Garden Room Price Calculation Formula
Total Cost = (Base Cost per m² × Total Area) + Additional Features + Labor Costs
Let’s break down each component:
- Base Cost per m²: This is the foundation of the calculation. It includes the basic materials and construction costs for a standard garden room. This figure can vary based on the quality of materials chosen.
- Total Area: The size of the garden room in square meters. Multiplying this by the base cost gives the initial estimate.
- Additional Features: This factor accounts for extras like premium windows, doors, electrical systems, plumbing, or custom interiors. Each feature adds to the overall cost.
- Labor Costs: The expense of hiring professionals to construct the garden room. This can vary based on location and the complexity of the project.
Some calculators might also include factors such as:
- Site Preparation: Costs associated with preparing the ground for construction.
- Planning Permission: Fees for obtaining necessary permits, if required.
- Delivery Charges: Especially relevant for prefabricated garden rooms.

Garden Room Cost Per M2
The cost per square meter (m²) is a crucial metric in estimating garden room expenses. This figure can vary widely based on several factors, but understanding the average range can help in initial planning.
Typically, the cost per m² for a garden room falls between £1,000 to £3,000. This range can extend in both directions depending on various factors:
- Basic Garden Rooms: At the lower end, around £1,000 to £1,500 per m², you can expect a simple, functional space with standard materials and minimal extras.
- Mid-Range Garden Rooms: Costing approximately £1,500 to £2,000 per m², these offer better quality materials, improved insulation, and more refined finishes.
- High-End Garden Rooms: At £2,000 to £3,000+ per m², these luxury spaces feature premium materials, advanced climate control, high-quality glazing, and bespoke design elements.
Factors influencing the cost per m² include:
- Quality of Materials: Higher-grade timber, superior insulation, and premium finishes increase the price.
- Complexity of Design: Unique shapes or architectural features add to the cost.
- Level of Insulation: Better insulation for year-round use raises the price but reduces long-term energy costs.
- Electrical and Plumbing Requirements: More complex systems increase the overall cost per m².
- Interior Finishes: High-end flooring, wall treatments, and built-in furniture add to the expense.
