This is a measurement of how strong the timber is. The timber's characteristics are graded against permissible limits for the timber species. The higher the number, the stronger the timber. A common strength class in the UK is C16. We only use timber of C24 to C40 (more in line with demanding Scandinavian requirements) to ensure the highest quality possible.
We favour Siberian larch for our timber frame builds because of its excellent durability, dimensional stability (minimal shrinkage/swelling), and aesthetic beauty. It grows very slowly, making it extremely dense and strong when compared to other softwoods. In fact, Siberian larch is one of the toughest and most durable softwoods in the world. It can be painted or treated to maintain its strawlike colour, or when weathered it transforms to a beautifully consistent silver/grey, which is highly desirable in many cladding projects. Siberian larch should not be confused with the dark pink British/European larch that grows faster and not as dense in a warmer, wetter climate. Siberian larch also contains fewer knots – for a clean, contemporary, and consistent look – and, unlike British/European larch, its knots are light in colour and remain solid, even after drying and machining.
Alternative to timber frame construction, offering the traditional log cabin look of timber inside and out with interlocking exterior feature corners. Constructed logby- log, rather than from sections/panels, this type of build is well suited to sites with restricted access. Log buildings are available as single or twinskin glulam.
A selection of our models can be classed as a 'mobile home'. Built to our usual residential house standard for all year round enjoyment (not the flimsy, substandard BS3632 specification associated with holiday parks), these can be up to 20 x 6.8m and feature multiple bedrooms. The big advantage is that if the building is going in the grounds of your main house, you could add new living space without needing planning approval and increase the value and use of your property.
Creates a super insulated energy efficient home, with tiny heating bills, minimal carbon footprint, lots of natural light and superior levels of comfort compared to normal homes. We can design passive house technology into our residential models. The interior maintains a comfortable temperature – from the coldest day of winter to the hottest day of summer – without traditional heating and air- conditioning systems. The thickness of the walls, roof and floor is greatly increased and all glass upgraded to argon- filled triple glazing to achieve the incredible levels of insulation and Uvalues required. A mechanical heat recovery ventilation system provides a constant supply of fresh air using only a fraction of the energy consumed by a typical house.
Single-storey outbuildings can be considered as permitted development; without needing planning permission. Located to the rear or side of a property, they must be ancillary to the main dwelling and not contain living accommodation – office/studio space for example. The footprint can be up to 50% of the total area of land around the house. The maximum height for a dual pitch roof is 4m (3m for other roof types [e.g. mono pitch or flat]), and 2.5m if within 2m of the property boundary. Building regulations approval is not usually required up to 30m2 in floor area (no sleeping accommodation). More information can be found at www.planningportal.gov.uk
Full planning permission is normally required if a building does not fit the criteria for a 'mobile home' or a 'permitted development'. More information can be found at www.planningportal.gov.uk
Type of log construction featuring a single wall layer, or skin. With only one wall layer, plumbing and electrics are facemounted – so pipes and cables (inside conduit) can be seen running along walls – and the wood itself is the insulation. For hidden electrics and plumbing, and additional insulation see 'twinskin'.
Timber is the only mainstream 100% renewable building material. Increased demand means increased sustainable managed forest to supply it, so its a win-win situation. Timber has the lowest embodied energy and best thermal insulation properties of any mainstream building material. Our timber is FSCapproved and comes straight out of the forest and into the mill, so handling is minimal. Our timber buildings are built to order and precision engineered in factory-controlled conditions, so wastage is minimised, and so are post erection quality/snagging issues. Timber buildings are quick to erect, so on site construction time and resources is greatly reduced.
Constructed from sections/panels with full insulation built in, this type of build gives you a plasterboard interior finish inline with modern houses, with plumbing and electrics hidden behind. It’s an ideal option if building regulations is required. The exterior features vertical Siberian larch cladding to provide a clean, contemporary, and consistent look.
Type of log construction featuring two wall layers, or skins. The plumbing and electrics are hidden between the two wall layers. Insulation is added here too, which makes twin-skin a good option for residential log builds, particularly if building regulations are required.
U-values (also known as ‘heat transfer coefficients’) are a measure of how effective a building element (such as a wall, floor, roof, etc) is at preventing heat from transmitting between the inside and the outside of a building. The lower the Uvalue, the less energy is required to maintain comfortable conditions inside the building. U-value requirements are part of meeting Building Regulations. Our buildings are designed to be high performance. High levels of insulation and quality features such as double, triple, and argonfilled glazing ensure low U-values, all the way to passive house standards – like we’ve achieved on our show home.
