If you’re thinking about adding a conservatory, extending your kitchen, or even building a brand‑new house, the first step is to get clear on the basics. The UK has its own set of rules, cost drivers, and common pitfalls that can turn a smooth project into a headache. Below you’ll find the most useful points from our collection of guides – all written in plain English.
Foundation cracks. A crack wider than 3 mm may signal real trouble. Measure the width with a ruler, note any growth over a few weeks, and call a structural engineer if it’s widening or paired with sagging walls.
Planning permission. Many extensions qualify for Permitted Development, meaning you can build up to 8 m high for a detached house without a full application. Still, check your local council’s limits on side extensions and browse our guide on “How Big Can You Extend Without Planning Permission?” to avoid costly delays.
Choosing materials. For a long‑lasting home, look for strong, low‑maintenance options – think brick or block walls, high‑grade cement, and timber that’s been treated for damp. Our “Most Durable House Materials” article breaks down the best picks for different budgets.
Insurance coverage. Not every policy will foot the bill for foundation repair. Read the fine print, especially regarding subsidence, and ask your insurer what’s excluded before you start any major work.
Building a house can be cheaper than buying, but only if you control the variables. The “Build or Buy in 2025?” guide shows that new‑build costs average £1,500 per square metre, while purchasing a similar‑size home can be 10‑15 % higher after taxes and stamp duty. Look for bulk‑buy discounts on raw materials like sand, steel, and cement, and consider the “Cheapest Building Methods” to cut labour costs without compromising quality.
When extending, re‑use existing structures where possible. A well‑insulated loft conversion can add valuable space without the expense of a full‑scale addition. Just make sure the loft meets height requirements – a minimum of 2.2 m at the eaves is standard for most conversions.
Don’t forget the hidden savings from proper project planning. A clear schedule helps avoid “builder’s holidays” and reduces the risk of change orders, which often add 10‑20 % to the original budget. Our checklist for “When to Walk Away from Foundation Problems” can save you from sinking money into a property that needs endless repairs.
Finally, think about long‑term value. Installing a dry‑fit kitchen, as explained in our “Dry Fit Kitchen Explained” guide, speeds up installation and lets you tweak the layout later with minimal waste. It’s a small upfront cost that pays off in flexibility and resale appeal.
Whether you’re repairing a cracked foundation, planning a garden room, or mapping out a full new build, the key is to stay informed, keep a realistic budget, and pick reliable professionals. Use the articles linked on this page as a quick reference – they cover everything from cement choices for foundation repair to the biggest construction companies shaping the industry today.
