If $X$ is your space and $o$ the joining point (I assume the metric is the geodesic one), it's obvious that $X$ is isometric to its tangent cone at $0$. More generally, if $X$ is a proper metric space and and has a 1-parameter subgroup of non-isometric dilations fixing a point $o$, then every tangent cone of $(X,o)$ is isometric to $(X,o)$ as pointed metric space. | |
