A section of the west facade of the Onwentsia Club

A section of the west facade of the Onwentsia Club in Lake Forest by Harrie T. Lindeberg with his typical tall roof, here of quarry tile, and simple lines. He moved away from the formal classicism of his architect mentors to synthesize myriad influences into his own style, drawing from Scandinavian design and vernacular Swedish houses, English cottage vernacular, and French and American Colonial sources. His houses all share a simplicity, steep roofs, long, unbroken rooflines modeled in slate, tile, or thatching, low-lying masses or one-story wings, and rich, textured building materials.

Beautiful baroque Roskilde Mansion (1736), with ye

Beautiful baroque Roskilde Mansion (1736), with yellow-washed masonry and red tile roofs, replaced a bishop's palace which had stood on the site since the Middle Ages. The four-winged complex consists of a two-story main wing, two one-story lateral wings, and a curved gate wing opening to the Stændertorvet. The four wings are connected by curving galleries. Dating from the 13th century, the Gate of Absalon, which connects the mansion to the apsis of Roskilde Cathedral, is the only surviving part of the bishop's palace. We love the very Lutyens-like entrance screen....classicism combined with the vernacular. #copenhagen #travel #wanderlust #peterpennoyerarchitects

Among the many historic figures carved in the stone facade of our Massachusetts project, is this mystery musician who appears to be playing a violin to accompany the ballad of the traveling architect...! photo: @ericpiasecki #peterpennoyerarchitects #ad100 ⁠

Happy New Year! Looking up at the vaults of the entry at our Czech cubist house in Ohio...the red and orange glass mosaic walls are overlaid with a fretwork of glittering silver. The mosaic was inspired by the banking hall at One Wall Street where Ralph Walker worked with artist Hildreth Meière. Todd Anderson's nickel and cast-glass chandelier hangs from a laylight at the center of the ceiling. Photo: @ericpiasecki #peterpennoyerarchitects

For a new fieldstone structure built into the slop

For a new fieldstone structure built into the slope of a seaside property, we designed its entrance as a rustic laid board Dutch door with wrought iron strap hinges. The monolithic stone lintel frames the opening and doesn't rely on the typical steel angles⁠. Photo: @ericpiasecki #peterpennoyerarchitects #ad100 #stonehouse #dutchdoor #frontdoor ⁠

In connecting two apartments to create a duplex, we positioned the new spiral stair on the center line of the existing south-facing window. This follows our method of planning apartment interiors to suggest that the building was designed from the inside out. The bronze balustrade with its guilloche-like design was fabricated by @laforgedestyle.

We are so proud to be the architects for the new incarnation of Guild Hall @guild_hall. The architecture by Aymar Embury will shine again as we recapture the original charm of the theater, and, working with theater design experts Auerbach Pollock Friedlander, and acoustical consultants Akustiks (who worked on David Geffen Hall) will improve sight lines, accessibility, the proscenium, and acoustics.

Progress on our reconstruction of a 19th c. villa overlooking a harbor on the North Shore of Long Island. We added this oculus which will flood the stair below with light from a new cupola. The arched and round window beyond is a grouping typical of the era. #sitephoto #progress #longisland

A favorite detail from a trip to Copenhagen in late summer.....owls of Athena guarding an entrance to a dormitory of Copenhagen University. We stumbled into this courtyard and were quite taken by these hefty looking carved stone sentinels. #copenhagen

A roaring fire in the dining room of our new house with @reddkahoi in the Hunting Valley of Ohio. @degournay's views of India cover the room and a plaster bolection mantel sits between a blind arch and an arched doorway.

Quick speed through the office today….some new old things, like the model for a 4-stroke engine and Vitruvius’ prescient design for a tower (of war in his plate). Some new samples for what will be metal details on the exterior of a new house in the country. Then, a visit to the green marble drawer; through to our interiors department and some of their colorful new inspirations; and finally flipping through some loved built work (minus the sea creature column capital…sadly). #peterpennoyerarchitects #attheoffice

Soft light in the upstairs study of an historic house in Massachusetts we collaborated on with @max_rollitt. We restored every original room, salvaging and bringing back to life finishes and materials with the least invasive methods possible. All of the wood surfaces in the house, including the elaborate historic wood paneling of this room, were cleaned, hand-oiled and hand-waxed to bring back their original luster and color.

Progress at our new Spanish-style house in Palm Be

Progress at our new Spanish-style house in Palm Beach. The cornice is made in cast stone inspired by terracotta tiled eaves found on traditional buildings in Spain. The exposed wood above will be sealed and caped with copper flashing before the green glazed clay barrel roof tiles are installed. Beneath the cornice, the exterior walls will be white stucco. We can't wait to show you more of this house as it moves towards completion. #palmbeach #newhouse #architecturaldetails

A circular stair in progress in a new house in Palm Beach! This is the metal substructure that will support limestone steps and a plaster stringer.

Some favorite images of architecture, details, patterns, floors, critters, and colors from Copenhagen. The classicism has a pleasing simplicity and purity but the details are whimsical.

P.V. Jensen-Klint’s otherworldly Grundtvig Churc

P.V. Jensen-Klint’s otherworldly Grundtvig Church, the ultimate apotheosis of the Danish medieval parish church, built up brick by brick over 27 years (initial inauguration in 1927, completed 1940), based on hundreds of minutely detailed drawings showing the exact location of each of its over 5 million bricks. Inside, the uniformity of material continues and the same yellow-white bricks make up every surface: the vaults, arches, everything. Last slide shows the medieval Church of St. Mary in Elsinore, with its stepped gable, an enduring inspiration to J-K.

We love how the magiscope refracts the light and changes the view of the building across the street. #peterpennoyerarchitects #ad100 #roundwindow #cupola$

We built this fieldstone, barn-like structure into the slope of the land of a project in Massachusetts. The new outbuildings, carried out in a different style and material than the main house, give the impression that the property has been developed over time. Inside is a gym, garage, and apartment.

Site visit to a special project in Long Island where the roof, dormers, cupola, and trim of this 19th century captain’s house are all new based on historical research and imagination. Exciting to see this house come back to life! #sitevisit #longisland #historichouse
