A garden office blog from Extra Rooms

Welcome to Extra Room’s garden office blog.

We love sharing all our garden building knowledge and stories with you!

A sound bit of advice


Well, ExtraRoomers - we are building on 2016 - which was a record breaking year that culminated in the largest single garden room to date. Read on to learn more...

We pride ourselves in being the quickest installers of garden rooms in the UK, because we make them twice!

Let me explain - we make them once in our factory, then we take them apart and simply reassemble on site, so it's so much quicker than constructing them on site for the first time.

BUT this was not a normal garden room, it was a sound-proofed music studio, with a 40db suppression spec, and that is a very different kettle of fish! 

The layers of soundproofing materials must be heavy, the reason being that in order to suppress sounds effectively, you must have resilience, and mass.

The resilience comes from the special way we layer materials together to give them some space to move, and the mass, in this instance and with a building this size, comes from many, many tons of soundblocking boards.

Many competitors use factory made, pre-bought SIPS panels, but they are all made to a standard non sound-proofing spec. They have either polyurethane or polystyrene within sandwich of two layers, one each side, of oriented strand board. This has little mass and is not at all soundproof...

whereas our panels are bespoke, especially for soundproofed garden rooms, and the internal sandwich has a very dense soundblocking board, which can move when hit by sound, thereby getting a major head start on suppression before the sound even goes though the first layer of wall.

This board is cushioned either side to allow the boards within to move, and this de-powers the sound, especially the deep bass, even before it meets the internal wall surface layers.

This makes the panels far heavier than normal, which is good for soundproofing but makes them difficult to work with, so we reduce the size but add many more layers we get the db suppression to 40db.

For a 50db spec we add even more layers, some fixed, some movable by the sound as before, but that's another story!

Actually this customer thought he needed a 50 db room since loud drums were being used, this would normally be the case, but his neighbours were not immediately next to him, the glazed face of his building was towards his house, so we suggested we did a 40 db spec with construction that woudl make it easily into 50db retrospectively, if it was ever needed.

Once completed, the customer thrashed the drums and the noise levels were well low enough for his needs, so it was just as well we did it to 40db - the price difference was substantial, so he was doubly happy.

We are here to help with just that sort of issue - we make it our business to help you get the correct specification - after all we have years of experience and hundreds of happy customers.

How's it Overhanging?

We recently did a job near Bristol where the garden room was planned to face directly south.

This can cause problems if not taken into account, since even though this is what the customer wanted and insisted on, too much sun directly into a relatively small space can be a real issue. Luckily there are ways to compensate and there are quite a few choices.

The choices are blinds, tinting, solar glass, or an extended roof overhang/parapet roof, and each has its own pros and cons.

We are the suppliers of these buildings to the end user so we often have to bear in mind that when something fails, even something as minor as a blind, it could cause us grief, since even though our guarantee does not cover minor cosmetic issues it still reflects on us. So we plan to avoid these things happening as much as we possibly can.

We don't do blinds any more, tinting was ok most of the time, but it can get a bit dusty in our factory (any woodworking area has some dust!) and if we managed to get a bit of dust trapped behind a couple of window panes on a job at the far end of the country, we'd be going back to sort it out. So what is the most foolproof solution?

When directly facing the sun, the best, most permanent and least problematic approach, is a large roof overhang, a built-in 'canopy' if you will. Shade all the time when the sun is fierce and high up in the sky, but allowing that lovely early morning and late evening sun, at a sharp angle from the east in the morning and the west in the evening. 

That was our answer on this occasion, and exactly what was required for this particular building, oriented as it was.

Every customer is different and every building we do is different, so it's essential we give it some forethought to make sure that the customer's extra room, not only looks presentable, but works too!

The Artistry of Cladding - a tale of patience and passion

So we had a call from a lady in the Isle of Wight wanting a garden studio to use for her business dealing in stamps, collectables and artistic items.

We quoted and added a bit to help cover the costs of the extra travelling time and it was all duly accepted. Incidentally the customer mentioned later that in fact no other company she had contacted was willing to even consider installing in the Isle of Wight!

It is hardly an 'ocean crossing' but 'the competition' did not like it so we did it, no problem!

Anyway, the customer has an eye for patterns and also hates waste and likes to try to look after the environment, so with that in mind we got to tallking on the phone one day about the different tones of cedar.

I remembered as a child being told by my architect father that in some countries people were willing to pay more for reject bricks than ordinary ones of a consistent tone and colour. Reject bricks, if laid reasonably randomly in a wall, offer a mottled pattern which is far more interesting to the eye.

I suggested, if that was the case then would she like us to clad her garden room in cedar off-cut?

It was going to be a lot more time consuming so there would not be a cost advantage for her, indeed it was a bit of an unknown as we had never done that before, and in fact it really did take a lot longer as we ended up having to finger-joint each peace and glue them together in rows of three, it took ages, but I think she was right.


We think the resulting garden office looks excellent >
