I would build up the posts on the bottom so they are thicker/ look more architectural?

I am an Architectural Designer and I am new to the real estate world.

Fortunately, an architectural professional with knowledge of the local building code will be able to work with you to develop a new layout that makes the house flow better and creates a more appealing space for the buyer.The architect will help you avoid some of the major pitfalls in changing the layout:You must NEVER, ever, replace a load-bearing wall.

From an aesthetic point of view, I'm a fan of combining historic and modern features - too much 'antiqueyness' in a place doesn't grab me, but I also hate to see great architectural features and workmanship discarded.

Here's he declaration you'd need to sign:https://www.sanjoseca.gov/DocumentCenter/View/2124-  Even if you could get approval to build yourself, the cost of architectural drawings (by someone who knows local codes), permitting and impact fees would would be half of your budget

I'm 25 and work in the architecture/engineering industry.

The property must be historically significant for its architecture, archaeology, or historic associations to be eligible.

Sourcing capital, finding and analyzing deals are my strengths (although I love architecture/design).

Don't worry so much about little imperfections in that room. you will be keeping an original architectural detail of the home. buyers love wood floors. refinish in that room will cost same as cheap laminate.    

I am extremely glad to have this as a reference for well constructed, and well planned architecture that leaves room for profit.Sincerely,Mark
