隨著時代生活壓力增加，以及依據2024年中華民國內政部戶政司2月統計資料顯示，國內老年人口總數高達18.5%，台灣已於2018年邁入高齡社會。在這樣的時空背景下，我國三代同堂是最能展現出傳統孝道家居的生活方式，華人素來習慣有兒孫子女的陪伴生活，故有許多的家庭選擇三代同堂的居住模式，以分擔家務和照顧責任。本研究旨在探討在此種生活方式下，三代宅裝潢格局設計不僅是為了呈現室內空間的品味與美觀，更重要的是須考慮到各個家庭成員的需求性和隱私性的設計規劃思維。
本研究透過深度訪談和案例研究的方法，分析了不同家庭成員在共同居住所遭遇的問題；研究發現，適度地分隔住戶成員生活空間的裝潢設計能夠提高家庭成員之間的居住舒適度和私密性，同時又能夠促進家庭成員之間的互動和合作。這種裝潢設計方式為現代三代同堂居住提供了一種新的解決方案，有助於緩解家庭生活中的壓力和矛盾。
研究結果表明，在當今社會背景下，裝潢設計對於三代同堂居住模式的成功實施至關重要。將一戶分割成兩個獨立單位的裝潢格局設計不僅能夠滿足家庭成員的各種需求，同時也有助於提高居住品質和家庭和睦。
