Extend your garden room with a hot tub shelter

Swift Unlimited garden rooms extended with a covered area for a hot tub, some open-sided and some walled, with skylights in the canopy and lighting on its underside.

One of the great joys of a garden room is that it allows you to enjoy your garden regardless of the season or weather. These rooms can also be tailored to how you plan to use the space, especially if you collaborate with a bespoke design specialist. Incorporating features that maximise your time in the garden is not only practical but also beneficial for your health, as widely documented.

A popular way to enhance the indoor-outdoor lifestyle that a garden room offers is to add a sheltered outdoor area next to the fully insulated room. These covered areas are favoured for creating outdoor seating or dining spaces. Another increasingly popular option is to design a sheltered spot for a hot tub, thus creating a multifunctional outdoor space that allows you to retreat for various activities-a growing trend in garden room design.

Swift Unlimited has crafted several garden rooms that have been extended with a hot tub shelter, as shown in the photos in this article. As we can see, no two projects are the same. This uniqueness stems from Swift Unlimited’s specialisation in bespoke designs, tailoring the size, layout, and design features to each client and their specific garden needs.

At a glance

  • The idea: A covered area alongside the insulated room, sized and shaped for a hot tub.
  • Structure: Foundations designed for the weight of a full hot tub.
  • Options: Open or solid walls, a skylight in the canopy and lights set into the underside.
  • Design: Doors placed for moving between the room and the shelter, with the cladding detailed across both.
  • Company: Swift Unlimited, who design each building around the client’s garden rather than to standard sizes.

Hot tub area

Garden room with hot tub area

Swift Unlimited is among the most experienced names in the garden room industry, knowledgeable enough to calculate the weight of a full hot tub and design the foundation system accordingly.

As bespoke designers, Swift Unlimited is not limited to standard sizes or footprint shapes like many other companies. Instead, they start with a blank sheet, designing the garden room around your requirements and the space you have selected in your garden. They use Structural Insulated Panels (SIPs) for the core structure of their buildings, creating a highly insulated room that can be comfortably used year-round.

The Swift designers can tailor the size of the covered area to your needs. As these photos demonstrate, you can choose whether the walls are left open or are solid. A delightful feature of some of these projects is that Swift Unlimited can incorporate a skylight into the roof canopy, enabling you to gaze at the clouds as you relax in the hot tub.

Swift Unlimited has a knack for making their covered outdoor areas an integral part of their garden room designs, rather than just an add-on. They position doors for easy movement between the insulated room and the covered area and detail the exterior cladding so the two spaces work cohesively together. Swift Unlimited can also incorporate exterior lighting into the underside of the covered areas, allowing you to enjoy your hot tub area in the evening.
