Apex Timber Buildings

Garden Rooms, Sheds and Summerhouses Teesside North Yorkshire

Materials & Construction

It doesn’t matter what you’re doing if you put quality in you get quality out, assuming whoever handles it knows what they’re doing! (See our section on assembly). We take this philosophy into all our timber buildings and the materials we choose to go into them.

Wood & timber supplies

We only use graded imported red / white wood. All our timber is selected prior to use, minimising shakes and knots. Where appropriate we use tanelised wood which provides protection against adverse conditions.


We use either 50x38mm or 75x50mm eased edge and PSE (Planed sides and edge) timber. Joists are set equally on all walls ensuring they don’t exceed 600mm centres. Compare this to other manufacturers, it may use more wood but we believe it is necessary for much greater strength for your building.


All buildings which include floors are fitted with either 25x125mm or 25x150mm tongue and grove flooring, floor joist centres do not exceed 400mm resulting in a very sturdy floor.


You can choose between either an Apex or Pent roof construction, (All Apex designs are constructed using ‘A’ frame trusses for maximum strength). Our roofs are clad using PTGV boards and finished in either Felt or attractive Asphalt High Density Shingles which have a 25 year life expectancy.

Occasionally we have enquiries for cedar roof shingles, which can also be supplied, however there is an additional cost for this type of material. If you have thought about a material that hasn’t been covered here please get in touch, we are always happy to work with customer suggestions to achieve new and inspiring designs. A copper roof maybe?

Guttering can also be fitted ask for details.


In order to deliver a quality timber building we believe it needs the same level of expertise to install it as it did to design and build it. That’s why all our timber buildings are delivered to your site and assembled by the same team who manufactured it in our Teesside workshop.

Our normal construction method is to build sections of the building off site in our workshop, and assemble at your location when ready, minimising the amount of time we need to spend at your site.

Where required we use pressure treated floor bearers which will ensure that your building is supported, elevated and level.

All the fixtures and fittings chosen for our buildings is done so with strength and longevity it mind.
We have a choice of finishes which will protect and enhance the appearance of your timber building.
Depending on the type of building you have chosen, you might want to consider installing insulation and or lining.
Utilities can add greater options fro your garden build and it's intended use.
Protecting your building is the secret to a long life for anything constructed of wood.
All our buildings require a solid level base, to ensure that your finished building is both properly supported and elevated to provide the protection from the weather
Adding gutters to your building to control where your water goes or even just to store it up for use when watering your garden.

We cannot recommend Apex enough! Steve was very helpful, he understood straight away what we wanted & designed a lean too for storage purposes together with a gate to access rear garden that more than met our expectations. Very pleased with the install and the team - who were all polite, tidy workers. If you are considering a build then look no further!

We are delighted with our beautiful corner summer house. The workmanship is excellent and nothing was too much trouble for Steve's very polite and hard working team. Great care was taken when erecting the structure so as to avoid damage to herbaceous border. First class service and would highly recommend.

These guys do a really good job at building their summer houses. We had ours in the summer after a long wait due to the popularity of these buildings during the shutdown. However the pre and post Customer Service is shocking. Before the build we seemed to be chasing them for information and now, post build, we have a window that needs changing. Two months ago they said it would be changed but I have heard nothing since their first e mail declaring this and I have sent 2 e mails since asking for an update. No use phoning as they do not answer. Its only a small window but why should I have the hassle and cost 3 months into the lifetime of the building? One month later and they turned up and did it. Think they were short staffed on the admin side a d that has been sorted. It does look great in the garden

We have a summerhouse from Apex and it is superb. We had a hand in the design, inasmuch as the height was increased for us because we are tall and we had the windows to fit our blinds and a couple of extra landscape windows included. We opted for insulation and boarding out and it is pretty toasty. My plan was to put in a log burning stove and we had a hole cut for the flue. It was erected quickly and tidily. I was left to sort out my wiring and sockets and the guys came back to put the insulation in and then fully board the walls and ceiling. Add WiFi and a telly and it is a very nice relaxing space. We thoroughly recommend the company. They are attentive and very skilled at what they do. I echo one of the other comments which is that they make some of the best timber buildings you will see. We are delighted. Kris and Mike, New Marske

We wanted a bespoke shed/blacksmiths workshop and that is what we got. We love our workshop, it did have a small problem which was quickly solved and now we are enjoying it. THANK YOU!
