Only £4,000 Extra to Protect Against a Full-Grown Tree When Building a Studio-Size Extension — Because You Will Never Go Deeper Than 2.5m

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” […]

🏗️ The Complete Guide to Building Control–Approved Foundations Under £15,000 (Using One-Day Milestone Management)

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 […]

How a Rear or Side Extension Is Built — Full Construction Sequence Explained (AGC System)

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 […]

Why a 40m² Studio Flat in London Costs £220,000—When the Real Build Cost Is Only £40,000

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 Crane Support Beams Explained: How Internal Crane Supports Really Work

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 […]

Cast-In Steel Supports Inside Circular Columns for a Moving BMU Cradle System

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 […]

Structural Design of Dock Levellers – Full Engineering Breakdown

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 […]

Structural Design of Steel Catwalks for MEP Maintenance Platforms

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 […]

Stainless Steel Cat Ladders Inside Water Tanks

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 […]

🧱 Structural Design of Glass Balcony Partitions — Engineering Clarity and Safety in Modern Architecture

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 […]
