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!

Are we too idealistic for our own good?


I received a call a few months ago for a soundproofed booth in someone's house.

All well and good, we do do them but normally they are for a voiceover booth within a soundproofed room.

The man who called was working from home and only required a 30 db sound reduction and only the booth. It was to be inside his house and he was a fair distance away from any neighbours so it was quite apparent he did not need mega suppression, not like we have to provide for drummers down the bottom of a short garden in central London.

So I asked him what he had now and he just had a really badly made DIY version, made with the wrong materials, (copious acoustic rockwool sandwiched between some plywood and then closed off with a standard internal wooden door).

Now that I know would have a sound suppression of diddly squat, so I told him what he needed to do to get it up to the low spec he required.

He asked me why was I being so open and doing myself out of a job.

Why, because he did not need a proper job I said. "You have done it so badly from what materials you have described, and the techniques employed, that very little has to be done in order to make it suitable for your purposes, as improving it is not a very onerous task as all, and this is what to do....."

He thanked me profusely for the information and we never heard from him again.

Now I know anyone else would have given him a quote for a soundproofed booth, and got on with it, however, his needs were so mild, I could not bring myself to do it, he just did not need a "proper job".


Another time I saw a drummer who wanted a very large 50db spec garden studio.

I went to do a survey and told him the price per sq metre for the different specs on a garden soundproofed room, and he really wanted the 50 db spec, this is normal anyway for drummers.

A year later he rang again and told us he wanted to go forward with it so he replied to our spec questions and details of design when asked and it worked out at over 90k plus vat.

I thought I had better check before I did too much work as often people sometimes never do a rough calculation, most do, but then are horrified at the price quoted, even though we are so upfront with the costs in advance, it is all there on the prices page.

But this guy was switched on and so when I called he said, that this was indeed the sort of price he was expecting.

So anyone else at this stage would have written back with the price of the quote as anticipated, 90 odd k plus vat and got on with it

Something did not feel right though. 

This potential customer lived in a huge house with a huge garden and his neighbours consisted of a commercial building 80 metres away and a neighbour with a house the same size as his, about 50 metres away, if not more.

50 db would be overkill I realised. The 40 db spec does not have the front wall including doors and windows, built twice, one behind the other, so the sound escape with a single thickness front wall, would be very predominantly through the front wall. Yet this faced his own house, as typically his studio was to be built at the bottom of the garden, so the person being in receipt of the worst of any escaping noise, would be himself, but he was the drummer making the noise!

So I rang back and had to tell him, he did not need 50 db in his circumstances, 40 db would be plenty. (Mind you, to be frank, I ought to have realised it from the outset but I think I was overawed with the size of this 50db job and cost at the time).

Now he was a little bit concerned that 40 db may not turn out to have been enough. I knew it would be enough, so I told him if it turned out after all, that if we did need to come back and upgrade it to a 50db retrospectively, we would just charge for the difference between the two specs.

To have done it this way would however have cost us a packet as all the plastering and finishing off of the first building would have to be scrapped and repeated, and so would a lot of other work as as this would be the largest one we had ever done, it was a biggie, our costs would be huge too.

Once I reassured him, he went for it. Why not anyway as it meant if I was right, he would save a tad over 20k plus vat, and if I was wrong, then he would only have to pay the price he was expecting to pay in the first place.

So we built it to the 40db spec as I had suggested.

We finished it and he paid up and all seemed ok.

After a few weeks. with baited breath, I rang him and asked how it was working out, he told me he was elated, and thanks so much he said for saving me that 20k, we just did not need 50 db here.

Good job and reason to be chuffed with myself I thought, but if it had gone wrong we would have lost a packet.

But are we not supposed to know what we are doing anyway? I think so.

Moved and improved!


About 12 years ago, we built our first 60db spec soundproofed room and although it was then a huge undertaking and we made a large loss. It was not supposed to be a money earner, it was supposed to be a subsidised experiment, as part of the learning curve just to see just how well we could do.

After much research we built it, and not only achieved our db drop goal of the time but exceeded it by a handsome margin.The customer was overjoyed and it went on to give good service for the next 12 years.

I should say that it survived him trying to burn it down as once he had a candlelit session and a candle set fire to some plastic acoustic foam he'd had fitted. It even spread to more of the same but luckily went out once it ran out of combustible materials inside. 

So when he asked us last year if we could relocate it to a location when he moved house, we visited and wondered if it was possible. We couldn't subsidise it as we had originally, and even at cost, relocating it 12 yrs later cost more than building it in the first place. (The initial bill did not reflect the true cost at all, we just took that on the chin at the time to see how far we could go!)

We never thought we could actually relocate it but we did. Relocating a 60db spec soundproofed room, the "room within a room" type is not an easy matter. Each one of our soundproofed studios, even small ones, has literally tons of sound blocking boards within it. Sandwich after sandwich per room and of course with one room sleeved within another this is a heap of work all doubled up.

