Factors Influencing Garden Studio Costs
The overall price varies based on design choices, construction methods, and added features. Some providers include foundational work, roofing, and flooring in their packages, while others offer separate options such as insulation, electrical wiring, and exterior finishes. Additional costs may also arise for specific components like foundations or insulation, which some companies price separately.

VAT
Most providers include VAT in their quotes. Excluding VAT might make prices seem lower; always confirm whether VAT is included before hiring a contractor.

Delivery Charges
Delivery costs are often included when construction occurs within a certain proximity to the provider’s workshop. If your site is farther away, extra delivery fees might apply.

Installation Costs
Installation is usually part of standard packages but can be an additional expense depending on the design.

Foundation Fees
Some companies incorporate foundation costs into their base price, while others require you to arrange or pay for foundations separately.

Insulation Options
Insulation ensures year-round comfort and is typically included in the base price, covering floors, walls, and roofs. Extra or upgraded insulation options may be available for additional costs.

Roofing Materials
The price normally covers standard roofing finishes like steel or asphalt shingles. Upgrades, such as EPDM rubber roofs known for durability, are usually extra.

Flooring Choices
Flooring costs, including laminate or skirting, are generally included, with options to upgrade to different finishes at additional expense.

Doors and Windows
Standard configurations are usually included, made from durable uPVC. Customizations or upgrades can incur extra charges.

Electrical Fittings
Power outlets and lighting wiring might be included in basic packages or offered as optional upgrades, depending on the company.

External Cladding
Finishes like cedar or redwood may be part of the standard package. Special or premium cladding options might cost more.
