About Our Summerhouses with Side Shed
A summerhouse with side shed gives you two rooms under one roof. The glazed front section works as a sitting room or garden office. The lockable side shed stores tools, bikes, and the mower out of sight. Both sections share one roofline, so the building looks tidy. Prices start from £1,884 for the 12x6 model. These are timber buildings with tongue-and-groove cladding and felt roofing as standard.
This style suits anyone who wants a relaxing space without losing room to a separate shed. The shed keeps clutter hidden while the summerhouse stays clean. We always set them on a level base. For a workshop-first option, see our potting sheds. If you grow under glass too, look at a combined greenhouse shed. For a fully finished living space, browse our garden rooms.
Why We Chose This Range
"The separate entrances are the clever part. You reach the mower without walking through the nice room. We fit the Power Combi range because the shed door is wide enough to load a wheelbarrow. Customers tell us they wish they had ordered one sooner."
Matt, Founder of Greenhouse StoresMatt's Tip: Face the glazed front south or south-west for afternoon sun. Position the shed side nearest your access path. This keeps muddy boots and heavy tools away from the seating area.
Installer's Note: Base Preparation
The base must sit level across both sections. We use paving slabs on a compacted sand bed. Build it 50mm larger than the building on every side for water run-off. An uneven base jams the doors. It also opens gaps where the two sections meet.

Why I Recommend It: the 8ft depth fits a desk and a sofa, and the wider shed swallows bikes and a barbecue

Frequently asked questions
What sizes do these summerhouse combis come in?
Our Power range runs from 12x6ft to 12x8ft overall. The summerhouse takes the larger share of the footprint. The side shed fills the rest. Measure your space and allow 600mm clearance on every side for airflow.
Do I need planning permission for one?
Most fall under permitted development. The building stays single-storey and under 2.5m at the eaves. It must not sit forward of your house front. Conservation areas carry extra rules. Always check with your local planning office first.
What base does a summerhouse with side shed need?
A level paving slab or concrete base is essential. It must stay flat across both sections. Build it 50mm larger than the building for run-off. A poor base makes the doors stick and the cladding gap.
Can I use the summerhouse as a garden office?
Yes, many customers fit them out as offices. Add insulation between the studs and a 2kW panel heater. Run a weatherproof power supply from the house. The shed then hides your office clutter.
Is the side shed reached from inside the summerhouse?
Most models give each section its own outside door. So you reach the shed without walking through the living space. This keeps dirt and tools out of the nice room. Some larger builds add an internal connecting door.
