Renting a flat in Salt Lake, New Town, or South Kolkata often comes with restrictions on painting or structural drilling. Renters can still achieve a custom, premium interior look using non-permanent products. Self-adhesive wallpapers are easy to apply and peel off without damaging the plaster. Another great option is lightweight 3D PVC wall panels that can be attached using double-sided mounting tape and silicon glue, allowing you to remove them when shifting flats. These simple tricks can turn plain rental walls into premium luxury spaces without violating your rental agreement.
