Extension of our craftsmen: an interesting experience

Selection of completed and are in the process of implementing extensions

Annex - concept wide enough and may imply both a small bedroom, and almost a second home on two floors. The need for such reconstruction usually occurs homes with experience, either due to lack of usable floor space, either because of dilapidation of existing terraces and similar structures. They are easier to tear down and build a new capital facilities that could be used year-round. Regardless of the reasons that prompted the roll up our sleeves and go for drastic changes in the construction of extensions has to solve the same problem. Summary - properly attached to the house structure. Consider the options available and examples of participants in the construction of our portal.

Methods of joining extensions

It is believed that there are no problems with the extension will not occur if the foundation under it poured simultaneously with the main, however, this is not quite true.

... - Even if the foundation under the annexe founded originally under the weight of the bulk of home construction sits, and a stress-free foundation - not. Here it is necessary to look at how the foundation carries the load, he suffered (not cracked his or violated ".000") operating the process ...

What we talk about situations where the annexe was not planned - because of the shrinkage difference between the home and more easy, especially unheated design to the choice of the type of connection should be approached as much as possible responsibly. There are two options:

• expansion joint - relevant for monolithic or strip foundations; in close proximity to the main base is cast through an additional seam thickness of 2-5 cm. Before assembling formwork seam often just fill the plates of extruded polystyrene foam. If during the operation will be the base of progress, it will not affect the integrity of the house and outbuildings.

• rigid coupling - roughly speaking, the "sauce" of the same foundation to the existing, fixing by means of valves, clogged the holes drilled in the main base. Feasible only with an established foundation, when the parameters of the extension coincide with the parameters of the house.

Slab and strip foundations poured for an extension of the masonry materials typically blocks, rarely, brick. If the design is facilitated, or framing of beams are often used pillars or piles and problems with joining the foundation does not occur as such. Of course, when all the loads accurately calculated, and the possibility of progress is taken into account and offset by "sliding" the compounds in the walls and roof system.

When extension begins with documents - the history of resideent

Private house, it is not always owned by one owner, it can be initially and proportion.

I want to share the experience of building an extension to the house for several families. There is a house for four families, each with its own isolated section with main walls and outputs on your own site. Brick house to house everyone was added Panelboard veranda, kept in this veranda original form only for me, the neighbors have long been demolished and they have expanded their space with new extensions.

Dilapidated porch carrying construction age is closer to the turn forty years become a weighty argument in favor of demolition and construction in its place of a new extension of the capital. The first step in this direction was the settlement of all legal matters.

• According to the agreement between the parties drew up a section on the home side, but did not share.
• I took a written permission for the reconstruction of their neighbors, in order to avoid possible complications in the future.
• During the year, without haste received permission (approval) for reconstruction in architecture just request the consent of the neighbors.

And with the approval of local authorities with a clear conscience began to build an extension.

Foundation - insulated monolithic plate (Epps, 150 mm) to the backbone of the water floor heating. Adhesion to main foundation plate (MZFL) through the expansion joint. As filling and simultaneously the permanent shuttering - Epps, 50 mm thick. Before pouring laid drainage pipe on the outside of the house and storm sewer pipe with inlets.

Walls - the main structural material aerocrete, 300 mm thick, with an eye on insulation and ventilated facade. Septum and future cool balcony - 200 mm thick block.

Roof - pent. Overlap: wooden beams 100 × 200 mm journalled at three points; rafters 50 × 200 mm; roofing, soft tile (s ventzazorom membrane and for the possibility of further thermal insulation).

The construction was gone a month, the budget amounted to 900 thousand rubles, while the total area of ​​extension of 50 m² (based on the porch).

In the winter extension left with a tight loop (windows, doors) and a working heating - floor heating, plus two panel radiators.

Zero temperature in the room allowed to proceed to the interior decoration. The first winter of the structure survived without cracking and other problems, the second came in a state of readiness of the first, settles floors and insulated attic.

An extension to the log cabins - the history of DimonGrivin

As the saying goes: a long time or a short, but the house is like a home, and requires continued. Therefore, the start frame construction extension is given in which will be placed WC and a small entrance tambour. Now the rub is how to link extension and the main frame according to the rules. This question was asked back in the process of construction, formuchanam asking questions, by the way - a huge thank you to all who responded.

the following plan:

• Melkozaglublennaya tape, but an inverted "U", and under the entire perimeter.
• Extension of the technology for framing boards 50 × 150 mm.

