Make the most of your outdoor space by adding a stylish, practical, and long-lasting garden building like this shed from Mercia Garden Products.

Those who are looking for somewhere to get away and enjoy some time to themselves won’t want to look further than this 7ft x 7ft Mercia Premier Corner Summerhouse. The versatile nature of this garden building means it can host large social occasions on one day, and then be a relaxing garden retreat on the very next. The unique shape also means it can tuck neatly into the corner of your garden, leaving plenty of free space in the rest of your garden for you to enjoy as you wish.

Made in the UK using FSC certified, high-quality shiplap tongue and groove cladding, the walls, floors and roof have been carefully designed to prevent water and draughts from entering the building. Solid wooden framing is added to the inside of the panels, this creates a solid foundation, meaning this garden room can withstand the harshest of the British weather. The classic pent roof provides a large amount of headroom inside, ideal for those who want to fit taller items, such as bookshelves and standing lamps. Large styrene glazed windows allow natural light to pour into the interior, this creates a bright and airy space that is always a joy to spend time in.

High-quality roofing felt is supplied as standard as well as detailed instructions ensuring a quick and easy assembly process. Finally, a lock and key are supplied with the double doors for added security. As with all Mercia garden buildings, this summerhouse is supplied with a 10-year anti-rot guarantee so that you can have confidence in the product you are purchasing. Simply treat your building with a preservative treatment after installation and annually thereafter and the guarantee and your summerhouse will be good as gold.

Rated 3 out of 5 by from Poor Quality in places We found it very difficult to put the front panel to the side panels as the angle they align up at does not allow you to put the screws through into each other. The wood had many splits and knot holes and was of poor quality. The build quality was very poor with nails being shot in and missing their intended piece of wood making this dangerous when finally built as sharp nails were protruding into the summerhouse. The instructions were poor and seemed to be a generic set for sheds and not type specific . The video was useful in places but was for a bigger summerhouse which seems easier to build. After a lot of fettling and alterations by myself we now have it built and treated it and it seems ok. This is not for the average DIY person as some building skills are needed to rectify the manufacturers faults and erect the summerhouse. Overall it was cheaper than other summerhouses but this shows in the poor quality materials that they use.

Rated 4 out of 5 by from Better than expected! Although it was a little tricky to erect, we got there in the end (the video provided in the item details was very helpful, in addition to the written instructions) and overall I am pleased with the product and it looks perfect in the garden. Having read previous reviews I was a bit concerned about the quality but we seem to have got lucky and received wooden components without defects, large knots etc. I think for the price paid, this is a good value product and I am very pleased with my purchase.

Rated 2 out of 5 by from It’s called premium - but it’s poor quality Had this delivered today, instructions are poor…wood is cheap, lots of holes and one side has faulty nails that was delivered with double nails sticking out. Also a crack in the plastic window. Delivery was on time and well informed.

Rated 1 out of 5 by from Do not waste your money! The summerhouse is very poorly made and very difficult to erect as the materials dulled are cheap and nasty.

Rated 3 out of 5 by from Functional summer house We purchased this for my father and whilst it is functional I was surprised we had to cut some of the facia boards as they should just be standard sizes, also you have to treat the wood after building it, the quality of the wood is not fantastic but he is very happy with it and he spends hours relaxing in there

Once up started to paint it and found screws sticking out nails not hammered all the way in! Loads of knots hard to paint so looks patchy!! Timber is not all the same some pieces are bad need alot of woodfiller to fill gaps!! Finding it hard to strip off the protective covering on windows!!!!! Wish I had bought a different make

Rated 4 out of 5 by from Premium 7ft x 7ft Very pleased with the summerhouse. It was quite difficult to erect, specifically connecting the front door to the 2 side glass panels. The angle was very difficult to get the screw in. However, once the facing went on, it looked great. I also had some issues with putting the roof on and ended up doing a slight workaround to make it fit better. But now that it’s built and painted - it is absolutely excellent. The quality is good too. I would recommend buying the summerhouse buy get a professional to build it.
