St. Louis Symphony Orchestra's Powell Hall / Snøhetta

Susanna Moreira — Tue, 07 Oct 2025 06:00:00 +0000

Beginning in 2019, Snøhetta, in collaboration with Christener Architects, Schuler Shook, BSI Constructors, and Kirkegaard, led the expansion and modernization of the St. Louis Symphony Orchestra's historic performance space, Powell Hall. To ring in the hall's centennial in 2025, the organization embarked on an ambitious 64,000-square-foot expansion with Snøhetta as design architect and landscape architect. The project will allow the concert hall to be more fully accessible and open to the community, creating a facility that supports and nurtures the creative process from idea to performance.

Pilar Caballero — Wed, 17 Sep 2025 10:00:00 +0000

The refurbishment, a collaboration between Buenos Aires–based AdamoFaiden and Rome–based Supervoid, transforms a five-story early 20th-century building in Rome's San Saba neighborhood. The project reinterprets the historic structure while adapting it to contemporary living.

Catalog House / Pend Architects

Pilar Caballero — Thu, 11 Sep 2025 10:00:00 +0000

Pend has completed a comprehensive renovation and integration of two former flats into a single family home in the Trinity suburb of Edinburgh for long-term clients and collaborators, Dixie and Ralf, owners of independent multi-brand design store, Catalog Interiors in Stockbridge. The project focuses on the functionality of Catalog House as a forever family home and as an intuitive backdrop for hosting, balancing inviting and open spaces with more personal, family oriented areas.

Thornbury House / Healy Ryan Architects

Pilar Caballero — Tue, 09 Sep 2025 02:00:00 +0000

The original house is a simple weatherboard bungalow with charming stained-glass windows and internal timber detailing. However, at the rear, an uninspiring renovation from a few decades past was not making use of the north-oriented rear yard. Our brief was to update the house to accommodate a young family and establish a richer connection with the surrounding landscape and garden.

Twin Pitches House Extension / Atelier Baulier

Pilar Caballero — Mon, 08 Sep 2025 10:00:00 +0000

London-based architecture practice Atelier Baulier has completed the deep retrofit and extension of a previously underperforming and shabby Edwardian house in Ealing. Twin Pitches now stands as a joyful, light-filled four-bedroom, highly energy-efficient family home. The clients, Phoebe and Paul Sprinz, had a clear ambition to improve the spatial quality and comfort of the house, making thoughtful gestures to optimize and enhance the existing footprint. Setting out to build their forever home, the clients worked with Atelier Baulier to reimagine and extend the house, prioritising a low-impact, future-forward approach while creating a space full of personality and heart.

Casa Luna / iHouse estudio

Valentina Díaz — Fri, 05 Sep 2025 15:00:00 +0000

Casa Flor was commissioned by a friend of the studio, Nacho Mazzini, proud owner of the "yellow house with a round window" built in 2021. Fascinated by the use of that home and attentive to the evolution of his family dynamics, he wished to add a new module on the adjoining plot next to his first iHouse, located in Punta Ballena near the Arboretum. The intention was to create an intimate and reflective pavilion—a space for contemplation—while avoiding the challenges of building a traditional house directly beside his current home.

Mess Hall / Architecture Architecture

Pilar Caballero — Wed, 03 Sep 2025 03:00:00 +0000

At the end of the school day, some family homes feel more like community centres: classmates and neighbours bustling in and out, sharing in homework, hobbies, art projects, and food; practicing music, preparing impromptu dinners, concocting magical potions, all the while regaling with stories of the day's adventures.

Jetvan Extension / Design Work Group

Miwa Negoro — Fri, 29 Aug 2025 19:00:00 +0000

This project is an expansion of one already dear to both the client and our team. The client approached us with an elongated site that housed the existing 'Jetvan' residence, crafted a few years ago. The intent was to accommodate another home for the extended joint family within the same plot.

Casolare Biordo Vecchio / Studio Bressan

Pilar Caballero — Wed, 27 Aug 2025 10:00:00 +0000

Nestled among the hills of Asolo, Casolare Biordo Vecchio is a regeneration project of an old rural building, transformed into a contemporary residence that preserves the authenticity of its origins.

