Find Out MoreWhen planning a renovation or extension, it’s helpful to understand how the overall investment is typically distributed. While every project differs, most budgets are allocated across several key areas. Below is a guide to how investment is commonly structured within a well-managed, high-quality project.
Typically 30–40% of the overall investment
This includes foundations, brickwork, roofing, structural steel, insulation, drainage alterations and compliance with current building regulations. These elements form the backbone of your project. Much of this work sits behind the walls and beneath the floor, but it is critical in ensuring your home is structurally sound, energy efficient and built to last.
Typically 10–20%
Modern extensions often incorporate large glazing systems, roof lanterns or Bi-fold or sliding doors. These features significantly influence both the aesthetic and performance of the space. Specification, size and supplier choice can all affect this portion of the budget.
Typically 20–35%
For projects involving new kitchens, bathrooms or fitted bedrooms, cabinetry and internal finishes represent a substantial portion of the investment.
This includes:
Cabinetry and internal configurations
Worktops
Sanitaryware and fixtures
Tiling
Flooring
Lighting
Specification choices play a key role here. From high-quality manufactured cabinetry to bespoke joinery, from standard fittings to statement pieces, these decisions shape both the final look and overall cost.
Typically 15–25%
Skilled workmanship is essential to achieving a high-quality finish that performs well long-term. Unlike many building companies that rely solely on subcontracted labour, we use trusted in-house and long-standing specialist trades wherever possible. This ensures consistency, accountability and a higher standard of finish across plumbing, electrical work, tiling, joinery and decoration.
By working with experienced professionals who understand our standards and processes, we reduce errors, improve coordination and maintain quality throughout the build. The result is not just a beautiful finish, but a durable one.
Typically 10–15%
A well-delivered renovation is about far more than construction alone.
This portion of the investment covers:
Architectural and design development
Technical drawings and structural coordination
Planning and building control liaison
Detailed scheduling
On-site supervision
Dedicated project management
Our structured approach means you have a single point of contact overseeing every stage. We coordinate trades, manage timelines, control quality and ensure communication remains clear throughout.
In practical terms, this means you don’t need to manage multiple contractors, chase updates or resolve scheduling conflicts. The responsibility sits with us. This level of management significantly reduces stress, minimises disruption and protects your overall investment.
Variable
For most residential projects, VAT forms part of the total investment. Planning applications, structural calculations and building control fees may also apply depending on scope.
While it’s natural to focus on the visible elements of a project, a substantial part of the budget ensures your home is structurally sound, professionally managed and finished to a high standard. A well-balanced investment considers not only how the space looks on completion, but how it performs and endures for years to come.
To ensure we can deliver the level of design, workmanship and project management we’re known for, we operate with minimum investment levels depending on the type of project. These are not arbitrary figures, they reflect the level of professional input, coordination and quality required to deliver a well-managed result.
Bathrooms: from £18,000
Kitchens: from £30,000
Extensions: from £60,000
Larger remodels and full home renovations will naturally sit above these levels depending on scope and complexity. As a design and build company, every project we undertake includes:
Professional design input
Detailed specification and planning
Coordinated, trusted trades
Dedicated project management
Building control and compliance management
We don’t offer supply-only services or partial installations. Our role is to manage your project fully, from initial concept through to completion, ensuring clarity, accountability and quality at every stage.
For projects outside these investment levels, we may not be the right fit, and we believe it’s far better to be transparent about that from the outset. If you’re planning a renovation, kitchen, bathroom or extension within (or above) these ranges and are looking for a structured, professionally managed experience, we’d be delighted to explore your ideas with you.
“Adamsons designed and installed our new bathroom and were meticulous about ensuring we were never left without a toilet overnight. Their staff were consistently professional, well-organised and strong on project management, design expertise and advice. They were consistently polite, tidy and reliable throughout, and the after-sales service has been excellent. A real pleasure to work with from start to finish.”
Choosing the right company for your renovation or extension is about more than budget alone. It’s about expectations, communication and the type of experience you want throughout the process.
We tend to be the right fit for homeowners who:
Want a fully managed, start-to-finish service
Value professional design input and careful planning
Prefer fixed pricing and clear documentation
Appreciate structured timelines and regular communication
Are investing in their home for the long term, not just a quick upgrade
Our clients often tell us they chose us because they wanted clarity, accountability and a team they could trust to manage every moving part.
We may not be the best fit if:
You’re primarily seeking the lowest possible quote
You’d prefer to coordinate individual trades yourself
You’re looking for small repair or maintenance works
Budget expectations are significantly below the ranges outlined above
And that’s perfectly fine: different projects require different approaches.
