Can I look at the total before checking the details?
Use the total to understand the budget, but not to rank the firms yet. Ask both to clarify services, drawings, work items, specifications and terms. Compare the price difference for equivalent scope. Ask about unlisted items rather than assuming they are free.
Why can two firms quote very different prices for the same home?
Design outputs, drawing detail, revision rounds, construction scope, materials, measurement rules and site-management arrangements can differ. Find those differences first. A price gap alone does not establish which firm is better.
Must design, construction and management fees be separate?
Not every proposal uses the same format. Separate fee lines alone do not make a quote better. What matters is that services, deliverables and pricing can be traced. If a fee is bundled elsewhere, ask the firm to identify where and explain the inclusions.
What should I ask about site-management fees?
Ask about visits, trade coordination, material and stage checks, records provided and responsibility for defect follow-up. A percentage fee or a visit count alone does not define the full scope or its limits.
How do I compare quotes with different work-item names?
Match items by location and actual work, then compare scope, quantities, units and specifications. Ask the firms to explain unmatched items. Similar labels do not prove identical work, and unclear units should not be converted without the pricing basis.
Can SII identify the best interior designer?
No. SII reviews documents, not a designer’s or contractor’s taste, ability, creditworthiness or workmanship. You still need to consider design suitability, communication and delivery arrangements separately. Legal and engineering questions require the relevant professional advice.
