1. Preliminary concept
First, the desired appearance and, accordingly, the materials used are determined. It is important to understand that in addition to the main cladding of the building, you will have to plan the cost of installing window slopes and ebbs. Also, the cost of installing a new parapet will come out if the roof is flat, and if you have small cornice overhangs, then they may have to be increased.
Of course, you can hire a designer to draw everything approximately or exactly for you. At this stage, no one can tell you the exact cost of the work, but only the order of numbers. Alas, this is just the beginning.
2. Coordination of the facade and its changes by the state executive authorities
For example, in Krasnoyarsk there is a procedure approved by the city administration for approving the passport of the facades of buildings and structures, with the exception of individual housing construction. Therefore, your lawyer should check the existence of such requirements for your object.
In Krasnoyarsk, as part of the documents, it is necessary to provide information on the color scheme, on the materials used, lists and layouts of additional equipment, elements and devices, architectural lighting scheme, etc.
This means that it is easier to make a project than not to do it. But in fact, the project needs to be done. Now check it out.
3. Design
3.1. Design surveys, encumbrances
When constructing the facade, we increase the overall dimensions of the building. This value can be different, from 100 mm to 700 in my memory. In addition, often in the process of facade reconstruction, the owners decide to additionally arrange canopies over the entrances to the building or even porches – accordingly, this is an indent from the building up to 2 meters. Behind the facade, the blind area can also shift.
Therefore, at the design stage, it is necessary to check whether, after the reconstruction of the facade, the violation of the red lines, the boundaries of easements and the security zones of engineering networks will not occur – otherwise, you will have to dismantle everything that you mount in such areas.
3.2. Purpose, fire safety class of the building, height of the building
The parameters indicated in the title of the paragraph affect the requirements for the materials used, the arrangement of individual components of the facade structure, and further on the cost of work and materials. As a rule, most facing materials (granite, plaster, metal and composite panels) meet such requirements, but all kinds of PVC do not. The same with insulation, mineral wool – does not burn, polystyrene foam – is limited in use. In addition, heaters have restrictions on the height of the lined structures. In general, there are enough subtleties.
