Self employed using home office business deduction- how do I report capital improvement to home .ie. new windows

S.E and write off a home office, which is where I do most of my work.  I spent over 17K to have my home windows replaced.  I looked at IRS Tangible property regulations on repair vs improvement.  It is lengthy and I do not understand.  Do I put them in on my Bus Assets under intangible?  TT says to put capital improvements in that section but it is not made clear where.   I also spent another 11K on gutters, new fascia, etc but that is on a loan of which I am paying monthly.  Can I report what I have paid this year as an asset also or do I handle that in a different way, like an expense.  Thank you.  It makes a huge difference in my tax bill and I do not want to mess it up.
