Advice on renovation for inter-terrace

[2coe 0]

I have just purchased an old 2 storey inter-terrace and is planning to do a major renovation.  Will be grateful for any advice on the renovation in terms of airflow/ ventilation for the house and bug control. I am currently living in a patio unit and these are the 2 areas I’m concerned about for ground floor living.

for airflow, try to ensure that there is a path for the air to flow from front to back and vice versa. airwells are optional since if there's no way for air to come in and out in the first place via cross ventilation, having a airwell is useless.

for landed house, there's always going to be bugs and even rats. just hire a pest control company who goes over every month to do some preventive measures and also lay mouse traps. nothing much you can do since the pest can come from your neighbours even if your house is super clean.
