Interior design study of two dwelling units, Velký Borek

Two dwelling units in Velký Borek sit in one building mass and share an identical layout, three bedrooms plus an open-plan living room with a kitchenette. Each has 119.87 m² of usable floor area over two above-ground storeys, and the units differ only in the size of their plots. For Vavřina & Co s.r.o. we prepared the interior design study for both, from the Revit model and 21 drawings to a 17-page material schedule with four bathroom options.

The two units on U Olší street have the same floor plan and the same areas. The brief was not the building but its interior, meaning the fit-out and the materials inside a layout that was already fixed, worked up from documentation handed over by the client. The ground floor holds an entrance lobby, a plant room, a hall, a WC, a pantry and a 42.28 m² open living room with a kitchenette. Upstairs there are three bedrooms, a dressing room, a hall and a 5.70 m² bathroom, and each unit has a 16.45 m² terrace. Because the layout does not move, everything else follows from it. The furniture has to fit the room, not the other way round.

Both units were modelled in Revit with real manufacturer components placed in the model, from windows and doors through sanitary ware and appliances to lighting and furniture. Every deliverable then came out of that single model. The consultation set runs to 21 sheets, covering an axonometric view of the house, floor plans of both storeys, dimensioned plans with room areas, electrical and service connection plans, two sections, four elevations and detailed elevations of the assemblies in the hallway, bedroom, bathroom and living room. Windows received a sheet of their own, with the opening type and width noted for each. The model was exported to IFC and OBJ and used to render nine interior scenes.

The client received a 17-page material schedule, issued separately for unit 1 and unit 2. It moves from the site plan and floor plans through the kitchen and its joinery breakdown to the dining area, living room, entrance hall and bedroom, and closes with four bathroom options and an element list. Every room covered in the document pairs a render with the materials specified for it, naming the actual decor, tile and flooring. The element list is grouped into sanitary ware, radiators, electrical fittings, end fittings and doors. That level of detail lets the client brief a kitchen supplier or a tiler directly, without further explanation.

Project challenges

Two units built from one model look like an easy win until handover comes up. The material schedule was issued twice, separately for unit 1 and unit 2, even though the units differ only in plot and garden area, so each document stands on its own. The bathroom was the second question. At 5.70 m² the tile format drives the result more than the colour does, which is why four options were prepared, backed by a dedicated sheet of 3D views comparing 10x30, 30x60 and 60x60 formats. The third was trade coordination. Electrical and service connection plans had to line up with the kitchen units and with the underfloor heating, down to the socket for the cooker and oven and the worktop cut-outs for the sink and the induction hob.