Sobremesa House / Studio McW

Whitberry House Extension / Pend Architects

Pilar Caballero — Wed, 06 Aug 2025 10:00:00 +0000

Pend has completed a sensitive renovation and expansion of Whitberry, a Grade B listed Georgian farmhouse in East Lothian, Scotland. Working alongside the clients-turned-project-managers, the Leith-based architects unified the home's fragmented rear elevation and introduced light-touch interventions to the ground floor to support contemporary family life. In contrast to its charming pink frontage, the back of Whitberry reveals a curious arrangement, a patchwork of historic and somewhat haphazard additions characterized by reddish sandstone and brickwork, each a record of the masonry techniques of its respective eras. The arbitrary nature of these successive add-ons had resulted in a difficult, cellular interior layout, requiring the family to pass through several rooms to reach the garden.

Casa E.T. Renovation and Extension / Studio Bocchi

Hadir Al Koshta — Tue, 22 Jul 2025 10:00:00 +0000

The project concerns the renovation and expansion of a farmhouse located inside a courtyard on the crest of the hills of the Piedmont area of the Reggio Emilia Apennines. The stone building, dating back to the early 1900s, had already been the subject of renovation and consolidation interventions over time that had led to the creation of reinforced concrete terraces in the areas towards the valley, and in recent times to the renovation of the roof and the addition of a concrete and wood portico on the east side.

Sofie House / MADAM architectuur

Hadir Al Koshta — Thu, 03 Jul 2025 10:00:00 +0000

Sofie is a house full of character, located in Dilbeek, Belgium, in a very green environment. The house needed to be completely renovated, but also partly extended. Many beautiful elements were present and carefully preserved: wooden floors, moldings, decorative wooden elements around windows and doors, and stairs. Above all, the existing volume was restored.

Vidy Theater Renovation and Extension / PONT12 architectes

Hadir Al Koshta — Tue, 17 Jun 2025 12:00:00 +0000

Designed by Max Bill in 1964 for the National Exhibition, the theatre was initially intended for just six months of use. Its acquisition by the City of Lausanne, under the leadership of director Charles Apothéloz, and the continuation of its theatre activities have made it possible to conserve part of the large pavilion. Several successive teams have made Vidy an international reference, a major contribution to the cultural influence of Lausanne.

Hugo’s House / Ian Moore Architects

Pilar Caballero — Wed, 28 May 2025 02:00:00 +0000

This project involved alterations and additions to one of a row of 6 identical Victorian terrace houses, which have a cross stair between the two original bedrooms on the upper level. The cross stair typology makes opening up the front two rooms on the lower level to form a large living and dining space more difficult, so it was decided instead to create more living space in a new rear extension. The former rear extension, containing the kitchen and laundry had a poor connection to the rear courtyard and was demolished to make way for a new extension, which also included a new bedroom on the upper level.

Lapland Central Hospital Extension / Verstas Architects

Hadir Al Koshta — Thu, 15 May 2025 03:00:00 +0000

Originally completed in the 1980s, the Lapland Central Hospital was designed by one of Finland's most renowned hospital architects, Reino Koivula. The extensions double the current premises of the hospital, including e.g., emergency outpatient clinic, observation ward, operation rooms, psychiatric wards, and facilities for several supporting functions. The extensions create conditions for extensive operations synergy, transforming the hospital campus into a more integrated and efficient whole.

Clarke House / Austin Maynard Architects

Pilar Caballero — Wed, 14 May 2025 07:00:00 +0000

Clarke is the renovation and extension of a single-storey weatherboard cottage in Northcote, once void of light, definition, separation, and all hope of personal space.

