Small Soundproof Garden Music Studio by Garden Spaces

This 6.7sqm garden music studio by Garden Spaces is the smallest soundproof studio we have featured on The Garden Room & Annexe Guide, and a useful example of how a professional-standard acoustic garden room can be created on a very modest footprint.
Built for a full-time musician in Leytonstone, the building measures 2.23m x 3.8m externally, with internal dimensions of 1.81m x 3.38m. Garden Spaces has used height, layered acoustic construction, and a specialist porch detail to make the studio as capable as its larger counterparts.
That height matters. Most near-boundary garden rooms are designed to stay within the 2.5m height commonly associated with Permitted Development. This studio rises to 2.83m at its highest point, allowing a 2.5m internal ceiling height. The extra volume will have helped both the feel of the room and the acoustic brief, but it also meant planning approval formed part of the route to delivery, something Garden Spaces handles as part of its turnkey service.
A Compact Studio For Serious Daily Use
The brief was straightforward but demanding: create a dedicated workspace for a professional musician on a site with very little room to spare. Access was only through the main house, there was minimal on-site storage, and the acoustic standard needed to go well beyond what most garden rooms are asked to achieve.
Garden Spaces is one of the few companies in this sector to set out a structured acoustic offer, with several levels of specification depending on how the room will be used. Here, the owner chose the Platinum package, which adds soundproofing treatments to the ceiling, walls, and floor structures.
Acoustic Porch Detail
One of the details most associated with Garden Spaces' music rooms is the acoustic porch. It is particularly impressive here because, on such a compact footprint, it would have been easy to strip the design back to the bare minimum. Instead, the team has retained one of the details that helps distinguish their acoustic work from more standard studio specifications.
The porch creates a small buffer zone before the main room, with a second door, specialist seals, and glazed elements helping control sound transfer. It also gives the front elevation more architectural depth. Rather than a flat front wall with one simple opening, the stepped form allows a tall window to sit alongside the entrance, bringing daylight into the studio and maintaining a stronger connection with the garden than might be expected in a building of this size.
The porch walls and ceiling are plastered, the door architraves are resolved as neatly as they would be in a much larger room, and the coir matting feels like a considered choice rather than an afterthought. Just because the footprint is small, it does not mean the quality has been pared back.
Platinum Layers Over the SIP Structure
Garden Spaces builds its rooms from SIP panels, then adapts the internal build-up according to the required acoustic performance. On the Platinum specification, the SIP shell is supplemented with de-coupled fixings, metal furring strips, acoustic mineral wool, a rubber acoustic mat, and double acoustic plasterboard internally, together with extra treatment to the roof and floor build-up.
That layered approach is worth noting because it shows how soundproofing is being achieved. Rather than relying on one product or simply making the wall thicker, Garden Spaces combines mass, separation, and absorbent materials to create a more controlled acoustic envelope.
High Quality Finishes Inside and Out
The main visible elevations are clad in Thermowood, fitted vertically so the rich honey-brown tone reads cleanly across the compact form. Thermowood is a heat-treated softwood known for durability and relatively low maintenance, and it works particularly well here against the anthracite grey doors, windows, and trims.
On the less accessible elevations, Garden Spaces has switched to cement particle board in a matching anthracite finish. Where future maintenance access is awkward, a lower-maintenance material makes sense, and the detailing here looks crisp despite cement board being less forgiving to work with than timber cladding.
Inside, the room is finished much like a new-build house, with plastered and decorated walls, laminate flooring, and an electrical layout tailored to the client. Garden Spaces also specified a quiet-running air-conditioning system to manage temperature and airflow without undermining the point of creating a properly controlled studio environment.
A Challenging Site, Carefully Managed
The practical challenges behind the build should not be overlooked. With no direct external access, every material had to be brought through the house, deliveries had to be tightly managed, and the team had very little space for on-site storage.
What makes the finished project stand out is that those constraints do not read as compromise. The result is a compact but properly specified garden music studio that shows what an experienced specialist can achieve when the brief, the structure, and the acoustic package are aligned from the outset.
