The entrance doors to the apartments are security ones (Safety Class RC3), fitted with a panoramic peephole. Fittings are also of a security type, outside the door there is a doorknob, inside a handle. The threshold is in the face with a tread terrazzo layer from the corridor. The doors are fireproof.
The interior doors are lacquered with a lining and hidden hinges. The doors are fitted with an M&T forging. The doors are opened primarily into the room, in the direction of entry. According to the character of the connecting room, the doors are full or glazed.
Insulating triple glazing with aluminium profiles of anthracite colour with interrupted thermal bridges. On the side of the balconies, terraces and enclosed balconies (loggias) there are large-format French windows and doors that are horizontally sliding / folding or opening / folding. The glazing is transparent. The height of the windows from the side of the room is the height of the fixed part of the window frame.
Balconies and loggias
The lower part of the sill is full, the upper part is completed with safety laminated glass with a finish in the form of a stainless steel profile. In case of the loggias, the drainage is executed under the tread layers after the laid insulation stack, while the balconies are connected to the vertical hidden drains in front of the facade. From the inside, the balcony sills are made from alucobond, from the outside they are stone.
From the interiors, the top part of the sills is tiled with a white wooden sill board. On the outside there is a stone slab.
The roller blinds are exterior and on selected windows (southwest-, southeast- and northwest-facing facades). In the folded state they are integrated under the facade tiling. The shading is controlled electrically. The roller blinds can also be centrally pulled up using a common control switch in a room in the apartment. The control buttons are arranged according to a specific layout, primarily together with the lighting control at the entrance to the room.
Gypsum plasters or screeds will be in all the living rooms, kitchens and entrance vestibules (hallways). The bathrooms and lavatories will be equipped with a large-format lining of the Melt naturale series, manufactured by Iris, up to the ceiling. The colour options are: (1) Ivory, (2) Greige, (3) Grey, (4) Umber.
The living rooms, including the kitchenette and the entrance vestibule (hallway), will feature a wooden glued multilayer floor. The skirting slats will be white. Large-format ceramic floor tiles of the Melt naturale series, manufactured by Iris, will be laid in the bathrooms, lavatories and chambers. The colour options are: (1) Ivory, (2) Greige, (3) Grey, (4) Umber. In the entrance door from the corridor, the terrazzo threshold will be executed within the terrazzo floor layer of the adjoining corridor. The balconies, loggias and terraces will be fitted with wooden decks of tropical wood.
The bathrooms will be fitted with Villeroy & Boch, Kaldewei and Hüppe premium furnishings. The toilets will be hung, the tanks integrated into the walls under the tiling with a two-push mechanical flushing control. The bidets are hanging too. The washbasins are embedded under the washbasin board of the Living series by Querella, the colour options of which are: (1) Basaltina, (2) Navona. The Kaldewei bath is steel and enamelled. The corner showers have a stainless-steel drain channel and a full-glass shower enclosure without a frame. The faucets for the washbasins and bidets will be of a standing and lever type. The shower corners will be fitted with a concealed thermostatic tap. All the water taps are of the HANSGROHE brand. The bathrooms will also feature Zehnder design ladders.
Each apartment is connected to a residential distributor and collector (“R+S” in Czech), which is located in the common corridor. The measurement of heat consumption and the apartment control are situated on the R+S. The heat distributors are conducted in the floors. In the rooms where there are the window sills, steel plate radiators with a smooth face area are fitted. The connection of the body to the floor heating distribution is executed in a concealed manner. The body is equipped with a thermostatic head. In the living rooms with large-format French windows or with balcony doors, floor convectors (without a fan) with a floor grille are fitted. The convectors are controlled by thermostatic valves which are again controlled by a room thermostat. In the bathrooms there are Zehnder heating ladders with an electrical cartridge. The bathrooms are also fitted with electric floor heating.
Ventilation and recuperation
The apartments will be equipped with ventilation with a forced intake of fresh, filtered and heat-treated air with a forced exhaust of exhaled air through a central heat recovery unit. The central unit will be located on the roof of the building. The supply of fresh air will be carried out in the corridor of the apartment, where the ceiling will be lowered and where the air will be pushed through the grid into the living rooms. It will be exhausted from the bathrooms and lavatories via a variable air-flow controller through
a duct back to the unit on the roof.
