[{"order":1,"question":"How does your Passive House approach translate to real comfort and savings in Denmark’s climate?","answer":"Denmark and the Great Southern have cool, wet winters and mild summers with coastal breezes. We design small and tiny homes using Passive House principles—orientation, high-performance insulation, careful airtight detailing, and smart shading—to stabilise indoor temperatures and cut heating/cooling demand. The result is a quieter, more comfortable home with lower running costs and reduced condensation risk, which is especially valuable in our damp, coastal conditions."}, {"order":2,"question":"Do you build both trailer‑mounted tiny homes and small fixed homes? What approvals will I need with the Shire of Denmark?","answer":"Yes—we build trailer‑mounted tiny homes and small, fixed‑foundation homes. Approval pathways differ:\n\n- Fixed homes typically require a Building Permit (and sometimes Planning approval) through the Shire of Denmark.\n- Trailer‑mounted tiny homes may be assessed differently (e.g., caravan/park‑home use) depending on how and where they’re sited and occupied.\n\nWe’ll guide you on the likely pathway for your property, coordinate documentation with your designer/engineer, and recommend early checks with the Shire to confirm local requirements for your zoning and intended use."}, {"order":3,"question":"What’s included in your quote, and how do you keep budgets on track?","answer":"We provide a transparent scope with clear inclusions and exclusions so you know exactly what’s covered. Typical inclusions are the specified structure, finishes, and fixtures; common exclusions (if applicable) are items like certain appliances, landscaping, or site‑specific services. We align the contract with the agreed scope, use local suppliers/trades to minimise surprises, and communicate proactively about any requested variations before work proceeds."}, {"order":4,"question":"How long will my build take, from first chat to handover?","answer":"Timelines vary by size, site access, and the level of performance detailing. A typical flow is:\n\n- Discovery and concept: 2–6 weeks\n- Design, engineering, and approvals: 6–12+ weeks (council timeframes vary)\n- Construction: 8–20+ weeks depending on whether it’s trailer‑mounted or fixed, and the complexity of finishes/performance features\n\nWe’ll confirm a schedule with milestones up front and keep you updated at each stage."}, {"order":5,"question":"Do you work outside Denmark, and can I see local examples before deciding?","answer":"We primarily serve Denmark and the broader Great Southern—commonly including Albany, Walpole, and Mount Barker. We’re happy to share our portfolio of recent local projects and, where practical, arrange viewings or references so you can see build quality and talk to homeowners before you commit."}]
