Google Chrome by default does not show the Home button before the address bar. If you frequently want to visit the web page which you have set as home page then you can always make Google Chrome show the Home button.
To unhide the home button in Google Chrome, Click the wrench icon and select options from the list of available menus.
In the Google Chrome Options screen, navigate to Basics tab then to Toolbar section.
Now mark the checkbox with the label as Show Home button. This would now display the home button before the address bar as shown below