The HVAC (heating, ventilation and air conditioning) will be controlled by local controllers with a weekly program, allowing for an individual adjustment of ventilation intensity over time and in the individual apartments. The variable air-flow regulators will be controlled in each apartment together, so that the ventilation could be in the so-called equal pressure. In the bathrooms and lavatories there will be a button; when it is pushed, the air flow will be increased for an adjustable period of 3-20 minutes.
For the installation of the kitchen extractor hood, a draft will be prepared in the shaft, which will end in the kitchen area on the face of the shaft (5 cm below the ceiling plate) and will be fitted with a self-closing flap with a magnetic locking in the closed position. The pipeline will be rated at a flow rate of 300m3/h on the kitchen extractor hood.
All the living rooms at the Churchill Residence will be equipped with cooling through internal wall circulation units. The apartments on the top floor will be cooled by a multi-split system, for each apartment separate, connected from an apartment switchboard. The cooling units will be controlled by a remote infrared controller. The apartments on the other floors are cooled by VRV systems and a mini VRF system (these are outdoor units for more apartments). The indoor units will also be operated by an infrared controller.
The cooling system of all the apartment VRV systems is equipped with a control system, whose control and display element is located in the reception area. This element allows for the budgeting of the electricity consumption for cooling for the individual apartments. The outdoor condensing units and the indoor refrigeration units in the apartments will be connected from a separate measuring circuit. The M&R system (i.e. the control system) will carry out the preparation (cables to the indoor units) for the potential connection of the cooling system to the central apartment M&R system. If required, the indoor units can be equipped with cards – a communication interface that will be connected to the prepared cables.
Electrical installation – heavy current
The electrical installations are designed with a preparation for the intelligent (smart) apartment control. In the kitchen, the connection will be terminated by terminals in the corner at the planned position of the kitchen. The standard includes the lighting of balconies, terraces, bathrooms, lavatories and corridors. The lighting fixtures of the living rooms, kitchens and kitchenettes are not fitted and outlets according to the project will be prepared for them.
The direct billing (invoicing) measurement of the individual apartments is in the technical room on the ground floor (the VRV units will be measured on the distribution network for the common areas and disbursed). In the event of a distribution network failure, the supply of electricity is not ensured. The apartment switchboard will be integrated, together with the M&R and low-voltage distributor, in the plasterboard box in the area of the potential cabinet (3 x 25A fuse, maximum current power 11 kW). All the wiring is in copper.
According to the project, the rooms in the apartments are equipped with heavy-current sockets. In the gardens and on the terraces the lighting of the gardens will be prepared (an outlet to the electric box).
Electrical installation – low current
Within each apartment, a low-voltage apartment distribution unit will be installed in the entrance corridor (hallway) of the apartment, from which the apartment wiring will be connected according to the project. There will be one TV socket in each living room. The system will be complemented by a central satellite dish for satellite reception. The apartments will be equipped with a videophone, having a 7” touch-sensitive colour display, which will be located in the entrance corridor (hallway) of the apartment. The home bell will be autonomous and connected directly to the home videophone.
Planting and irrigation
The front gardens of the apartments will be grassed in standard, in case of some apartments partly with a pebble surface. On the first underground floor, the walls around the perimeter will feature climbing greenery, between the gardens and a gabion wall there will be baskets intended for climbing greenery. The private gardens are enclosed by a wall, completed with a design bar grille to a minimum height of 1.6 m above the adjacent external terrain. The mutual separation of the private gardens is executed by an empty gabion wall, intended for planting climbing greenery.
Reinforced-concrete monolithic construction
The roof is single-layer, flat, vapour-proof and with insulating layers. The thermal insulation is made of mineral wool slabs.
Large-format natural stone plates with thermal insulation, made of mineral fibres.
The walls between the apartments are brick, made from reinforced concrete, with additional masonry. The internal partitions are also bricked, in some places made from reinforced concrete with additional masonry. The installation panels are made of plasterboard.
The ceilings are from reinforced concrete, with gypsum plaster or screed on the facing side. In the bathrooms and lavatories there are plasterboard ceilings, in the place of the distribution of air conditioning there is acoustic insulation. On the ceilings at the balconies there is a smoothing plaster on a suspended ceiling.
