More space. Properly designed, built and delivered.
A well-planned extension can transform the way a home works — creating more space, improving flow and allowing an existing property to adapt to the way you want to live.
Pace Construction delivers high-quality house extensions and property alterations across London, Surrey and Berkshire, combining practical construction expertise with professional project management from initial planning through to completion.
From rear and side extensions to larger wrap-around schemes, loft conversions and substantial structural alterations, we manage the construction process around the existing property, the architectural design and the requirements of the client.
Our focus is not simply on adding square metres. It is on creating new space that feels considered, properly constructed and genuinely connected to the home around it.
Designed around your home. Built around your requirements.
Every extension begins with an existing building, and that makes careful planning particularly important.
The structure, layout, access, neighbouring properties, planning constraints and condition of the existing home can all influence how an extension should be designed and delivered.
Pace works alongside homeowners, architects, structural engineers and other consultants to understand those conditions early and establish a practical construction strategy.
We consider how new and existing structures connect, how services need to be adapted, how the property will remain protected during construction and how the finished spaces should work together once the project is complete.
The objective is simple: create additional space that looks and feels like a considered part of the property — not an afterthought.
A complete extension service from planning to completion.
Pre-construction & buildability
Good extensions begin with a clear understanding of the existing property. Before construction starts, Pace can review drawings, structural information, specifications and proposed construction details from a practical delivery perspective.
This helps identify buildability considerations, access constraints, sequencing requirements and key decisions that may affect programme, cost or the finished result. Where required, we can work alongside architects, structural engineers and other professional consultants to help establish a clear route towards construction.
Structural alterations
Extensions frequently require significant changes to the existing building. Our work can include forming new openings, removing or adapting walls, installing structural steelwork, modifying floor layouts and coordinating temporary works where required.
These alterations are carefully sequenced and delivered in coordination with the structural design so that the new space can be opened into the existing property safely and effectively.
Extension construction
Once work begins, Pace can manage the complete construction process.
Our scope can include foundations and groundworks, structural walls and steelwork, roofing, insulation, windows and doors, mechanical and electrical services, plastering, internal finishes and external works.
We coordinate the individual packages as one construction programme, maintaining oversight of sequencing, quality and the interface between new and existing construction.
Loft conversions
Where extending outward is not practical, converting the roof space can provide valuable additional accommodation without sacrificing garden or external space.
Pace can deliver a range of loft conversion projects including Dormer, Mansard and Hip-to-Gable conversions, depending on the existing property, planning requirements and the space the client wants to create.
Loft spaces can be transformed into bedrooms, bathrooms, home offices, living areas or other functional accommodation while remaining carefully integrated with the existing home.
Completion & fit-out
The quality of an extension is often judged most closely where the new construction meets the existing property.
We coordinate the final stages of the project including plastering, joinery, electrical and plumbing finishes, kitchens, bathrooms, flooring, decorating and other agreed fit-out works.
Our objective is to hand over a completed space that feels resolved throughout — not simply a structurally finished extension.
Extensions that feel part of the original home.
The best extension projects improve more than the size of a property. They can change the relationship between rooms, bring more natural light into the home, create stronger connections with the garden and make existing spaces significantly more useful.
That may involve opening a traditional layout into a larger kitchen and living area, creating a new principal suite, introducing a dedicated home office or combining several previously disconnected spaces into one coherent part of the house.
Material selection, glazing, roof form, ceiling heights and structural detailing all influence how successfully the new construction relates to the existing building. Pace Construction approaches these decisions with the finished home in mind.
Whether the architectural intention is to blend the extension seamlessly with the original property or create a deliberately contemporary contrast, our role is to translate the design into construction with care and attention to detail.
The result should feel intentional from both inside and outside.
A professional approach to every stage of your extension.
Programme
Extension projects require careful sequencing because new construction often has to be coordinated around an existing and sometimes occupied property. We establish a realistic programme around structural works, weatherproofing, specialist packages, building services and internal finishes, monitoring progress throughout construction and responding early where adjustments are needed.
Procurement
Cost awareness
Extensions often involve existing conditions that are not completely visible until work begins. Our approach combines careful pre-construction review with clear communication during delivery, allowing cost and buildability implications to be discussed as information develops. Where practical alternatives can simplify construction or provide better value without compromising the intended result, we raise them openly with the client and design team.
Quality
Successful extension work depends heavily on the quality of the interfaces between old and new construction. We maintain oversight of structural work, weatherproofing, insulation, finishes and the detailed junctions that ultimately determine how well the completed extension performs and looks. Our team works with experienced trades and trusted specialists to maintain consistent standards throughout the project.
Communication
Having construction work undertaken at your home requires confidence in the team managing it. We believe in straightforward, regular communication around progress, forthcoming decisions and any issues requiring attention. Where clients remain in the property during part of the works, careful coordination and communication become even more important.
Flexible delivery. One standard of construction.
Clients approach extension projects at different stages. Some already have planning permission, architectural drawings, structural engineering information and a detailed specification ready for pricing and construction. Others require a construction partner capable of becoming involved earlier and helping establish the practical route from initial concept towards delivery.
Pace can support extension projects through a number of arrangements, including:
Main contracting
Client-Led Architectural Design
Structural Alteration Works
Complete Extension Construction
Project & Construction Management
Whatever the arrangement, our focus remains the same: experienced management, careful construction and professional delivery.
Built for homes that need more from their space.
An extension often involves considerably more than constructing a new room. Successful delivery can require multiple trades, structural interventions and changes throughout the existing property in order for the finished space to work properly.
Pace can coordinate a broad range of extension and alteration works, including:
Rear Extensions
Side Extensions
Wrap-Around Extensions
Loft Conversions
Dormer Conversions
Groundworks & Foundations
Brickwork & Blockwork
Roofing
Insulation & Building Fabric
Windows & External Doors
Mechanical & Electrical Services
Plumbing & Heating
Kitchens
Bathrooms
Bespoke Joinery
Flooring & Decorating
From the first idea to a finished extension.
Extending a home can be one of the most effective ways to create a property that works better without having to move.
But the strongest results come from looking at the project as a whole rather than treating the extension as an isolated addition.
Pace Construction provides homeowners with one accountable construction team capable of understanding the design, coordinating structural and specialist input and managing the practical realities of carrying out significant work to an existing property.
We take into account how the new space connects with the existing layout, how the home will function during construction and how the final finishes should come together once the project is complete.
Whether you are considering a contemporary rear extension, a substantial wrap-around scheme, additional accommodation within the loft or a wider programme of refurbishment and structural alterations, our focus is on delivering the project with care, professionalism and proper construction experience.
