Design and build company in London. Designers, a quantity surveyor and builders, under one contract.
A successful design and build project is not about speed or visuals. It is about process control, early decision making, and clear accountability from day one.
This covers the end to end design and build process used by NU Projects. It runs from first conversation through to handover and aftercare. It explains how premium residential projects are delivered. The market is London’s prime and super prime.
1. Initial consultation and brief
Every project begins with clarity.
The first stage focuses on:
- Understanding how the property is used
- Identifying priorities, constraints, and risks
- Establishing realistic budget expectations
- Confirming whether design and build is the right route
NU Projects uses this stage to qualify suitability on both sides. Not every project is a fit, and that honesty protects outcomes later.
2. Feasibility and early budget guidance
Before design progresses, feasibility is tested.
This includes:
- Initial layout strategy
- Planning context and constraints
- Structural implications
- High level budget ranges
NU Projects provides early cost guidance based on real project data. It does not use online calculators or generic rates. This allows informed decisions before time and fees escalate.
3. Concept design and spatial strategy
Once feasibility is confirmed, concept design begins.
This stage focuses on:
- Overall layout and flow
- Massing and spatial proportions
- Natural light strategy
- Alignment with planning policy
At NU Projects, concept design is developed with construction in mind. This ensures ideas can be delivered without compromise or redesign later.
4. Planning and statutory approvals
Planning is treated as a strategic phase, not an administrative one.
This includes:
- Pre application advice where appropriate
- Coordination with planners and consultants
- Managing conservation or listed building considerations
- Clear timelines and expectations
NU Projects manages planning alongside design development to avoid unnecessary delays and rework.
5. Technical design and pre construction coordination
This is the most critical stage in the process.
It includes:
- Detailed architectural drawings
- Structural engineering coordination
- MEP design integration
- Fire, acoustic, and thermal strategy
- Building Control engagement
NU Projects resolves these elements before site start. This significantly reduces variations, delays, and cost risk during construction.
6. Scope of works, and locking the cost
Once design is coordinated, scope is fixed.
This stage delivers:
- Detailed scope of works
- Trade packages aligned to drawings
- Clear inclusions and exclusions
- Finalised cost position
NU Projects prioritises cost certainty at this point. This allows clients to proceed with confidence before mobilisation.
7. Construction and site management
Construction is controlled, structured, and sequenced.
Key principles include:
- Specialist trades for specialist work
- Programme led delivery
- Regular quality inspections
- Clear communication channels
NU Projects manages construction with senior oversight. This ensures detail and finish align with the approved design.
8. Client communication and decisions
Throughout the build, communication remains consistent.
Clients receive:
- Regular progress updates
- Advanced notice of decisions required
- Visibility on programme and cost
- Early identification of issues
This structured approach avoids last minute pressure and maintains trust on complex projects.
9. Practical completion and handover
Completion is not a single event.
It includes:
- Detailed snagging
- Building Control sign off
- operating and maintenance manuals and documentation
- Client walkthroughs
NU Projects ensures the property is fully documented. It is ready for occupation, not simply finished.
10. Aftercare and long term support
The process continues beyond handover.
Aftercare includes:
- Defects management
- Ongoing support
- Trade follow ups where required
NU Projects views aftercare as part of delivery, not an optional extra.
Why this process matters
Design and build only works when the process is disciplined.
That structure is how NU Projects holds quality, cost and the client experience steady. This applies across prime and super prime residential work in London.
