Choosing a garden building is an investment, so it's important to buy from a company you can rely on. At 1st Choice Leisure Buildings, we've been helping customers find the right garden sheds, summerhouses, log cabins, garden offices and workshops

We live quite far away; is it really worth visiting our show rooms? Absolutely!
We strongly urge anyone looking for a new building – whether it's a new garden shed, summerhouse, workshop, garage, or a full garden room – to
visit and inspect the quality in person before committing to any purchase.
Seeing the craftsmanship, materials and finishes for yourself is the best way to make a confident and informed decision.
Whilst we cannot display everything we offer, we have carefully selected around 80 different buildings that allow us to demonstrate almost every feature, design option, and construction detail in one form or another.
This allows you to compare styles, sizes and specifications, ask any questions you may have, and find the building that best suits your needs.
So, yes, it is absolutely worth visiting.

1/ Working from home in Portsmouth, from the daily commute, is just one of the reasons to consider an office at home in your garden. It can be more enjoyable, you can be more creative with a calm, clear head – one which is not worn out by the 7.42 to Portsmouth. With the internet being so good these days, you can connect to the office as if you were there. Video conferences are easy to set up and to share with all your work colleagues. It improves work-life balance, and the extra time saved can be spent with your nearest and dearest. However, you do need to be disciplined with the hours you work. Don’t work in your nightwear; however, you don’t need to be in full city attire – just casual will do the trick.
2/ A Portsmouth garden room can help you achieve your ideal work setup. With a dedicated space, it’s easier to keep work and home life apart. You might also use a garden room for leisure, like setting up a gym or creating a spot for hobbies and crafts. Having this extra space lets you organise your things and spread out, which can reduce clutter and make your home feel more organised.
3/ Working outside the main house helps separate daily activities like eating, laundry, and television, creating a more focused environment. This separation supports balance and reduces stress. Having a dedicated garden office allows you to work independently and maintain control over your schedule.
4/ Any time of year is the perfect moment to reclaim your life, but there’s something about the fresh start of a New Year that inspires real change in how we live and work. After nearly five decades in the world of wood, I can tell you there’s nothing quite like it. Wood is alive, warm, and uplifting in a way that concrete, brick, or steel could never match. Imagine trading the dry, stuffy air of an office block for a garden home office where you set the mood and the temperature. Craving a breeze? Simply open your window and let the fresh air in. Try that in a corporate tower and see how far you get.
5/ Modern garden rooms can be surprisingly inexpensive if you take into account the benefits they can provide for you. Small garden offices often provide that bit of space you need to function perfectly. And even the larger, fully insulated building will be much cheaper than the equivalent home extension. Also, they are far easier to plan for and implement. With just the time a normal house extension takes to get planning permission in Portsmouth, you could have a new, delightful office in place. That’s got to be worth considering.
6/ Whereas you can work from home for your employer, the benefits multiply if you are self-employed or run a small business from home. Check out the cost of renting an office against buying your own office in your garden, including running costs. The difference is amazing. And when you have bought your new building, there is no rent to pay each month, so it doesn’t affect your bottom line. Quite possibly, just the first year’s savings from a rented small office may pay for your new Portsmouth building.
7/ All of our Royal, Fleet, and Odihaminsulated garden rooms are fully insulated and come with double-glazed doors and windows as standard. This energy-efficient design helps reduce heating costs for those working from home. Your new building will remain comfortable year-round, supporting a productive work environment while lowering energy bills.
8/ Your insulated garden building isn’t limited to being just an office—it can easily adapt into a home gym, a fun playroom, or anything else that fits your evolving lifestyle. You might opt for a sleek, multi-room design from the outset, with one area set up as your workspace and others used as a creative studio or a comfortable hobby space. Combining all these functions into a single structure creates a stylish timber retreat in your Portsmouth garden while also being more cost-effective than investing in separate buildings. We also provide a coloured finish option.
9/ The bottom line behind any purchase is how cost-effective it will be for you. That is one of the first rules for successful businesses. If your business is VAT-registered, you can normally claim VAT back on your purchase. It can get a little involved with tax and capital allowances, so it’s often a good idea to chat to your accountant to ascertain the best route to go down. It might be an idea for you to charge rent to your business for the use of your new insulated garden room for all business purposes. Again, your accountant should help you onto the right road.
10/ Always take the time to go and see various garden rooms and offices before making a decision. By driving from Portsmouth down to the 1st Choice Garden room show site (the showrooms have nearly 80 different garden buildings on display), you can walk inside, which should help you decide if the building is right for you. Talk to our garden room advisors, who will be happy to answer all your questions.
11/ Previous customers’ views are so important, so always take a look at what they are saying. Take a look at the feedback from our customers from Google, Trust Pilot and WhiteSpark. Sometimes we don’t get it 100% right the first time (but we try the very best to ensure we do), but we always follow through to ensure the best outcome for our customers.
12/ This brings us back to why you should be choosing a new garden room for your Portsmouth home. Keeping your home life and work in balance is key, as well as saving time and money. But there is nothing which beats owning your little world and sitting with nature in your garden. This is why you should consider the features that are important to you, the size of your new contemporary garden room, and the general layout that suits you. Do not rush this decision – talk to the experts and go view some examples of the building. Only by doing this can you appreciate the quality (or otherwise) and what your expectations should be. Don’t lower your expectations – only buy the building which is right for you. Or choose a bespoke garden room just for you.
