Sussex Garden Rooms

Studio Annex

We appreciate that sometimes the available space for an annex needs to fit within a terraced house garden, or indeed that the requirements are such that the occupant does not require a separate bedroom and living space. For that reason we have developed our Studio Annex, where the main space doubles as the living room and bedroom, with a separate shower room with sink and WC.

Frequently Asked Questions

Yes. You can build an outbuilding under permitted development, but to enable someone to permanently live in the annex requires planning permission. The main factor to consider is that your annex should not occupy more than 50% of your available garden, and ideally be a maximum of 2.5 metres in height.

Yes, at Sussex Garden Rooms we can handle all aspects of the planning application – including all necessary plans, drawings and dealings with the local authority. Our planning package service costs £1,500 inc VAT.

A garden annex build period is typically 4-6 weeks from start to completion.

We predominantly use ground screw foundations but also have a pad system to enable us to build up from an existing concrete base. All foundations costs are included.

All aspects of your annex can be customised to suit your needs and preferences, including the layout and external cladding, kitchen and bathroom designs, and aesthetic aspects like flooring and paint. Some of these may be subject to additional specification and costs. Read more in our full FAQ.
