Construction cost can be calculated for capital gain tax or not

If i purchased a plot in 2001, and constructed a house on it. and sold it in 2022 january. 

Now for the purpose of calculating capital gain i have to only minus the cost of plot from the sale value and the result is my actual capital gain or i can also deduct expenses incurred in construction of house, modular kitchen, under ground water tank, rain water harvesting, modular kitchen and some other expenses.
