A drawing, a signature, and a room that carries both.

THE MAKING — The hotel occupies the granite octagon of the 1851 Charles Street Jail. The rotunda is the original volume: iron galleries stacked around a central void, with the granite walls and circular windows left in place. A new tower of guest rooms was built alongside, so the jail holds the public rooms and the tower holds most of the beds.

WHOSE HANDS — The conversion was led by CambridgeSeven, with Ann Beha Architects (now Annum Architects) as preservation architect and Alexandra Champalimaud on the interiors. Suffolk Construction delivered the build. Cell doors, gratings and catwalks were taken out, restored and put back as fittings rather than as cells. The cupola, removed in 1949, was rebuilt from the original drawings.

MADE AGAIN — The jail fabric is maintained as a listed building: granite, windows, the rebuilt cupola and the ironwork are repaired in kind. Public rooms in the rotunda are refitted on a hotel cycle, and guest floors in the new tower are refurbished independently of the historic shell. Lighting in the void is replaced as fittings fail, without touching the galleries it hangs from.

MADE ONCE — The octagon, the granite walls and the decision to keep the rotunda open rather than floor it over were set when the jail was converted in 2007. The new tower's position against the old wings is fixed by the site between the river and the hospital. Those two bodies cannot be rearranged.

WORTH ASKING — Ask whether a room is in the historic jail wings or the new tower, and whether the rotunda galleries are open to walk.

THE MAKING — The hotel occupies a 1901 neo-Gothic building on Van Baerlestraat that was built as a savings bank and later housed the Sweelinck Conservatorium. The courtyard is now an atrium: a steel and glass lid spans the brick walls, and a new insert of walkways and rooms stands inside that covered volume. Guest rooms occupy both the restored historic floors and the new construction.

WHOSE HANDS — Architectenbureau J. van Stigt restored the historic fabric. MVSA Architects designed the new atrium structure as a contrast of dark steel against the old brick. Interiors are by Piero Lissoni. The two offices worked the building as a pair: one returning the 1901 detail, the other adding only what the hotel needed and could not take from the old plan.

MADE AGAIN — The brick envelope is maintained as a monument. Glass, seals and the steel frame of the atrium are serviced as a modern roof. Public rooms under the glass are refitted commercially, and guest rooms turn over on an ordinary hotel cycle. The conservatory history is kept in the name and in the restored rooms, not in any remaining musical fit-out.

MADE ONCE — The 1901 plan, the courtyard and the decision to roof it rather than fill it were set when the hotel opened in 2012. The atrium is a thermal envelope as well as a room, and that coupling of old wall to new lid cannot be taken apart without losing the building's one move.

WORTH ASKING — Ask whether a room looks into the atrium or onto the street, and whether the brick courtyard walls are visible from it.

THE MAKING — The hotel joins two brewery buildings in Carlsberg Byen: the Maltmagasinet, a nineteenth-century malt store, and Lagerkælder 3, a 1960s lager cellar whose circular windows now read across the facade. The two structures sit on different centuries and were never designed as one hotel. Rooms, a roof terrace and a wellness floor were cut into the industrial volumes without flattening their section.

WHOSE HANDS — Arkitema led the conversion, with Christoffer Harlang as collaborating architect. The Maltmagasinet was originally the work of Vilhelm Dahlerup; Lagerkælder 3 was designed by Svenn Eske Kristensen. Old silos and machine traces were kept as interior objects rather than stripped. The name is Ottilia Jacobsen's, the brewer Carl Jacobsen's wife, which is a naming decision rather than a building one.

MADE AGAIN — Brick, the circular window frames and the silo interiors are maintained as listed industrial fabric. Guest rooms and the roof restaurant are refurbished on a hotel cycle. Where a circular window unit fails it is remade to the cellar's original geometry rather than replaced with a rectangle.

MADE ONCE — The two buildings, their different dates and the circular windows of the lager cellar are fixed. The hotel opened in 2019 on that pairing, and the Carlsberg City District plan around it decides how far anything can be added. The roof terrace sits on a structure that was never drawn for dining.

