Basics of interior design

Interior design processes

The interior design process is creative and in many ways unpredictable. To repair the house should be approached very responsibly. Only people with interior design skills should be involved in the repair. Each designer finds its own way of implementation: it acts according to the system, or each time randomly at the behest of the heart client. In this article, we will tell you about the sequence of works in the interior design process.

We divide the process of interior design into the project and post-project parts.

Residential interior designing

1. Interior design terms of reference: survey, measurements, functional zoning, photo fixation.
2. Planning decision.
3. Detailed design: geometry, materials, working with adjacents.
4. Interior design render (3D rendering interior design) and light design.
5. Working documentation.
6. Equipment: lists of materials and equipment.

Stage 1 — terms of reference

The technical task is the first part of the design, in which the client shares their wishes, and the designer gets acquainted with the object.

This is a set of structured information that will be used for designing. Designed in an album, the technical task allows the client to look at all their wishes once again in full and confirm that this is exactly what you need.

The technical task stage consists of:

  • collecting preliminary information;
  • personal data;
  • photo fixations;
  • measurement plan;
  •  selection of references;
  •  functional zoning;
  •  registrations.

1.1. The designer gets acquainted with the object.

It is useful to go to the object. Find out where and how the sun is present, what views open from the Windows and how they can be used in the arrangement of rooms. The designer studies the architectural and stylistic features of the surrounding area. This will help put the project in context, create a strong idea, and link it to the environment.

1.2. The dialogue on the subject.

If the first meeting takes place at the facility, the client tells about their wishes. This is a convenient format for Dating and collecting primary data. You can continue the interview in a working format in a cafe or office.

1.3. Working with the client’s wishes.

The client shows the designer everything that he liked in the journal of interior design, in interior design stock photos and in travel. The designer studies and plans are similar in spirit to ideas in the project. If the client does not have pre-selected materials, the designer will share his interior design proposal.

1.4. Measurements, creating interior design drawings. 

The designer will accurately measure the object and enter data on the interior design drawing: walls, heights, load-bearing structures, openings, binding to communications. The correct measurement technology will save you from design errors and the overspending of materials during construction.

1.5. Photo fixation.

Photos taken with a wide-angle lens will accurately reflect reality. The photos will show walls, Windows, communications, and architectural features that take a long time to draw. Photos will help the designer navigate in space and find possible discrepancies in measurements, and will also be useful for Visualizers and engineers.

1.6. Analysis of engineering networks.

It is important to fix technical details on measurements. The designer measures and binds all cables, pipes, exits, openings, and communications to the drawing, and marks load-bearing structures and walls that can be removed.

1.7. Functional zoning. 

Using functional zoning, you define the required area for each room, and then place the rooms in the space. The designer uses functional zoning in order to discuss with the client options for the location of zones in the space and find the optimal solution.

1.8. Style and home design concepts. 

Based on personal data and collected materials, the designer prepares a concept for the design of the living room, kitchen, dining room, bedroom, guest rooms, and children’s rooms. This makes it possible to determine the colors, materials, content, and atmosphere of the interiors at the stage of the technical task, and to reduce the design time.

The terms of reference reflect everything that the designer managed to discuss with the client at the first stage of communication and research of the object. As a result of all activities, the designer creates an album of technical specifications, which is the starting point for the development of a complete sketch project.

Stage 2-preliminary design

The preliminary design includes:

  • planning decision;
  • geometry sketches;
  • a basic selection of materials, colors, and equipment;
  • visualization;
  • lighting design.

2.1. Planning decision. 

The planning solution is based on a dimensional plan. The designer creates logical solutions to the space that reflect the ideas of the TK or add new findings. It handles space delicately, makes rational use of every inch of space, and places functions planned with the client.

The layout is the skeleton of the project, half of the design. It should be given maximum attention. The result will not disappoint: a well-thought-out planning solution will become the basis for a high-quality project.

2.2. Geometric design. 

The designer develops three-dimensional sketches. Sketches contribute to the development of the idea and make it easier to understand the space. When a client sees interior design drawing, it is easier for them to make a decision and agree on an idea.

The designer can also provide the client with an interior design mock up, where the customer can see the result will be Before and after interior design.

Sketches can be made in the form of drawings, three-dimensional graphics, manual feed, or layouts. There is no color in the sketches because the color initially distracts from the idea and makes it difficult to coordinate.

First, the designer works with the main area: usually, it is a living room-kitchen-dining room. Agrees, and then takes over the rest: bedroom, guest, children’s, bathrooms.

