When deciding to renovate or finish your apartment, it’s worth remembering that the idea and visualization of the interior are just the beginning. To bring your vision to life as planned, a technical design is essential. This documentation translates aesthetic goals into specific construction solutions. Without it, working with the renovation team can be fraught with misunderstandings and unnecessary costs.
What is a technical design?
A technical interior design is a detailed set of drawings and guidelines that provide a step-by-step guide to completing all finishing work. It includes not only floor plans but also precise information about installations, built-ins, and materials.
Thanks to it, contractors know:
- where to run the electrical and water installations,
- how to plan spot and general lighting,
- where to install sockets, switches and light points,
- how to lay the floor and design the ceiling,
- how to make custom-made furniture or carpentry.
You could say that such a project is an instruction manual for the entire renovation – the more detailed it is, the fewer problems there will be during the implementation stage.
What does interior design include?
The scope of the technical design depends on the design office, but most often it includes:
- functional plans with precise room layout and dimensions,
- electrical installation design – arrangement of sockets, switches, light points and connections for electronics/household appliances,
- lighting design – division into main, zone and decorative lighting,
- water and sewage installation design – location of connections for sinks, toilets, washing machines and dishwashers,
- floor and ceiling designs – drawing divisions, patterns, levels and materials,
- drawings of custom-made furniture – built-in wardrobes, kitchen, TV cabinets, wardrobes,
- detailed technical drawings of carpentry, stonework and glass elements,
- material lists – floors, tiles, paints, fittings, lighting, decorative elements.
Thanks to such documentation, the investor and contractor have a complete guide that minimizes the risk of errors and allows for better cost control.
Why is technical design so important?
Without a technical design, renovation work can lead to a series of surprises. Construction crews often interpret general drawings in their own way, leading to misunderstandings and rework. A well-prepared technical design:
- saves time – contractors work according to the agreements, without unnecessary interruptions,
- reduces costs – precise calculations reduce material consumption and eliminate rework,
- guarantees consistency – each interior element is consistent with the design concept,
- facilitates communication – the designer, investor and construction team use one documentation,
- increases the value of the property – a well-thought-out technical design is a guarantee of quality and durability of the finish.
When is a technical design prepared?
It is created after the design concept is approved. First, the investor selects the functional layout and overall aesthetic, and then the designer prepares documentation that enables the practical implementation of these assumptions.
It’s best to develop a technical design before any construction work begins. This allows you to:
- avoid modifications to installations,
- order materials in advance (e.g. custom-made furniture or unusual elements),
- plan the work schedule and optimize costs.
In the case of larger investments, e.g. apartments in developer standard, the technical design should be ready several months before handing over the keys.
