Residential Design Tailored to Your Home

A successful extension should feel like a natural part of your property while providing the additional space you need.

We consider the existing architecture, proportions, daylight, garden relationship, neighbouring properties and practical requirements to develop designs that are both functional and visually considered.

Whether you are considering a single-storey rear extension, side extension, wraparound extension, two-storey extension or wider home renovation, we can help you explore the options available for your property.

House Extension Design Across Richmond upon Thames

Every home and site has different opportunities and constraints. The design of an extension needs to consider the existing building, garden, neighbouring properties, natural light, access, materials and the relevant planning requirements.

We provide house extension design services throughout the London Borough of Richmond upon Thames and surrounding areas, including:

  • Richmond – thoughtful extensions for period and modern homes, including rear, side and wraparound designs.

  • Kew – carefully considered additions that respond to the character of the property and surrounding streetscape.

  • Twickenham – practical residential extensions designed around your family's space, lifestyle and property.

  • Teddington – extensions that can improve kitchens, dining areas, family rooms, home offices and additional accommodation.

  • Hampton – bespoke extension designs developed around the proportions, layout and setting of each home.

  • Barnes – sensitive residential design for properties where the existing character and surrounding context are important considerations.

We also work with homeowners throughout the wider South West London area (Kingston upon Thames, Wembley, Chiswick, and more)

Planning for House Extensions in Richmond

Whether planning permission is required depends on the property and the proposed works. Some extensions may qualify under permitted development rights, subject to specific conditions and limitations.

Additional considerations may apply to properties within conservation areas, properties affected by an Article 4 Direction, listed buildings and other properties subject to planning restrictions.

Richmond upon Thames has 85 conservation areas, covering areas with particular architectural or historic character.

The council also provides specific guidance covering house extensions and external alterations, including rear extensions, side extensions, loft conversions and other residential alterations.

For this reason, it is sensible to consider the planning context at the beginning of your project rather than designing an extension without first understanding the relevant restrictions.

Extension Design in Conservation Areas

If your property is within a conservation area, the proposed extension needs to respond appropriately to the character and appearance of its surroundings.

This does not automatically prevent extensions or contemporary design. The appropriate approach depends on factors such as the scale and proportions of the addition, its relationship with the existing property, materials, roof form, boundaries, neighbouring buildings. Our design process takes these considerations into account when developing extension proposals for properties throughout the borough.

House Extensions

A well-designed extension can transform how a home feels and functions.

Depending on the property, this could include a:

  • Rear extension

  • Side-return extension

  • Wraparound extension

  • Single-storey extension

  • Two-storey extension

  • Kitchen extension

  • Family room extension

The appropriate planning route depends on the property and proposal. Permitted Development rights can allow certain householder projects without a full planning application, but specific limitations and conditions apply.
