic value.

Soft costs excluded like tap fees, architecture, plans, etc I bet you could get it under $150 a sq ft. 

My wife and I own a local Architecture firm and have been doing a lot of work on these conversions.

Here's the backdrop....For the past 20yrs I've ran a residential design/build company. 10yrs ago I was able to get into REI and now have 6 properties total (2 personally (1-ABNB / 1-SFH LTR)/ 4 (LTRs) in a LLC with a partner), and manage 2 additional properties as the property manager. 2yrs ago I decided to drop the building side of design/build, and now I just do architectural design and REI.
