Studio Garden Room

Classic DIY Studio Garden Room Kit

Classic Self Build Studio

The Classic Studio is a fixed-spec version of our best-selling self-build garden room. It is a bright, versatile design suited to a garden office, studio or hobby room.

Classic Studio kits use SIP wall and floor panels with 75 mm insulation, an 80 mm PIR-insulated composite roof and a pre-adhered MDF internal wall finish on Complete Kits. The Classic range is supplied in selected sizes with no bespoke options.

With glazing spanning most of the front elevation, the Studio allows plenty of light into your room. Insulated panels make it suitable for year-round use.

FAQs

Yes, we can adapt any of our Premier rooms or create a bespoke kit to your size and specification, which we will provide a price for.

We provide a comprehensive installation guide with every room.

You will need to consider the type of base that your self-build garden room kit will be constructed on. Typically, we would expect you to need one of three types of foundation: pad, ground screws existing/new concrete base. You can use adjustable feet to level off the base. Please discuss with us the type of base you are considering as we progress your order.

The kit you have ordered will include the elements that are applicable to that kit and the SIP panels will be cut to size, ready for installation. Kits are delivered to the kerbside at the property.

Most rooms will not require planning permission and will fall under Permitted Development rights. However, if you are unsure, please seek guidance from your Local Planning Authority. All planning permission requirements are the responsibility of the Householder.

Thermowood, British Cedar and Western Red Cedar will all weather over time but do not require treatment. Composite cladding is maintenance free.

Premier Kits can be modified with additional/alternate-sized windows and doors and aluminium glazing if required. Prices will be quoted accordingly.

It takes 6–8 weeks from confirmation of your order and is subject to our production schedule.
