Mac & Burg delivers substantial house extensions for homeowners looking to create more space, improve the way their property works and invest in the long-term quality of their home.

Extending an existing property brings different challenges from starting with a clear site. New construction needs to work with the original building, both structurally and visually, while the work itself needs to be carefully managed around the property and its surroundings.

Our hands-on approach and extensive construction experience allow us to manage these demands throughout the build. Around 90% of our work is kept in house, giving us greater control over workmanship, timescales and activity on site.

From large open-plan additions to multi-storey extensions and substantial structural alterations, we focus on building spaces that feel like a natural part of the home and are made to last.

Who We Work With

Every extension is shaped by the existing property and what its owners want to achieve. We work with homeowners and professional teams on substantial residential projects where the standard of construction and attention to detail are important.

Homeowners Planning Substantial Extensions

For homeowners who need considerably more space but do not want to move, an extension can transform both the size and layout of an existing property.

We can undertake major additions including expanded kitchen and dining areas, additional living space and new bedrooms across multiple storeys. Our team manages the construction work with close attention to the existing home and the quality of the finished addition.

Owners of Period and Character Properties

Extending an older property calls for particular care when introducing new construction alongside original features.

Materials, proportions and finishes can all influence how successfully the old and new parts of the property work together. Where appropriate, this can include sourcing complementary brickwork, roofing materials and finishes to create an addition that respects the character of the existing building.

Architects and Designers

We can work alongside architects, designers and other professionals to deliver approved designs on site.

Detailed residential schemes can involve significant structural alterations, steelwork, large areas of glazing and demanding architectural details. Our practical construction knowledge helps translate these plans into a finished extension while maintaining the design principles behind the project.

What We Build

Our extension work ranges from substantial additions to existing homes through to projects involving major changes to the layout and structure of a property. Our work can include:

- Large rear extensions
- Side extensions
- Double-storey extensions
- Wraparound extensions
- Open-plan kitchen and living additions
- Structural alterations and knock-throughs
- Garden rooms and connected living spaces
- Extensions incorporating large areas of glazing

Each project is built around the existing property, with close attention paid to how the new space connects with the original home.

Quality From the Ground Up

Mac & Burg was founded on a commitment to high-quality construction using skilled tradespeople, quality materials and modern building methods.

That same approach applies when working with an existing home. An extension should not feel like an afterthought. The structure, materials and finishes all need to work with the property while meeting the demands of modern living.

We also understand the importance of managing work responsibly when construction is taking place at someone’s home. Protecting existing areas, maintaining an organised site and reducing unnecessary disruption all form part of good project management.

Energy efficiency is another important part of our approach. We use modern construction methods and appropriate materials to help new spaces perform efficiently and remain comfortable throughout the year.

Above all, we build with longevity in mind. Our aim is to create an extension that works for the property now and continues to add useful, well-built space for years to come.

Our Approach to House Extensions

We follow a clear route through each stage of construction, adapting the work to the property, plans and scope of the extension.

01.
Initial Meeting and Site Review
We start by understanding the property, reviewing the proposed work and discussing what you want to achieve. Existing drawings or plans can be reviewed alongside the practical requirements of the build.
02.
Proposal
Once we understand the scope of the extension, we can establish the appropriate route for construction and discuss how the project can be delivered.
03.
Planning and Preparation
Before construction begins, the project is prepared for the work ahead. This can include coordinating materials, trades and site requirements around the agreed plans and programme.
0Groundworks and Structure
4.
Construction begins with the foundations and structural elements before progressing through the walls, floors, roof and any significant structural alterations required to connect the extension with the existing property.
05.
Internal Works
Once the main structure is complete and weatherproof, work progresses internally. The new and existing areas are brought together to create the layout and finish set out within the project plans.
06.
Completion
The final stage focuses on completing the outstanding work and preparing the new space for use, with attention paid to the details that influence the overall standard of the finished extension.

Experience Across Residential Construction

Our background in building homes from the ground up gives us a strong understanding of the structural and practical demands involved in substantial extension projects.

That experience is particularly useful where an extension involves significant alterations to the existing property. Rather than viewing the new addition in isolation, we look at how it connects with the structure, layout and character of the home as a whole.

Our practical knowledge also helps us work effectively alongside architects and other professionals, turning detailed plans into well-executed construction on site.
