One of the features to retain is the flooring, especially when it comes to marble or parquet floors. Installing new floors will incur a large sum of renovation expenses due to the amount of work involved and man-hours required. Rather than going for a full-scale renovation for your floors, you can always opt to polish (marble floors) or varnish (parquet floors), which will cost only about 10% of actually replacing them entirely.
Doors and door frames are features that you can choose not to replace if they are still in good condition. Most doors and door frames have an evergreen and universal design, allowing them to fit seamlessly with almost every interior renovation design concept. Therefore, unless their structure is compromised or they are no longer functional, they should be on the “To Keep” list.
