Commercial Development: The Investment Challenge
Industry Challenges
Commercial developments face intense market pressures and investment scrutiny:
Yield pressure - Every £100/sqm affects investment returns
Pre-let requirements - Tenants demand cost certainty
ESG expectations - BREEAM, WELL, net-zero targets
Specification creep - Grade A standards rising constantly
Timing constraints - Development windows closing fast
The Risk
“A 5% cost overrun on a £30M office development represents £1.5M in lost profit and can render a project unviable. Traditional estimation taking 6-8 weeks delays funding decisions and tenant negotiations when market conditions demand speed.”

Frequently Asked Questions
Q: What’s the largest commercial project you’ve estimated?
A: We’ve worked on office buildings up to 50,000 sqm and mixed-use developments exceeding 100,000 sqm total area. Our 5D BIM workflow scales effectively for major commercial projects including multi-tower developments.
Q: Can you separate shell & core from CAT A fit-out costs?
A: Absolutely. We routinely provide cost breakdowns showing base build (shell & core), landlord fit-out (CAT A), and tenant fit-out (CAT B) separately. This is essential for investment analysis and lease negotiations.
Q: How quickly can you provide a feasibility estimate for investment decisions?
A: For early-stage feasibility estimates based on concept designs, we can provide cost ranges within 2-3 days using benchmarks and parametric estimating. This gives investors the confidence to proceed to detailed design.
Q: What if the tenant wants different specifications after your estimate?
A: Because we work with 5D BIM, we can quickly recalculate costs for specification changes within hours to a day. This is particularly valuable during pre-let negotiations when tenants request variations.
Q: Do you include BREEAM/WELL certification costs?
A: Yes, we include both the construction cost premium for achieving target ratings (e.g., BREEAM Excellent) and the professional fees for assessment and certification. We can model different rating scenarios to help optimize investment returns.
Q: Can you provide cost breakdowns by floor or phase?
A: Yes, we regularly prepare cost breakdowns by floor, wing, or construction phase. This is particularly useful for phased developments or buildings with varying specifications across different floors.
Q: How do you handle complex MEP systems like VRV/VRF?
A: We have extensive experience costing advanced MEP systems including VRV/VRF air conditioning, displacement ventilation, and sophisticated BMS controls. Our estimates reflect the complexity of modern Grade A office specifications.
Q: What’s your fee structure for commercial projects?
A: Fees vary based on project size, complexity, and timeline. As a rough guide: - Small office (1,000-5,000 sqm): £3,000-6,000 - Medium office (5,000-15,000 sqm): £6,000-12,000 - Large office (15,000-30,000 sqm): £12,000-20,000 - Major/mixed-use (30,000+ sqm): £20,000-40,000
