The weekend magazine (How to spend it) is not suited for Calibre and epub because of its layout. But you can read this magazine for free on its own website.
House & Home is of course one of the weekend sections and part of this problem.
What you can do (as I have): Tell FT that the weekend sections "Life & Arts" and "House & Home" are not displayed on the webpage
http://www.ft.com/intl/uk-edition on weekends. Tell them that this page should show the weekend sections on weekends and the regular "Arts" section during the week.
