Melrose Designs – Affordable Architectural Plans for Home Extensions in Wigan and the North West.

SINGLE STOREY EXTENSION AND GARAGE CONVERSION – KILNGATE, PRESTON.
We were brought in by our client to help them in their ground floor rear kitchen extension in Kilngate, Lostock Hall. Our client was looking to extend the property to the rear as much as possible whilst still abiding by the Council’s current planning policies.
By extending out from the original extension and partially converting the garage to add a new utility and W.C. we were able to increase the floor area by a modest 20m² floor space to the property. Further to this, by removing the rear external wall, we were able to create a large open-plan kitchen and dining area.
The new rear extension boasts beautiful French doors overlooking the garden and provides ample natural daylight. We also re-configured the floor space at the front of the property, starting by converting the garage, we were able to create a much-desired new W.C. as well as providing somewhere to locate a new utility room.
