Services Offered

Extensions

Extensions in Bristol

Extensions add new space to your home by expanding its existing footprint, whether through rear, side, or double-story additions. They are a popular way to increase living areas, create open-plan layouts, or add extra rooms without moving. Extensions seamlessly blend with your current property, enhancing both its functionality and value while allowing for customised design features.

Wrap around Extension

Refurbishments in Bristol

Refurbishments involve updating and improving your home by modernising kitchens, bathrooms, and finishes, enhancing layouts, and making internal structural alterations. This process revitalises your property, addressing wear and tear while increasing comfort, energy efficiency, and functionality. Refurbishments offer a cost-effective way to transform your living space without the need for extensive external structural changes.

Side Extension

Outbuildings in Bristol

Outbuildings are versatile structures that can be added to your property, such as garden offices, workshops, or studios. Typically built separately from the main house, they provide additional space without the need for major alterations to your home. Outbuildings are popular for their flexibility, allowing homeowners to create functional, customised spaces that enhance the property's overall utility and value.

Double Storey Extension

New Builds in Bristol

Small scale new build dwelling planning options include side garden plots, which utilize adjacent space next to an existing property; backlands plots, which develop land behind existing properties and are accessed via a shared driveway; and infill plots, which focus on constructing homes within vacant or underused urban spaces. Obtaining planning permission for a new dwelling unlocks the full potential of land, typically increasing its value to 40% of the completed house's sales price.

Rear Extension

Loft Conversions in Bristol

Loft conversions transform unused attic space into functional living areas, such as bedrooms, offices, or playrooms. This type of conversion is an excellent way to add value and square footage to your home without altering its footprint. Loft conversions are popular for their ability to maximise space, offering a cost-effective solution to growing families or those needing extra room.

Flat-Conversions

Flat Conversions in Bristol

Flat conversions involve transforming a single property into multiple self-contained flats, making efficient use of existing space. This process is ideal for larger homes or period properties, maximising rental income, or accommodating extended family. Flat conversions can significantly increase a property's value while offering a practical solution to the growing demand for housing in urban areas.
