Completing the restoration of the monument, preserving its beauty and prestige and maintaining it are at the heart of the mission assigned to the Établissement public du Grand Palais.
 
Following an order of April 17 2007, the monument was endowed to the Établissement public du Grand Palais, which then became responsible for conducting any restoration work. The ÉMOC (a public works body specialised in heritage buildings) had been responsible for this in the past and had carried out the first stages of the restoration work.
 
The last stage in the exterior restoration work involved the restoration of the southern facades of the Grand Palais (overlooking the Cours-la-Reine). This was completed at the end of 2008. Interior restoration work is also planned. This concerns the Alexandre-111 rotunda, the Queen's rotunda, and the coachman's passage.

With its unique architecture, the Grand Palais still has great potential for development, notably thanks to hitherto unknown areas that are inaccessible to the public today. A major programme to redesign the interior, largely self-financed by EPGPCE, was launched in January 2008.
 
This programme will make it possible to double the available floor space and open refurbished areas to the public. These include:
 
- The VIP lounge, a magnificent area of 1,200 m2 with a glass roof in the heart of the Grand Palais. This was the setting for the first exhibitions and the scene of countless events. On March 12 2009, access to the VIP Lounge from the Nave, sealed off since 1947, was reopened at a specially organised media event. This marked the start of restoration work on this superb facility that will be able to host high-profile events again as from the end of 2010.
 
- The south-east gallery is an area of 700 m² that has been out of use since 1999. Restored in 2009, it will be born again with its initial volume and glass roof and available for events and exhibitions. The first exhibition, devoted to tags and graffiti, took place in the area, prior to restoration in April and May 2009.
 
Operating the renovated areas as of 2010 will involve responding to three goals: enhancing and diversifying the programme of the Grand Palais, providing more modular areas and developing the business of hiring out these areas.
 
The design programme will be carried out alongside the events that take place in the Nave, without causing any disruption.

Whilst considered by all as totally unique, the Grand Palais still suffers from a lack of facilities and comfort for visitors. Yet, welcoming the public at large in the best possible conditions is one of the institution's key missions.
 
The Grand Palais' 2008/2011 action plan includes the following facilities and services:
- A new Web site launched in June 2008;
- A new Grand Palais voice server ;
- New signage inside the Nave's peristyle (the avenue Winston Churchill entrance) with information boards introduced in 2008: four boards in French and English provide information related to key dates in the history of the Grand Palais, its events programme, missions and accessibility. Another large panel outlines the history of the building.
- Work in progress includes new facilities for the disabled, the creation of exterior signage, a book and souvenir shop and guided tours, new cloakrooms and a ticket office.
 
A new book on the Grand Palais, entitled Le Grand Palais, monument-Capitale, written by Yves Saint-Geours was published in February 2009 as part of the Découvertes Gallimard series. It is the first step in a new publication policy undertaken by the EPGPCE to produce books for the widest possible audience at affordable prices while attaching the greatest importance to the quality of the scientific information, the editorial and iconographic content.