It is not just the walls ceiling and floor, it is all the doors and windows too, plus he had a separate singing booth inside.

So we did it all again but this time we had a further 12 years of experience behind us and applied what we had learned, not just in soundproofing but aesthetics too. Gone were all the doubled up timber windows and doors, they were all replaced with Upvc versions, and this time there was no need for soundproofed shutters blanking them off as before, we have overcome this in the intervening years, so he no longer needed to close himself off and switch the lights on whenever he used it to make some big sounds.

This time it was a light and airy music room with a garden view at all times.

So here are a couple of photos showing it as we left it on site all those years ago, with the addition of some red paint (which we thought ruined it a bit) then how it is now in full glory.

An extra side of cedar has been added and it has been updated and improved all round, ready to continue to give decades more good service.

We've been exercising our minds!


Have you ever wondered why gym equipment takes up so much floor space? - benches, rowing machines, step machines... they all occupy their own footprint, taking up valuable floor space; permanently.

The technical team at Exra Rooms have come up with a revolutionary idea - A truly SLIM GYM™ taking up no floor space at all. 

We'd better explain!

Often, when our customers buy a garden room, for use as a gym they are keen to be able to use the room for other purposes, such as a play room or kids chill-out room. So the clever team at Exra Rooms have designed a unique gym that fits into the recess of the walls of your garden room, folding away neatly behing a pull down roller blind when not in use.

Just to show you how effective this is, we've taken the trouble to make a short film, which demonstrates clearly how this works and show you more of the features that come as standard when you purchase a garden gym and also buy one of our SLIM GYMS! (already patented with further patents pending).

Take a look... and if you are interested call Extra Rooms on the usual number and speak to one of the team today.

Just telephone: 01159 899 555 and tell them you read this blog post!

Pushing the boundaries


We do have quite a lot of photos of garden offices and rooms on our website, but as you can imagine, with most of our buildings being finished on the site the same day they arrive, unless it is in midsummer then it is dark by the time it is finished - this is what happened on this occasion.

However, a couple of years on, yesterday in fact, I was quoting for another garden room only 500 yards away and I told the potential customer that there was one of ours close by so they asked me to get permission to show them around.

I eventually found it and asked the ownerif it was ok and they agreed happily and asked me if I too wanted to see it and of course I accepted the invitation with curiosity!

How lovely it looked too, so much better than a bare building like many on our website.

Extra Rooms Blog -2-10-17

I remembered how we built it to as big as possible in order to both maximise space but also squeeze behind a tree in their garden. It was a tightish fit (and in fact since then the tree has grown a bit too!)

The customer was especially pleased with it because where it is sited there was just an unused corner with an old tree stump in it and so it took nothing out of the garden by having the building there.

It is always an advantage with the bespoke build of our garden rooms, with the cladding being on the building as it arrives on site. This means we can go really close to the boundaries, in fact nobody can go closer because we can touch the back fence if we have to, most companies have to leave a space to allow them to fit the cladding on site. 

This not only takes time on site, but also robs the customer of half a metre or even a whole metre of space in some cases. In turn this then makes for a much smaller building in many instances, but with Extra Rooms you get the max, more bang for your buck in effect!

Don't get me wrong, it is better to leave a bit of space to squeeze by at some time in the future if you have space to play with, but with us it is not a necessity.

So this building is an example of where you can have a garden building of a very useful size in the corner of the plot and when there is a nice path leading to it and some carefully placed plants nearby, making it an attractive feature as well as a useful one.

When is a garage not a garage?


It was a couple of years or so ago when we did this garden building, but the customer only sent these photos having finally got round to painting some of the cladding black. In fact I think it has all been painted now and looks fantastic.

Theirs was a large building, split into a garage and a large garden office.

We did not put in a floor for the garage as it had one underneath the old ugly concrete garage that sat there before, so we had some fun working out how to deal with the two different floor heights. 

In the end we brought the floor through from the studio section, a metre into the garage, where they could then mount their shelving units. It both simplified it for us and made life easier for them too as the old conrete garage base was wonky but good enough to park a car on. The racking could then sit on a level base protruding through from the room next door.

The whole point of the building was to create a large enough space, so that a growing family with teenage boys could benefit from the extra room and save them from moving house, as they have a cottage which was sometimes a bit cramped for them all.

So everything has worked out really well.

Here's what our customer Nick had to say:

"We couldn't be happier with our choice of Extra Rooms. Not only did they tailor a building to our needs and specifications but they were easy and great to work with. They also understood and respected our budget and worked brilliantly within it. The team who then came to assemble the building were highly professional and courteous. They basically became part of the family for the two days they were here and couldn't have been nicer to have around. The finish on the building, which is a garage and sizeable outside room, is excellent both inside and out. We highly recommended the design and build that you get with Extra Rooms".
