Alvar Aalto Paimio Sanatorium

 

This small exhibition - described by Designmuseum Danmark as a "pop-up exhibition" - is based around two chairs from the permanent collection - Armchair No 42 and the Paimio Chair - also known as The Ring Chair - designed by Alvar Aalto and both used in the Paimio Sanatorium. The hospital in south-west Finland designed by Aalto was built specifically for the treatment of patients with tuberculosis - and was completed in 1933.

The chairs are displayed with historic photographs and copies of drawings that have been selected to show how important the hospital was and to put those two chairs in context.

Aalto was born in February 1898 so he was four years older than Arne Jacobsen. The exhibition does not compare directly the work of the two architects but there are marked and very important similarities. They grew up and then studied as architects in a period of massive social, political and economic changes in Europe and in a period that saw rapid advances in technology and industrial production that had a huge impact on architecture and furniture design. Political changes were more dramatic for Aalto because Finland only emerged as a nation, independent from both Sweden and Russia, in 1918 after a revolution.

 

Both architects, through the 1920s and through their first commissions, absorbed and readily adapted their designs to building in the relatively new material of concrete and the new techniques of construction that went with that material … so generally buildings with piers in concrete that supported concrete floors and, as a consequence, with freedom to experiment with external and internal walls that were no longer load bearing and with few restrictions in terms of height in buildings that could be constructed quickly.

Crucially, both architects worked on all aspects of a project … so not just the plan and structure of a building but all details of windows, door handles, light fittings and, for both men, designs for furniture.

They each achieved a uniform aesthetic in their buildings, and that was important, but it was also driven by the need for efficiency and an attempt to rationalise construction and manage costs - to produce as much as possible off site and to reduce the number of variations and options for the same reasons … so what became important was how they put together the parts and that was determined by function and not a hierarchy of fittings as in so many public and domestic buildings before the 20th century.

 

Here, in this exhibition, the two chairs show how Aalto was at the forefront of technical developments in furniture manufacture. His grandfather was a forester and taught at the Evo Forest Institute south of Tampere and Aalto himself developed a specific technique of cutting down into a length of squared-off timber, interlayering with thin slips of wood inserted into the cuts and with glue and steam bending and formed the timber for the frame for chairs and tables and other furniture.

He was one of the first designers to exploit and develop the use of plywood which again was bent - rather than used as flat sheets - to create a continuous surface for the seat and back of a chair but he also extended the bend or curve of the plywood to form a rounded support for the head and a rounded support for the back of the legs.

It is important to look carefully to see how the plywood shell of the seat and back and the bent-wood frame are joined together - with lugs or tabs in strategic positions on the edge of the plywood that fit into slots in the frame - and how crossbars link the frame on each side but also support the plywood at critical points.

 

Because of its topography and climate, Finland does not have the variety of native timbers for furniture making and house building that are found in Sweden and Denmark so the form of the chairs is not an odd whim of aesthetics but was necessary to be able to use native rather than imported timber - to do what was possible with native birch - a relatively small tree.

And the design of the chairs - and the distinct features of the building - reflect the nature of the disease treated at the hospital.

Tuberculosis was a contagious disease that effected the lungs but could also infect bones and the nervous system. By the early 20th century it was the cause of death of 7,200 people a year in Finland or about 13% of mortality year on year in the country.

When the hospital opened, treatment was based around providing patients with good nutrition and bed rest in the early stages of the disease and then with sun and fresh air although bright light and noise effected many sufferers badly.

The chairs are relatively low and long so the sitting position is close to reclining and the bent-wood frame and plywood provide a level of flexibility for long periods sitting in the sun or fresh air. The construction in wood was lighter than anything comparable that used tubular steel, so the chairs could be turned easily to be angled towards the sun and they were not upholstered to reduce contamination. Note that the Paimio Chair has narrow horizontal slits cut through the head rest so that air could circulate around the face.

The first private Sanatorium in Finland was opened in 1895 and the first owned by a federation of municipalities opened in 1914 but after passing a Tuberculosis Act in 1929 eight large sanatoriums were constructed with total of 2,500 beds and Paimio was the last to be completed in 1933 for 296 beds for patients from 52 municipalities including the city of Turku with an allocation of 100 beds. Because tuberculosis was contagious, the hospitals were generally set in countryside away from towns … the Sanatorium at Paimio was 20 kilometres east of Turku set in an area of woodland.

With the discovery of anti biotics, it became possible to alleviate and then control the spread of the disease and in 1960 the sanatorium buildings were modified and converted for use as a general hospital.

 

The exhibition at Designmuseum Danmark in Copenhagen continues until 21 January 2018

Paimio Sanatorium 1929-33

 

Alvar Aalto Architect volume 5 Paimio Sanatorium 1929-1933, Alvar Aalto Foundation and Alvar Aalto Academy (2014)

 

 

One of twenty eight volumes published by the Alvar Aalto Foundation and the Alvar Aalto Academy to cover the work of the Finnish architect.

