Modern white house with large glass windows and a upper-floor dormer windows, situated in a garden with small trees and potted plants, under a clear blue sky.

Designed for context, planning and long-term value.

Working with London homes requires a careful balance of design ambition, planning strategy and technical understanding. Many properties sit within conservation areas, are subject to permitted development limitations, or require sensitive negotiation with neighbouring properties.

Atelier Khan specialises in London refurbishments and extensions that respond intelligently to these realities — combining architectural clarity with practical delivery.

Types of Extensions We Design & Deliver

We design and deliver a wide range of residential extensions, tailored to the existing building, local planning context and how the home is used.

Rear Extensions

Rear extensions are one of the most common ways to improve kitchen and living spaces in London homes. They require careful consideration of planning constraints, daylight, neighbouring amenity and material choice.

New modern house extension with large glass sliding doors revealing a dining room with six beige chairs around a table, white walls, and contemporary decor.

Common considerations:

  • Single-storey or double-storey options

  • Flat, mono-pitched or pitched roofs

  • Glazing strategy to maximise natural light

  • Relationship to garden and rear boundary

Side Return Extensions

Typically found in Victorian and Edwardian properties, side return extensions allow underused space to be incorporated into the main living area.

Modern kitchen with white and gray cabinetry, large central island, wooden bar stools, and views of a backyard with trees and patio furniture.

These projects often involve:

  • Structural alterations

  • Party wall considerations

  • Planning sensitivity in conservation areas

Double-Storey Extensions

Double-storey extensions provide significant additional accommodation but require a robust planning and structural strategy.

We assess:

  • Impact on neighbouring properties

  • Daylight and overshadowing

  • Massing and proportional balance

Loft & Roof Extensions

Loft extensions are a common route to additional space in London but are highly sensitive to planning controls.

A multi-story building with Victorian-style architecture, painted white, with decorative moldings and large windows, with a mansard roof and blue sky in the background.

We design:

  • Dormer extensions

  • Mansard roofs

  • Roof lifts where appropriate

All carefully shaped to respect street character and planning policy.

Refurbishments & Internal Works

Refurbishment projects can vary significantly in scope. We tailor our approach based on the level of intervention required.

Living room with a beige sofa, a red armchair with a blanket, a coffee table with decorative items, a window with shutters, a wall-mounted TV, and a dark accent wall.

Light Refurbishments

Ideal for improving flow, finishes and functionality without major structural changes.

Typical scope includes:

  • Internal reconfiguration

  • Kitchen and bathroom upgrades

  • Joinery and finishes

Heavy Refurbishments

Often undertaken alongside extensions, these projects involve substantial structural and layout changes.

They may include:

  • Structural alterations

  • Services upgrades

  • Reconfiguration across multiple floors
