An interstory staircase for a private house — instructions on how to make with your own hands (105 photos of new designs)

In the construction of a country house, an inter-storey staircase has become a necessary element and part of the interior. It can be both inconspicuous and perform decorative functions, be the center of a design composition that affects the design of the premises of the whole house.

When it is made, assembled with your own hands, an accurate calculation of all its parameters is necessary so that it does not become traumatic.  Many companies are engaged in the supply of components, from which, according to the instructions, you can assemble a ready-made structure, not make its elements yourself.

Its parameters and device features need to be known in order to choose the right staircase that will fit perfectly into the interior of the house.

You can design the structure yourself, make a sketch of it, or pick up an existing version in the photo catalog.

The components of the stairs can be important, used without fail, and additional, included in the device of certain models. Steps (vertical, horizontal part), supports for their support are the main elements of the structure.

Support beams are of the following types:

  • To support the steps from their end part (called a bowstring);
  • With an emphasis on the bottom (sideways).

In some types of stairs, you can find the absence of railings and balusters – important elements in some structures that enclose the space, protecting from falling. Other models have racks and fasteners on special bolts.


The interstory stairs used in private houses can be divided into the following types:

  • Marching;
  • Stairs with special bolts in the design as a fastening element — bolts;
  • Screw.

A private house of any type is most often equipped with a flight of stairs. In the design, it has marches consisting of several steps, separated by platforms. It is convenient to climb up and down it, but it usually takes up a lot of space. As a fastening of the steps, kosours or a bowstring are used.

Marching stairs , in turn , are divided into:

  • Closed and open type (the presence or absence of risers in the design is their difference);
  • Rotary (instead of platforms, run-up steps are used);
  • Quarter-turn configuration;
  • Half - turn type;
  • Circular shape.

The staircase on boltsy has special fasteners in its design – pins with threaded threads, with which the structural elements are connected to each other, attached to the wall. There are no risers, thanks to which the staircase acquires an unusual airy appearance. It can be both compact and stretched. It is characterized by reliability, durability.

The calculation of its technical parameters is quite complicated for self-production.  But – it can be made to order, or purchased disassembled, taking into account the necessary dimensions.

Installation will also cause some difficulties, it is better to entrust it to professionals. It does not hurt to have a preliminary consultation before purchasing components for a staircase of this type.

When the room has a small area, an inter-storey spiral staircase fits perfectly, aesthetically into the interior. Oversized items, furniture will be inconvenient to carry, but a huge plus is saving space, negates this drawback. It is quite available for self-assembly with the ability to work with wood, metal structures.

For a private house, a model with wedge–shaped steps and a rack mounted on one side into the floor, the other into the inter-ceiling is suitable.

Steps in the form of a spiral are fixed to the rack in a circle. And the narrower the interstory opening, the design will be steeper, less convenient. If assembled incorrectly, it can become very traumatic.

Security requirements

When starting to assemble the stairs, you need to pay attention to the following points:

  • The need to install a protective fence when the staircase is in the center of the room does not fit into the walls;
  • The width of the steps should be at least 200 mm, their outer coating should not be slippery;
  • The whole structure can withstand, according to the requirements for residential buildings, at least 300 kg/m2;
  • Reliability, rigidity of the interstory fastening;
  • A ladder with a lifting angle exceeding 45 degrees is not installed;
  • The optimal span width is up to one and a half meters;
  • When the structure is separated by platforms, it becomes less traumatic;
  • Do not skimp on the fastening material, it must be of high quality;
  • All elements of the stairs, manufactured independently, must correspond to the dimensions according to the drawing.


Metal, wood, concrete are used in the manufacture of stairs. It all depends on the type, design, personal preferences.

But – first, a drawing of the future project is made, the location of the inter-storey staircase is determined, a number of issues are solved:

  • Will it be at the junction of the walls or in the center of the room?
  • Is the flooring suitable for these purposes?
  • Will it withstand the load of the entire structure during use?
  • What is the size and type of the future staircase?
  • From what material (wood, metal, a combination of them) will the structure be assembled?
  • Are you planning to purchase a complete set of parts for assembly (ready-made project) or can they be made independently?

During the design process, you will have to consider many options, choose the most optimal one. You can, if you have experience, draw up diagrams and drawings yourself.

It is optimal to contact professional architects, designers and a photo catalog, or in the process of working together to determine the final type of the interstory staircase.

It is best to do this at the construction stage of the house, and not when it has already been rebuilt, in order to take into account all the nuances in the process of installing an inter-storey staircase.

Manufacturing process

Most often, to ensure the best rigidity of the structure, a metal frame is used, which is subsequently sheathed with wood, sheet steel, marble slabs, and other materials to give an aesthetic appearance.

Fittings, corners, channels are actively used for the manufacture of the main elements of the stairs. All parts are connected to each other during welding. The resulting structure is primed, varnished to protect against corrosion.

The platform with all overlappings on which the flight of stairs will be placed is preliminarily strengthened, optimal support points are selected. Structures with optimal weight (wooden or metal) are also selected.

Detailed instructions for the manufacture of an interstory staircase may look like this:

The site is selected, the type of future construction is determined. All technical parameters are calculated, the amount of material (in other words, an estimate is made). Everything necessary is purchased, the details are adjusted to the desired dimensions independently or with the help of professionals.

Beams, bowstrings, scythes are being prepared, steps and risers are being marked. They proceed to the installation of the marches, attaching the risers to them, the steps themselves, striving to perfectly combine the parts without gaps. An intermediate platform separating the marches is being made.

To secure the march from below, at the base, a supporting cross beam is used, anchors and bolts are used from above, to the interstory floor. Fences are mounted with the reinforcement of balusters and intermediate posts using metal studs.

With the help of anchors, the extreme pillars are installed (rigidly attached to the wall). Railings are being installed. Decorative works are carried out (varnishing, using wooden carvings, various overlays).

Of course, the manufacturing instructions are far from exhaustive. But she answers the main questions – "How to start making an interstory staircase. In what order, what to do?"  The rest of the nuances are clarified in the course of work.

In the end, it is not so difficult to make an interstory staircase in a private house with your own hands if you have experience, appropriate material, equipment. You can, of course, buy a ready-made project. But home craftsmen are not looking for simple solutions and easily cope with the tasks.
