如何画精美的户型图?

\documentclass{article}
\usepackage{tikz}
% 加载常用库：箭头、几何、标注
\usetikzlibrary{arrows.meta, shapes.geometric, decorations.pathreplacing, calc}

% 定义样式：简化重复代码
\tikzset{
    % 墙体样式：粗黑线
    wall/.style={line width=2pt, black},
    % 门窗样式：细黑线
    door/.style={line width=1pt, black},
    window/.style={line width=1pt, black, dashed}, % 窗户用虚线
    % 家具样式：浅灰色填充
    furniture/.style={line width=1pt, black, fill=gray!10},
    % 尺寸标注样式
    dim/.style={line width=0.5pt, black, <->, font=\small}
}

\begin{document}
\begin{tikzpicture}[x=0.5cm, y=0.5cm] % 缩放比例，方便调整大小

% ========== 1. 绘制墙体（外框+内部分隔） ==========
% 户型外框：矩形 (0,0) 到 (20,15)
\draw[wall] (0,0) rectangle (20,15);
% 客厅-卧室分隔墙：竖线 (8,0) 到 (8,15)
\draw[wall] (8,0) -- (8,15);
% 卧室1-卧室2分隔墙：横线 (8,8) 到 (20,8)
\draw[wall] (8,8) -- (20,8);
% 卫生间分隔墙：(15,8) 到 (15,15)
\draw[wall] (15,8) -- (15,15);

% ========== 2. 绘制门窗 ==========
% 入户门：(0,5) 到 (1,5)（门宽1单位）
\draw[door] (0,5) -- (1,5);
\draw[door] (1,5) arc (0:90:1); % 门的开启弧度（90度）
% 客厅窗户：(4,15) 到 (7,15)（虚线）
\draw[window] (4,15) -- (7,15);
% 卧室1窗户：(8,12) 到 (12,12)
\draw[window] (8,12) -- (12,12);
% 卫生间门：(15,10) 到 (16,10)
\draw[door] (15,10) -- (16,10);
\draw[door] (16,10) arc (0:-90:1);

% ========== 3. 绘制家具（简化示意） ==========
% 卧室1的床：矩形 (9,9) 到 (13,11)
\draw[furniture] (9,9) rectangle (13,11) node[midway] {床};
% 客厅的沙发：矩形 (2,2) 到 (6,4)
\draw[furniture] (2,2) rectangle (6,4) node[midway] {沙发};
% 卫生间的马桶：圆形 (16,9)，半径0.5
\draw[furniture] (16,9) circle (0.5) node[below] {马桶};

% ========== 4. 尺寸标注 ==========
% 户型总宽度：下方标注 (0,-1) 到 (20,-1)
\draw[dim] (0,-1) -- (20,-1) node[midway, below] {20m};
% 户型总高度：右侧标注 (21,0) 到 (21,15)
\draw[dim] (21,0) -- (21,15) node[midway, right] {15m};
% 卧室1宽度：(8,-2) 到 (15,-2)
\draw[dim] (8,-2) -- (15,-2) node[midway, below] {7m};

试了一下现有的宏包, 都相去甚远, 有没有什么好的宏包推荐一下呢?
