Orangery Roof

Orangery roofs are an increasingly popular option for many people looking to add additional space to their property at a fraction of the cost of a larger extension.

Attic Re-Roof of Existing Property

Attic re-roof of existing property, Wolverhampton



In early 2018, E.T.S was appointed by a local builder for an extension, renovation and re-roof project in the West Midlands. The objective of the project was to utilise the existing roof void areas, and in conjunction with the increased size in the building footprint, allow for the maximum loft space available to incorporate two new bedrooms.

Attic trusses are a fantastic solution to achieving additional living space within a property. In this instance the footprint of the building was extended, but this is not a pre-requisite for achieving space within an existing roof void. By utilising our powerful, industry leading design technology – Pamir by Mitek industries – we are able to generate designs that comply with ridge height planning restrictions, in this example with the inclusion of a flat roof area, whilst maximising the habitable areas of the building.

Metal Web Joist Supply

Multiple plot new builds, Metal web joist supply in Oxfordshire.


Earlier this year E.T.S was appointed as the metal web joist supplier for a multiple plot site, in Oxfordshire. The site comprised of 3 & 4 bedroom properties and it was crucial to the builder that a firm feel to the floor was achieved. As such the use of E.T.S’s posi-joist solution (metal web joists) was the perfect choice for this project, due to their increased strength and spanning capabilities in comparison to alternative timber joist solutions such as I-beams or solid timber.

Further reinforcing the argument to use posi-joists, this project required steel beams to be hidden within the floor zone. The nature of posi-joist design allows E.T.S’s team to manipulate the design of the joist to accommodate a variety of scenarios, be it for top-chord supporting onto steel or timber beams, building into blockwork, lapping joists to ease with decking installation and many more…

Raised Tie Roof Extension

Peter and Megan Anderson – Raised tie roof extension near Kidderminster


Following approval of their planning application for a large extension to their property, Peter and Megan requested a quotation from E.T.S following a word of mouth recommendation from a previous customer. The roof design was made incredibly complex as a result of the skewed wall along the boundary line – maximising the build footprint. The requirement for a vaulted ceiling combined with an ICF (insulated concrete form) wall construction added additional design difficulties.

Here at E.T.S we relish the opportunity to get involved with more unusual, complex projects as it draws upon our vast design experience and keen attention to detail, as such we were delighted to secure the order.
