About HomDera

About HomDera

HomDera is an independent, family-run information project created in Ukraine. We develop practical guides and online calculators for people planning home renovation, material purchases, household budgets, electrical loads and backup power.

The project was created to make early home planning easier to understand. Our content helps readers identify what should be measured, which costs may be overlooked, how calculator results should be interpreted and when a decision should be confirmed by a qualified professional.

HomDera is developed and maintained by a small family team. You can learn more about the people behind the project, their responsibilities and the way content is reviewed on our Authors page.

Who HomDera is for

• Homeowners and apartment residents planning a renovation or home improvement project.
• People without construction experience who want to understand the main stages of the work.
• DIY planners who need an initial estimate of area, materials, waste allowance or project costs.
• Property owners, small renovation teams and contractors who want a quick preliminary cross-check during early planning.
• Households comparing batteries, UPS systems, inverters and other options for temporary backup power.

What you can find on HomDera

HomDera combines two main types of content: practical guides and interactive calculators. The guides explain project stages, common mistakes, material choices and technical considerations. The calculators turn measurements and product information into preliminary figures that can support planning, comparison and further research.

The main areas covered by HomDera

Online calculators: tools for estimating room areas, material quantities, project costs, electrical loads and battery runtime.

Renovation planning: guidance on project stages, preparation, budgeting, contractor estimates and common mistakes.

Materials: practical information about flooring, tile, paint, wallpaper, pack coverage, cutting and waste allowance.

Electrical planning: accessible explanations of household loads, current, outlets, circuits and the importance of safe installation.

Backup power: guidance on batteries, UPS systems, inverters, portable power stations and realistic operating time during an outage.

How to use HomDera calculators responsibly

Use measurements taken from the actual room, property or product wherever possible.

Check the selected units and compare calculated quantities with the coverage shown by the manufacturer.

Include an appropriate allowance for cutting, breakage, pattern matching or other project-specific waste.

Treat electrical, battery, mortgage and renovation results as preliminary planning estimates rather than guaranteed outcomes.

Confirm important technical, financial and safety-related decisions with the relevant qualified professional.

How we prepare our content

• We explain practical topics in plain language and avoid unnecessary technical terminology.
• We describe what each calculator can estimate, which inputs it uses and which factors may affect the result.
• We review formulas, unit handling, examples, result labels and safety limitations for consistency.
• We distinguish general planning information from personalised construction, engineering, electrical, legal or financial advice.
• We update pages when we identify an error, an unclear explanation or a way to make the method more useful.

Safety and responsible use

Safety is an important part of our approach. Electrical wiring, gas appliances, structural changes, major demolition and permanent backup power installations can create serious risks when they are planned or completed incorrectly. HomDera may help you understand the basic principles, review the logic of an estimate or prepare for a consultation, but final decisions must reflect the actual property, equipment, local requirements and installation conditions.

Project transparency

HomDera is an independent information website. We are not a construction company, do not provide renovation services and do not supervise work at individual properties. Formulas, examples and recommendations published on the site are intended to support early planning, comparison and self-checking rather than provide a final technical specification.

HomDera may display advertising to support hosting, technical development and the creation of new content. Advertising does not determine our calculation methods, safety warnings or editorial conclusions.

Corrections, suggestions and contact

We welcome corrections, suggestions and ideas for future guides or calculators. If you notice an unclear explanation, a possible error or a subject that deserves more detailed coverage, please use our Contact page.