Surface of the walls - common areas
The walls in the entrance hall, in the adjacent corridor (the 1st above-ground floor), on the main landings on all the above-ground floors and on the 1st floor near the 3rd section and on the elevator platforms and their hallways in the basement will be fitted with large-format ceramic panelling. The escape routes (corridors) on the 1st floor, the baby carriage room and the technical rooms on the 1st floor will be painted with an abrasion-resistant painting. The cleaning chamber in the basement will feature walls made of ceramic tiles. The other walls in the basement are made from reinforced concrete with an abrasion-resistant, air-permeable painting. The interiors of the cellars will have walls made of unfinished concrete blocks with a hydrophobic coating. On the 1st underground floor, the reinforced-concrete walls and pillars above the level of 2.1 m will be covered with mineral slabs. The edges of the walls and columns in the garages will be marked with an alert yellow and black hatching.
Floors - common areas
The entrances to the building will include a cleaning zone. The floors of the entrances and common areas, corridors, escape routes (corridors), elevator platforms, stairwells and landings will be made of cast terrazzo. The area of the reception desk will be equipped with ceramic tiles. The floors in the garages, the ramps and the floors of the technical rooms in the basement will be made from concrete with a water-resistant and oil-resistant screed. The floor in front of the staircases (in the parking lot) will be differentiated by a coloured paint.
Doors to the building
The doors to the building have aluminium profiles and safety glazing. They are equipped with a security lock with an electronically controlled entry (a magnetic card or a chip).
The garage has a rolling shutter gate with a grille and an electric drive. The gate is controlled by access readers and it is equipped with the optical signalling of opening / closing.
The main entrances, the entrance for cars and the entrances from the stairway are monitored by an electronic access control (card readers). The access system has its own backup, therefore it will run even in the event of a power failure. The main entrance to the building is equipped with a videophone and a bell table. Videophones are also available at the car entrance and exit. The elevators are equipped with an Intercom. The car entrance gate will close immediately behind each vehicle. Inside, behind the gate, there will be barriers for both directions. In the entrance pillar there is a roller table with a camera for the communication with the reception and with the apartments (remote opening of the barriers and gate from the reception). The opening at the car entrance is done by an active card used in the rest of the building too. The safety of residents will also be taken care about by the camera system, which is designed for the entrances and common areas (except for the platforms of the elevators), reception, hallways of the basement, parking area, car entrance / exit and passage. The cameras will also monitor the pavements around the building, but in such a way that the gardens of the apartments would not be monitored. The common areas also have an overall protection, which is connected to the central facility protection desk with the signalling to the reception.
The apartments feature safety doors with fire protection. Electronic Fire Alarm (“EPS” in Czech) controls fire dampers, closes fire shutters in the garages and the ventilation in the staircases and it announces fire alarms. The transmission of the signal to the Central Fire Protection Desk of the Fire Brigade (“CPPO HZS” in Czech) is immediate at night; during the day after the alarm has been acknowledged or after the system time has elapsed. When the alarm is announced, the HVAC (heating, ventilation and air conditioning) switches off, all the elevators go down to the nearest station, the locks on the escape routes (corridors) are unblocked and the key safe is unlocked. In the car parking CO detection, dry sprinklers and fire roller shutters between the fire protection sections of the parking place are installed. The emergency lighting of the corridors, staircases and garages will be fitted with a built-in, maintenance-free battery and it will perform the function of emergency lighting (escape, escape routes). Specified fire safety devices feature a secured supply with a replacement power supply – using a UPS (uninterruptible power supply).
There are three personal elevators in the building. The elevators feature a large-format mirror, premium ceramic tiling and ceiling lighting. These elevators are not of an evacuation type. The reinforced-concrete shafts are resiliently separated from other load-bearing structures.
Planting and irrigation
Climbing greenery will be planted on the outside of the supporting walls. The common greenery will be irrigated automatically. In the private gardens the following preparation is planned: a small ground shaft in which there will be a valve for the connection of own automatic irrigation, managed by the owner. The electrical preparation in the small ground shaft is designed only for the need of automatic irrigation and it is in low voltage (24V).
Control of the lighting of the building
The lighting of the corridors, routes and garages is controlled by motion sensors. The control of the lighting of the cellars will be switched by sections, and these will be controlled by switches placed near the entrances. The control of other rooms (the facilities of the basement) will be executed locally by switches at the entrance to the room.
Lighting of the area
The pavements and passage of the building are illuminated by lighting fixtures that will be switched automatically. The circuit in the passage will be illuminated less intensely in the night, the rest of the circuits, which are lit only in the evening, will switch off automatically in the night so as not to disturb the residents of the building. The walls will only be lit in the evening, not in the night. The entrances will be illuminated with automatic switching. In some places, powerful reflective lamps will be fitted in order to scare off dogs.
