Building cheaply is no longer so easy these days, because building prices have skyrocketed in the past two years. The most effective way to save money: Think carefully about how much space you really need as a family. Because every square meter costs. With early, well-thought-out planning and a smart choice of materials, you can save even more without sacrificing quality. Our following examples show how to do it.

Build cheaply through clever use of space

Before they started building, the Schieders thought carefully: how they want to live, what is important to them - especially what they do not want. They saw the architect Wolfgang Fischer on TV and thought his compact, ecological houses were great. Already at the first meeting, the builders noticed: "It immediately captures what we want!" He designed a house for four residents (picture above) that only needs 104 square meters. The rooms of the two children and the parents are small, but appear much larger due to the balcony in front and the advantage that the cupboards are operated from the hallway. It fulfills three functions: access to the rooms, a closet - and there is also space for a desk. Space that can be used multiple times saves budget.

Conveniently built with an open floor plan

Narrow, but long and a hidden roof terrace: In this house, the traffic areas are limited to a minimum. This is made possible by an open floor plan. A functional block that accommodates the toilet, kitchen and cloakroom, zones and separates areas. Because the client is skilled in terms of craftsmanship, the architect planned with such building materials and constructions that allow many work to be carried out in-house. The underfloor heating was installed directly in the floor slab, saving the heating screed. Because the builders like the industrial look, they forego expensive floor coverings and elaborate surfaces.

Build cheaply on a remaining plot

In the middle of the village there was still a small remaining plot of land, complicated to build on. Father and son were tempted to design here and prove that a building can be built even on a small budget. They planned two identical houses that blend unobtrusively into the townscape. Slightly located on a slope, they offer a view of the church and the castle ruins. In favor of this view, the principle of the typical single-family house is turned upside down: the kitchen and living area are at the top, with the best view. On the two lower floors there are three neutral rooms and the bathroom. Ideal for young families or couples, because everyone can set up as they please. A tailor-made expansion costs a lot of money.

Inexpensive construction with a reduced traffic area

How many square meters is it good to live in as a family? Architect Joachim Pies and his family answered this question quite clearly: three of us are enough for three of us! With a good room layout this is possible. The house is 12.50 meters long and 4.50 meters wide. There is no wall on the ground floor, the kitchen is exactly in the middle. The living and dining room are located at the end. The upper floor works similarly: rooms for children and parents on the gable side and the bathroom in between. The traffic area was reduced to a minimum and a basement was completely dispensed with - two factors in order to save costs. The entrance area, the room for the building services and the storage room do not have to be heated and were therefore added to the house as extensions made of translucent double-wall sheets. This is also why the actual house with the heated rooms could be built so small.

Like the father, like the son - now they are building houses together and proving that well-planned buildings and low construction costs are not mutually exclusive. Good, cheap and future-proof houses can be built, especially with well thought-out and clever planning, like the house presented above on a hillside on the remaining property. On the other hand, later, on the construction site, hardly any money can be saved - every change becomes more expensive.

How do you manage to build inexpensively?

Especially with a compact, simple building body. Every oriel, offset and lead costs money. Simple houses can be easily realized in prefabricated timber frame construction. Anyone who, as a builder, then uses unconventional building materials that would otherwise be used in industrial construction will be able to build affordable housing.

Can you explain the unconventional materials to us?

We used slate bitumen membranes as roofing and built partitions with translucent polycarbonate multi-skin sheets. This way daylight enters the room from all directions and makes its borders fluid. It may sound strange, but we have covered the steps of the stairs with kitchen worktops: extremely robust and practical because the front edge is already rounded.

What can be saved on the building construction?

On the one hand, we strictly adhered to the optimal wooden construction grid of 62.5 centimeters. And on the other hand dispenses with the installation level. We laid the supply lines for electricity and heating directly in the floor. This simplifies the construction of the outer wall, the construction time is shortened, less material is used - and all this saves money.

Can you tell us where the drainage is hidden?

It was important to us not to weaken the monolithic and symbolic structure with a gutter and downpipes. That is why we have hidden the drainage in a double substructure.

Technical terms on the subject of areas

  • Gross floor area (GFA) outlines the space that is calculated from the external dimensions of a building. It must be determined for each floor.
  • Construction footprint (KGF) defines the footprints of all "rising components". In the case of single-family houses, this primarily includes the unusable space on the walls.
  • Netto-Raumfläche (NRF) sums up the usable floor space of a building. It is subdivided again into: Usable area (NUF) - effective usable base area, technical area (TF) - area that is used to house the building services, traffic area (VF) - which serves to access the rooms and the traffic within buildings (stairs).
  • Living space only refers to areas that actually belong to the apartment. According to the Living Space Ordinance (WoFlV) the following are not included: basement, heating, drying rooms and garages. Balconies, loggias, terraces, winter gardens and rooms with a height of less than two meters are included with only 50 percent or 25 percent of the floor space.

Technical terms on the subject of costs

  • Cost framework: First basic data about what the future house may cost. You have to explore this framework yourself. Serves as the basis for deciding whether you want to build and for the initial financing considerations. This is important in order to give the planner a budget.
  • Cost estimate: Based on the desired standard and on the basis of cost parameters, the architect targets the costs according to service phase 2 (preliminary planning) of the HOAI fee schedule. The costs can deviate up to 30 percent later.
  • Cost calculation: based on the draft drawings worked through and the mass calculations: service phase 3 (draft planning). Here is already calculated in more detail. Because there is more information about construction and technical expansion. The deviation may still be 20 percent.
  • Estimate: The estimate (or estimate) is based on the final, because complete execution, detail and construction planning. For example, calculations on stability proof, thermal insulation, sound insulation and building services, as well as the performance descriptions (tender) are to be included. In addition, the cost estimate is based on the offers put together by the construction companies. A deviation of up to ten percent is allowed.

Build cheaply: Where can you save?

  • Basement: An often hotly debated topic: Do we build with or without a basement? Yes, it costs a lot, especially if it has to be designed as a white tub (against pressurized water). Where the land price is extremely expensive, it makes no sense to forego the additional space. Otherwise, rooms for home automation and storage rooms must be housed on the ground floor or on the upper floor. That also costs money, but is usually cheaper than digging and concreting in the ground.
  • Carport or garage: If you want to save additional money when building, you should better choose a carport. This canopy can be up to five times cheaper than a garage. If you still don't want to do without a garage, you can do it yourself and cut costs.
  • Bathroom: The smallest room in the house costs the most. Do you really need an extra bathroom for the kids? How about separating the toilet from the bathroom? Can a shower be installed in the guest toilet? So you can equalize the confined situation (especially during puberty) with little effort. If you want to build two bathrooms, it would be good to place them one above the other or to plan them in the floor plan so that the building services can be operated from a continuous installation shaft. This simplifies the work for the plumber and saves additional meters of pipe.
  • Windows: Limit yourself to a few, but the same formats. Because if every window has different dimensions, each one is made individually. This takes longer because the carpenter has to reset the machines more often, and extends the working time - and that costs money.
  • Equipment: Some builders always choose the most expensive material or product unerringly. Ask yourself the question: What does this mean for the quality of living? Are the additional costs worth it, or do we achieve the same atmosphere with a simpler product? There are sometimes considerable price differences between different versions from simple to luxury. Instead of plank parquet, chopsticks parquet also does - or you simply grind the screed and do without the tiles.
