[Tex/LaTex] Cover letter with Sender and Recipient on the left-hand-side

coversletterheadlettersletterspacing

I would like to use the documentclass letter but only moving the sender -field to the left-hand-side.

Minimal example from here:

\documentclass{letter}
\usepackage{hyperref}
\signature{Joe Bloggs}
\address{21 Bridge Street \\ Smallville \\ Dunwich DU3 4WE}
\begin{document}

\begin{letter}{Director \\ Doe \& Co \\ 35 Anthony Road
\\ Newport \\ Ipswich IP3 5RT}
\opening{Dear Sir or Madam:}

I am writing to you on behalf of the Wikipedia project (http://www.wikipedia.org/),
an endeavour to build a fully-fledged multilingual encyclopaedia in an entirely
open manner, to ask for permission to use your copyrighted material.

% The \ldots command produces dots in a way that will not upset
% the typesetting of the document.
\ldots

That said, allow me to reiterate that your material will be used to the noble end of
providing a free collection of knowledge for everyone; naturally enough, only if you
agree. If that is the case, could you kindly fill in the attached form and post it
back to me? We shall greatly appreciate it.

Thank you for your time and consideration.

I look forward to your reply.

\closing{Yours Faithfully,}

\end{letter}
\end{document}

Example what I have now for English speakers i.e. the letter's format:

This is what I need for Finnish speakers

where you have the sender and recipient on the left-hand-side but otherwise the same.

I have tried the documentclass \documentclass[a4paper]{scrlttr2} but it is too overkill – increasing linespace and puts an extra line for name and address.

Official model of Finnish Document Class, here original source

This part is made for the request of Johannes B in his comment.

The document standard is called "Asiakirjastandardi" in Finnish, wiki here.
The document is classified by the document model type SFS 2487 (asiakirjamalli in Finnish).
It is maintained by Suomen Standardisoimisliitto SFS ry and online here.

You have to patch \opening:

\documentclass{letter}
\usepackage{hyperref}
\makeatletter
\renewcommand*{\opening}[1]{\ifx\@empty\fromaddress
  \thispagestyle{firstpage}%
    {\raggedleft\@date\par}%
  \else  % home address
    \thispagestyle{empty}%
    {\begin{tabular}{@{}l@{}}\ignorespaces
      \fromaddress 
      \end{tabular}
      \par\nopagebreak
      \vspace{2\parskip}%
      \raggedleft\begin{tabular}{l@{}}\ignorespaces
      \@date 
      \end{tabular}\par}%
  \fi
  \vspace{2\parskip}%
  {\raggedright \toname \\ \toaddress \par}%
  \vspace{2\parskip}%
  #1\par\nobreak}
\makeatother
