If you are looking for an interior designer on the internet, you will look at numerous websites and references. Most of the cases even the details can be found concerning to the given service for the money: consultation, design documentation, visiting shops, 3D visualization etc. Most of them are obvious. However, the parts of the design documentation (if there is a detailed list at all) mean a little to most people. It can be useful to know these in general.
Floor plan: if there is no official floor plan, the interior designer measures the property and makes a dimensioned floor plan. It contains among others: sizes of rooms, sizes and places of doors and windows, ceiling height, widths of walls, occasional level differences and orientation. The scale is 1:50 (flat) or 1:100 (bigger house).
Demolition-construction plan: these can be on one plan or separated, depending on plans. Commonly two different colors show the changes. The plan contains the demolitions and buildings of walls with dimensions, compared to the original floor plan. The scale is 1:50.
Floor and wall covering plan: in the case of floors it is a color floor plan, in the case of walls it is a sectional view. It contains the type, size, offset and allocation of the covering, size and color of interstice and distance dimensions (if necessary). The scale in the case of floor is 1:50, in the case of wall is 1:20.

Electric plan: it is a plan visualized on the floor plan, which contains the dimensioned places of lamps, sockets, switches and electric outlets (including binding height also). Related furniture is also displayed. The scale is 1:20.
Custom made furniture plan: front and side views (more sides if necessary) of the uniquely made furniture which contain all the dimensions. The material of furniture, details of handles, type of fittings and built-in details can be showed if necessary. The scale is 1:20.

If there is any part in the description or in the offer given by the interior designer, which cannot be understood, do not hesitate to ask for further information. Since one of the bases of the good professional contact is the proper communication.