WORTH ASKING — Ask which building a room sits in — the malt store or the lager cellar — and whether the circular windows are in that room.

THE MAKING — The hotel occupies the former Helsinki county prison on Katajanokka, a radial block whose oldest parts date from 1837. Cells were joined in pairs to make guest rooms, so the plan is still the prison plan: thick masonry, a narrow window, a corridor that once was a gallery. Public rooms were fitted into the former halls rather than built as a new wing.

WHOSE HANDS — Lundwall Architects redesigned the cells as rooms and later returned for lobby and room refurbishment. The conversion opened in 2007. The masonry, the cell dimensions and the window openings were treated as given; furniture and bathrooms were specified to fit those dimensions rather than the other way around. Nothing structural was opened that the monument listing forbade.

MADE AGAIN — Rooms are refurbished within the cell envelope: surfaces, bathrooms and furniture change, the window opening does not. The corridors and the public halls are reworked as the hotel's use of them changes. External masonry and the prison wall around the block are repaired in kind.

MADE ONCE — The radial prison plan, the cell size and the island site were set in the nineteenth century and settled again when the building became a hotel. Two cells make one room, and that arithmetic cannot be changed without cutting the walls. The surrounding wall still decides how the building is approached.

WORTH ASKING — Ask whether the room is a paired cell with the original window, and how the old prison corridors connect to the entrance.

THE MAKING — The hotel occupies a nineteenth-century neo-Renaissance building that was a French hospital and convent, with a new wing added beside it. The chapel remains a room: stained glass, stone, a chequered floor. Guest rooms are split between the heritage volume, with high ceilings and arched openings, and the new wing, which is a separate construction against the old stone.

WHOSE HANDS — John Pawson and the Israeli architect Rami Gil designed the conversion together. Pawson's office is credited with the measured new work against the stone; Gil with the local construction and the joining of the two wings. Furniture in the chapel and lobby includes specified pieces rather than built-in joinery, so the historic room can be read apart from what was placed in it. The hotel opened in 2018.

MADE AGAIN — Stone, stained glass and the chapel floor are conserved. The new wing is maintained as ordinary hotel fabric: rooms refurbished, seals and glass replaced. Public rooms in the old building are rearranged around the same openings. Lighting in the chapel is replaced without cutting the stone it is fixed to.

MADE ONCE — The hospital building, the chapel and the street line in Jaffa are fixed. So is the decision to add a new wing rather than hollow the old one further. Those two bodies, old and new, were set at the conversion and cannot be restacked on this site.

WORTH ASKING — Ask whether a room is in the heritage wing or the new wing, and whether the chapel is in use as a public room that day.

THE MAKING — The hotel is a 1901 cooperage — a barrel factory — on the Williamsburg waterfront. The conversion left the brick walls, the arched windows and the heavy timber ceiling grid, and poured a concrete floor through the old bays. Rooms are the factory bays with a bed and a bath inserted. A roof bar sits on top of the original structure rather than in a new tower.

WHOSE HANDS — Morris Adjmi Architects designed the conversion. Interiors were developed with Workstead. The building was opened as a hotel in 2012 by Andrew Tarlow's group. Brick was cleaned and left, timber repaired, and new services were run in the thickness the factory already had. Windows were rebuilt in the arched openings rather than enlarged.

MADE AGAIN — Brick, timber and the arched windows are maintained as the permanent layer. Rooms are refurbished inside that envelope: beds, baths and lighting change, the bay does not. The roof bar is refitted as a public room that takes weather and use. The concrete floor is the one new surface that runs through the whole building and is repaired as a floor, not as decoration.

MADE ONCE — The factory footprint, the bay spacing and the waterfront wall were set in 1901. The hotel opened on that geometry in 2012. A barrel works does not become a tower, and the roof bar is the only addition the old structure was asked to carry.

WORTH ASKING — Ask which floor the room is on, and whether the arched windows face the street or the river side.
