New Construction: What You Need to Know Before Building

Starting a new build can feel like you’re stepping into a maze. Where do you begin, how much will it cost, and what headaches should you dodge? Below you’ll find straight‑to‑the‑point advice that helps you plan, budget, and avoid the most common problems.

Planning Your Budget and Choosing Materials

First up, budget. A 2025 UK report shows the average profit margin in construction hovers around 8‑10%, which means you’ll see a markup on every material and labour line. Keep a buffer of at least 10% for unexpected items – think extra plaster, change‑order fees, or a surprise permit.

When it comes to picking materials, don’t chase trends blindly. Concrete, steel, and wood remain the backbone of any structure. Concrete offers durability and fire resistance; steel gives you strength without bulk; wood provides a warm finish but needs proper treatment against moisture.

If you’re updating a living area, engineered hardwood and luxury vinyl plank are the hot flooring picks for 2025. Engineered hardwood mimics solid wood but resists humidity, while LVP handles traffic and is easier on the budget.

Avoiding Common Pitfalls: Mold, Foundations & Roofing

New homes can still develop mold. Moisture gets trapped when vapour barriers are missing or when insulation isn’t sealed correctly. Look for signs like a musty smell or visible spots on walls, especially in bathrooms and basements. Using mould‑resistant drywall and keeping indoor humidity under 60% cuts the risk dramatically.

Foundation problems are another landmine. Small cracks can turn into major structural issues if soil shifts or drainage is poor. Before you pour, have a geotechnical survey and ensure proper footing depth. If you spot cracks later, a professional can recommend piering or underpinning – just know that these repairs are among the most expensive fixes.

Roofing costs have also jumped. A $30,000 roof isn’t unheard of for a large, high‑spec home, but a typical 2,000‑sq‑ft roof can range between £8,000‑£12,000. Ask for a detailed quote that breaks down materials, labour, and any extra fees. Some contractors offer financing options, but read the terms carefully to avoid hidden interest.

Lastly, consider energy efficiency. Installing daylight‑mimicking lighting reduces electricity use and makes spaces feel larger. Pair it with good insulation and you’ll see lower bills and a healthier indoor environment.

By keeping an eye on budget, choosing the right materials, and planning for moisture and foundation health, your new construction project can stay on track and finish without nasty surprises.
