Residential Development: The Complexity Challenge
Industry Challenges
Modern residential developments face multiple pressures with tight margins:
Planning constraints - Height limits, density, parking requirements
Complex regulations - Building codes, fire safety, accessibility
Tight margins - £2,000-3,500/unit profit requires precision
Multiple unit types - 1-bed, 2-bed, 3-bed variations
Design iterations - Value engineering vs quality balance
The Risk
“A 5% cost overrun on a 100-unit apartment building represents £500,000+ in lost profit. Traditional estimation methods taking 6-8 weeks delay decision-making when market conditions and planning approvals demand speed.”

Frequently Asked Questions
Q: What’s the largest residential project you’ve estimated?
A: We’ve worked on developments ranging from 10-unit townhouse complexes to 200+ apartment towers, including mixed-use developments with retail and commercial elements. Our 5D BIM workflow scales effectively for any project size.
Q: Can you handle mixed-use developments with retail/commercial elements?
A: Absolutely. We regularly estimate mixed-use projects combining residential, retail, office, and parking elements. We provide separate cost breakdowns for each use category and handle the interface complexities between different uses.
Q: How quickly can you provide a feasibility estimate for planning applications?
A: For planning-stage feasibility estimates based on concept drawings, we can typically provide a cost range within 2-3 days. This uses benchmarks and parametric estimating appropriate for early-stage decision making.
Q: What if the developer wants to change the unit mix after your estimate?
A: Because we work with 5D BIM and unit type libraries, we can quickly recalculate costs for different unit mixes within hours. This includes adjusting the balance between 1-bed, 2-bed, and 3-bed apartments.
Q: Do you include affordable housing requirements in your estimates?
A: Yes, we can provide separate cost breakdowns for market-rate and affordable housing units, accounting for specification differences and any grant funding implications. We understand Section 106 requirements and help optimize the affordable housing mix.
Q: Can you provide cost breakdowns by construction phase?
A: Yes, we regularly prepare cost breakdowns by construction phase, building block, or release phase. This is particularly useful for staged developments where different blocks are built at different times or for phased funding requirements.
Q: How do you handle varying ground conditions across a site?
A: We rely on the client’s ground investigation reports to assess foundation requirements. For sites with varying conditions, we zone the development and apply appropriate foundation solutions (piled, raft, strip footings) based on the geotechnical recommendations for each zone.
Q: What’s your fee structure for residential projects?
A: Fees vary based on project size, complexity, and timeline. As a rough guide: - Small development (10-30 units): £2,500-4,500 - Medium development (30-80 units): £4,500-8,000 - Large development (80-150 units): £8,000-14,000 - Major development (150+ units): £14,000-25,000
