House Extensions

Whether you are just looking for a practical way to create more room in your home or wish to create new and exciting spaces, we are highly experienced in delivering house extension projects regardless of size or budget.

From a small addition to a substantial transformation, we can expertly guide you through the process from inception to completion.

We have a passion for design which is reflective in our work. We care deeply about our projects and ensure, by way of detailed and robust technical drawings, quality of design is carried through into the finished built product.

New Build Homes

Coogan Architects have designed many new build homes and can advise on site choice and layout, budget preparation, design options, planning guidance and restrictions, material and construction options including methods of sustainability.

Internal Alterations

Sometimes, all it takes is the reconfiguration of space to produce the optimum layout. From the removal of walls to create open-plan living, introduction of additional natural daylight or views/access to the garden; all can be created or enhanced by simple or more substantial alterations.

Attic Conversions

An existing roof space can be a useful and cost effective way of creating additional space within your home. We can help you identify whether your attic can easily be converted and creatively advise on potential layouts, ideal stair locations and the potential use of rooflights or dormer windows.

Garage Conversions

Garages are less likely to be used to park cars and many homeowners feel this additional space is best suited to create cost-effective habitable accommodation as an extension to their home. We can advise on design and technical issues to ensure a successful garage conversion project that integrates itself perfectly with your existing home.
