Design & Build Contractors Belgravia SW1: NU Projects Prime Central London Specialists
- May 13
- 6 min read
Belgravia property does not operate in isolation.
A single residential project can involve a private client, architect, interior designer, surveyor, buying agent, property manager, planning consultant, heritage adviser, family office, MEP consultant, structural engineer and estate manager.
The challenge is not finding more people around the table.
The challenge is making the project work.
NU Projects exists for that point.
We are a design-led architecture and build company working across prime and super-prime London homes. Founded by Nick Jeffries, NU has spent more than 15 years delivering high-quality residential projects across London, with a particular focus on Belgravia, Prime Central London and the addresses where stucco-fronted perfection and white-glove delivery set the standard.
Our work spans architecture, interior design, construction, structural works, basements, MEP, bespoke joinery, finishing, project management, aftercare and full design and build delivery.
The purpose is simple.
One team. One contract. One standard.
Why professional advisers need the right delivery partner
For many property professionals, the construction stage is where risk increases.
A buying agent may help a client acquire the right home, only for the refurbishment cost to become unclear after completion.
An architect may secure a strong design, but then see that design weakened through poor site execution.
An interior designer may specify beautiful finishes, joinery and lighting, only for coordination to fail once trades arrive.
A property manager may be asked to recommend a contractor for a high-value home, apartment or managed building, knowing that the wrong team can create noise, disruption, complaints and unnecessary risk.
A family office may need discreet, reliable property support for a client who expects clear reporting, controlled access and no drama.
This is where NU Projects adds value.
We help professional advisers support their clients before, during and after residential property works.
Supporting clients before purchase
The best time to understand a property is often before a client commits.
For buying agents, property search advisers, private client lawyers, mortgage advisers and family offices, early design and build advice can help a client make better decisions.
NU can review a property and advise on:
Refurbishment potential, Layout improvement, Structural opportunity, Basement or extension potential, Planning and heritage considerations, MEP risk, Build cost direction, Programme implications, Procurement and delivery route, Likely disruption and access challenges
This gives the client a clearer view of what the property can become, what it may cost and how long it may take.
It also helps the adviser protect the client relationship by introducing practical property intelligence before a purchase becomes a project.
Supporting architects and interior designers
Architects and interior designers need a contractor who respects the design.
That means understanding drawings, specifications, proportions, materials, interfaces, sequencing, samples, detailing and the client’s expectations.
NU works with professional design teams where the brief needs proper translation from concept to site.
Our role is not to replace the architect or designer.
Our role is to support them.
We help protect design intent through buildability advice, cost planning, procurement control, programme management, technical coordination, quality site management and proper communication.
This is particularly important in prime residential work, where a design can be weakened by small decisions on site.
A shadow gap, stone junction, lighting position, door margin, brass detail, timber grain or paint finish may look minor in isolation.
Together, they define the standard of the home.
Supporting property managers and estate managers
Prime homes and managed buildings need more than trade attendance.
They need careful access, clean working, resident sensitivity, building management coordination, clear reporting, proper sequencing and respect for finished interiors.
NU supports property managers, estate managers, managing agents and building teams with:
Private apartment refurbishments, Common parts upgrades, MEP works, and coordinationPlant room and services works, Leak repairs and defect resolution, Heating, hot water and electrical support, Bespoke joinery and finishing works, Structural alterations, Resident-sensitive working methods, Programme, procurement and cost control, Aftercare and maintenance
In high-value residential buildings, the work is never just about construction.
It is about protecting the property, respecting residents, controlling disruption and keeping everyone informed.
Supporting planning and heritage consultants
Planning consent is only one stage of the process.
The next challenge is turning permission into a buildable, costed and properly managed project.
NU supports planning consultants, heritage consultants and client advisers by helping clients understand how an approved or proposed scheme can move into delivery.
That includes:
Buildability review, Cost planning, Programme planning, Structural coordination, Basement and lower-ground works, Listed and period property refurbishment, Conservation-sensitive detailing, MEP coordination, Procurement advice, Full project delivery
Prime London homes often involve period fabric, conservation areas, party walls, access limitations, basement constraints, planning conditions and neighbour sensitivity.
The right build partner needs to understand those risks before site starts.
Supporting family offices and private client advisers
Private clients often rely on trusted advisers to manage more than finance.
Property is part of that responsibility.
A client may be acquiring a London residence, upgrading a family home, refurbishing a pied-à-terre, improving a rental property or resolving defects in a high-value apartment.
For family offices, wealth advisers and private client teams, NU provides a discreet route to trusted residential project support.
We understand the importance of:
Confidentiality, Direct communication, Cost visibility, Programme control, Professional reporting, Respect for finished homes, Clear accountability, Aftercare beyond completion
Our role is not to interfere with the adviser’s relationship.
Our role is to support it.
Supporting super-prime buildings and mansion blocks
London’s most valuable residential buildings require a particular type of contractor.
Access is controlled.
Common parts must be protected.
Residents must be respected.
Noise, dust, working hours, lift use, deliveries, waste removal, approvals, building rules and concierge communication all need to be managed properly.
NU supports super-prime residential buildings, mansion blocks, private estates and managed residences where works require a careful, professional and accountable team.
This may include apartment refurbishments, MEP works, joinery, finishing, technical upgrades, plant room works, common parts improvements and aftercare.
The standard is not just the finished work.
The standard is how the work is delivered.
Why one accountable team matters
Many residential projects suffer because responsibility is split.
The architect designs.
The interior designer specifies.
The engineer advises.
The contractor prices.
The subcontractors interpret.
The client tries to understand who is responsible.
NU’s model is different.
Architecture, interior design, build, MEP coordination, bespoke joinery, project management and cost control sit inside one delivery structure.
That means fewer gaps, clearer responsibility and a stronger route from idea to completion.
For private clients and the professionals advising them, this matters.
It means the conversation about design, cost, programme and buildability can happen earlier.
It means problems are identified before they become expensive.
It means the client has one accountable team controlling the project.
Where NU Projects works

MayfairKnightsbridgeBelgraviaChelseaKensingtonSouth KensingtonNotting HillHolland ParkFulhamParsons GreenHammersmithChiswickRichmondBarnesSt John’s WoodHampsteadMaryleboneBatterseaWestminsterWimbledonWider prime London by arrangement
Each address has its own demands.
A Chelsea townhouse is different from a Kensington apartment.
A Hampstead family home is different from a Belgravia mansion block.
A Notting Hill refurbishment is different from a Mayfair pied-à-terre.
The standard must stay consistent.
The approach must adapt to the property.
