About BBS

Quality post & beam structures.

What you can get from us.

What we do:

Byron Backyard Studios make traditional heavy timber frame / post & beam structures.  We can make for you a range of structures such as : garden gazebo, pool house, ‘man-cave’, sleepout, workshop, shed, backyard studio, ‘tiny-house’, not-so-tiny house, garage with flat above, barn-house etc.

Our structures are made to a high standard, meet Australian Building Code, are engineer-approved and come with plans to subfloor for council submission.
Because customers want different finishing materials, and even changes to the frame design, we can price the frame, and estimate the finishing cost, to be better-defined once the customer has decided preference. Or you may choose to order just the frame, and elect to complete yourself or with your own builder.
We are based near Byron Bay, and can supply anywhere in Australia, providing there is a transport network to get the timber to you.

Who we build for:

We make for those who want a functional structutre, with quality workmanship and materials. Our customers tend to be those who recognise architectural merit, who appreciate artisan-grade workmanship and, not least, for those who love timber.

New World Dutch Barn

The ‘New World’…back in the 17th Century, the Dutch – amongst others, such as the Swedes and English, had their colonies in Nth America. The Dutch – and the Germans amongst them – began to build barns to meet their subsistence farm needs.  A simple design soon gained ascendency: a design with a central nave for threshing wheat and cart access, and an isle off each side of it for livestock pens (the British had their ‘English Barn’, of which there are hybrid versions with New World Dutch Barn).

The most prominent feature of the ‘NWDB’ is, arguably, the ‘anchorbeam’ : a long & deep, braced beam, hand-hewn from primal-growth forest logs, up to 9m long, with a tenon that passed through the nave post, to be anchored/pegged & wedged on the other side.

A loft floor for produce storage could be built atop these long beams. Rafters ran from the perimeter top plate, over the purlins above the nave post, to meet at the peak, and affixed to the rafter on the opposite side.

The NWDB was a feature of N-E American rural life – especially around New-York-New Jersey, where the Dutch settlers made their original base in ‘New Netherland’.

From the early 1600′s until the 1840′s, the NWDB served farmer’s needs, however, when the Industrial Revolution changed farming methods, the NWDB passed into obselecense and history.

Today it is a cherished and documented architectural icon in the Nth American historical and geographic landscape.

BBS can build a New World Dutch Barn for your rural property.  The design lends itself well to social venue use. And with some internal walls: am impressive barn-home ‘barndominium’, or function venue

We can build these engineer-approved frames barn-size, or backyard-cottage size, to suit your requirments.

Gambrel Barn House

The Gambrel is a frame from the American rural landscape. It’s two-slope per side allows for an upper floor/loft in what would otherwise be roof space. The lower slope in our gambrel design is steeper than the upper slope, for swift rain shed. A gambrel makes for an excellent office & warehouse, or character-filled home.

Heavy timber frame – P&B

Take a log, run it through a sawmill four times and you have dimensional lumber;  a large post or beam. Calculate, measure, mark and cut precisely and join multiple posts and beams according to engineer-approved plans and you have a heavy timber frame, or post & beam structure. Such structures lend themselves to showcasing the timber of which they are made, and can form great rooms with high vaulted ceilings and large openings ideal for sub-tropical and temperate living.

Milled post and beam structures are our specialty.

Log Construction

Take a log, debark it, pressure clean it …and you have… a log.

Collect a few more of these logs, calculate, measure, mark and cut, join them together with steel and chainsaw carpentry, and you have a log post & beam structure; a salute to and celebration of wood in its natural state. We are one also one of the very few operators in Australia who can produce hand-crafted full-scribe Scandinavian log cabins, appx 7 x 7m @ $98,000 excl.

Byron Backyard Studios can make up to 36 sqm cabins, capable of greater floor area with stick-frame lean-to off side walls. If you like the thought of a log post & beam cabin, we make them from termite resistant Cypress White Pine, and can make one for you. Crane access to property would be required for assembly, unless you own a team of oxen.

BBS Process

BBS offers production and supply of timber cabin kits, which are delivered unassembled.
You will need to appoint a builder to build the foundation and complete the envelope. We provide documentation and are happy to provide assistance;
our focus is on making the superior timber frame.

Unless otherwise arranged (and responsibility to acquire engineering certification thereby passes to the customer), all frame work is approved through a competent structural engineer prior to commencement of work; where customer-request production deadline necessitates this to start prior to engineer or local council approval, all effort will be made to design and machine to accepted engineering standard, but the risk is the customer’s.

Steps to getting your frame kit:

1) Either choose from one of the cabin kit frames on offer or draw a structure of your own.

2) Contact BBS to discuss your requirements.

3) Frame agreed-upon, contract signed and a deposit of 1/3 of the frame price is paid.

4) Your frame is produced and you will be kept updated on progress with email and pictures.

5) Plans and engineering excluding subfloor will be provided as standard, and should you choose: with subfloor on confirmation of footings.
We can assist with the application to council for your D.A, C.C, BASIX and occupancy certificate where required.

6) Prior to being sent, the balance of the sale price to be paid in full.

7) If we are involved in the frame assembly, we’ll raise it on a voluntary free-of-charge basis (excluding charges such as crane, hoist, scaffolding, fence, hold-downs etc).  If we are not involved with assembly, the frame will be designed to be assembled by competent people following a carefully-produced step-by-step procedure relevant to the customer’s particular frame.
