# How to add vertical space after the recipient's address in a letter?

I have written a letter. My problem is I don't know how to add a vertical space only between the recipient's address and \conc.

If I put vspace*{2cm}, the vertical space is add on the first line of the letter, before the sender's address.

If I add \setlength\openingspace{2cm} , a space is added between the recipient's address and the concname (it's ok) but also between the concname and the opening.

I would like only to shift all that is after the recipient's address.

Do you know how can I do?

Thank you so much!

\documentclass[11pt]{lettre}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[francais]{babel}

\institut{sender}

%\setlength\openingspace{2cm}

\begin{document}
\begin{letter}{%
\vspace{0.75cm}

My company

}

\conc{Bla bla}
\renewcommand{\nrefname}{}
%\nref{}%Références de la lettre, de votre point de vue}

Big bla bla bla etc.

\closing{Je vous prie d'agréer, Madame, Monsieur, l'assurance de ma parfaite considération.}

\end{letter}
\end{document}


The institut file (for the to-adress) is "sender.ins". The code is below:

• Welcome to TeX.se, and thanks for adding an example document. As posted, however, it doesn't compile without errors and requires some external file. You can add external file(s) to the document using \begin{filecontents}{<filename>} ... \end{filecontents}. – Alan Munn Apr 26 '17 at 13:38
• Thank you for your comment. I added the institut file's code. It can compile now ;) – Beretta Apr 26 '17 at 13:54

You can use the etoolbox package to patch the \concdecl command and add the space directly to it.

\usepackage{etoolbox}
\pretocmd{\concdecl}{\vspace*{2cm}}{}{}

• Thank you. Unfortunately this code adds a vertical space on the top of the page, between the border and the first row of the sender's adress. – Beretta Apr 26 '17 at 14:26
• Thank you. I don't see any differences when I change the length in \vspace*{2cm} or, even, when I comment the line. Maybe we haven't the same configuration. However the package etoolbox is installed; so I don't understand. – Beretta Apr 27 '17 at 8:01
• I successed when I changed \concdecl from your code to \concline. So the solution is \usepackage{etoolbox} \pretocmd{\concline}{\vspace*{2cm}}{}{} . Thank you so much! I would never have found it alone. – Beretta Apr 27 '17 at 8:23
