House Extensions in Wellington

Rock Projects delivers bespoke, space-creating house extensions across Wellington, Taunton, and the surrounding areas. We undertake architect-led residential extensions for private clients and estates known for comfortable living and increased market value.

Expanding South West Properties with Architect-Led Construction

Rock Projects (SW) Ltd is widely regarded for its support of private homeowners, landowners, and professional teams through carefully managed residential construction. With decades of experience, our work is defined by disciplined project control, technical competence, and a clear understanding of how extensions must integrate structurally, architecturally, and functionally with an existing property.

We undertake extensions to a wide range of property types throughout Wellington, Taunton, and the surrounding areas, from traditional family homes to large private residences, rural properties, and period buildings. Whether the objective is to increase living space, reconfigure internal layouts, or modernise a property while retaining its character, our role is to deliver an extension that enhances both usability and long-term value.

House extensions are frequently undertaken alongside broader improvement works, such as kitchen extensions, internal reconfigurations, or structural upgrades, allowing you to achieve a cohesive, considered transformation rather than incremental change. As our gallery shows, we deliver results that consistently exceed our valued clients’ expectations.

Types of Property Extensions We Deliver

Our property extensions are designed and constructed to suit each client’s individual requirements. We regularly deliver:

Single Storey Extensions

Often used to create open-plan kitchen, dining, and living areas, a single storey extension is particularly effective where improved flow and connection to external space are required.

Double Storey Extensions

Suitable for properties requiring additional bedrooms, bathrooms, or reception spaces, our double storey extensions allow significant increases in floor area while maintaining a balanced external appearance.

Side, Rear and Wraparound Extensions

Side and rear additions are designed to complement the existing structure while improving spatial efficiency and functionality. Combining the two into a wraparound extension can dramatically increase internal space and allow for substantial reconfiguration of ground-floor layouts.

Extensions to Larger Properties and Estates

Including wing extensions, annexe accommodation, and sensitive additions to period homes, manor houses, and rural properties.

Each extension we complete in Wellington and Taunton is carefully planned to respect the proportions, materials, and architectural language of the existing building, ensuring a coherent final result.

When a House Extension Becomes the Right Solution

Clients typically consider a house extension when existing space no longer meets their needs or no longer reflects how the property is used. Common drivers include:

Insufficient space for changing family or lifestyle requirements
The need for improved layouts rather than additional rooms alone
A desire to modernise and rationalise older properties
The wish to increase property value without relocating
Requirements for guest accommodation or secondary living spaces

Rather than viewing an extension purely as additional square footage, we approach it as a strategic enhancement to the property as a whole.

What Could a House Extension Be Used For?

House extensions offer exceptional flexibility and can be tailored to a wide range of residential uses. Across projects delivered in Wellington, Taunton, and the surrounding areas, our clients have used extensions to create:

Architect-Led Kitchen and Dining Spaces – Including open-plan kitchens, kitchen–dining–living environments, island kitchens, pantries, and larders designed for both everyday use and entertaining.
Formal and Informal Living Areas – Additional reception rooms, family rooms, or garden-facing living spaces that improve circulation and natural light.
Bedroom Suites and Private Accommodation – Including principal bedroom suites, guest bedrooms, and self-contained accommodation within the main dwelling.
Home Offices and Professional Workspaces – Dedicated office environments designed to support long-term remote or hybrid working.
Annexes and Secondary Living Areas – Suitable for extended family, guests, or independent living while remaining connected to the main property.
Leisure and Lifestyle Spaces – Including libraries, studios, hobby rooms, home gyms, or media rooms.
Sensitive Extensions to Period and Heritage Properties – Where careful detailing and proportion are essential to preserve character while improving usability.

Each use is considered in relation to structural feasibility, planning context, and how the new space will interact with the existing home.

Managing the House Extension Process

Delivering a successful single storey, double storey, or wraparound extension requires careful coordination across design, construction, and regulatory stages. Rock Projects’ role as builder is to provide clarity and control throughout the process, including:

Liaison with architects and consultants
Planning permission and building regulations coordination
Groundworks, drainage, and structural works
Superstructure construction and weatherproofing
Services installation and internal fit-out
Quality control, inspections, and final handover

This structured approach ensures that extensions are delivered efficiently, compliantly, and to a consistently high standard.

FAQs – House Extensions

Do house extensions require planning permission?

Some house extensions may be completed under permitted development rights, while others will require a full planning application. This depends on factors such as the size and position of the extension, the type of property, previous alterations, and any site constraints (for example, conservation areas around Wellington or Taunton, or listed status). As part of the early-stage discussion, we can advise on the typical route and work alongside architects or planning consultants to ensure the correct approvals are secured before construction begins.

How do you ensure the extension blends with the existing property?

A successful extension must integrate structurally, visually, and practically with the original building. We work to the approved design and specification, paying close attention to rooflines, proportions, external materials, and junction detailing. Internally, we focus on flow, natural light, and continuity of finishes, ensuring the extension reads as a deliberate part of the home rather than an addition. Where South West properties are of period or heritage character, we take particular care to preserve their architectural integrity.

How long does a typical house extension take to build?

Timescales vary according to extension type, complexity, site access, and the level of internal fit-out. A single storey extension and a more complex double storey scheme have very different programmes, particularly where structural alterations and extensive internal reconfiguration are involved. Once the scope is defined and design information is available, we provide a structured programme and maintain clear communication throughout the build to support predictable delivery.

Do you undertake larger, architect-led extensions for high-value properties?

We deliver extensions ranging from straightforward additions to architect-led schemes for larger properties, including substantial side, rear, and wraparound extensions, as well as projects involving wing additions, annexe accommodation, and sensitive alterations to period homes.
