To modernize an 80s house without losing character, start by lightening the envelope with high-LRV paint colors to brighten walls and ceilings. Keep original features like curved walls and coved lighting intact to maintain personality. Unify flooring throughout the main areas to create flow, and install layered lighting using warm bulbs and multiple light sources. Design a smart kitchen layout incorporating a two-kitchen setup to enhance entertaining without gutting the space. This blend keeps your home modern, bright, and cozy with original charm.
