House Extensions
We can take on both single-storey and multi-storey house extensions. These can add a huge amount of value to your property, while giving you an extra bedroom, lounge or kitchen to enjoy. House extensions can be part of wider house refurbishments or a standalone project.
Loft Conversions
Many properties have spacious garages and lofts which are under-utilised, constituting extra storage for items that are rarely used. These have a huge amount of potential. They could be turned into an extra bedroom, home office, games room – whatever you can think of!
Renovations & Refurbishments
We have completed a variety of Kitchen, Bathroom & full home Renovations in and around Sutton & Wimbledon.