At this stage, you should consider the engineering that affects the design: ventilation and air conditioning. To do this, it is necessary to attract specialists for consultation or to create a complete project.



2.3. Materials, equipment, detailed design, visualization task. 

After approval of the sketches, the designer finalizes the design: selects materials, furniture, accepts schemes from the adjacent elements and takes them into account in the design, creates a task for visualization.

2.4. Interior design rendering (3D rendering interior design) 

Visualization will show the client exactly what the interior will be in life. In the 3D interior design images, the client will see lighting, real finishing materials, matte and glossy surfaces, distribution of reflections, and color design.

Visualization eliminates incorrect decisions, unnecessary costs, and possible disappointments. Common sense will not allow you to start repairs before the client sees the interior in 3D, even if everything seems clear.

The designer visualizes rooms with a design, including bathrooms, and does not visualize utility and technical rooms.

Visualization and light design is the last stage where you can evaluate the entire design and, if necessary, make final adjustments that will be taken into account in the working project.

2.5. Lighting design
Light allows you to highlight the desired accents and literally enliven the space, giving texture and volume to any surfaces. With the help of lighting effects, you can build up to half of the interior design and only with the help of 3D graphics, you can see in advance how the light design will work in the interior.

Stage 3. Working draft

The designer develops a working project based on visualization, taking into account possible adjustments. The working project consists of drawings, linking engineering equipment, furniture, and other equipment.

3.1. The matching of design with engineering solutions

All the projects that were developed during the design process, the designer takes into account in the working documentation: ventilation, air conditioning, smart home, home theater, swimming pool, and other related projects. Everything that has not yet been selected remains in the draft version.

The development of engineering projects is not included in the design project. The designer issues a technical task for the development of engineering projects to specialists. The designer links the finished projects with the working documentation.

3.2. Final selection of finishing materials, furniture, equipment

The sheets display the name and number of ordered items required for the implementation of the object. Picking can even start with a technical task and go through the entire project, but in this section, the album gets a finished look with links to drawings and visualization.

3.3. Working documentation

According to the album of working documentation, the client arranges a tender among construction companies and private teams. Sane builders implement the project without any questions, and inexperienced ones will be easy to expose. A good working project allows you to control the construction process and ask contractors for errors to the fullest extent.

3.4. An album of interior design drawings

1. Measurement plan.
2. The plan of dismantling.
3. Plan for the construction of partitions.
4. The plan of arrangement of furniture and sanitary ware.
5. Floor plan.
6. Ceiling plan.
7. Plan of placement of lamps, light groups, and switches.
8. Plan of sockets, low-current electrical terminals with wall bindings.
9. The basic plan for ventilation and air conditioning.
10. Basic wiring of water supply.
11. Sweep the walls in places necessary for construction.
12. Layout diagram of the matched tile.
13. Explication of premises.
14. Nodes of complex and design solutions.
15. Sketches and dimensions of decorative and architectural elements.
16. Sketch solution of built-in furniture.
17. List of finishing materials with areas and names.
18. Statement of filling in doorways.
19. List of window openings filling.
20. List of furniture items.
21. List of light sources.
22. Specifications and recommendations for decorating floors, walls, ceilings, and another decor.
23. Selection of decoration of window openings.
24. The album with the recommended materials.
25. An album with recommended furniture.

Interior design drawings

3.5. Tasks for the development of individual products

Built-in furniture, curtains, countertops, stone structures, glass objects, aquariums, cinemas, fireplaces, kitchens. Creating Executive drawings of individual structures may be required at the implementation stage. As in the case of engineers, the designer provides sketches, dimensions, materials, important components and basic solutions, and the technologist of the selected contractor creates Executive drawings. These drawings are approved by the contractor with the client or with the designer under the configuration agreement..

The final design of the project
As a result of the design project, the client receives three albums necessary for the implementation of the design:

1. Album of 3D rendering interior design.
2. Selection of materials and equipment.
3. Working drawing.

If necessary, develop projects:

1. Engineering networks and structural changes.
2. Advanced light design.
3. The project of furniture and individual products

At this stage, the design project is completed. On its basis, the contractor calculates the estimate. The designer offers supervision, configuration, construction management or General Contracting-all stages of post-project services.

The main thing to remember is that repairs will breathe new life into your home.

— Can we not make a project, but build it live?

– Measure thrice and cut once.
You can work without a project, but the result will be unpredictable, and there will be zero leverage for contractors.
