Construction Feasibility & Budget Report

Know what your project could cost.
Before you commit to detailed design.

Practical, builder-led advice for your renovation, extension, second-storey addition or new home. Understand the likely budget, the big cost drivers and your next steps.

From $290 including GST · Personally reviewed by Hemmens Building

Clearer decisions. Earlier.

A builder’s perspective before expensive decisions are made.

Plans are exciting. Knowing whether the proposed work fits your budget makes them more useful. We review your project, explain the assumptions behind the figures and identify where the design may need to change.

Dylan Hemmens, your Central Coast builder

Personally reviewed. Practically grounded.

Work with a builder who understands the decisions ahead.

I’m Dylan. The aim is to help you understand what is realistic, where the uncertainty sits and what to investigate before you spend more developing the design.

We bring the same hands-on, cost-aware approach to feasibility that we bring to our building work.

Clearly labelled SAMPLE. Fictional project and figures only; not pricing for your project.

Concept-stage guidance

This is an indicative feasibility assessment, not a fixed-price building quote or engineering certification. Design, site investigations, selections and trade pricing may change the eventual cost.

Where information is incomplete, the report makes the assumptions and further investigation needs visible.

COMMON QUESTIONS

Know what you’re buying.

Do I need architectural plans?

Concept plans or sufficient drawings can be suitable for Desktop Feasibility. HB reviews whether they describe the scope adequately; not every sketch or incomplete document will be sufficient.

Do I need engineering?

No. Completed engineering is not required for early feasibility. Structural assumptions and any later engineering requirements remain visible in your report.

What if I only have an idea?

Choose Site Visit Construction Feasibility so we can discuss the scope and observe the property. The visit is coordinated directly with HB.

Is this a fixed-price building quote?

No. This is an indicative concept-stage assessment, not a fixed-price quotation, construction contract or offer capable of acceptance. It remains subject to design, engineering, selections, site conditions, approvals and supplier/trade pricing.

What happens if my project exceeds my budget?

We explain the major cost drivers and, where appropriate, identify project-specific alternatives, compromises or work that could be deferred. Potential savings have limitations and are not a guarantee that the entire brief can be achieved.

How long does the report take?

Indicative turnaround is 3–5 business days after sufficient information is received, subject to capacity. For site visits, this follows the consultation and receipt of sufficient information.

Can Hemmens Building help during design?

Yes. Discuss buildability advice, budget reviews and scope guidance with us as you develop your design. Further services are agreed separately.

What happens after the feasibility?

Take the Builder Design Brief back to your designer, investigate the identified unknowns, or discuss the next stage of pre-construction with Hemmens Building.

What areas do you service?

The advertised site consultation is available in the Central Coast and Lake Macquarie, NSW. Outside these areas, or unsure? Contact HB for individual assessment before purchase. Meetings are manually coordinated; no travel fees are automatically added.

Your next step

Start with clarity. Build with confidence.

Choose your feasibility package, or speak with Dylan if you’re unsure which option fits your project.

Continue with Hemmens Building: discuss buildability advice, design-stage budget reviews, scope guidance, value engineering and detailed estimating. Further services are agreed separately.
