House extensions have become one of the most practical ways to improve living space in London. Many homeowners prefer to extend rather than relocate. The right design can completely transform how a home looks, feels, and functions. This is where experienced Residential Architects play a vital role.
K&K Studio is known for delivering thoughtful, modern, and practical architectural solutions tailored to London homes. Their approach focuses on understanding how clients live, what they need from their space, and how a well-designed extension can improve daily life.
The popularity of Home Extensions in London
The older parts of London tend to have properties that offer very little room and space, and this situation is experienced by numerous families who have children that require additional space, or somewhere to set up a home office, or for open-plan living. Rather than the hassle of relocating and moving homes, extending the current property is a much more straightforward and cost effective option.
Extensions designed by professionals can do the following:
They can increase the space in the property that can be used
They can allow for improved ventilation and the circulation of air
They can increase the value of the property
They can result in the modernization of the design and layout of the property
They can create improved ways to enjoy the space and the areas that are located outside the property
However, in order to achieve these results from a home extension, a great deal of construction management, complex design, and the prioritization of a particular set of requirements, are needed to achieve the particular goals set by the home owner. Because of this, the majority of home owners decide to work with a Residential Architect.
What most Residential Architects do with Home Extensions Professionally
A Residential Architect aims to do more than just create a set of blueprints to demonstrate the various components of the extension. They take the time to understand the existing building, the current owner’s requirements, the state of the building, and the current planning restrictions.

K&K Studio’s Approach
K&K Studio’s design philosophy is based on timelessness, functionality, and simplicity. They focus on extensions that integrate with the original construction and provide a modern touch.
Designing with the Client in Mind
Every design process begins with a dialogue. The K&K Studio team spent time assessing the functionality and usage of a space by a homeowner in order to identify how value engineering the design will most significantly impact the space. This client-focused approach yields designs that capture the essence of the client’s needs.
Space Planning in London
K&K Studio reimagines the use of space by considering flow and the lifting of physical and psychological barriers through the use of circulated design. London is known to utilize every square meter, and K&K Studio combines the use of natural light to barriers in designing open plan kitchens, back extensions, and loft spaces to ones that are used every day.
Planning and Regulation Expertise
The planning and building regulation framework in London is complex and most London extensions fall into the categories of planning documentation. This includes residential conservation areas and other local authority planning and design guidelines. The experienced residential architects capture the essence of design while ensuring compliance and regulation are achieved.
Types of House Extensions
Rear Extensions
Rear extensions are one of the most popular choices for London homes. They often create open-plan kitchen and dining spaces that connect directly to the garden. With large glass doors or skylights, these extensions bring in natural light and create a more inviting atmosphere.
Side Return Extensions
Common in Victorian and Edwardian terraces, side return extensions utilize the narrow strip of land beside the property. Though small in size, they can significantly improve kitchen layouts and overall space efficiency.
Wraparound Extensions
A wraparound extension combines a rear and side extension to create a much larger ground-floor area. This approach is ideal for homeowners who want a spacious open-plan living environment.
Loft Conversions
When ground space is limited, extending upwards can be the best solution. Loft conversions add extra bedrooms, offices, or guest spaces without altering the property footprint.

House Extension Design Trends in London
Open Plan Living
Most modern families value flexible spaces as opposed to traditional compartmentalized layouts. Their ideal home encourages interaction between cooking, dining, and other social activities.
Natural Illumination
Design features such as large windows, skylights and sliding glass doors help make spaces feel larger, creating an open and welcoming environment.
Sustainable Design
There is growing demand and supply for sustainably harvested timber and other sustainable design materials, as well as energy-efficient glass and insulation.
Seamless Indoor-Outdoor Living
Sliding and folding doors that lead to the garden extend the living area outdoors.
Planning Permission and Building Regulations
Extensions to existing homes sometimes do not require a formal planning application and can be developed under the existing owner's Permitted Development Rights. However, the type of property, the area in which the property is situated, and the size of the proposed extension can affect which rules apply.
