A family focused garden room

In early 2021 we were asked to build a garden room in Maidenhead. Our initial brief was to give a like for like quote in comparison with a well known garden room company based on a picture in the brochure alone.

The main use for the room was to be work, and relaxation, with the added bonus of being able to banish the young adult daughters when they invited friends round. It was suggested that Steve would be setting up his train tracks, but that idea was very quickly dismissed by everyone else in the household.

Initial measure up and site survey brought up a range of issues that are typical to most garden room projects.  Sloping garden, overgrown hedges, old garden building to demolish, difficult access, etc.  But nothing that couldn’t be handled as part of the build process.

After the initial quoting process and consultation, a number of bespoke items were then added. This included a rear utility patio area for greenhouse and storage, new raised vegetable and fruit beds with fruit cage, an outdoor seating area and composite decking, along with a garden path.

  • Cedar batten cladding

  • Small kitchen area

  • Composite decking area

  • Outdoor seating & dining

  • Green wall

A smooth build process from start to finish


We started by pouring the concrete slab footing, then laid a plastic lumber sub-frame. The next stage was to build the framework of the building from pressure treated softwood and apply a breather membrane to the external side of the framework.

We then fully insulated the building between all joists in the walls, floor and ceiling before cladding the external walls with cedar batten from Silva Timber. The roof structure was built from 200mm x 50mm timber with an OSB deck, and finished with a rubber membrane courtesy of Rubber Roofs.

We stained the external cedar with Osmo UV protection oil, which enhances the beautiful colour of the cedar and prolongs the lifespan.

Internally, everything was plastered and painted, before installing the engineered flooring. A late addition was a small kitchen set-up with fridge and drawers/cupboard along one side of the room, and a floating bench along the other.

We used Envirobuild  for the composite decking at the front of the building to create a lovely outdoor dining and seating area. A green wall comprised of ferns and a number of trailing evergreens finished this area beautifully.

As you can see from the pictures below, the end product was a stunning space that the clients are absolutely delighted with. 

"We cannot recommend Thames Valley Landscapes enough. Steve and I had ideas of how we wanted the Summerhouse and garden to look, and worked with Paul to design and achieve them. Paul has a wealth of knowledge, offering lots of options regarding materials, finishes and types of plants for green wall and planters. The team were a pleasure to have around, and nothing was a problem to change or update.
We are absolutely thrilled with the result which has exceeded our expectations and have really enjoyed working and entertaining in this new space that has been created."
