Construction company website with project portfolio

We run a construction company and we need a modern, trustworthy website that clearly demonstrates the quality of our work and brings us more requests for cost estimates. The heart of the site should be a portfolio of completed projects: private houses, residential communities, commercial buildings and industrial facilities. Each project needs its own page with a gallery of before-and-after photographs, a description of the challenge, the technologies we applied, the materials we used and the construction timeline. A dedicated services section must cover our full cycle: design and planning, foundations, monolithic and brick work, roofing, facades, engineering networks and turnkey finishing. We also want a clear step-by-step overview of how we work, from the first site visit and estimate through to project handover and warranty support, so that clients can see how transparent the process really is. The key feature is a convenient request form for a cost estimate, allowing visitors to attach a plan or photographs of their plot. The website must load quickly on phones, rank well in search and inspire confidence through a solid, tidy design without unnecessary clutter.
