A two-storey extension adds bedrooms and living space at once, making better use of your existing footprint.
If your family has outgrown a single-storey addition, a two-storey extension is usually the more cost-efficient route per square metre, since you're spreading the cost of foundations and roof over two floors of usable space instead of one. It typically means extra bedrooms or a bathroom upstairs, with additional kitchen, living, or utility space below.
Two-storey extensions involve more structural planning than a single-storey addition -- foundations, matching rooflines, and tying the new structure into the existing house all need careful sequencing -- and are more likely to require full planning permission. We'll assess your specific site and give you a clear view on what's required before any design work begins.
| Scope | Typical Range |

| Small / basic scope | Lower end of the range |
| Medium / standard scope | Mid-range -- most common scope |
