Buying questions

Garden Room Annexe FAQs

How much does an NFF Garden Room Annexe cost?

The final cost depends on the dimensions, glazing, internal layout, specification, site requirements and optional features. Use the instant quote or contact NFF for current pricing.

What is included with the Garden Room Annexe?

The published standard features include a site inspection and measure, full insulation, double-glazed windows and doors, EPDM roofing, treated timber cladding and eligible local delivery and installation.

Is the Garden Room Annexe fully insulated?

Yes. Full building insulation is included in the published standard specification, together with double glazing and an insulated, moisture-resistant floor.

Can the size and internal layout be changed?

Yes. NFF builds each Annexe to order, allowing the dimensions, glazing, doors, finishes and internal arrangement to be discussed around the available space and intended use.

Can a Garden Room Annexe be used for sleeping?

Sleeping accommodation may be possible, but it can change the planning, building-regulation, fire-safety and service requirements. Confirm the proposed use before the Annexe is designed or ordered.

Does a Garden Room Annexe need permission?

Requirements depend on the building’s size, position and intended use. Sleeping accommodation or independent living facilities can require planning permission and building-control approval, so the proposal should be checked with the relevant authorities.

What base and service connections are required?

The Annexe requires a stable, level base. Electricity, heating, internet, water and drainage requirements depend on the intended layout and should be agreed before manufacture.