LIH Residence / Atelier Rampazzi

Pilar Caballero — Fri, 02 May 2025 10:00:00 +0000

The project involved the renovation with extension of a secondary dwelling in the residential suburb of Ascona. The district in question is located close to the lake and is characterised by detached residential buildings surrounded by vast, lush green spaces. Originally, it was a single-family dwelling organised on two levels with a one-storey secondary volume attached to the building, which included storage rooms and a car park. A quite inconvenient feature of the old building was that the two levels were not connected internally, but one always had to go outside to move from one floor to the other. Initially, the plan was to build a multi-family building, but since both the market, the investment required, and the urban structure hardly lent themselves to a large volume, we turned to a radical and complete renovation of the old house. The intervention consisted of reorganizing and extending the living spaces, regularizing the volumetry and fragmenting the architectural volumes, in such a way as to distinguish the various bodies, built at different times, both in terms of genesis and function.

GIG Residence / Atelier Rampazzi

Pilar Caballero — Thu, 01 May 2025 06:00:00 +0000

The project involved the renovation and extension of a secondary residence located on the residential outskirts of Ascona, a small village in the Locarno region. The neighborhood, surrounded by vegetation and characterized by independent buildings with large green spaces, is located near the lake, offering a unique naturalistic context, overlooking one of the oldest golf courses in Switzerland. The original building was a single-family house organized on one floor with tiny spaces, two bedrooms with separate external entrances, all unfortunately in a precarious state of maintenance. Volumetrically, it was unbalanced and clearly assembled volume after volume with addition after addition, without any clear planimetric intentions or even less defined spatial concepts. A patchwork situation that, in consideration of the client's requests, the regulations, and other aspects, such as the flood hazard zone of Lake Maggiore, led to a radical and general intervention.

The Domcenter / peter haimerl . architektur + Studio Clemens Bauder

Hadir Al Koshta — Thu, 10 Apr 2025 12:00:00 +0000

The neo-Gothic cathedral in Linz is one of the largest church buildings in Austria and was constructed between 1865 and 1924. In 2024, the diocese celebrated the cathedral's hundredth anniversary. However, Catholic communities face challenges: membership numbers are declining, and the church's societal relevance is decreasing. While many congregations respond with budget cuts or the sale of sacred spaces, the Archdiocese of Linz embraces innovation and openness.

KIM Oflage Studio / Delve Architects

Pilar Caballero — Wed, 02 Apr 2025 10:00:00 +0000

A bespoke garden studio for a growing family in South London, KIM-oflage by Delve Architects provides a colourful space for sleep, work, painting and relaxing. Homeowners Kit and Imogen had loved working with Delve Architects on a timber-clad extension to their Victorian terrace home in Nunhead in 2018. However, with a growing family, their choice was either to move or solve their need for more space in a different way.

Belleville Sara Weill-Raynal Nursing Home Reconstruction and Extension / Avenier Cornejo Architectes

Hadir Al Koshta — Sat, 29 Mar 2025 11:00:00 +0000

Rechristened Sara Weill-Raynal as a tribute to the Parisian doctor and Socialist activist of that name, the former Belleville nursing home in the 20th arrondissement welcomed its new residents on 17 May after a five-year refurbishment programme. Revelations about living conditions in certain nursing home have made elderly care into a burning issue. In this troubled context, the refurbishment of the Sara Weill-Raynal facility by Avenier Cornejo offers spatial responses that improve the lives of both residents and care staff. The renovation is one of the construction and restructuring initiatives carried out by the Centre d'Action Sociale de la Ville de Paris (CASVP) whose aim is to improve the quality of care facilities across Paris.

BS Hof House / Alpina Architects

Pilar Caballero — Thu, 20 Mar 2025 06:00:00 +0000

Nova Ponente, a small town in the province of Bolzano, sits nestled among the mountains at an altitude of 1,300 metres above sea level. Home to around 4,000 people, it is also where our client, the protagonist of this story, was born and raised—at BS Hof, the family farmstead, surrounded by animals and nature. As she grew older, the need for a space of her own, where she could live with her future family, became clear. Yet, the desire to remain connected to this place, to continue being part of the farm's daily life, was the foundation upon which this project was built.

Townhouse Extension / LAC Architecture

Pilar Caballero — Tue, 18 Mar 2025 19:00:00 +0000

The project involves a wooden extension of a townhouse on the outskirts of Paris. From the outside, the silent and modest architecture blends into its environment while presenting a singularity that asserts its contemporaneity.
