What does £1 million buy you in a prime London home renovation?

A £1 million renovation budget can transform a prime London property, but the number alone does not define the result. The size and condition of the home, the amount of structural change, the services strategy, the specification and the complexity of access all determine what that investment can achieve.

For one client, the budget may create a complete apartment transformation. For another, it may fund a carefully prioritised refurbishment of a larger townhouse. NU Projects begins by aligning ambition, property and investment so every major decision supports the finished home.

What a £1 million renovation may include

• Architecture, interior design and coordinated technical information.
• Structural alterations and carefully planned changes to layout.
• New heating, cooling, ventilation, lighting and electrical systems.
• High quality kitchens, bathrooms, natural stone and specialist finishes.
• Bespoke joinery, fitted furniture and considered storage.
• Decoration, flooring, ironmongery and final styling.
• Quantity surveying, project management and construction delivery.

The precise balance is project specific. A listed townhouse, a lateral apartment and a modern penthouse require very different design and delivery strategies. The cost plan must therefore be built around the actual property rather than a generic luxury allowance.

Where should the investment go first?

The projects that hold their value invest first in the elements that protect the building and are difficult to alter later. Structure, waterproofing, acoustic performance, heating, cooling, ventilation, power and lighting infrastructure form the foundation. They may be less visible than marble or joinery, but they determine how well the home performs.

Once the technical base is secure, the budget can be concentrated on the rooms and details that create the greatest daily value. Kitchens, principal suites, living spaces and bespoke storage frequently deserve priority because they combine function, comfort and visual impact.

What can quickly stretch the budget?

• Basement excavation, complex temporary works or extensive structural alteration.
• Listed building requirements, conservation work and restoration of original fabric.
• Air conditioning, sophisticated controls, audio visual systems and specialist security.
• Imported stone, highly bespoke kitchens, specialist plasterwork and extensive joinery.
• Restricted access, apartment management rules, limited working hours and demanding logistics.
• Late changes after manufacture or construction has begun.

A considered example

Imagine a prime London apartment where the structure is largely retained. The investment can be directed towards a complete services upgrade, a refined kitchen, beautifully detailed bathrooms, bespoke joinery, lighting, flooring and decoration. In a townhouse requiring major steelwork, façade repairs and extensive restoration, more of the same budget must support the building before the interiors.

Neither approach is better. The right answer is the one that respects the property and the client’s priorities. NU Projects makes those choices visible early, allowing the team to protect the details that matter and remove expenditure that adds little value.

How NU Projects protects a major renovation budget

NU combines architecture, interior design, quantity surveying, project management and construction. Cost is reviewed while the design develops, procurement is planned around lead times, and technical coordination happens before site decisions become expensive.

• Define the brief and non negotiable priorities.
• Investigate the property and identify risks.
• Coordinate design, services and structural requirements.
• Measure the scope and test realistic allowances.
• Review value without diluting the design intent.
• Track decisions, procurement and changes through construction.

Frequently asked questions

Is £1 million enough for a prime London renovation?

It can be, but the answer depends on the scope. A carefully designed apartment can be finished throughout on that budget, while a larger property with structural or heritage work will need the money allocated very differently.

Should professional fees sit inside the budget?

Yes, they should be visible in the overall investment plan. Hidden or missing fees create a misleading picture of affordability.

Can value engineering protect quality?

Yes. Good value engineering removes cost that does not support the brief while protecting proportion, function, craftsmanship and the most important materials.
