Cottage project with garage and workshop and a spacious mansard floor on which the layout four bedrooms and a bathroom

The project of a rational frame house with an attached garage for a large family. The dimensions of the house are 12.7 x 9.7 m. If necessary, the house can be built in stages, since the ground floor has everything you need for a convenient and comfortable stay. The first floor consists of two living rooms with an area of ​​14 and 19 m2, a kitchen of 14.6 m2, a bathroom of 5.4 m2, a wardrobe and an entrance hall. From the kitchen there is access to the terrace. In the living room there is a staircase to the second floor. A garage and utility room are attached to the left wall. The total area of ​​residential premises on the ground floor (excluding the garage) is 69 m2.

The garage is large, measuring 7 x 3.5 m. The garage and pantry area is 31.6 m2. The total area of ​​the first floor is 100.55 m2. The second floor of this frame house is the attic. Under the roof there are four bedrooms ranging from 13 to 15 m2 and a bathroom with a toilet and a shower. The area of ​​the bathroom is 4.4 m2. The total area of ​​the attic is 70.8 m2.

For a relative mark of 0.000, the level of the clean floor of the first floor is taken. Foundations are designed for normal conditions. It is assumed that the base soil is homogeneous, dry, not subsiding. Strong soil not less than 2.0 kg / cm2. Before starting construction on a new site, it is advisable to adjust the construction of the foundations according to the results of geological surveys at the construction site. For what it is necessary you can read on the website in the article "Attention - the foundations of the house", which is located in the "Construction" section. Horizontal waterproofing under the walls is made of surfaced euroroofing material.

The base is columnar. The pillars of the foundation are designed from monolithic concrete of grade B 15. On top of the pillars is a monolithic reinforced concrete beam on which frame elements are supported. Threaded rods ∅20-25mm in increments of 1 meter are provided for strapping fastenings around the perimeter of the rand beam during concreting. Between the rand beam and the ground leave an air gap of 50 mm in order to prevent the deformation of the foundations during frost heaving of the ground. Waterproofing under the elements of a wooden frame is made of surfaced euroroofing material "spolimod". Along the perimeter of the house, make a blind area 1.5 m wide.

It is envisaged that the floor in the garage must be done with a slope towards the gate to drain water. Attention, in the event that the foundations of bulk soils are revealed at a depth of laying, they should be selected and replaced with sand laid with a layer-by-layer seal. The external walls of the house are based on a wooden frame. The distance between the uprights of the frame is not more than 590 mm, when using plates with a width of 600 mm. When using plates of a different size, the distance between the racks must be adjusted. Cut minvata to perform 0.5-1 cm more between the distance between the steakma of the frame and the floor beams. Lay the mineral wool without cracks.

Between the racks of the frame lay basalt cotton wool in slabs of the "Rockmin" type. Overlapping the ground floor on wooden beams. Between the beams, lay mineral wool as sound insulation. Sheathe the surface of the outer walls and the attic ceiling (before installing drywall constructions) with plastic wrap. Seal the joints of the film - glue with tape. Facing the inner surface of the walls and partitions with drywall. The floor of the first floor is made of wooden beams. Insulate the floor with mineral wool 200 mm.

Connect the joists to the frame using M12 bolts. Between the beams, be sure to put spacers from 50x150 boards. For the construction of the frame and roof elements, use dry softwood timber of 1 or 2 grades with a moisture content of 16-20%. Before use, treat wooden elements with an antiseptic and a flame retardant. In the case of installing a gas boiler with a chimney, place the wooden elements at a distance of at least 380 mm from the inner surface of the smoke channel.

The roof is gable. To cover the roof, use a metal tile on a wooden lath with a fireproof coating. In the case of using bituminous tiles, rafters must be covered with OSB tiles. When insulating the roof, use mineral wool in slabs with a density of 30 kg / m3. Minvata lay between the rafters. Under the rafters, from the side of the room, additionally lay a horizontal layer of mineral wool. The total thickness of the insulation for the roof and attic is 350 mm. In order to avoid blowing out the insulation, from the side of the roof, cover with a windproof film, which is able to let out water vapor. Provide an air space of at least 50 mm between the windproof film and the roof.

For heating and hot water supply of a frame house with a garage, use an electric boiler and a boiler or a 24 kW double-circuit wall-mounted gas boiler, which is located on the vestibule wall, or in the kitchen. Connect the chimney to the chimney and bring it to the roof. In the room in which the boiler is located, arrange a ventilation channel ∅130mm, which is brought to the roof. Ventilation from the kitchen and bathrooms - natural with the use of ventilation ducts, which are displayed on the roof. Remove the pipe for ventilation ducts above the roof.

For water supply at home, you can use an external water supply network, a well or a well. To prevent freezing, a water pipe should be introduced into the house under the foundation at a depth of not less than 1.8 m. Sewerage - with the help of local treatment facilities, consisting of a reinforced concrete or plastic septic tank and filter wells. Gravity drainage network made of polyethylene pipes. The depth of the sewer pipes is 0.9 m. The places of the inputs and outputs of utilities should be determined according to the conditions and location of the house on the plot. Power supply of the house from external networks.

The simplest option for external decoration of the external walls of this frame house with a garage is plastic siding. If you need a frame house project with a garage, pay attention to the Kupava project. This project can be viewed here.
