An appeals court has revoked permission for SANAA's restoration of the landmark Art Deco La Samaritaine department store in Paris. The plans, which would see a comprehensive overhaul of the 19th-century structure that finally shut its doors in 2005 following four decades in decline, would create an all-new shopping centre and luxury hotel as part of a 70,000m² mixed use development.

The project, commissioned by the LVMH conglomerate - which owns brands like Dom Pérignon, Givenchy, Louis Vuitton and BVLGARI - was halted because "the wavy, etched-glass facade proposed [SANAA] did not meet local planning requirements and was out of character with the surrounding buildings." It is understood that La Samaritaine will now appeal to the Council of State, France's highest administrative court. The city of Paris has mentioned in a separate statement that it would also support this latest appeal.

In a film for the BBC Magazine, Spanish architect Santiago Calatrava talks through his designs for the new St. Nicholas Church - the only non-secular building on the 9/11 Memorial site. The building, which broke ground last year, has been described by Calatrava as a "tiny jewel" for lower Manhattan, comprising of a white Vermont marble shrine sat beneath a translucent central cupola that is illuminated from within. The new church, of Greek Orthodox denomination, replaces a church of the same name which was destroyed during the attacks of 9/11. It is sited close to its original location on 130 Liberty Street, overlooking the National September 11 Memorial park and museum. With the building set to open in early 2016, Calatrava discusses the key conceptual ideas and references behind its unique, controversial design.

It has been revealed that the theme for the 2015 London Festival of Architecture (LFA) will centre around 'Work In Progress'. The festival, which is comprised of a series of events in and around the UK capital, seeks to "highlight the key role architecture plays in social, urban and cultural development." The annual celebration, which will run between the 1st and 30th June, will be jointly delivered by the Architecture Foundation, the British Council, New London Architecture, and the RIBA's London branch. Last year's 10th anniversary festival saw over 200 events ranging from walking tours and cycle rides, to exhibitions, talks, debates and films all addressing the theme of 'Capital'.

Five practices are the running to restore Charles Rennie Mackintosh's celebrated school of art in Glasgow. UK based John McAslan + Partners (who restored Mackintosh's last major commission), Scottish practice Page \ Park, and London and Hong-Kong based architects Purcell are all in the frame to lead the restoration of the Mackintosh Building amid a debate over how best to approach the rebuilding of the library and the areas of the building that were devastated by fire in May of last year. The selection of Avanti Architects and LDN Architects complete the rostra.

Work has begun on the demolition of the UK city of Birmingham's former Central Library, designed by home-grown Brutalist architect John Madin. The move by Birmingham Council to not retain the structure of the library, in spite of ideas and petitions put forward by numerous public groups (including one titled Keep The Ziggurat), has been widely met with disappointment among the architectural community. The BBC recently compiled some of the most interesting ideas for reuse which included, among others, transforming the concrete structure into a new English Parliament, an international trade centre, and an enormous space for rock climbing.

Madin, who passed away in 2012, had at least three of his major Modernist projects demolished during his lifetime. His design for Birmingham Library had been met with criticism from the likes of the city's Director of Planning and Regeneration of the time who described it as a "concrete monstrosity." Prince Charles famously described it as "looking more like a place for burning books than keeping them."

Great movements in architecture are usually set in motion by a dull societal ache or as a response to a sudden, unforeseen reorientation of a community at large. The Dutch city of Rotterdam - vast swathes of which were cast into oblivion during the blitz of May 1940 - has been at the forefront of many shifts in approach to the built environment. It is therefore fitting that the latest exhibition at the Nieuwe Instituut (formerly the NAi), simply titled Structuralism, is being held in the city that was recently named Europe’s best.

Furthermore, Dutch Structuralism is a timely subject for Dirk van den Heuvel and the Jaap Bakema Study Centre (JBSC) in Delft to tackle. With major civic buildings like OMA's extension to Rotterdam's City Hall taking shape, it appears that a resurgence of Structuralist formal thought is appearing in the contemporary city. The exhibition seeks to shine a new light on the movement by uncovering drawings, models and texts which profoundly shaped 20th century architectural thinking.

In a review of Rafael Viñoly Architects' 20 Fenchurch Street, which is also known as the 'Walkie-Talkie' or 'Walkie Scorchie' after it emerged that its façade created a heat-focusing ray strong enough to melt cars, Rowan Moore questions London's preoccupation with iconic buildings and its money-driven planning schemes. Using 20 Fenchurch Street as a key example, Moore argues that not only does the building seem "to bear no meaningful relationship to its surroundings," but its Sky Garden - a terrace at the top of the building which claims to be "the UK’s tallest public park" - is a symbol of a bewilderingly unbalanced economy.

A new exhibition and accompanying digital documentary on Cedric Price, a British architect, writer and educator who had a formative influence on architects such as Renzo Piano, Richard Rogers, and Bernard Tschumi, is open in The Netherlands. The exhibition, curated by members of Bureau Europa, introduces the work of Price by "presenting a cross-section of the elements of his inventive and singular practice" through sketches, project drawings, recorded talks, and first-hand accounts by staff, colleagues and friends. In addition, a series of selected projects present his "innovative models for industry, education, government, tourism, ecology and the house."

Guardian Cities have put together "the best of baked architecture" in a countdown of their favourite confectionary constructions. See London's Tate Modern rendered in precisely cut slabs of gingerbread alongside the curved shapes of New York City's Solomon R. Guggenheim Museum. Alongside these, food artists have been more inventive by building Paris's Louvre from translucent crystallised sugar glass and Mexico City’s Museo Soumaya from hundreds of spherical treats.

A team of students from Eindhoven University are set to build a forty metre high model of Antoni Gaudí’s Sagrada Familia out of 'ice'. The project, which follows their completion of the world’s biggest ice dome last year, will be constructed from pykrete and reinforced with wood fibres. The fifty-strong team will head to Finland on the 28th December 2014 to begin construction of the impressive 1:5 scale model, which will be built in only four weeks in order to officially open in the last week of January 2015.

Hello Nature, the most recent ideas-based challenge organised by Combo Competitions, asked participants to design a structure that celebrates nature on an expansive site in northern Sweden at the foot of Omneberget mountain. Located in an area known as the High Coast (Höga Kusten), the site sits within an UNESCO World Heritage Site. Designers were asked to "highlight the relationship between humanity and the rest of the planet" in putting forward proposals which "reconnect to nature." As a twist, entrants had to include both educational and recreational elements to their submissions. The entries, which range from a mountain of 'conservation drones' (with a control tower and charging station at its peak) to a collection of four extruded concrete plinths, all seek to explore our relationship with the wild when 50% of the world's population live in urban centres.

In 1970 the BBC followed architects Alison and Peter Smithson through the construction of their seminal housing project, Robin Hood Gardens (London). The impact of their architecture continues to resonate well into the 21st century, most recently in the British Pavilion at the 2014 Venice Biennale. Robin Hood Gardens was demolished in 2013, bringing an end to the Smithson's utopian vision. Listen to Alison Smithson explain the European Housing Condition (as the vision stood in 1970), the state of British infrastructure as it was, and hear Peter Smithson discuss the impetus for their most famous collective housing project.
