House Extension Architect in London

Renowned Extension Architects Near You

London is one of the most densely built cities in the world, making a well-designed residential space a constant priority for homeowners. With property prices continuing to rise and moving to a larger home becoming increasingly impractical, extending your current property has become a popular and cost-effective solution.

Krystal Architecture is a trusted house extension architect in London, offering comprehensive architectural services tailored to residential projects of all scales. Our team brings deep knowledge of local planning policies, permitted development rights, and building regulations across London boroughs. From initial concept through to the submission of the final extension plans, we guide you clearly and efficiently at every stage of your project.

We understand that every home and every homeowner is different. That is why our architects take the time to understand your vision, your budget, and the specific constraints of your property before proposing any design solutions. Our goal is to deliver a result that is both architecturally unique and practically suited to your everyday needs.

Extension Projects We Undertake

At Krystal Architecture, we specialise in designing all types of home extensions with expert care and precision. By collaborating with the homeowners, the different types of house extensions we design are:

Single Storey Extensions: One of practical ways to increase your ground floor area is by adding a kitchen, dining space, or a lounge without changing the existing layout.

Two-Storey Extensions: This extension offers maximum increase in the usable floor space. It is ideal for growing families who need extra living space and additional bedrooms.

Rear Extensions: Rear extensions are among the most common extension projects in London. This seamlessly connects your back garden space with your indoor living space.

Side Return Extensions: A side return extension makes use of the narrow alleyway typically found alongside terraced and semi-detached homes.

Wraparound Extensions: A wraparound extension combines a rear and side return extension into one cohesive design, providing the largest possible increase in ground floor space.
