Vertical boards in thermally modified wood set the tone before the eye reaches the glass. The building reads as a custom wellness garden room, but the layout is broader than that first impression suggests. Behind the dark frames and clear panes, the interior is divided into a lounge, a garden office and a wellness zone. A concrete floor runs through the space and keeps the materials grounded, while the large openings pull daylight deep inside.

Wood, steel and glass in a compact footprint

The structure measures 10 by 4.5 metres, a proportion that gives the volume a long, low profile. That shape suits the mix of uses inside. The lounge sits close to the glass, the office can stay visually open, and the wellness area remains part of the same interior sequence. Thermally modified wood covers the outside in vertical lines, while black steel frames cut sharp rectangles through the elevation. The result is direct and legible, with each material clearly doing its own job.

From the outside, the steel framed glass facade is not treated as a decorative layer. It is a working part of the plan. The glazing marks the rooms behind it and shows how the custom garden room opens toward the terrace. In the images, the glazed doors sit next to the timber skin rather than fading into it, which makes the transition from enclosed room to outdoor seating area easy to read. The palette stays limited to wood, metal, glass and concrete, and that restraint keeps the building focused on space rather than effect.

Folding glass doors that open the lounge to the terrace

The folding glass doors are one of the clearest moves in the project. When they open, the lounge extends toward the paving outside and the seating area becomes part of the same route as the interior floor. The black frames remain visible even when the doors are closed, drawing a strong grid across the opening. Through the glass, the room feels connected to the garden without losing its definition. That is especially apparent in the wider views, where furniture, planting and the terrace sit in a single line of sight.

Inside, the concrete floor gives the room a firm base. White walls keep the background plain, which lets the dark window and door frames stand out. A black fireplace or stove sits against one wall and anchors the lounge in the middle of the plan. It is a small but important counterweight to the amount of glass. Instead of competing with the views, it gives the room a place to gather around when the folding doors are shut and the outside edge moves to the background.

A garden room that shifts between work, rest and wellness

The most interesting part of the layout is how easily the room changes register. One side can hold a desk and stay calm enough for work, while another part functions as a lounge. Further on, the wellness zone takes over, and the material language becomes warmer and more enclosed. Because the same timber, glass and concrete run through the building, the different uses do not feel isolated. The rooms are separated by function, not by a break in the architecture.

That mix of uses gives the project more depth than a single-purpose garden room. A custom garden room like this has to carry daily life as well as quieter moments, and the photos show that through small shifts in light and enclosure. One view looks outward across the terrace; another settles on the plain interior wall and floor; another steps deeper into the wellness side. The building never relies on one fixed image. It moves between them in a controlled sequence.

The sauna interior behind the quiet shell

Inside the sauna, the mood changes immediately. Vertical timber slats line the walls, and the benches are built in several levels so the space reads as layered rather than flat. Light washes across the wood, catching the edges of the seating and the slatted surfaces above. A glass partition keeps the interior visible and adds a clear boundary without closing the room off. This is where the sauna in garden room becomes the most specific part of the project, because the material detail is so direct.

The benches are not treated as loose furniture but as part of the room itself. Their pale wood contrasts with the darker lines in the glass and the surrounding frame. In one image, the light sits low enough to emphasise the steps in the seating and the regular rhythm of the wall slats. The effect is measured rather than theatrical. It lets the interior speak through construction and proportion, not through excess detail.

How the materials carry the whole composition

Thermally modified wood is the outer layer that ties the project together visually, but the reading changes as soon as you step inside. There, the concrete floor takes over as the main horizontal surface, and the white walls keep the room from becoming heavy. The steel framed glass facade adds precision where the timber softens the composition. Each material is easy to identify, which helps the building work as a portfolio piece: you can see how the room is assembled and how the functions sit within it.

The project also shows how a garden room can hold different atmospheres without splitting into separate buildings. One edge is open to the garden, another part is more enclosed for work, and the wellness zone sits behind that as a quieter layer. The presence of the sauna inside the same envelope gives the building its strongest identity. Together with the lounge and office, it turns the custom garden room into a compact plan with clear transitions, clear materials and a strong relation between inside and outside.

Small details that set the pace

Look closely at the black window frames, the pale floor, the timber slats and the glass reflections, and the project becomes easy to read. Nothing is overworked. The terrace paving outside lines up with the openings, the planting sits just beyond the glazing, and the interior furniture stays low enough to keep the view open. Even the sauna benches follow that same logic: simple forms, repeated lines and light that lands on the wood instead of hiding it. The wellness garden room is strongest when seen as a sequence of materials and thresholds rather than a single finished image.
