Design & build in Chelsea

MVV is a high-end design and build contractor working throughout Chelsea, from the garden squares and terraces of SW3 to the mansion flats and townhouses around SW5. We help homeowners reshape period properties for modern living, whether that means a sensitive refurbishment, a considered extension, a loft conversion or a complete redesign of how a home works day to day. Chelsea is one of London's most architecturally rich neighbourhoods, and that brings both opportunity and constraint. Much of the housing sits within conservation areas, and a good number of properties are listed or sit on tightly packed streets where access and neighbours need careful thought. We bring design and construction together under one roof so that the brief, the detail and the build all hold together from first sketch to final handover.
Chelsea housing and what it needs
Chelsea homes are typically Victorian and Georgian townhouses, period conversions and mansion flats, often with original features that are worth protecting and proportions that reward careful work. Many sit within conservation areas, and listed buildings are common, so changes need to respect the existing fabric while still delivering the space, light and comfort a modern household expects.
The practical challenges tend to be consistent: narrow frontages, shared party walls, restricted access for deliveries, and the need to keep disruption to neighbours to a minimum. We plan for these realities from the outset, taking time to understand the structure, the local context and how you want to live in the finished home before any work begins.
The MVV approach
As a design and build contractor, we manage the whole process, from initial design and technical drawings through to construction, joinery and finishing. That single point of responsibility keeps decisions joined up and helps avoid the gaps that appear when design and build are handled separately.
Our work in Chelsea spans full home refurbishments, house extensions, loft conversions, listed building and period property work, bespoke joinery and kitchen renovations. We carry public liability cover of up to 10 million pounds, and we work to a standard of finish suited to high-end period homes, with attention paid to the details that make a difference, from flooring and cabinetry to bathrooms and bespoke built-in elements.
Featured Chelsea project: Margaretta Terrace
At Margaretta Terrace in SW3, we carried out the design and build of a Victorian townhouse in the heart of Chelsea, combining classic character with modern luxury. The project included marble bathrooms, bespoke chimneys, herringbone flooring and a bespoke deep-blue library shared with the living space.
It is a good example of how we approach period homes in the area: keeping the charm that makes a Chelsea house distinctive while bringing the layout, materials and finishes up to a contemporary standard. We have also delivered projects nearby at Bolton Gardens in SW5, a two-bedroom flat refurbishment with strategic layout changes, bespoke joinery and two renovated bathrooms, and Lexham Gardens in SW5.

Frequently asked questions
- Do I need planning permission or listed building consent in Chelsea?
- It depends on the property and the work. Many Chelsea homes sit within conservation areas, and a good number are listed, which means external changes and some internal alterations can require consent. Smaller works may fall under permitted development, though this is often restricted in conservation areas. As a design and build contractor we assess this early and factor any necessary applications into the plan, so there are no surprises once work is under way.
- How do conservation areas affect what I can do?
- Conservation area status is intended to protect the character of an area, so it tends to focus on what is visible and on preserving original features and materials. In practice that can shape choices around extensions, roof alterations for loft conversions, windows and external finishes. Internally there is often more scope, particularly for refurbishments and layout changes, and we design with both the rules and the original fabric of the building in mind.
- How long does a project in Chelsea usually take?
- Timelines vary with the size and complexity of the work, the condition of the property and whether consents are needed. A focused refurbishment or kitchen renovation is shorter than a full design and build of a townhouse or a loft conversion. Once we have understood your brief and surveyed the property, we set out a realistic programme so you know what to expect at each stage.
- How do you manage disruption to my home and neighbours?
- Chelsea streets are often narrow and closely built, so we plan access, deliveries and working hours carefully and keep the site clean and considerate throughout. Party wall matters with adjoining owners are handled in good time, and we keep you informed as work progresses so that life around the project stays as manageable as possible.