Foundation - as planned, filled tape, having got a pre mortgage drain. The method bases original compound was prepared - and not through the expansion joint and not a rigid coupling, but something in between.

DimonGrivin

Regarding the extension initially I made a mistake in laying the foundation, since before construction had not the slightest clue what to build. It was necessary to lay the foundation for the whole of construction IMMEDIATELY! But what we have, then we have. The main challenge now - to minimize the movement of the extension and the main carcass in relation to each other. I was in some way fortunate, because the foundation I have a few old-fashioned, namely concrete pillars on a sand cushion, and it so happened that future tape at the junction of the bases rests on the pillars (not know whether clear explained) and thereby connected to the main foundation. So I think, maybe a kind of solidity is.

But the very concept of construction has changed dramatically - the year that has passed since the foundation of the fill (to withstand without damage), decided to stay on the walls of aerocrete. Since the annex is planned boiler and heating solid fuel boiler, decided not to risk and lower the level of fire risk. Well, "none of my arguments have failed to convince my husband to frame extension and now we build differently."

Walls - tape waterproofed roofing material to the floor level and in the house and the building was the same, the plinth for the installation of floor beams brought brick. Window lintel cast concrete, since the openings are wide enough, the doorway reinforced metal corners, filled Laying nets.

Roof - rafters of a board 50 × 200 mm, a wall mount hole for carcass and leveling possible movements due to the absence of rigid fixing rafter to annexe.

DimonGrivin

The method used a common interface - skolzyachka. To end the log wall beams nailed, 50-50 m, in the groove under gazosilikata sawed lumber and thus turned sliding mechanism.

Life is different - building stretched over time, but the process is moving.

Details and continued - in the subject line.

The original solution to the issue of expansion - tuning goes under the house with stas_ssp

Almost in real time, you can watch an interesting experiment, which is similar to the forum did not exist.

There is a one-storey frame and modular house, an area of ​​72 m². Our family grew, and it became a place not to be missed. It was decided to increase the size but not the superstructure of the upper floors, and vice versa - an extension of the ground floor with the rise of the house to the desired height of the extension. T. in. The house stands on the pile foundation, it was decided to dismantle the base and dig a pit for the device monolithic slabs. And further on this slab prop up jacks to lift the house.

All participants of the discussion of Default to the solution of housing problem become interested original approach, agreed that "the task interesting." The main problem - not destroy the house in the process of recovery, so how to turn a house "in a pile of firewood," maybe even a strong gust of wind. But the eyes are afraid, and hands - do.

Foundation - in addition to the insulated monolithic slab is insulated the blind area and plinth wall, so that problems with piles concreted into it no problem. The load from the modular floor on the stove will pass the walls of lightweight aggregate concrete blocks.

Walls - deduced several rows under the bearing walls, the house jacking, displayed next few rows, jacking house and so on until the finish. At the moment, "the process has begun."

From the plate level house is raised by about a meter, all cut pile, began laying the first rows. Put the three lines, set the jacks, gently lift the house, under the floor joists lay out "columns" of the blocks. For the insurance of care with jacks and skewed thinking mounted on the corners of the strut-braces. Already have an experience when th deviated from the design of the axes are now vertical lift - the main cause for concern.

As of the 26 of this month, it looks like a construction site.

Pro, included in the discussion, oriented on terms of lifting-building about fifteen days, during normal brigade in number four. So find out what the outcome of the most important stage of this extraordinary renovation, it will be possible in the foreseeable future. The theme is called - "The rise of the house at 3 meters and the construction of a new floor at the level of 0.000».

Output

As can be seen from the examples, the construction of the extension - this is not only quite complicated, but by no means a cheap process, especially if you involve artists. Before its onset, should carefully weigh the "pros" and "cons", and make sure that it is the reconstruction will be justified. After all:

... - Construction of capital added in some cases can be more expensive than the same additional area to implement in a separate building.

Of course, provided that it is technically possible to build a close and not be attached to the house. If the extension, the best option - all will turn out, even when the entity's own equity and the house will have to raise.

On the topic can be found on experience in the construction and design of the original porch, and about turning the house into a stylish cabinsThanks to a solid annexe. In the video - the reconstruction of a frame house.
