The wooden veranda of Oleri Manor’s Master House (the late 19th century) suffered in a fire in 2000, and up to the autumn 2008 there was not launched its major renovation. Prior to this, presumably, around 1970, some elements of the veranda were superficially repaired and were in a significant contrast to the original structure, which is characterized by high-quality handmade crafts.
The restoration of the veranda was organized by the association “Oleri Manor” in 2008 within the framework of the project “Understand a wooden house”. During the restoration process 12 craftsmen improved their knowledge in the restoration of wooden buildings and their elements - windows, doors, stairs. Training sessions were led by specialists from Riga and Cesis. The rest of the time the work was carried out by two craftsmen, who also coordinated the application of the elements used in the training sessions.
TO SUCCESSFULLY RESTORE THE DISMANTLING MUST BE PHOTOGRAPHED
Already originally there was defined the concept in the restoration of the building - to maximally maintain the existing structure, for instance, in places, where it was possible, there was preserved the original painting, a well-preserved end of the decorative roof beam was “extended” with a newly constructed roof beam. Likewise there were carefully dismantled and reset under new putty the existing window panes. Metal fittings were carefully cleaned and, while hot, primed with lead minium. Missing parts were made by a blacksmith.
Later it turned out that the initial assessment of the building "relatively well-preserved" is incorrect. After the dismantling of the wooden veranda and inspection of its elements, it was clear that the scope of work considerably increased. Both the beams and poles in many places were unnoticeably rotten, which could not have been stated even by the most experienced masters unless dismantling the building. Completely anew there were constructed three roof beams, all the poles required the extension of the lower parts. Horizontal structural elements in the roof crown and wall panels on the invisible side were heavily rotten. The supporting beams had to be replaced. Floor boards had to be made anew. There was lost the solidity of the masonry structure in the plinth wall part of the building supporting the roof beams of the veranda.
While dismantling the building, the elements in a well-visible place were temporarily labelled with chalk. Later, while extending the elements, we labelled them anew in invisible parts. We developed the element labelling system during the dismantling, while drawing the roof and wall schemes. Later there turned out to be rather useful the suggestion made by the leader of the training to make as many photo fixations as possible, even for nodes and components of connections at that time understandable, because after seven months during the assembling work, a lot of this understanding was already lost! After the dismantling the components were transported to a workshop, where they were cleansed and the exact condition of each component was assessed. It must be said that our advantage was sufficient amount of time and, consequently, hasteless restoration deadlines.
Restore applying ancient techniques
In order to ensure a long-term viability of the historic buildings, in restoration work there shall be used traditional materials and methods of work. Also, restoring historic buildings, it is crucially important to use the construction materials available in the corresponding historical period.
For the extensions there was used air-dried pine wood, which had been stored in a stack for four years. Since for two of the newly constructed roof beams there was no timber of necessary dimensions, we produced them from the logs sawn in the winter of that year. While extending the ends of the beams, we created complex joining spots to highlight the craft quality of the building.
For the decoration there was applied linseed oil primer, the elements were several times, in some sections even four times, impregnated until there was attained a steady lustre. Largest cracks were filled with linseed oil putty “reinforced” with hemp fibre. We painted with linseed oil paint in two shades thus highlighting the visual lightness of the architectonic structure. We painted the ladder directly exposed to precipitation with linseed oil-tar paint.
It should be remembered that rags soaked with heated linseed oil are flammable and while drying can spontaneously combust. Also it is useful to remember that in poorly ventilated areas linseed oil contributes to the growth of mould.
A significant amount of work in the restoring of the veranda was made on the glazing of windows, where we used a 2 mm thick recycled glass. Some panes it was possible to make from the glass produced at the turning point of the 19th- 20th centuries, other – of the one made in the 30-ies of the 20th century. While planning work, the drying period of putty for the windows should be projected at least three weeks because it dries slowly!
It shall be kept in mind that even after the restoration all the elements of the building shall be checked and maintained on a regular basis - at least once a year, preferably in the spring, especially the windows, where the putty and painting shall be restored.
