Who creates HomDera content
HomDera is an independent, family-run information project based in Ukraine. Our small team is responsible for website development, calculator logic, content preparation, editing, usability checks and ongoing updates.
Dera Builder and Dera Planner are editorial pseudonyms used to distinguish two areas of responsibility within the project. They are not presented as licensed professionals, external reviewers or holders of qualifications that have not been independently verified. The pseudonyms help readers understand whether a note reflects a practical renovation perspective or a planning and usability perspective.

The two editorial roles reflect how work is organised within HomDera. Dera Builder focuses on practical renovation questions, materials and quantities, while Dera Planner focuses on planning, calculator inputs, backup power topics and reader usability. Both roles are part of the same family-run project and do not represent separate external experts.
π¨βπ§ Dera Builder
Editorial focus: practical renovation, material quantities, preparation, project costs and the logical order of work.
Dera Builder explains renovation topics in straightforward language, including what to measure, where a waste allowance is needed and which common mistakes can lead to unnecessary spending.
This editorial role pays particular attention to practical details such as surface preparation, work sequence, quantity checks, manufacturer coverage information and project costs that are easily underestimated.
Topics commonly covered by Dera Builder
| Area | Editorial coverage |
|---|---|
| Renovation | Project stages, preparation, work sequence and common mistakes |
| Materials | Coverage, quantities, waste allowances, product comparisons and practical use |
| Project costs | Budget structure, preliminary estimates, additional expenses and cost control |
| Work sequencing | Preparation stages, dependencies between tasks and situations where professional work should come first |
π©βπ§ Dera Planner
Editorial focus: renovation planning, backup power, checklists, calculation inputs and clear decision-making steps.
Dera Planner turns broad subjects into manageable actions: what to do first, what information to collect and what to check before using a calculator, ordering equipment or speaking with a professional.
This role also reviews whether guides and calculator explanations remain useful to readers who have no previous experience with renovation, batteries, UPS systems, inverters or household energy planning.
Topics commonly covered by Dera Planner
| Area | Editorial coverage |
|---|---|
| Project planning | Checklists, preparation, task order, measurements and decision control |
| Backup power | Batteries, UPS systems, inverters, portable power stations, runtime and essential loads |
| Household energy use | Appliance demand, realistic operating time, system losses and planning priorities |
| Reader experience | Clear wording, article structure, calculator instructions and practical examples |
How we prepare our guides and calculators
- We select topics that can help readers plan a renovation, estimate materials, understand household energy use or compare backup power options.
- We explain technical terms in plain language without presenting general information as personalised professional advice.
- We use manufacturer documentation, recognised formulas and other relevant reference material where the subject requires them.
- As part of our internal editorial process, we check wording, units, assumptions, calculation logic, result labels and consistency between related guides and calculators.
- We identify situations in which manufacturer instructions, an on-site assessment or advice from a qualified professional should take priority over a general online estimate.
- We update affected pages when we identify an error, unclear explanation or inconsistency.
How editorial notes are identified
Some HomDera guides include short editorial notes. These notes highlight a frequent mistake, explain an easily overlooked detail or offer a practical way to approach a decision. They are part of the article rather than testimonials or comments from external specialists.
π¨βπ§ Dera Builder: a practical note about renovation, materials, quantities or project costs.
π©βπ§ Dera Planner: a note about planning, calculation inputs, task order or reader usability.Editorial responsibility and limitations
We aim to publish useful, understandable and appropriately cautious information. However, every home and project is different. Construction type, surface condition, existing services, local requirements, product specifications and installation quality can all affect the correct approach. HomDera should therefore be used as a planning resource rather than a final instruction for complex or safety-critical work.
Results produced by HomDera calculators are preliminary estimates based on the values and assumptions entered by the user. Exact material quantities, project costs, electrical solutions and equipment specifications may require accurate site measurements, manufacturer documentation and an assessment by a qualified professional.
