跃层就是指住宅占有上下两层楼面，卧室、起居室、客厅、卫生间、厨房及其他辅助用房可以分层布置，上下层之间的交通不通过公共楼梯而采用户内独用小楼梯连接。跃层住宅指套内空间跨越两个楼层且设有套内楼梯的套型。跃层住宅是一套住宅占两个楼层，有内部楼梯联系上下层;通常在首层安排起居、厨房、餐厅、卫生间，好有一间卧室，二层安排卧室、书房、卫生间等。跃层式住宅的优点是每户都有较大的采光面；通风较好，户内居住面积和辅助面积较大，布局紧凑，功能明确;相互干扰较小。在高层建筑中，由于每两层才设电梯平台，可缩小电梯公共平台面积，提高空间使用效率。

高层住宅中虽然设置了电梯。不过，楼梯并不能因此而省掉，它仍然可以作为下面几层居民的主要交通工具，作为居民短距离(相邻几层)层间的交通工具，作为非常情况下的住户疏散通道。由此看来楼梯是不能缺少的，并且其设置位置和数量要兼顾安全和方便两个方面。首先要符合国家《高层民用建筑设计防火规范》的要求。要关注每部楼梯的服务面积及两部楼梯间的距离，在塔式住宅中。由于楼梯、电梯核心布局较为紧凑，可以采用一部剪刀楼梯，以取得两个方向的疏散口。其次，楼梯位置的选取与电梯的关系要适当，作为电梯的辅助交通工具，应与电梯有机的组合成一组。以便相互补充。对于板式或其他形式的住宅，在安排楼梯位置时，应考量主要的楼、电梯的位置对住宅平面及体形的影响。在有多向走廊时，如十字形、T形、H形等走廊。应尽可能放置在走廊的交叉点处，以便于多个方向人流的集中。当为一字形走廊时，应依照建筑物的长度和防火规范对安全疏散间距的规定选取适当的位置，以使楼梯的数量尽可能少。期望我的回答对您有用，题主觉得我回答得好就采纳吧！

一套住宅两个楼层是当下很多人的选取，这种跃层装修也是有讲究的，要设计好，下面就来跟大家说一些跃层装修的关注事项。
1、跃层装修分层要明确应按照主客之分、动静之分、干湿之分的原则进行功能分区，以满足主人休息，娱乐、就餐、读书、会客等各种需要，同时也要考量外来客人、保姆等的需要。功能分区要明确合理，防止相互干扰。通常下层设起居、炊事、进餐、娱乐、洗浴等功能区。卧房又可以设父母房、儿童卧室、客厅等，满足不同需要。
2、跃层设计之阁楼隔出一个二层的阁楼，无论是水平分隔还是垂直砌墙，都应该考量到加建结构的资料和承重、隔墙的厚度和高度的比例等。这类改造涉及精确计算、加固、切割等专业施工技术，改造前一定要查看设计公司是否具有“结构施工平安设计资质。
3、跃层装修之楼梯满足通行、疏散和家具搬运的要求楼梯梯段的宽度、平台的宽度、踏步的宽度及高度等尺度，要满足人行走舒适、家具搬运方便。2符合结构、施工、防火要求结构要满足承重的要求，楼梯构造尽量简单，以方便施工。楼梯使用的材料要为非燃烧体，满足建筑防火的要求。坚固安全、经济合理楼梯各组成部分的连接应牢固，楼梯栏杆、扶手连接牢固。楼梯的构造形式、材料的使用应符合经济的要求。关注美观不同的楼梯形式、结构布置和细部构造处理，将影响到楼梯与住宅的协调美观。
4、跃层装修突出重点在选取装修档次上，要依照主人的不同需求、不同身份进行设计，要突出重点。通常主卧室、书房、客厅、餐厅要豪华一些，客房、保姆房则应简洁一些。楼梯是这类住宅装修中的一个点睛之笔，旋转式的楼梯、宽厚的扶手，在空中轻灵蜿蜒地舒展着，引导你进入二层的空间。这样的着机会为你的居室增色不少。确定重点装修部分，分清投资装修的主次，非常重要。
