Q: How much extra will my foundation cost if I have a full-grown tree near my new studio-size extension? A: Only £4,000 anywhere in the UK. And you will never dig deeper than 2.5m. This question comes up in almost every enquiry for a 40m² studio-size extension. Homeowners are often told foundation costs will “double” […]

Most homeowners believe foundations for a rear extension, side extension, or 40 sqm permitted development build must cost £20,000–£35,000. This is the biggest myth in domestic construction. The truth is simple: A foundation is a one-day operation when managed correctly. By using a task/milestone workflow, prefabricated components, and the correct Building Control sequence, a full […]
When you look at a finished extension, it’s easy to focus on the final image — the glass, the lighting, the open-plan kitchen. But the real value is created long before the finishes. It starts with engineering, foundations, structure, and a disciplined construction sequence. This blog explains exactly how an extension is built, step-by-step, using […]
Are buyers really paying £160,000 just for paperwork, middlemen, and an old fit-out? London homeowners already know extensions, studios, and small builds are expensive to buy. But very few people realise how cheap they are to build. A standard studio-sized space (40m² — the England & Wales national minimum studio size) has a real construction […]
Tower cranes look simple from the street: a slim mast and a long jib swinging concrete and steel across the skyline. What nobody sees is the real engineering magic – the support system that anchors that crane safely into the building. In this blog I’ll walk through how a tower crane support system works, using […]
Modern high-rise buildings rely on building maintenance units (BMUs) to clean glass façades and canopies safely. The challenge is always the same: how do you carry a heavy moving machine and its rail system without cluttering the architecture or overloading the canopy itself? In this project the answer was to hide the structure inside the […]
Dock levellers are critical structural components in any logistics, warehousing, and loading-bay facility. Their function is simple: bridge the gap between a truck bed and the warehouse floor. However, the engineering behind them is complex, requiring precise structural modelling, load calculations, reinforced concrete design, and steel connection verification. This blog provides a detailed technical breakdown […]
Steel catwalks look simple. In reality they are complex structural systems that must carry people, tools and equipment safely above busy plant rooms. This blog explains how a suspended steel catwalk at basement level is designed and checked, based on a full calculation package and ETABS model for a real project 1. What is a […]
Safe access to water tanks is not just an architectural detail. It is a structural safety system that must carry concentrated loads, resist corrosion and remain stable for the life of the building. This blog explains how a stainless steel cat ladder system inside a large water tank is designed, analysed and checked, based on […]
Executive summary Glass balcony partitions can be both minimal and robust when they’re engineered as a system: tempered glass panel + point fittings + stainless bracket + tested anchors. Using finite-element analysis (FEA) for the glass and code-based checks for steelwork and anchors, the design below demonstrates adequate capacity and serviceability under dead, wind and […]
