When considering a new garden building, size and materials play the biggest role in determining cost. Entry-level play units begin around R8 000, while larger or custom models can exceed R50 000. Beyond base dimensions, choices like cladding type, flooring, and extras such as decking or electrical kits all add to the final figure. Understanding how each factor contributes to the total helps you plan a budget that matches your needs.
Standard Sizes and Base Costs
Small play cabins measuring 1.5 m × 1.5 m often start at about R8 000. A basic wendy house in this footprint will include simple pine cladding, a single door, and small windows. Stepping up to a 2 m × 2 m model raises the starting price to near R12 000; these wendy houses for sale include larger openings and may offer built-in shelving options. For a hobby room or home office, a 2.5 m × 2.5 m unit usually begins around R18 000, featuring reinforced floors and lockable doors. Families seeking maximum space often choose a 3 m × 3 m cabin with multiple windows and optional decking starting at around R25 000.
Custom Dimensions and Their Impact
When your site calls for a non-standard footprint, expect a premium. Each extra half-metre in length or width typically adds R2 000–R4 000 to the base price, reflecting increased material and labour. If the ground requires elevated supports or concrete piers, factor in an additional R1 500–R3 000. Roof style also affects cost: while standard pitched roofs are included, flat or skillion profiles carry a 5–10 % surcharge due to different framing needs. Splitting a large cabin into two rooms with an internal partition and extra door generally adds R4 000–R6 000 for materials and installation.
Material Choices and Their Costs
The cladding material sets both upfront and long-term costs. Basic softwood boards cost roughly R500–R700 per square metre and require repainting every two to three years. A wooden wendy house built this way has a classic look but moderate upkeep. For lower maintenance, fibre-cement panels (often sold under brand names) run about R1 200–R1 500 per square metre, offering fire resistance and insect proofing with repainting only every five to seven years. Insulated sandwich panels, at R1 800–R2 200 per square metre, deliver better temperature control—ideal for guest rooms or home offices.
Flooring adds another layer: standard timber floors cost R300–R500 per square metre, while composite decking or laminate boards reach R600–R900. Roofing material choices range from corrugated iron at R150–R250 per square metre to higher-end Colorbond or Onduline sheets at R300–R450, which offer improved insulation and curb appeal.
Additional Features and Pricing
Many buyers choose to upgrade windows and doors. A standard single-pane window costs R600–R900 each, whereas sliding or double-glazed units run R1 500–R2 500. Lockable timber doors start at R1 200, with steel security doors at R2 000 and up. Adding a small timber deck (about 1.5 m × 1 m) typically costs R4 000–R6 000, and built-in steps add R800–R1 200 per riser. Interior linings in gypsum or plywood cost R1 200–R1 800 per square metre, and a basic electrical package starts at R3 000, excluding fixtures. Insulation batts for walls and roof range from R150 to R250 per square metre, with spray-foam systems at R300–R400 for specialist installation.
Tips for Making the Right Choice
To ensure you get the best value, start by comparing at least three detailed quotes that break down costs by square metre or metre run. Inspect material samples in person to judge finish quality and upkeep requirements. Read customer reviews focusing on durability, after-sales service, and adherence to quoted prices. Confirm delivery and site-preparation fees up front, and verify any workmanship or material guarantees. With a clear understanding of how size and material choices drive cost, you can select the ideal garden building—whether a simple play cabin or a fully kitted home office—that fits both your needs and your budget.