The format, with pages set landscape, allows generous space for an attractive layout but also gives an appropriate page size for the reproduction of design drawings for the Sanatorium and its fittings and furniture.

The book is a compilation of separate essays:

Paimio Sanatorium written by Teppo Jokinen, includes some of the preliminary drawings by Aalto that were entered for a competition for the building in 1929 and drawings for the expansion of the scheme, a decision made before construction started, when the city of Turku joined with the original municipalities. To expand the facilities, two extra floors and a roof terrace were added to the main block of rooms for the patients to treat up to 296 patients from 52 municipalities with up to 100 of those beds available for the city of Turku.

The arrangement of blocks on the site has a long but narrow main range with bedrooms and balconies on six floors angled to face south-east and south to benefit most from the sun and so rooms and balconies look out over the forest. A separate block containing administration spaces and a dining room, library and consulting rooms and surgeries was set behind but linked to the main block by an entrance hall with lifts and the main staircase. There was also a boiler house, ancillary buildings and housing for physicians and other staff that are reminiscent of the housing for teaching staff at the Bauhaus in Germany and the housing built for the exhibition in Stuttgart in 1927.

 

It was a complicated building with innovative features including windows with baffled ventilation to ensure fresh air without drafts; heating systems that were designed to ensure air circulation without uncomfortable areas of high heat; a complicated lighting system including shades and baffles - reminiscent of the work by Poul Henningsen in Denmark at the same time - and of course the famous washbasins in each room that were placed on the wall towards the corridor so they could be serviced from outside without disturbing the patients but were also designed to be splash and sound proofed because many suffering from tuberculosis became very sensitive to intrusive sounds. Aalto, and what seems to have been a relatively small office, achieved all this within a tight time frame as the building was ready to take its first patients by 1933.

The essay Paimio Interiors by Kaarina Mikonranta discusses the importance of light and colour in the programme of therapy and looks at everything Aalto designed inside from furniture and light fittings, to the door handles that were designed so that the coats of doctors would not snag as they pushed through the doors. Given that most patients occupied rooms with just two beds then there would have been rather a lot of opening and closing doors through an average day.

Some lighting came from an earlier project - so the pendant lights were shown at the Helsinki Minimum Apartment exhibition in 1930 - but 10 new models were produced Oy Taito Ab.

 

Paimio Sanatorium - repairs and modifications by Ola Laiho is a useful summary of the subsequent changes made to the building and its fittings. Many were undertaken by Aalto or by the partnership that continued after his death. A new operating theatre was added in 1958 and then, after the Sanatorium was converted to a general hospital in 1960, the distinctive balconies and sun deck were converted to interior spaces, with that work completed in 1963, and, perhaps the most obvious change, the glass walls of lifts were replaced with concrete.

Paimio Sanatorium Project Description quotes in full an important summary of the project by Alvar Aalto himself.

To complete the volume, there are photographs compiled by Maija Holma and three essays - Tuberculosis in Finland in early 20th century by Arno Forsius; Early days of the sanatorium (1860-1902) by Anne Marie Chatelet and The Sanatorium in Europe in the 1920s and 1930s by Jean-Bernard Cremnitzer - that are general but set out important context for planning for this type of special hospital that became common throughout Europe in the late 19th and early 20th century.

chairs in plywood by Alvar Aalto

Through the 1930s the Finnish architect Alvar Aalto designed a number of chairs that had a shaped seat in plywood. One of the earliest designs, Chair 23 produced in 1929, had a simple tubular metal frame that supported the simple plywood seat but, as the designs became more sophisticated and more complicated in form, Aalto used a bentwood frame that was again, for many of the chairs, cantilevered. 

One of the chairs that went into production was Armchair 41 from 1932 that Aalto designed for the tuberculosis sanatorium in Paimio.  These chairs were strong, stable, relatively light - so they could be moved onto the balconies where patients could sit in the sun - provided good support and were low with the sitting position slightly reclined and of course without upholstery they were seen to be more hygienic because they were relatively easy to clean. 

Their simple construction also meant that they could be manufactured in a workshop with no cabinet making skills. That did not mean that the chairs were crude or unsophisticated but the form came directly from the materials ... note that the shaped seats were generally held into the frame with a tab or ear of the cut plywood set into a long, narrow slot cut into the bent birch frame.

Armchair 403 also from 1932 is a dining chair or desk chair with four legs both using a similar plywood seat to the metal-framed chair. The wood frame has slightly angled legs with a cross bar and an arm rest across the top that has a joint cut like a basic version of the comb with veneer layers at the top of the leg of the Stool 60 designed the following year.

Armchair 42 and Armchair 402 also designed in 1932 were cantilevered chairs and both low and rather long from front to back. The most striking feature of all these chairs is the silhouette.

 

 

 The 1934 site has good photographs of original pieces and, unusually, good details of construction. Well worth checking out.
