If an extension isn’t the right fit
Not every property suits an extension. In that case, a loft conversion is worth considering, because many homes have more untapped space than their owners realise. We also carry out kitchens, bathrooms, roofing and refurbishments, so we can advise on the right approach for your home.

Designed and project managed for you
After the survey, we create a design that reflects the style you want, from mapping out the interior layout to choosing architectural details that match the existing house. We can design single or double-storey extensions for almost any use:
- Kitchen extensions
- An office or study
- Extra living space
- A children’s playroom
- An additional bedroom
We take care of obtaining planning permission and project manage the whole job. We keep strict quality control throughout and only sign off each stage once you are satisfied. With all the trades under one roof, there is no need to bring in anyone else.
Start to finish, or alongside your builders
We can take your extension from start to finish, or work alongside builders and carpenters you already have in place. Either way, we offer a range of finishes and styles and keep you informed at every stage. We work for fellow builders and contractors as well as homeowners, and we are happy to supply references.
House extensions across Winchester and nearby
Extending a Winchester home often means working within a conservation area or the South Downs National Park, where permitted development rights are reduced and the prior approval route for larger rear extensions is not available. Period terraces in Fulflood, Hyde and St Cross usually suit a sympathetic single-storey rear extension, while homes in the surrounding villages tend to have larger plots. We design extensions that match the original brick, roof and windows, and help with the application.
Also covering
- Alresford
- In Alresford we design extensions to sit behind the street frontage, keeping the Georgian character of the town centre intact.
- Twyford
- Village homes in Twyford often have generous gardens, which can make a single-storey rear or side extension the simplest way to add space.
- Sparsholt
- On Sparsholt's larger rural plots, a kitchen or garden-room extension can be planned to make the most of views over the countryside.
- Bishop’s Waltham
- For Bishop's Waltham homes in or near the conservation area, we choose bricks and roof materials that match what is already there.
- Swanmore
- Swanmore's newer houses are often extended at the side or rear to create a bigger kitchen and family room.
- Wickham
- Extensions to Wickham's older cottages and townhouses need a design that respects the conservation area, which we take into account from the first sketch.
- Durley
- Rural Durley properties may need a site survey of drainage and ground conditions before an extension's foundations can be designed.
- Denmead
- Denmead has plenty of 20th-century semis and detached homes where a single-storey rear extension is a common way to gain a kitchen-diner.
A typical house extension project in Weeke, Winchester
- The home
- Weeke has many detached suburban houses with long rear gardens and room to build out at the back.
- What's usually wanted
- Families often want a larger kitchen and family room that opens onto the garden.
- How we'd approach it
- We design a single-storey rear extension in materials that match the house, and check whether it can go ahead under permitted development or needs an application to Winchester City Council. Roof lights or a lantern are usually added to keep the middle of the house bright.
- The result
- A big, light kitchen and living space with direct access to the garden.
