I am using biblatex and biber with the authoryear styles for my documents. Now I've been asked to format my bibliography like this: enter image description here

It looks like a mixture of the numeric style (labels left of the entry) and authoryear. However, the length of the label is much longer and might for the first line of the entry to wrap. How can I archieve this?

edit: biblatex-ext has this function built in as introcite=label. And so the code below can be replaced with

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[british]{babel}
\usepackage{csquotes}
\usepackage[style=ext-authoryear, backend=biber, introcite=label, dashed=false]{biblatex}
\addbibresource{biblatex-examples.bib}

\setlength{\bibitemsep}{0.5\baselineskip plus 0.5\baselineskip}
\setlength{\introcitewidth}{6em}

\begin{document}
\cite{sigfridsson,worman,geer,knuth:ct:a}
\printbibliography
\end{document}

The styles of biblatex-ext can be used as drop-in replacements of the corresponding standard styles.

Try this

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[british]{babel}
\usepackage{csquotes}
\usepackage[style=authoryear,backend=biber,dashed=false]{biblatex}
\addbibresource{biblatex-examples.bib}

\makeatletter
\setlength{\bibitemsep}{0.5\baselineskip plus 0.5\baselineskip}

\newsavebox\ay@labelbox
\newlength{\labwidthsameline}
\setlength{\labwidthsameline}{6em}

\newbibmacro{labelwidthbib}{%
  \begingroup
  \delimcontext{cite}%
  \DeclareFieldFormat{bibhyperref}{##1}%
  \csuse{blx@hook@cite}%
  \csuse{blx@hook@citekey}%
  \citetrackerfalse\pagetrackerfalse\backtrackerfalse
  \defcounter{maxnames}{\blx@maxcitenames}%
  \usebibmacro{cite}%
  \endgroup
} 
%-----------------------
\newbibmacro{kicklabel}{% 
  \sbox\ay@labelbox{\usebibmacro{labelwidthbib}}%
  \global\togglefalse{blx@insert}%
  \ifdim\wd\ay@labelbox>\labwidthsameline
    \leavevmode\newline
  \fi
}

\defbibenvironment{bibliography}%
  {\list
    {\usebibmacro{labelwidthbib}}%
    {\setlength{\labelwidth}{\labwidthsameline}%
     \setlength{\leftmargin}{\labelwidth}%
     \setlength{\labelsep}{\biblabelsep}%
     \addtolength{\leftmargin}{\labelsep}%
     \setlength{\itemsep}{\bibitemsep}%
     \setlength{\parsep}{\bibparsep}%
     \renewcommand*{\makelabel}[1]{##1\hss}}}%
  {\endlist}%
  {\item\usebibmacro{kicklabel}}
\makeatother

\begin{document}
\cite{sigfridsson,worman,geer,knuth:ct:a}
\printbibliography
\end{document}
