Frequently Asked Questions
Q1: How accurate is the instant online quote?
The online quote calculator provides an indicative estimate based on typical project costs for your chosen project type and size. It is designed to give you a estimated starting figure before you speak to our team (terms apply). Estimated costs are confirmed after a free consultation, site visit and review of your specific requirements, including architectural drawings, structural calculations and any planning considerations.
Q2: What is the difference between Construction Only and Design and Build?
Choose "Construction Only" if you already have approved architectural drawings and planning permission and need a builder to carry out the construction work. Choose "Design and Build" if you need the full service from initial design through to completion, including architectural drawings, planning applications, building regulations, structural calculations and construction. Most of our customers choose the design and build option as it provides a single point of contact throughout the entire project.
Q3: Is the quote free and without obligation?
Yes, both the online instant quote and the follow-up consultation are completely free and without obligation. You can use the calculator to get an initial estimate, and then book a free consultation call to discuss your project in detail. There is no commitment at any stage until you decide to proceed.
Q4: What happens after I get my instant quote?
After receiving your instant estimate, we recommend booking a free consultation call to discuss your project in more detail. During the consultation, we will review your requirements, budget and timeline, and can arrange a site visit if required. A detailed estimate is then typically produced within 7 to 14 working days, depending on workload. Please note that all estimates are indicative and subject to change following final architectural drawings, site surveys and detailed specifications.
